If a class of 27 students had a mean of 72 on a test, interpret the mean of 72 in the sense of a fair share measure of the center of the test scores.
The fair share measure would mean that the score of 72 would be the score all 27 students got on the test if they all had the same score.
A fair share measure of the center of the test scores is 72 be the score all 27 students got on the test.
We have given that
a class of 27 students had a mean of 72 on a test,
What is the fair share?An equitable or reasonable portion or share of something
The fair share measure would mean that a score of
72 be the score all 27 students got on the test.
If they all had the same score.
Therefore 72 was the score all 27 students got on the test.

After school Philippe spent 1 3/4 hours at baseball practice, 2 1/4 hours on homework, and 1/4 hour getting ready for bed. About how many hours after school will he be ready for bed. Explain
Answer:
4 hours. 1 3/4 is about 2, and 2 1/4 rounds to 2. 1/4 would round to 0, but it would not affect the estimate's accuracy much because we rounded up by 1/4 on 1 3/4 already. Philipe spent about 4 hours on activities.

Scott drinks 6 cups of water a day. How many fluid ounces of water does Scott drink? (2 points)
Group of answer choices
36 fluid ounces
48 fluid ounces
52 fluid ounces
68 fluid ounces if your right I give u a lot of points
There are 48 fluid ounces of water Scott drink.
Define the term ounces?An ounce is a unit of measurement of weight or mass in both the US customary system and the British imperial system. In the US customary system, one fluid ounce of water weighs about 1.04 ounces (oz).
Each day, Scott consumes 48 fluid ounces of water.
To convert cups to fluid ounces, we need to multiply the number of cups by 8 (as there are 8 fluid ounces in one cup).
So, 6 cups of water is equal to:
6 cups × 8 fluid ounces per cup = 48 fluid ounces
Therefore, there are 48 fluid ounces of water Scott drink.

Pilot Shop is a catalog business providing a wide variety of aviation products to pilots throughout the world. Maynard Shephard, the recently hired assistant controller, has been asked to develop a cost function to forecast shipping costs. The previous assistant controller had forecast shipping department costs each year by plotting cost data against direct labor-hours for the most recent 12 months and visually fitting a straight line through the points. The results were not satisfactory.
After discussions with the shipping department personnel, Maynard decided that shipping costs could be more closely related to the number of orders filled. He based his conclusion on the fact that 10 months ago the shipping department added some automated equipment. Furthermore, he believes that using linear regression analysis will improve the forecasts of shipping costs. Cost data for the shipping department have been accumulated for the last 25 weeks. He ran two regression analyses of the data, one using direct labor-hours, and one using the number of cartons shipped. The information from the two linear regressions follows:
Regression 1 Regression 2
Equation SC = 804.3 + 15.68DL SC = 642.9 + 3.92NR
R-squared .365 .729
Standard error of the estimate 2.652 1.884
t-value 1.89 3.46
where:
SC = total shipping department costs DL = total direct labor-hours
NR = number of cartons shipped
Required
1. Identify which cost function (regression 1 or regression 2) Pilot Shop should adopt for forecasting total shipping department costs and explain why.
2. If Pilot Shop projects that 600 orders will be filled the coming week, calculate the total shipping depart- ment costs using the regression you selected in requirement 1.
3. Explain two or three important limitations of the regression you selected in requirement 1, and identify one or two ways to address the limitations. Specifically include in your discussion the effect, if any, of the global nature of Pilot Shop’s business.
Step-by-step explanation:
1. The second regression should be adopted for forecasting because the R² is higher in this regression and the standard error is also smaller. the t value is also better in this regression compared to the first
2. Using regression 2, the estimated shipping cost is to be calculated here.
= 642.9 + 3.92NR
NR = 600
642.9 + 3.92X600
= 642.9 + 2352
= $2994.9
This is the estimated shipping cost.
3. The limitations could be due to error in data, the data could be unreliable because of the presence of outliers. Pilot shop is a global business so there is another factor to adds to the limitations, as this costs of buying and shipping are affected by fluctuations in exchange rate and variations in the global market.

What is the equation of a circle with a center at (−3, 2) and radius 16?
Answer:
(x+3)^2 + (y+2)^2 = 16
Step-by-step explanation:
hi!
so the equation of a circle with the center (h,k) and a radius r is:
(x-h)^2+(y+k)^2 = r^2
- h is the x value
- k is the y value
- r is the radius
so using your information you can plug in the given values into the "blanket" formula
which would result in:
(x--3)^2 + (y+2)^2 = 16^2 --> since there is a double negative, you can change that to a positive :)
this means that your equation is:
[tex](x+3)^{2} + (y+2)^{2} = 16^2[/tex]
and you can even simplify 16^2 = 256
end formula!
[tex](x+3)^{2} +(y+2)^{2} = 256[/tex]

Step-by-step explanation:
Sasha is the manager at a factory.
Last weekend 15 employees assembled 390 identical wardrobes.
Sasha wants 1200 of these wardrobes to be assembled next weekend.
How many employees does Sasha need next weekend?
You must show your working.
The number of employees Sasha would need next weekend are = 46
Calculation of total employeesFor a weekend, 15 employees = 390 wardrobes
The number of wardrobes to be assembled next weekend= 1200
If 390 wardrobes = 15 employees
1200 wardrobes = X employees
Make x the subject of formula,
X = 1200 × 15/390
X = 18000/390
X = 46
Therefore, the number of employees Sasha would need next weekend are = 46

Dimple volunteered 32 hours last month at a local animal shelter. This is 20% of the total hours that she has volunteered this year. How many hours did she volunteer this year?
If she was to volunteer 32 hours and it is worth 20%, then that means 32 hours is 1/5 of her yearly hours. If you were to multiply her volunteer hours by five, then you are getting the year number of hours she has volunteered.
32 x 5 = 160
So, she volunteers 160 hours this year.

two numbers are not in the domain of fºg?
Separate your answers with a comma.
Enter the correct answer.
Answer:
5,0
Step-by-step explanation:
f o g is a composite function, y values of g passed as x values into f.
f o g = 1/(x^2 - 5x)
in this case, the only way for the function to be undefined is when
x^2 -5x = 0
x(x - 5) = 0
x = 0 or x = 5
