A Bank Statement Is Shown. Fill In The Gaps To Complete The Sentence Below. This Bank Statement Shows

Answers

Answer 1

The bank statement  that is shown in the question shows a loss of £285.00 and calculated by subtracting the total expenses (money out) from the total revenue (money in).

Define profit or loss?

Profit or loss is a measure of the financial performance of a business, organization, or individual over a given period of time.

Profit refers to the positive difference between the revenue earned by a business or individual and the expenses incurred during a given period.

A loss occurs when the expenses incurred exceed the revenue earned during a given period.

To calculate the profit or loss, you need to subtract the total expenses (money out) from the total revenue (money in).

In this case, the total revenue is £315.00 + £265.00 + £190.00 = £770.00, and the total expenses are £210.00 + £30.00 + £450.00 + £100.00 = £790.00.

So, the calculation would be:

Total revenue - total expenses = profit/loss

£770.00 - £790.00 = -£20.00

Sarah took the advertising department from her company on a round trip to meet with a potential client. Including Sarah a total of 15 people took the trip. She was able to purchase coach tickets for ​$220 and first class tickets for ​$910. She used her total budget for airfare for the​ trip, which was ​$8130. How many first class tickets did she​ buy? How many coach tickets did she​ buy?

Answers

Let's use x to represent the number of coach tickets that Sarah purchased, and y to represent the number of first class tickets. Since a total of 15 people took the trip, we know that:

x + y + 1 = 15

where the extra 1 represents Sarah.

We also know that Sarah used her entire budget of $8130 for airfare, so we can write an equation for the cost of the tickets:

220x + 910y = 8130

Now we have a system of two equations with two variables. We can solve for x and y using substitution or elimination.

Using substitution, we can solve for x in terms of y from the first equation:

x + y + 1 = 15 => x = 14 - y

Substituting this expression for x into the second equation, we get:

220(14 - y) + 910y = 8130

3080 - 220y + 910y = 8130

690y = 5050

y = 7.319 (rounded to three decimal places)

Since we cannot purchase a fractional number of tickets, we need to round y to the nearest whole number. Since y represents the number of first class tickets, Sarah must have purchased either 7 or 8 first class tickets.

If she purchased 7 first class tickets, then the number of coach tickets would be:

x = 14 - y = 14 - 7 = 7

This would result in a total cost of:

220(7) + 910(7) = 6440

But since Sarah's budget was $8130, she must have purchased more first class tickets than this.

If she purchased 8 first class tickets, then the number of coach tickets would be:

x = 14 - y = 14 - 8 = 6

This would result in a total cost of:

220(6) + 910(8) = 7280

This is less than Sarah's budget of $8130, so it is a possible solution.

Therefore, Sarah purchased 8 first class tickets and 6 coach tickets.

Show that, the sum of an infinite arithmetic progressive sequence with a positive common difference

Answers

Answer:

Show that, the sum of an infinite arithmetic progressive sequence with a positive common difference

is +∞

Step-by-step explanation:

To show that the sum of an infinite arithmetic progressive sequence with a positive common difference is +∞, we can use the formula for the sum of the first n terms of an arithmetic sequence:

Sn = n/2 [2a + (n-1)d]

where a is the first term, d is the common difference, and n is the number of terms in the sequence.

Now, if we let n approach infinity, the sum of the first n terms of the sequence will also approach infinity. This can be seen by looking at the term (n-1)d in the formula, which grows without bound as n becomes larger and larger.

In other words, as we add more and more terms to the sequence, each term gets larger by a fixed amount (the common difference d), and so the sum of the sequence increases without bound. Therefore, the sum of an infinite arithmetic progressive sequence with a positive common difference is +∞.

The null hypothesis is rejected whenever:A. past studies prove it wrong. B. there is a low probability that the obtained results could be due to random error.C. the independent variable fails to have an effect on the dependent variable.D. the researcher is convinced that the variable is ineffective in causing changes in behavior.

Answers

The null hypothesis is rejected whenever "there is a low probability that the obtained results could be due to random error." The correct answer is Option B.

