Assuming that Anita needs hollow right circular cones, we are solving for its lateral surface area, which is given by the formula πr√(h²+r²), where r is the radius and h is the height.
r = 6 ft / 2 = 3 ft
Solving for the lateral surface area of one cone:
LSA = (3.14) (3) [√(12²+3²)] = 116.52 sq ft.
Since she needs 10 cones:
10 * 116.52 sq. ft = 1,165.2 sq ft.
She will need 1,165.2 sq ft of material.
Answer:19 students
Step-by-step explanation:
First you would add together all the students that you know take a math class. So you would add 14+20+7 to get 41 students. So now you know that that many students take a math class. So you would do 60-41 because 60 is your overall number of students. After you subtract them you should get 19 which is your answer-19 students don’t take either of the subjects
Answer:
B
Step-by-step explanation:
Initial mean = 156, Changed mean = 163.92
So, mean increases. Only condition that satisfies this is B.
Answer:
(I don't know how to do part B sorry :(. But I can help you with part A)
Part A: The mean of the data is 5
Step-by-step explanation:
To find the mean, you add up all the numbers, then divide the numbers depending on how many numbers there are. In this case:
4 + 3 + 4 + 5 + 6 + 6 + 8 + 4 = 40
------------------------------------------------------------------------------------------------------------
Next we divide:
40 ÷ 8 = 5

Have a good day :)
