Water flows into a lake at a constant rate.
Grace recorded that 400 litres of water flowed into the lake in 1 minute.
She recorded the number of litres to the nearest 20 litres.
She recorded the time to the nearest
10 seconds.
Calculate the upper bound for the rate at which the water could have flowed into the lake.
Give your answer in litres per second to 2 d.p.

Answers

The upper bound for the rate at which the water could have flowed into lake is 8.2 liters per second.

What is an upper bound?

An upper limit is a value that is larger than or equal to all the values in a set. In mathematics, it is used to specify a cap or a maximum value for a collection of data. For instance, an upper bound is frequently employed in optimization issues to place a cap on the highest value that a function or variable may take. Upper limits are used in statistics to specify a data set's maximum range which may be used to spot outliers or other abnormalities in the data. In calculus, upper bounds are used to specify a sequence's or series' limit, or the highest number that it may possibly approach.

Given that, 400 liters of water flowed into the lake in 1 minute.

The upper bound of water flow will be the maximum amount of water.

For the nearest measures taken by Grace the amount of water needs to ne more than 400, while the time must be less than 10 seconds from the recorded 1 min.

That is time must be 60 - 10 = 50 seconds.

Approximating the values we have:

410/50 = 8.2 liters per second.

Hence, the upper bound for the rate at which the water could have flowed into lake is 8.2 liters per second.

If thrice a number increased by 11, the result is 35. What is the number?

Answers

If thrice a number increased by 11 and the result is 35, then the number is 8

Let's call the number we're trying to find "x".

According to the problem, "thrice a number increased by 11" is equal to 35. So we can write this as an equation:

3x + 11 = 35

To solve for x, we need to isolate it on one side of the equation. We can start by subtracting 11 from both sides:

3x + 11 - 11 = 35 - 11

Simplifying the left side and evaluating the right side, we get:

3x = 24

Now we can solve for x by dividing both sides by 3:

3x/3 = 24/3

x = 8

Answers

D: "[tex]c_{1} = 10[/tex] and [tex]c_{2} = 2[/tex]" are programmer-defined constants for quadratic probing that cannot be used in a quadratic probing equation. Option D is correct answer.

The quadratic probing equation is defined as:

h (k, i) = (h′(k) + [tex]c_{1}[/tex] * i + [tex]c_{2}[/tex] * i^2) mod m,

where h′(k) is the hash value of key

k and m is the size of the hash table.

The constants [tex]c_{1}[/tex] and [tex]c_{2}[/tex] are programmer-defined constants that are used to compute the new hash index when a collision occurs in the hash table.

The given hash function is h(k) = k % 10.

Therefore, the hash value of any key will be between `0` and `9`.Now, let's check which of the given programmer-defined constants for quadratic probing cannot be used in a quadratic probing equation:

Option A: `c1 = 1 and c2 = 0`This option can be used in the quadratic probing equation. It means that linear probing is being used.

Option B: [tex]c_1 = 5[/tex] and [tex]c_2 = 1[/tex] This option can be used in the quadratic probing equation. It means that the new index is being computed as `h(k, i) = (h′(k) + 5i + i^2) mod m`.

Option C: [tex]c_1 = 1[/tex] and [tex]c_2 = 5[/tex] This option can be used in the quadratic probing equation. It means that the new index is being computed as `h(k, i) = (h′(k) + i + 5i^2) mod m`.

Option D: [tex]c_1 = 10[/tex] and [tex]c_2 = 2[/tex] This option cannot be used in the quadratic probing equation. It means that the new index is being computed as `h(k, i) = (h′(k) + 10i + 2i^2) mod m`.

Since [tex]c_{1}[/tex] is greater than or equal to `m`, this equation will always result in a hash index that is greater than or equal to `m`. Therefore, it is not possible to use `[tex]c_{1}[/tex]= 10` in the quadratic probing equation. Hence, the correct option is D.

Answers

The height of water in the tank in feet after t seconds can be expressed as h(t) = H - (Aw/Ah) 2gh t2, where Aw and Ah are the cross-sectional areas of the water and the hole in square feet respectively,

and g is the gravitational acceleration (32 ft/s2). The interval of definition for h(t) is 0 ≤ t ≤ H/2gh.

The graph of h(t) is a parabola with its vertex at (H/2gh, H) and is symmetric about the line t = H/2gh. It starts at (0, H) and gradually decreases to (H/2gh, 0).

Given the tank is 11 ft high, has radius 2 ft and the circular hole has radius in, and it is initially full, the time it will take to empty can be calculated as: t = √(2H/gAh) = √(22/(32 x π(0.52))) = 3.87 seconds. Therefore, it will take approximately 3.87 seconds to empty.

The length of a rectangular room is 9 feet longer than twice the width. If the​ room's perimeter is 150 ​feet, what are the​ room's dimensions?