What is the null hypothesis?

The null hypothesis is a statistical hypothesis used to test the difference between two sample data groups. The null hypothesis is the hypothesis that the sample statistics are not significantly different. Any significant differences between the sample data are seen as supporting the alternative hypothesis.

A null hypothesis is often expressed as "no difference," "no correlation," or "no significant effect." For example, the null hypothesis for an experiment comparing two groups of people could be "there is no difference between the two groups." When the null hypothesis is rejected, it means that the results of the experiment are statistically significant, and the alternative hypothesis is supported.

Therefore, the null hypothesis is rejected whenever there is a low probability that the obtained results could be due to random error.

Answers

James bought a total of 7 yards of ribbon for his craft project.

To begin with, let's first convert the length of the ribbon from feet to yards. There are 3 feet in a yard. So, to convert 2.1 feet to yards, we need to divide it by 3.

2.1 feet ÷ 3 = 0.7 yards

So, each piece of ribbon is 0.7 yards long.

Now, let's calculate the total length of ribbon James bought by multiplying the length of each piece of ribbon by the total number of ribbons he bought.

We have that, using Euclid's algorithm, we find the inverse of 200 modules 1001 is -5 (or 1001+5).

How do we find the inverse of a modulus?

To find the inverse of a module m using Euclid's algorithm, the steps are as follows:

1. Calculate the greatest common divisor (GCD) of a and m using the Euclidean algorithm.

2. Let a = GCD * s + m*t, where s is the inverse of a module m.

3. The GCD in terms of a and my is written as 1 = m-s*a.

4. Find s = -a, so the inverse of a module m is -a (or m+s).

For example, a = 2, m=17, so GCD = 1 = 17-8*2 and the inverse of 2 modulo 17 is -8 (or 17+8). Similarly, for a = 34, m= 89, the GCD = 1 = 89-34*2 and the inverse of 34 modulo 89 is -34 (or 89+34). Finally, for a = 200, m= 1001, the GCD = 1 = 1001-5*200 and the inverse of 200 modulo 1001 is -5 (or 1001+5).

A restaurant bill of $3200 is paid with $500 and $1000 bills. If 16 bills were used, determine how many $1000 and $500 bills were used.​

Answers

Let's use variables to represent the number of $1000 and $500 bills used.

Let x be the number of $1000 bills used.

Then 16 - x is the number of $500 bills used.

The total amount paid is the sum of the values of the bills used:

$1000(x) + $500(16 - x) = $3200

Simplifying and solving for x:

$1000x + $8000 - $500x = $3200

$500x = $4800

x = 9.6

We can't have a fraction of a bill, so we'll round down to 9 $1000 bills.

Then the number of $500 bills used is:

16 - x = 16 - 9 = 7

Therefore, 9 $1000 bills and 7 $500 bills were used to pay the $3200 restaurant bill.

Therefore, we estimate that about 7 sixth graders should be chosen to create a representative sample, given that 9 seventh graders were chosen.

What is statistics?

Statistics is a branch of mathematics that involves the collection, analysis, interpretation, presentation, and organization of data. It provides methods for summarizing and describing data, making inferences about populations based on samples, and testing hypotheses. Statistics is used in many fields, such as business, economics, health care, social sciences, engineering, and more, to make decisions and draw conclusions based on data. Some common techniques used in statistics include descriptive statistics (e.g., mean, median, mode, standard deviation), probability theory, hypothesis testing, regression analysis, and sampling methods.

Here,

To estimate the number of sixth graders that should be chosen to create a representative sample, we can use the proportion of seventh graders in the sample and assume that the proportions of each grade in the sample should match the proportions in the population. We know that the sample contains 9 seventh graders, but we don't know the total size of the sample yet. We can use the following formula to estimate the sample size:

sample proportion = population proportion

where

sample proportion = number of seventh graders in the sample / total sample size

population proportion = number of seventh graders in the population / total population size

We can plug in the values we know:

9 / total sample size = 180 / (160 + 180 + 140)

Simplifying the right-hand side:

9 / total sample size = 0.4

Multiplying both sides by total sample size and simplifying:

total sample size = 9 / 0.4

total sample size ≈ 22.5

This means that the sample size should be about 22.5 students. Since we can't choose a fractional number of students, we should round up to the nearest whole number, giving a total sample size of 23 students.

