Answer:

3.98 cm, 602.18 cm²

Step-by-step explanation:

Given:

r= 8 cm
V= 800 cm³

To find:

h = ?
S = ?

Solution:

V = πr²h
h = V/πr² = 800/(π8²) = 3.98 cm
S = 2πr (r+h) = 16π(8+3.98) = 602.18 cm²

Jerry has taken a random sample of students and determined the number of electives that each student in his sample took last yea

loris [4]

The sample proportion of the the students that took fewer than the mean number of electives is given by the number of people who took less that the mean number of electives (i.e. 7.63) divided by the total number of students in the sample (i.e. 19). The total number of people who took less than 7.63 electives is 10. Therefore, the required sample proportion is 10 / 19.
