Answer:

a. B

b. 4

c. BD

Step-by-step explanation:

a. Point A is at -7; point D is at +1. The distance between these points is ...

1 -(-7) = 8

The midpoint will be 8/2 = 4 units from either end so will be at ...

A +4 = -7 +4 = -3

D -4 = 1 -4 = -3

The point located at -3 is point B, the midpoint of AD.

b. Having done the above calculations, we know that segment AB is 4 units long.

c. We also know that segment BD is 4 units long. That is because the midpoint divides a segment into two equal parts.

A study shows that 20% of college students pray daily in their own religious beliefs. In a group of 300 college students, find t

Answer:

0.2805

Step-by-step explanation:

Given that p = 20% = 0.2, n = 300.

The mean (μ) = np = 0.2 * 300 = 60

The standard deviation (σ) = $\sqrt{np(1-p)}=\sqrt{300*0.2(1-0.2)}=6.93$

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

$z=\frac{x-\mu}{\sigma }$

For x = 57:

$z=\frac{57-60}{6.93 } =-0.43$

For x = 62:

$z=\frac{62-60}{6.93 } =0.29$

From the normal distribution table, P(57 < x < 62) = P(-0.43 < z < 0.29) = P(z < 0.29) - P(z < -0.43) = 0.6141 - 0.3336 = 0.2805