To estimate the number of sixth graders in the sample, we can use the proportion of sixth graders in the population and assume that the proportion should be the same in the sample:

number of sixth graders in the sample / total sample size = 160 / (160 + 180 + 140)

Simplifying the right-hand side:

number of sixth graders in the sample / total sample size = 0.32

Multiplying both sides by total sample size and simplifying:

number of sixth graders in the sample = 0.32 * 23

number of sixth graders in the sample ≈ 7

The cost of petrol for the trip to UWC is R1.2384.

What is cost?

In general, cost refers to the amount of resources (usually money) that must be expended to produce or acquire something. It can be thought of as the value of the resources that are given up in order to obtain something else.

According to the given information:

To calculate the cost of petrol for the trip to UWC, we need to know the distance traveled and the amount of fuel consumed.

Let's assume that the distance from Andrew's home to UWC is 20 kilometers (km). Then, the amount of fuel consumed for the trip is:

[tex]Fuel consumed = (0.0052 k/100 km) * 20 km = 0.00104 k[/tex]

where k stands for liters of petrol.

To convert the amount of fuel consumed to liters, we need to multiply by 100, since the fuel consumption rate is given in liters per 100 km:

[tex]Fuel consumed = 0.00104 k * 100 = 0.104 liters\\Fuel consumed = 0.00104 k * 100 = 0.104 liters[/tex]

Now we can calculate the cost of petrol for the trip:

[tex]Cost of petrol = (0.104 liters) * (R11.90/liter) = R1.2384[/tex]

Therefore, the cost of petrol for the trip to UWC is R1.2384.

Suppose you roll a special 37-sided die. What is the probability that one of the following numbers is rolled? 35 | 25 | 33 | 9 | 19 Probability = (Round to 4 decimal places) License Points possible: 1 This is attempt 1 of 2.

Answers

Answer:

5/37

Step-by-step explanation:

There are 37 possible outcomes when rolling a 37-sided die, so the probability of rolling any one specific number is 1/37.

To find the probability of rolling any of the given numbers (35, 25, 33, 9, or 19), we need to add the probabilities of rolling each individual number.

Probability of rolling 35: 1/37

Probability of rolling 25: 1/37

Probability of rolling 33: 1/37

Probability of rolling 9: 1/37

Probability of rolling 19: 1/37

The probability of rolling any one of these numbers is the sum of these probabilities:

1/37 + 1/37 + 1/37 + 1/37 + 1/37 = 5/37

So the probability of rolling any of the given numbers is 5/37, which is approximately 0.1351 when rounded to four decimal places.

640,000 km ÷ 25,000 km/year = 25.6 years

Since Mavis will need to replace her tires once every 25.6 years, the cost of the wear on her tires for a single year is:

$140.00/tire * 4 tires = $560.00

So the total cost of the wear on Mavis’ tires for a year in which she drives 25,000 km is $560.00.

What is the area of this polygon in square units

Answers

The area of the polygon is 80 units².

What is a Polygon?

A polygon is a plane figure made up of line segments connected to form a closed polygonal chain. The segments of a closed polygonal chain are called its edges or sides.

Dividing the polygon into parts marked in the attached figure so as to calculate the area easily.

For triangle, DEF

Area = [tex]\frac{1}{2} bh[/tex]

        = [tex]\frac{1}{2}[/tex] × 3 × 4

       = 6 units²

For triangle BCD

Area = [tex]\frac{1}{2}bh[/tex]

        = [tex]\frac{1}{2}[/tex] × 2 × 4

        = 4 units²

For trapezoid ABFG,

Area = [tex]\frac{1}{2} (a + b) h[/tex]

        = [tex]\frac{1}{2}[/tex] × (5.5 + 12) × 8

        = 70 units²

Hence, total area = 6 + 4 + 70

                             = 80 units².

