The person who filled out the deposit slip received $88.79 in cash. The correct answer is option c.
To find out how much cash the person who filled out the deposit slip received, we need to fill in the missing amounts on the slip.
First, we need to calculate the subtotal by adding the amounts of the checks and cash:
Subtotal = 15.00 + 62.44 + 27.83 + 45.75
Subtotal = 151.02
Next, we need to determine the amount of cash received by subtracting the subtotal from the total:
Total = Subtotal - cash received
62.23 = 151.02 - cash received
To solve for cash received, we can subtract the total from the subtotal:
Cash received = Subtotal - total
Cash received = 151.02 - 62.23
Cash received = 88.79
Therefore, correct option is C.

Harrison works at a factory that makes paper cups for water coolers. He calculated the outer surface area of each hollow cup as 17.9 square inches. What is the approximate slant height of the cup?
Answer:
We can use the formula for the lateral surface area of a cone to find the slant height:
Lateral surface area = πrℓ, where r is the radius and ℓ is the slant height.
Since the paper cup is hollow, the lateral surface area is equal to the outer surface area of the cup, which is given as 17.9 square inches. The radius of the cup is half the diameter, which we do not know, so let's call it d:
r = d/2
We also know that the lateral surface area is given by:
17.9 = πrℓ
Substituting r = d/2, we get:
17.9 = π(d/2)ℓ
Simplifying, we get:
ℓ = (2*17.9)/(πd)
Using an approximation of π = 3.14, we can calculate:
ℓ ≈ (2*17.9)/(3.14d) = 11.40/d
Since we do not have any information about the diameter of the paper cup, we cannot calculate the exact slant height.

In a school of 425 pupils, there are 9 girls for every 8 boys. How many boys are there in the school?
The concept of ratio is used here to determine the number of boys in the school. Here the in a school of 425 pupils, the total number of boys in the school is 200.
Here there are 425 pupils, If the ratio of boys to girls is 8 to 9, then 8 out of 17 are boys and 9 out of every 17 are girls. Set up a proportion for the boys, where b = the total number of boys.
8 / 17 = b / 425
17 b = 8 × 425
b = 8 × 425 / 17
b = 200
So the number of boys are 200 and the number of girls are 425 - 200 = 225.

there are 200 students in cs6515, 140 are cs master students, 50 are cs phd students, and 30 are from other departments. if one choses a student at random until a cs phd student is selected, what is the expected number of choices needed?
The expected number of choices needed to select the first CS PhD student is 4.
To solve this problem, we can use the concept of geometric distribution. The geometric distribution represents the number of independent and identical trials that are needed to obtain the first success, where the probability of success is p.
In this case, the probability of selecting a CS PhD student on any given trial is 50/200 = 0.25. Therefore, the number of trials needed to obtain the first CS PhD student follows a geometric distribution with p = 0.25.
The expected value of a geometric distribution with parameter p is given by E(X) = 1/p. Therefore, the expected number of choices needed to select the first CS PhD student is
E(X) = 1/p = 1/0.25 = 4

d. None of the other answers is correct.
The correct alternative hypothesis in this case would be Ha: u not equal to 8, option a. This is because the null hypothesis in this scenario would be that the mean of the bottles of cream being filled is equal to 8 ounces.
The alternative hypothesis, on the other hand, is what we believe to be true if the null hypothesis is proven to be false. In this case, if we were to find evidence that the mean is not equal to 8 ounces, it would lead us to reject the null hypothesis and accept the alternative hypothesis that the mean is in fact different from 8 ounces.

Write an equation perpendicular to 5x + 3y = -21 that passes through the point (-5, 1).
Answer:
he desired equation is y = (3/5)x + 4
Step-by-step explanation:
Solving the given 5x + 3y = -21 for 3y yields 3y = -5x - 21. Dividing all three terms by 3, we get:
y = (-5/3)x - 7, indicating that the given line has slope -5/3.
The slope of a line perpendicular to this y = (-5/3)x - 7 is 3/5, the negative reciprocal of -5/3.
Start with y = mx + b. Substitute 1 for y, -5 for x and 3/5 for m. Then:
1 = (3/5)(-5) + b, or
1 = -3 + b. Then b must be 4, and so the desired equation is y = (3/5)x + 4.

