Points B, D, and F are midpoints of the sides of ACE. EC = 32 and BF = 2x - 10. Find the value of x.

Svetlanka [38]

Answer:

Step-by-step explanation:

Remark

This only works if B is between AC and F is between AE

Givens

CE = 32

BF = 1/2 CE Properties of midpoints. BF is parallel to and 1/2 of CE

BF = 1/2 * 32

BF = 16

Equation

2x - 10 = 16 Add 10 to both sides

2x - 10 + 10 = 16 + 10 Combine

2x = 26 Divide by 2

2x/2 = 26/2 Do the division

x = 13

A researcher reports that the probability of a college student living on campus is p = .38. If a small local college has 2,000 s

Olin [163]

Answer:

The standard deviation of the distribution is 21.7 students.

Step-by-step explanation:

We are given the following in the question:

We treat college student living on campus as a success.

P(college student living on campus) = 0.38

Then the number of students follows a binomial distribution.

Sample size, n = 2000

We have to evaluate the standard deviation of the distribution.

Formula:

$\sigma = \sqrt{np(1-p)}$

Putting values, we get,

$\sigma = \sqrt{2000(0.38)(1-0.38)} = 21.7$

Thus, the standard deviation of the distribution is 21.7 students.