Answers

Answer:

Length = 53 feet

Width = 22 feet

Step-by-step explanation:

Perimeter = 2(length + width)

Then:

a = 2w + 9            Ec. 1

150 = 2(a + w)       Ec. 2

a = length

w = width

From Eq. 1:

a - 9 = 2w            Eq. 3

From Eq. 2:

150 = 2*a + 2*w

150 = 2a + 2w

150 - 2a = 2w        Eq. 4

Equalizing Eq. 3 and Eq. 4

a - 9 = 150 - 2a

a + 2a = 150 + 9

3a = 159

a = 159/3

a = 53

From Eq. 1:

a = 2w + 9

53 = 2w + 9

53 - 9 = 2w

44 = 2w

44/2 = w

w = 22

Check:

From Eq. 2

150 = 2(a+w)

150 = 2(53+22)

150 = 2*75

Answers

The Riemann sum is:Σ(3-xᵢₖ*yᵢₖ²)ΔA, where i=1,2 and k=1,2,3.

We can create a Riemann sum to estimate the value of the double integral ∬R (3-xy²) dA over the rectangular region R=[0, 4]×[-1, 2] by subdividing [0, 4] into m=2 intervals and [-1, 2] into n=3 intervals. Then we can evaluate the function at the upper left corner of each subrectangle, multiply by the area of the rectangle, and sum all the results.

The width of each subinterval in the x-direction is Δx=(4-0)/2=2, and the width of each subinterval in the y-direction is Δy=(2-(-1))/3=1. The area of each subrectangle is ΔA=ΔxΔy=2*1=2.

Therefore, the Riemann sum is:

Σ(3-xᵢₖ*yᵢₖ²)ΔA, where i=1,2 and k=1,2,3.

Evaluating the function at the upper left corner of each subrectangle, we get:

(3-0*(-1)²)2 + (3-20²)2 + (3-21²)2 + (3-41²)*2 = 2 + 6 + 2 + (-22) = -12.

Answers

Most correlational studies use d)relative data, which compares two variables.

This means that one variable is being measured against another, often in the form of ratios or percentages. For example, one might compare the number of people who smoke cigarettes with the number of people who develop lung cancer, in order to determine whether there is a correlation between the two.

Relative data allows researchers to examine the relationship between variables, allowing them to assess the strength of the relationship between them.

In order to compare variables, correlational studies rely on either primary or secondary data. Primary data is collected through direct observation and experimentation, while secondary data is obtained from existing sources.

In most cases, correlational studies use secondary data, such as survey results or statistics from public databases. This data is often in the form of relative data, such as percentages or ratios.

By using relative data, correlational studies can determine the strength of the relationship between two variables. This information can be used to better understand how the variables are related, as well as to draw conclusions about their relationship. For example, the relationship between smoking and lung cancer can be examined using relative data, allowing researchers to identify patterns and draw conclusions about the correlation between the two variables.

Water freezes at 0º Celsius and 32º Fahrenheit. It boils at 100ºC and 212ºF. a) Find a linear function C that expresses temperature in the Celsius scale in terms of degrees Fahrenheit. b) Use this function to convert 110ºF into Celsius.

Answers

a) To find a linear function that expresses temperature in Celsius in terms of degrees Fahrenheit, we need to use the formula for converting Fahrenheit to Celsius:

C = (F - 32) * 5/9

This formula shows that to convert Fahrenheit to Celsius, we first subtract 32 from the Fahrenheit temperature, then multiply by 5/9.

If we rearrange this formula, we can solve for C in terms of F:

C = (F - 32) * 5/9

C = 5/9 * F - 5/9 * 32

C = 5/9 * F - 160/9

So the linear function C that expresses temperature in Celsius in terms of degrees Fahrenheit is:

C = 5/9 * F - 160/9

b) To use this function to convert 110ºF to Celsius, we simply substitute F = 110 into the equation:

C = 5/9 * F - 160/9

C = 5/9 * 110 - 160/9

C = 61.11ºC

Therefore, 110ºF is equivalent to 61.11ºC.

Answer:

a) To find a linear function that expresses temperature in Celsius in terms of degrees Fahrenheit, we can use the formula:

C = (F - 32) * 5/9

where C is the temperature in Celsius and F is the temperature in Fahrenheit.

b) To convert 110ºF to Celsius, we can plug in F = 110 into the formula above and simplify:

C = (110 - 32) * 5/9

C = 78 * 5/9

C = 43.33ºC

Therefore, 110ºF is equivalent to 43.33ºC in Celsius.

The rectangular garden is 175 m long and 96 m broad . find the cost of fencing it at 17.50per m.also find the cost of ploughing it at 4.50 paise per square metre

Answers

Hence, the cost of fencing the garden is ₹9485. Hence, the cost of plowing the garden is ₹756.

What is perimeter?

Perimeter is the total distance around the outside of a closed two-dimensional shape. It is the sum of the lengths of all the sides of the shape. For example, the perimeter of a rectangle is found by adding the lengths of all its four sides, whereas the perimeter of a circle is found by multiplying the diameter by π (pi). Perimeter is usually expressed in units of length, such as meters, centimeters, feet, or inches.

