A company is going to make an oil container in the shape of a cylinder. As shown below, the container will have a height of 5m and a radius of 3m. The container will be made from steel (including its top and bottom). If the steel costs $24 for each square meter, how much will the steel cost in total? If necessary, refer to the list of geometry formulas. For your calculations, do not round any intermediate steps, and use the π button on the ALEKS calculator. Round your answer to the nearest cent.
Answers
Answer:
1,172.3 cm³
Step-by-step explanation:
Find the volume of one rod, then divide the total volume of steel used by the volume of one rod. The volume of one rod is
V = (πd²/4)h
d = 4 cm
h = 20 cm
Plugin the numbers and get V in cm³, then divide the given total volume of 28,134.4 cm³ by V. If the result is not an integer, then round down.
Add
20 + 4 = 24
Then
28,134.4 ÷ 24 = 1172.26
Rounded to the nearest 0.1 or the Tenths Place = 1,172.3
Therefore, 1,172.3 rods will be made per hour.

A food truck sells burgers and hot dogs. During lunch, it sold 88 items for a total of $331. If burgers cost $4.50 and hotdogs cost $3.25, how many of each item were sold?
Answers
Number of hot dogs = d = 52
We know that b + d = 88 (they sold 88 items)
And 4.5b + 3.25d = 331 (price • number = money made)
So we will solve the first equation for b in terms of d, then substitute that in the second equation to sell for a numerical value of d.
b + d = 88
b = 88-d
4.5(88-d) + 3.25d = 331
396 - 4.5d + 3.25d = 331
-1.25d = -65 (divide both sides by -1.25)
d = 52
Now plug that into the first equation to get a numerical value for b.
b = 88 - d
b = 88 - 52
b = 36
Checking the math:
4.5(36) + 3.25(52) = 162 + 169 = 331

A regression equation has been developed in order to help predict the amount of sales made in a clothing store each day (y) based on the number of square feet covered by the store's floor space (x). A sample of 100 similar clothing stores is collected, with floor spaces ranging from 100 square feet to 300 square feet. For each store, the floor space (in square feet) and the amount of sales made that day (in dollars) are recorded. The following regression equation is calculated:
y^ = 2,050 + 54x
Select whether or not each of the following conclusions are correct from the regression analysis: Fill in blank with ither response :Correct or Not correct
a. If the floor space of a store were to increase by one square foot, the predicted increase in sales would be $2,050. ______________
b. If a store has a floor space of 75 square feet, the predicted sales in a day is $6,100. ____________

Anna has n number of nickels. She has less than 45 cents. Which inequality could be used to the find the value of n?
A 0.05n < 0.45
B 0.05n > 0.45
C 0.05n < 0.45
D 0.05n > 0.45
Answers
Answer:
The correct answer is A or C 0.05n < 0.45
Step-by-step explanation:
Nickels cost $0.05 and n is the number of nickels, so you multiply the two to get 0.05n. Since this value is less than $0.45, we put a less than sign.

94 hours to 8 days
Answers
Answer:
11.75:1
Step-by-step explanation:
alrighty right, more unit rates, so we have to get that 8 down to 1. How are we gonna do that? By dividing it by 8. And if we divide one side by 8, we also have to divide the other side:
8 ÷ 8 = 1
94 ÷ 8 = 11.75
So 94 hours to 8 days in lowest terms is 11.75 hours to 1 day
Seth's homework assignment is to write factor pairs that contain only composite
numbers. Seth wrote four factor pairs for the number 132, as shown below.
6 x 22
11 x 12
3 x 44
2 x 66
Which of Seth's factor pairs contains only composite numbers?
F 6 x 22
G 11 x 12
H 3 x 44
J 2 x 66
Answers
Answer:
F. 6 x 22
Step-by-step explanation:
6 has more than two factors ( 1, 6, 2, 3), which makes it a composite number.22 has more than two factors (1, 22, 2, 11), which makes it a composite number.Therefore, F is the correct answer.The Seth's factor pairs that contains only composite numbers are
6 × 22.
Composite numbers are numbers with more than 2 factors.
They are natural numbers or positive integers with more than 2 factors. Examples are 15, 10, 20 etc...
The Seth's factor pairs that contains only composite numbers are
6 × 22.
The factors of 6 are 1, 2, 3 and 6
The factors of 22 are 1, 2, 11 and 22.
They both have more than 2 factors.

In testing hypotheses, which of the following would be strong evidence against the null hypothesis?
a. obtaining data with a low test statistic.
b. using a small level of significance.
c. using a large level of significance.
d. obtaining data with a large p-value.
e. obtaining data with a small p-value.
Answers
Answer:
e. obtaining data with a small p-value.
Step-by-step explanation:
In the null hypothesis, we test if the mean respects certain condition, and on the alternate hypothesis, we test the opposite of the null hypothesis.
The decision depends on the pvalue:
If the pvalue is smaller than the level of significance, that is, the pvalue has small values, the null hypothesis is rejected, that is, it is strong evidence against the null hypothesis. Large pvalues do not give evidence against the null hypothesis.
So the correct answer is given by option e.

A sign on a barrel of nuts in a supermarket says that it contains 30% cashews, 30% hazelnuts, and 40% peanuts by weight. You mix up the nuts and scoop out 18 pounds. When you weigh the nuts, you find that you have 5 pounds of cashews, 4 pounds of hazelnuts, and 9 pounds of peanuts. Is there evidence to doubt the supermarket's claim
Answers
Answer:
The calculated χ² = 0.842 does not fall in the critical region χ² ≥ 5.99 so we accept the null hypothesis that all the proportions are equal and there is not enough evidence to doubt the supermarket's claim.
Step-by-step explanation:
1) We set up our null and alternative hypothesis as
H0: p1= 5/18, p2= 4/18, p3= 9/18
against the claim
Ha: p1≠ 5, p2≠ 4, p3≠ 9
2) the significance level alpha is set at 0.05
3) the test statistic under H0 is
χ²= ∑ (O - E)²/ E where O is the observed and E is the expected frequency
which has an approximate chi square distribution with 2 d.f
4) Computations:
Observed Expected χ²= ∑ (O - E)²/ E
5 5.4 0.0296
4 5.4 0.3629
9 7.2 0.45
∑ 0.842
5) The critical region is χ² ≥ χ² (0.05)2 = 5.99
6) Conclusion:
The calculated χ² = 0.842 does not fall in the critical region χ² ≥ 5.99 so we accept the null hypothesis that all the proportions are equal and there is not enough evidence to doubt the supermarket's claim.

Step-by-step explanation:
Answer:
75%
Step-by-step explanation:
In a box-and-whisker plot, the whiskers show the minimum and maximum while the edges of the box show the first and third quartiles. The line in the box shows the median.
Quartile means a quarter of the data.
We're trying to find out what percentage of the students scored between 70 and 100.
70 is right on the 1st quartile mark, while 100 is on the maximum mark.
This means that a quarter of students got lower than 70, and nobody scored over 100 (because it's a test and it's calculated in percentage).
If a quarter of students got lower than 70, that means three-quarters of students got 70 or higher. And since the maximum is 100, and that is also what we're trying to find, the answer is 3/4 of all students.
3/4 = 75%
Hence, the answer is 75%.