Find the linear approximation of the function f(x)= sqrt (4-x) at a=0Use L(x) to approximate the numbers sqrt (3.9) and sqrt (3.99) Round to four decimal places
The linear approximation of f(x)= sqrt(4-x) at a=0 can be used to approximate sqrt(3.9) and sqrt(3.99) as 0.0500 and 0.0050, respectively.
The linear approximation of the function f(x)= sqrt(4-x) at a=0 is given by:
L(x) = f(a) + f'(a)(x-a)
= sqrt(4-0) + (-1/2)(x-0)
= 2 - 0.5x
To approximate the numbers sqrt(3.9) and sqrt(3.99) using L(x), we need to plug in the values of x and round the answer to four decimal places.
For sqrt(3.9), we have:
L(3.9) = 2 - 0.5(3.9)
= 0.05
Rounding to four decimal places, we get:
L(3.9) ≈ 0.0500
For sqrt(3.99), we have:
L(3.99) = 2 - 0.5(3.99)
= 0.005
Rounding to four decimal places, we get:
L(3.99) ≈ 0.0050
Therefore, the linear approximation of f(x)= sqrt(4-x) at a=0 can be used to approximate sqrt(3.9) and sqrt(3.99) as 0.0500 and 0.0050, respectively.
To find the linear approximation L(x) of the function f(x) = sqrt(4-x) at a=0, we need to calculate the value of the function and its derivative at a=0:
f(a) = f(0) = sqrt(4-0) = sqrt(4) = 2
Now, we find the derivative of f(x) with respect to x:
f'(x) = d/dx(sqrt(4-x)) = -1/(2*sqrt(4-x))
Next, evaluate f'(x) at a=0:
f'(0) = -1/(2*sqrt(4-0)) = -1/(2*2) = -1/4
The linear approximation L(x) is given by:
L(x) = f(a) + f'(a)(x-a)
L(x) = 2 - (1/4)(x-0) = 2 - (1/4)x
Now, we use L(x) to approximate sqrt(3.9) and sqrt(3.99):
L(0.1) = 2 - (1/4)(0.1) = 1.9750
L(0.01) = 2 - (1/4)(0.01) = 1.9975
So, the linear approximations of sqrt(3.9) and sqrt(3.99) are 1.9750 and 1.9975, respectively.

The director of a marketing department wants to estimate the proportion of people who purchase a certain product online. the director originally planned to obtain a random sample of 2,500 people who purchased the product. however, because of budget concerns, the sample size will be reduced to 1,500 people. What describes the effect of reducing the number of people in the sample?
Reducing the number of people in the sample from 2,500 to 1,500 will likely decrease the accuracy and precision of the estimate of the proportion of people who purchase the product online.
With a smaller sample size, there is a greater chance of sampling error and the results may not be representative of the entire population. The director should be aware that the smaller sample size may limit the reliability of the findings and consider adjusting the analysis accordingly.
The effect of reducing the number of people in the sample from 2,500 to 1,500 for the marketing department's study can be described as follows:
1. Decreased precision: By using a smaller random sample, the precision of the estimated proportion of people who purchase the product online will be reduced. This means that the range of possible values for the true proportion will be wider, leading to less certainty in the results.
2. Increased margin of error: With a smaller sample size, the margin of error will increase. This means that the range within which the true proportion lies will be larger, making it more difficult for the marketing department to make accurate predictions about online purchasing behavior.
3. Potential for increased bias: If the random sample of 1,500 people does not adequately represent the population of interest, the results may be more susceptible to bias. This could lead to inaccurate conclusions about the proportion of people who purchase the product online.
In summary, by reducing the sample size from 2,500 to 1,500 due to budget concerns, the marketing department will face a decrease in precision, an increase in the margin of error, and a potential for increased bias in their estimation of the proportion of people who purchase the product online.

The simple interest on a certain sum for 3 years is rupees 225 and the compound interest on the same sum at the same rate for 2 years is rupees 153 find the rate of interest and the principle
The principal amount is Rs. 468.75 and the rate of interest is 16% per annum.
How to solve for the principal amountAccording to the given information, the simple interest on the principal amount for 3 years is Rs. 225, so we have:
Simple Interest (S.I.) = P * r * t = 225
Substituting t = 3 years, we get:
P * r * 3 = 225
P * r = 75 --- (1)
Also, the compound interest on the same principal amount and at the same rate for 2 years is Rs. 153, so we have:
Compound Interest (C.I.) = [tex]P * (1 + r)^t - P = 153[/tex]
Substituting t = 2 years, we get:
[tex]P * (1 + r)^2 - P = 153P * [(1 + r)^2 - 1] = 153P * [(1 + r + r^2) - 1] = 153P * (r + r^2) = 153 / 2[/tex]--- (2)
Dividing equation (2) by equation (1), we get:
(r + r^2) / r = (153 / 2) / 75
Simplifying and solving for r, we get:
r^2 + r - 0.68 = 0
Using the quadratic formula, we get:
r = (-1 ± √(1 + 4 * 0.68)) / 2
r = (-1 ± 1.32) / 2
Since r cannot be negative, we take the positive value:
r = (0.32) / 2 = 0.16
Substituting r = 0.16 in equation (1), we get:
P * 0.16 = 75
P = 75 / 0.16 = Rs. 468.75
Therefore, the principal amount is Rs. 468.75 and the rate of interest is 16% per annum.