Here,

The perimeter of the rectangular garden is twice the sum of its length and width. So, the length of the fence needed to enclose the garden is:

2 × (length + width) = 2 × (175 m + 96 m) = 542 m

Therefore, the cost of fencing the garden at 17.50 per meter is:

Cost of fencing = length of fence × cost per meter

= 542 m × 17.50

= 9485

Hence, the cost of fencing the garden is ₹9485.

To find the cost of plowing the garden, we need to first calculate its area, which is given by:

Area = length × width

= 175 m × 96 m

= 16800 m²

Therefore, the cost of plowing the garden at 4.50 paise per square meter is:

Cost of plowing = area of garden × cost per square meter

= 16800 m² × 0.045

Answers

Total number of seats that remain unsold are 168.

What is statistics?

The branch of mathematics dealing with data collection, organization, analysis, interpretation and presentation.

Let's start by defining some variables to represent the unknowns in the problem:

Let x be the number of $30-seats.Let y be the number of $50-seats.

From the problem, we know that:

The total number of seats is 1050: x + y = 1050.There were 50% fewer $50-seats than $30-seats: y = 0.5x.90% of the $30-seats and some $50-seats were sold, which means that the revenue from the $30-seats is 0.9(30x) = 27x, and the revenue from the $50-seats is 0.9(50y) = 45y.

We also know that the total revenue collected is $34,650:

27x + 45y = 34650

Now we can substitute y = 0.5x from the second equation into the third equation and simplify:

27x + 45(0.5x) = 34650

27x + 22.5x = 34650

49.5x = 34650

x = 700

So there were 700 $30-seats and 350 $50-seats.

The number of sold $30-seats is 0.9(30x) = 567, and the number of sold $50-seats is 0.9(50y) = 315.

Therefore, the total number of seats sold is 882, and the number of unsold seats is:

Answers

He mean salary at a local industrial plant is $27,600 with a standard deviation of $5400 . the median salary is $25,200 and the 61st percentile is $29,100, The amount Tom earns (in dollars) is $31,590.

How do we calculate the amount Tom earns?

Given that, the mean salary at a local industrial plant is $27,600The standard deviation of salary is $5400The median salary is $25,200The 61st percentile is $29,100We have to find the amount that Tom earns (in dollars) if Tom's salary has a z-score of 0.7.

We need to calculate the z-score using the formula,[tex]Z = (X - \mu) / \sigma[/tex], where X is the value, μ is the mean and σ is the standard deviation. [tex]z = (X - \mu) / \sigma 0.7 = (X - 27,600) / 5,400[/tex] Multiplying both sides by 5,400, we get,0.7 × 5,400 = X - 27,600 Add 27,600 on both sides, we get, [tex]X = (0.7 * 5,400) + 27,600= 3,780 + 27,600= $31,590[/tex] Therefore, The amount Tom earns (in dollars) is $31,590.

what is histogram ?

A graph that displays the distribution of a collection of continuous data is called a histogram. It is composed of a number of bars, each of which represents a set of values, and whose height denotes the frequency or number of data points that lie within a given range. Histograms are used to depict a distribution's shape, centre, and spread graphically. They are frequently used to find patterns and trends in data in areas like statistics, data analysis, and scientific study.

the classification of student class designation (freshman, sophomore, junior, senior) is an example of a) a categorical random variable. b) a discrete random variable. c) a continuous random variable. d) a parameter.

Answers

The classification of student class designation (freshman, sophomore, junior, senior) is an example of a categorical random variable.  The correct option is A.

What is a random variable?

A random variable is a numerical or categorical quantity whose value is unknown but whose behavior can be forecast based on data that has been measured or observed. Random variables are typically used to represent quantities that fluctuate over time or are subject to chance occurrences.

The types of random variables are as follows:

i) Categorical random variable: This type of variable contains categorical data or data that are descriptive in nature. It is used to classify items or events into categories, which can be named or identified. For example, a set of data that includes categories like gender, eye color, or country of origin.

ii) Discrete random variable: This type of variable takes on discrete values, which means it can only take on whole numbers. For example, the number of cars sold at a dealership on any given day is a discrete random variable because it can only take on integer values.

iii) Continuous random variable: This type of variable takes on continuous values, which means it can take on any value within a given range. For example, the temperature in a room can take on any value between a certain minimum and maximum value.

Therefore, the correct option is A.

17. When preparing a sweet, sugar and flour are mixed in the ratio 2:3 and flour and butter are mixed in the ratio 3:1. If 200 g of sugar is used, find the mass of butter used to make the sweet.​

Answers

Step 1: Calculate the total amount of flour used.

200 g of sugar is used, so the amount of flour used is 300 g (because it follows the ratio 2:3).

Step 2: Calculate the amount of butter used.

Since flour and butter are mixed in the ratio 3:1, for every 3 units of flour, 1 unit of butter is used. So for 300 g of flour, 100 g of butter should be used.

Therefore, the mass of butter used to make the sweet is 100 g.

But because of horizontal mergers and acquisitions, most of them are owned by just a few large corporations like MegaCorp who each own multiple soup brands. Healthy and Hearty Soups and the other big national brands spend several million dollars on an advertising campaign, which smaller or independent soup brands cant do, so their share of the soup market is very small - if they survive at all.
