a market sells five kinds of cups, 4 kinds of saucers, and 2 kinds of spoons. How many ways are there to buy two objects of different types?

Answers

Answer 1

There are 84 ways to buy two objects of different types.

How to choose two objects of different types ?

To choose two objects of different types, we can choose one type of object first and then choose one object from that type and one object from the other two types.

The number of ways to choose one type of object is 3 (cups, saucers, or spoons). For each type of object, there are different numbers of objects to choose from:

Cups: 5 objectsSaucers: 4 objectsSpoons: 2 objects

So, the total number of ways to choose two objects of different types is:

3 x (5 x 4 + 5 x 2 + 4 x 2) = 3 x 28 = 84

Therefore, there are 84 ways to buy two objects of different types.

what two numbers add to -11 but multiply to -180

Answers

First let's start with the equation:

x + y = -11

xy = -180

We can substitute -11 in for x + y to get:

xy = -180

x(-11) = -180

Now let's divide both sides by -11

x = 180/11

x ≈ 16.36

We can now use the equation x + y = -11 to solve for y

y = -11 - 16.36

y ≈ -27.36

The two numbers that add to -11 but multiply to -180 are 16.36 and -27.36.

Define about the ratios of the numbers?

A ratio in mathematics is a correlation of at least two numbers that shows how big one is in comparison to the other. The dividend or number being divided is referred to as the antecedent, and the divisor or integer that is dividing is referred to as the consequent.

A ratio compares two numbers by division. Comparing one quantity to the total, for example the dogs that belong to all the animals in the clinic, is known as a part-to-whole analysis. These kinds of ratios occur considerably more frequently than you might imagine.

suppose that each day the price of a stock moves up 1/8th of a point with probability 1/3 and moves down 1/8th of point with probability 2/3. if the price fluctuations from one day to another are independent, what is the probability that after 6 days the stock has its original price?

Answers

After 6 days, the probability that the stock has its original price is 5/16.

There are two possible scenarios that can take place when the stock price fluctuates from one day to the next. Either the price goes up by 1/8th of a point with probability 1/3 or it goes down by 1/8th of a point with probability 2/3.

The price of the stock after six days can be denoted as S6. The price of the stock after the first day can be represented as S0.

Since the price fluctuates either up or down by 1/8th of a point on each day, the price after six days can be represented as follows:S6 = S0 + (up, up, up, up, up, up), (up, up, up, up, up, down), (up, up, up, up, down, up), ... , (down, down, down, down, down, down)

In order to return to the original price, the stock must go up and down by the same amount. As a result, there must be an equal number of ups and downs in the six-day period.

As a result, we must calculate the probability of obtaining an equal number of ups and downs over six days.

Let's represent an increase in the stock price as 'U' and a decrease as 'D.'

The total number of ways in which the stock can go up and down over six days is [tex]2^6 = 64[/tex].

The total number of ways in which the stock can return to its original price can be calculated as follows: [tex]N(UUUDDD) = 6! / (3! * 3!) = 20[/tex]

The probability of the stock returning to its original price after six days can be calculated as:

[tex]P = N(UUUDDD) / 64 = 20 / 64 = 5 / 16[/tex]

Therefore, the probability that after 6 days the stock has its original price is 5/16.

Answers

Jake is presently [tex]0[/tex] years old and the year is [tex]2036[/tex], which is not a relevant response or there may be some missing details in the question.

By year, what do you mean?

A span of time that is equivalent to one year on the Calender but starts at a different period. A cycle of 365 and 366 day split into twelve month starting in January and ending in December.

In arithmetic, how much is a month?

Every monthly on the calender has four complete weeks since every month has at least 28 days. A few month have a few more days, but these extra days don't add up to a full week, therefore they aren't counted.

Let's first find the current year, given that the year in which their ages will sum up to [tex]16x[/tex] is[tex]2036[/tex].