Therefore, the total area of the polygon is 80 units².

Factor

[tex]25x^6 + 10x^3 + 12[/tex]

Answers

Answer:

Step-by-step explanation:

To factor 25x^6 + 10x^3 + 12, we can first factor out the greatest common factor of the three terms which is 1, then use a substitution:

Let's substitute y = x^3. Then, the expression becomes:

25y^2 + 10y + 12

We can now try to factor this quadratic expression. However, since the discriminant (b^2 - 4ac) of this quadratic equation is negative (10^2 - 4*25*12 = -440), this expression cannot be factored using real numbers.

Therefore, the final answer for the factoring is:

25x^6 + 10x^3 + 12 = (unfactorable)

The linear function that models the data is y=3/5x - 2/5 which has the form y=mx+b, where m is the slope and b is the y-intercept.

What is linear function?

This can be written in the form y = mx + b where m and b are constants and x is a variable. The graph of a linear function is a straight line that goes through the origin.

To calculate the linear function, we must first calculate the slope. The slope is the numerical change in y (rise) divided by the numerical change in x (run).

Subtracting the y-values for x=-9 and x=-8, we get

-29/5 - (-26/5) = -3/5.

Similarly, subtracting the x-values for x=-9 and x=-8, we get

-9 - (-8) = -1.

Now, -3/5 / -1, we get the slope, m, of 3/5.

Next, we must calculate the y-intercept, b.

To do this, we can use either of the points given.

Using the points (x=-9, y=-29/5), we can substitute the x and y values into the linear equation, y=mx+b.

-29/5 = 3/5(-9) + b, which can be simplified to

-29/5 = -27/5 + b.

Adding 27/5 to both sides, we get b = -2/5.

Therefore, the linear function that models the data is y=3/5x - 2/5.

Which of the following statements most accurately describes the relationship between cultured yeast preparation conditions and fermented alcohol yield, based on passage data?Neither glucose concentration nor percentage yeast inoculate was positively correlated with fermented alcohol yield.A is correct. Table 1 shows that the maximum fermented alcohol yield was obtained in Broth A, with 10% glucose (not 12%, as in Broth C) and 8% yeast inoculate (not 10%, as in Broth B). Therefore, increasing neither glucose concentration nor percentage yeast inoculate led to more production of alcohol, so neither of those parameters showed a positive correlation with alcohol yield.

Answers

Based on the passage data, the most accurate statement describing the relationship between cultured yeast preparation conditions and fermented alcohol yield is: "Neither glucose concentration nor percentage yeast inoculate was positively correlated with fermented alcohol yield."

What this means is that increasing the concentration of glucose or percentage of yeast inoculate did not lead to more production of alcohol. The data in Table 1 shows that the maximum fermented alcohol yield was obtained in Broth A, which had 10% glucose and 8% yeast inoculation. Broth C, which had a higher concentration of glucose at 12%, did not result in a higher yield of alcohol. Similarly, Broth B, which had a higher percentage of yeast inoculate at 10%, did not lead to a higher yield of alcohol.

Therefore, it can be concluded that neither glucose concentration nor percentage of yeast inoculates was positively correlated with fermented alcohol yield.

Binomial Problem:A jury has 12 jurors. A vote of at least 10 out of 12 for "guilty" is necessary for a defendant to be convicted of a crime. Assume that each juror acts independently of the others and that the probability that any one juror makes the correct decision on a defendant is .80. If the defendeant is guitly, what is the probability that the jury makes the correct decision?

Answers

The probability that the jury makes the correct decision is approximately 0.7063.

To solve this problem, we need to find the probability that the jury makes the correct decision if the defendant is guilty. Let's break down the problem into smaller steps.

We know that the probability of a single juror making the correct decision is 0.80. If the defendant is guilty, then the probability of a juror making the correct decision is still 0.80. Therefore, the probability that a single juror makes the correct decision if the defendant is guilty is 0.80.

