V ≈ 7850

Step-by-step explanation:

V= πr^2h is the formula

so V = 3.14 * 10^2 * 25

V = 3.14 * 2500 = 7850

depending on what decimal you use for pi, your answer will differ

Answer:

B ; C ; D

Step-by-step explanation:

Number of faces on a number cube = 6

Sample space = (1, 2, 3, 4, 5, 6)

P(1 then 0)

P(1) = 1/6 ; P(0) = 0

P(1 then 0) = 1/6 * 0 = 0

P(even number then odd number) :

P(even number) = 3/6 = 1/2

P(odd) = 3/6 = 1/2

P(even number then odd number) = 1/2 * 1/2 = 1/4

P(6 then 2) :

P(6) = 1/6 ; P(2) = 1/6 = 1/2

P(6 then 2) = 1/6 * 1/6 = 1/36

P(even number then 5) :

P(even) = 3/6 = 1/2

P(5) = 1/6

P(even number then 5) = 1/2 * 1/6 = 1/12

P(odd number then 2) :

P(odd) = 3/6 = 1/2

P(2) = 1/6

P(odd number then 2) = 1/2 * 1/6 = 1/12

A true-false quiz with 10questions was given to a statistics class. Following is the probability distribution for the score of a
SSSSS [86.1K]

Using the mean <u>formula and it's interpretation</u>, it is found that:

1. The mean is 7.52.

2. If we were to give this quiz to more and more students, the mean score for these students would approach 7.52.

The mean of a discrete distribution is given by the <u>sum of each outcome divided by it's respective probability</u>.

Hence, in this problem, according to the <u>distribution given</u>, the mean is:

E(X) = 5(0.06) + 6(0.12) + 7(0.33) + 8(0.29) + 9(0.13) + 10(0.07) = 7.52

The mean is 7.52.

The <em>interpretation </em>is that over many trials, the mean would approach 7.52.