[tex]2036 - (y - 2036) = 2*2036 - y[/tex]

Simplifying this expression, we get:

[tex]2*2036 - y = 4072 - y[/tex]

[tex]2y = 4072[/tex]

[tex]y = 2036[/tex]

Now, let's find Jake's current age by subtracting his birth year from the current year [tex]y - (2036 - 7x)[/tex]

Since their ages sum up to 16x in 2036, we have:

[tex]x + 7x = 16x[/tex]

[tex]8x = 16x[/tex]

[tex]x = 0[/tex]

Find the height of an open cylinder of radius of 8cm given that it has a curved surface area of 1000cm²

Answers

The height of an open cylinder of radius of 8cm given that it has a curved surface area of 1000 cm² is equals to the 159.24 cm.

The area obtained after substracting the circular area from the total area of the cylinder is called as curved surface area. Curved surface area is calculated by formula, 2πrh

where r --> radius of cylinder

h --> height of cylinder

π --> math special constant

We have an open cylinder with the following dimensions,

Radius of cylinder, r = 8 cm

Curved surface area of cylinder, A = 1000 cm². We have to calculate the height of this open cylinder. Let the height of an open cylinder be 'h cm' . Using the above formula, height of cylinder, h = curved Area/ 2πr

=> h = A/2π

=> h = 1000/2 ( 3.14)

=> h = 1000/6.28

=> h = 159.24

Hence, required value of height is 159.24 cm.

The difference between the perimeters of these two castles is 28 ft.

Rory’s castle measures 10 feet by 16 feet and has a perimeter of 52 ft and Mike’s castle is 6 feet by 6 feet. Now, we are going to find the difference between the perimeters of these two castles.

The perimeter of a rectangle can be found by adding all the sides of a rectangle. Therefore, the formula of the perimeter of a rectangle is:

Perimeter of a rectangle = 2 × (Length + Breadth)

Length of Rory’s castle = 16 ft,       Breadth of Rory’s castle = 10 ft

Perimeter of Rory’s castle = 2 × (Length + Breadth) = 2 × (16 + 10) ft

= 2 × 26 ft= 52 ft

Therefore, the perimeter of Rory’s castle is 52 ft.

Length of Mike’s castle = 6 ft,         Breadth of Mike’s castle = 6 ft

Perimeter of Mike’s castle = 2 × (Length + Breadth) = 2 × (6 + 6) ft

= 2 × 12 ft = 24 ft

Therefore, the perimeter of Mike’s castle is 24 ft.

.Difference between the perimeters of these two castles= Perimeter of Rory’s castle − Perimeter of Mike’s castle

ten drill bits are randomly selected from a process. the times to failure (i.e., loss of acceptable sharpness) for the bits are recorded as 37, 39, 42, 43, 49, 50, 54, 55, 59, and 63 hours. assuming the failure times have a weibull distribution, analyze the data using probability plotting. estimate the shape and scale parameters. plot the original data versus the cdf model corresponding to your parameter estimates. add confidence limits.

Answers

In probability plotting, a graph of the cumulative distribution function (CDF) is plotted against a transformed version of the data to determine if the data come from a particular distribution.

The distance between the two lines is equal to the product of the critical value of the t-distribution and the standard error estimate.

This can be used to analyze the times to failure (i.e., loss of acceptable sharpness) for a random selection of ten drill bits from a process that follows a Weibull distribution.

To estimate the shape and scale parameters

follow these steps:

Step 1: Rank the data from smallest to largest

Step 2: Calculate the failure probability of each data point using the formula: i/(n+1), where i is the rank of the data point and n is the number of data points.

Step 3: Transform the failure probabilities using the inverse Weibull distribution function: F^(-1)(p) = (−ln(1−p))^β for a given shape parameter β and scale parameter η.

Step 4: Plot the transformed data against the theoretical distribution, which is a straight line for the Weibull distribution.

Step 5: Find the best-fitting line by eye, or by using regression analysis.

The slope of the line is equal to the shape parameter β, and the intercept is equal to the logarithm of the scale parameter ln(η).

The Weibull distribution can be represented as:[tex]F(x) = 1 − e^(-(x/η)^β)[/tex], where β is the shape parameter and η is the scale parameter. The CDF model corresponding to your parameter estimates can be plotted by using the formula . This can be done by calculating the standard deviation of the residuals, and then calculating the upper and lower limits of the confidence interval using the t-distribution.