We can use the binomial distribution formula to determine the probability of at least 10 out of 12 jurors making the correct decision. The formula is:

P(X ≥ k) = 1 - Σ(i=0 to k-1) [n!/(i!(n-i)!) x [tex]p^i \times (1-p)^{(n-i)}[/tex] ]

where:

P(X ≥ k) is the probability of at least k successes

n is the total number of trials (in this case, 12 jurors)

p is the probability of success in a single trial (in this case, 0.80)

k is the number of successes we want to find the probability of (in this case, 10)

Plugging in the values, we get:

P(X ≥ 10) = 1 - Σ(i=0 to 9) [12!/(i!(12-i)!) x [tex]0.80^i \times (1-0.80)^{(12-i)}[/tex]]

Using a calculator or software, we can calculate this to be approximately 0.7063.

Answers

The probability of selecting another black marble is 3/7. As a result, the probability of drawing two black marbles in a row without replacement

(a) P(two red marbles) with replacement:The probability of drawing a red marble from a jar with five red marbles and four black marbles is 5/9, as there are five red marbles and nine total marbles. As a result, the probability of selecting two red marbles in a row with replacement is:P(two red marbles with replacement) = (5/9) × (5/9) = 25/81without replacement:When the first marble is removed, there are now only eight marbles remaining in the jar. Because there are only four black marbles in the jar, the probability of drawing a red marble is now 5/8. Therefore, the probability of selecting two red marbles in a row without replacement is:P(two red marbles without replacement) = (5/9) × (5/8) = 25/72(b) P(two black marbles)with replacement:For the first draw, there are four black marbles in the jar and a total of nine marbles. Therefore, the probability of drawing a black marble on the first draw is 4/9. Since the first marble was not removed, there are now eight marbles in the jar, including three black ones, and there are a total of nine marbles. Therefore, the probability of selecting another black marble is 3/9 or 1/3.

The probability of drawing two black marbles in a row with replacement is:P(two black marbles with replacement) = (4/9) × (1/3) = 4/27without replacement:Since the first marble was removed, there are only eight marbles in the jar, and there are four black ones. Therefore, the probability of selecting a black marble is 4/8 or 1/2. When the first black marble is removed, there are only seven marbles left, including three black ones. Therefore, the probability of selecting another black marble is 3/7. As a result, the probability of drawing two black marbles in a row without replacement is:P(two black marbles without replacement) = (4/9) × (3/7) = 12/63(c) P(one red and one black marble)with replacement:When one red and one black marble are selected with replacement, there are nine marbles in the jar for each draw. The probability of selecting one red and one black marble in a row is:P(one red and one black marble with replacement) = 2 × (5/9) × (4/9) = 40/81without replacement:Since there are five red and four black marbles in the jar, the probability of selecting a red marble first is 5/9. Once the red marble has been drawn and removed, there are only eight marbles remaining, including four black ones. As a result, the probability of selecting a black marble is 4/8 or 1/2.

As a result, the probability of drawing one red and one black marble without replacement is:P(one red and one black marble without replacement) = (5/9) × (4/8) + (4/9) × (5/8) = 20/36 + 20/36 = 10/18 = 5/9(d) P(red on the first draw and black on the second draw)with replacement:There are nine marbles in the jar for each draw. The probability of selecting a red marble first is 5/9. When the red marble is returned to the jar, there are still nine marbles in the jar, but now there are only four black marbles. The probability of selecting a black marble on the second draw is 4/9. As a result, the probability of drawing a red marble first and a black marble second with replacement is:P(red on the first draw and black on the second draw with replacement) = (5/9) × (4/9) = 20/81without replacement:Since there are five red and four black marbles in the jar, the probability of selecting a red marble first is 5/9. Once the red marble has been drawn and removed, there are only eight marbles remaining, including four black ones. As a result, the probability of selecting a black marble is 4/8 or 1/2. As a result, the probability of drawing a red marble first and a black marble second without replacement is:P(red on the first draw and black on the second draw without replacement) = (5/9) × (4/8) = 5/18