The confidence interval can be calculated as:β ± t(n−2,α/2) x SE(β)ln(η) ± t(n−2,α/2) x SE(ln(η))where SE(β) is the standard error estimate for the shape parameter, SE(ln(η)) is the standard error estimate for the logarithm of the scale parameter, and t(n−2,α/2) is the critical value of the t-distribution with n−2 degrees of freedom and a significance level of α/2.The confidence limits can be plotted as two parallel lines around the best-fitting line. The distance between the two lines is equal to the product of the critical value of the t-distribution and the standard error estimate.

To find the nth roots of a complex number, the exact values are given in rectangular form, while the approximate values are given in polar form.

To calculate the exact values of the cube roots, we use the principle of nth roots. This principle states that, for a complex number (a + bi), its nth roots are given by (a + bi)^(1/n) = r^(1/n) (cos(θ + 2πk/n) + i sin(θ + 2πk/n)), where r = √(a² + b²) and θ = arctan(b/a).

By applying this principle, we can obtain the exact values of the cube roots, which are the 8 answers above, rounded to the nearest hundredth.

Simplify the expression. csc^2x-1/1+sin x
A. csc x+1
B. csc x(csc x-1)
C. sin^2x-csc x
D. csc^2x-cos x tan x

Answers

Answer:

We can start by simplifying the numerator of the expression:

csc^2x - 1 = (1/sin^2x) - 1 = (1 - sin^2x) / sin^2x = cos^2x / sin^2x = cos^2x csc^2x

Now we can substitute this into the original expression:

csc^2x-1/1+sin x = (cos^2x csc^2x) / (1 + sin x)

We can then simplify this further by using the identity 1 + sin x = (sin^2x + cos^2x) / sin x:

(cos^2x csc^2x) / (1 + sin x) = (cos^2x csc^2x) / [(sin^2x + cos^2x) / sin x]

= cos^2x csc^2x sin x / (sin^2x + cos^2x)

= cos^2x csc^2x sin x / 1

= cos^2x csc^2x sin x

This expression can be simplified using the identity cos^2x = 1 - sin^2x:

cos^2x csc^2x sin x = (1 - sin^2x) csc^2x sin x = (1/sin^2x - 1) sin x = csc^2x - sin x

Therefore, the simplified expression is csc^2x - sin x. Answer: none of the given options.

It is given that quadrilateral abcd is a kite. we know that ad ≅ cd by the definition of . by the kite diagonal theorem, ac is to bd this means that angles aed and ced are right angles. we also see that ed ≅ ed by the property. therefore, we have that δaed ≅ δced by .

Answers

By the congruence postulate, we have shown that the quadrilateral is  ΔAED ≅ ΔCED.

Let's start by showing that AD = CD. Since AB = AD and BC = CD, we can rewrite AB + BC as AD + CD. This means that AD = AB + BC - CD. But we know that AB = AD, so we can substitute AD for AB to get AD + BC = 2AD + CD. Simplifying this equation, we get AD = CD.

Next, we can show that AE = CE. Since AC is a diagonal of the kite, we know that AC bisects angle BAD and angle BCD. This means that angle BAC = angle DAC and angle BDC = angle CDC. Since AD = CD, we know that triangle ACD is isosceles, so angle ACD = angle CAD.

Using these angle equalities, we can conclude that angle CAE = angle CDE. Since AC ⊥ BD, we know that angle CAD = angle CDE, so we can conclude that triangle ACE is isosceles, which means that AE = CE.

Finally, we need to show that angle AED = angle CED. Since AD = CD and AE = CE, we know that triangles AED and CED have two pairs of congruent sides. Additionally, we know that AC is a common side of the triangles.

Since AC is perpendicular to BD, we know that angle ACD and angle BDC are complementary angles.

This means that angle ACD = 90 - angle BDC and angle CAD = 90 - angle BAC. Using these angle equalities, we can conclude that angle AED = angle CED.

Manipulate the triangle so angle a measures 41° and angle c measures 49°. what is the approximate measure of angleb? mangleb = ° what is the sum of the interior angles of the triangle? °

Answers

The approximate measure of angle B is 90°. The sum of the interior angles of the triangle is 180°.

The first part of your answer is correct. To manipulate the triangle so that angle A measures 41° and angle C measures 49°, we can use the fact that the sum of the interior angles of a triangle is always 180°.

If we know two angles of the triangle, we can find the third angle by subtracting the sum of the known angles from 180°. So, to find the measure of angle B, we can use the equation:

angle A + angle B + angle C = 180°

Substituting in the given angle measures, we get:

41° + angle B + 49° = 180°

Simplifying, we get:

angle B = 90°

Therefore, the approximate measure of angle B is 90°.

For the second part of your answer, the correct answer is 180°. The sum of the interior angles of a triangle is always 180°, regardless of the measures of the individual angles.

If the cost of 7m is Rs. 1470, find the cost of 5m cloth

Answers

By using unitary method, we found that the cost of 5m cloth is Rs. 1050.

According to the unitary method, the cost of 1 meter of cloth is equal to the total cost of 7 meters of cloth divided by 7. That is,

Cost of 1m cloth = Total cost of 7m cloth/7

We know that the total cost of 7m cloth is Rs. 1470. Therefore,

Cost of 1m cloth = 1470/7

Cost of 1m cloth = Rs. 210

This means that the cost of 1 meter of cloth is Rs. 210. Now, we need to find the cost of 5m cloth. To do that, we can use the unitary method again.

Cost of 5m cloth = Cost of 1m cloth x 5

Cost of 5m cloth = Rs. 210 x 5

Cost of 5m cloth = Rs. 1050

Therefore, the cost of 5m cloth is Rs. 1050.

On Monday, Elise walked 9. 9 kilometres. On Tuesday, she walked 0. 7 kilometres less than she had walked on Monday. How far did Elise walk on Tuesday?

Answers

Elise walked a distance of 9.2 kilometers on Tuesday.

To solve the problem, we need to first understand the information provided.

On Monday, Elise walked a distance of 9.9 kilometers.

On Tuesday, she walked a distance that was 0.7 kilometers less than what she walked on Monday.

This means that we need to subtract 0.7 kilometers from the distance that she walked on Monday to find the distance she walked on Tuesday.

To do this, we can use subtraction. We start by writing down the distance Elise walked on Monday, which is 9.9 kilometers, and then subtract 0.7 kilometers from it.

9.9 km - 0.7 km = 9.2 km

Answer:

x = 19

y = 16

Step-by-step explanation:

10x - 9y = 46

-2x + 3y = 10

Time the second equation by 5

10x - 9y = 46

-10x + 15y = 50

6y = 96

y = 16

Now put in 16 for y and solve for x

10x - 9(16) = 46

10x - 144 = 46

10x = 190

x = 19

given the speeds of each runner below, determine who runs the fastest. stephanie runs 8 feet per second. stephanie runs 8 feet per second. katie runs 463 feet in 32 seconds. katie runs 463 feet in 32 seconds. jessica runs 1 mile in 555 seconds. jessica runs 1 mile in 555 seconds. noah runs 728 feet in 1 minute. noah runs 728 feet in 1 minute.

Answers

Katie runs the fastest at 14.469 ft/s

To compare the speeds of each runner, we need to convert all the measurements to the same units. Let's convert them all to feet per second:

Stephanie runs 8 feet per second (8 ft/s)Katie runs 463 feet in 32 seconds, so her speed is (463 ft / 32 s) = 14.469 feet per second (14.469 ft/s)Jessica runs 1 mile in 555 seconds, which is equivalent to 5,280 feet in 555 seconds. Her speed is (5,280 ft / 555 s) = 9.514 feet per second (9.514 ft/s)Noah runs 728 feet in 1 minute, which is equivalent to (728 ft / 60 s) = 12.133 feet per second (12.133 ft/s)

Therefore, in order of fastest to slowest runner:

Katie (14.469 ft/s)

Noah (12.133 ft/s)

Stephanie (8 ft/s)

Jessica (9.514 ft/s)

Hence, Katie runs the fastest
