According to a study by de Anna students, the height for Asian adult males is normally distributed with an average of 66 inches
Maslowich
A. X ~ N(66, 6.25)

b.z_{1} =\frac{65-66}{2.5}=-0.4
z_{2} =\frac{69-66}{2.5}=1.2
Using a standard normal probability table to find probability values for the z-scores, we get:
P(65 < X < 69) = 0.1554 + 0.3849 = 0.5403

c. z= 0.524 and -0.524
0.524=\frac{X-66}{2.5}
1.31 = X - 66
X = 67.31
When z = -0.524, X = 64.69.
P(64.69 < X < 67.31) = 0.4

3/4 of a number minus -16 equals 28. What is the number ?
Zigmanuir [339]

Answer:

The number is 16

Step-by-step explanation:

3/4 n- (-16) = 28

3/4 n + 16 = 28

Subtract 16 from each side

3/4 n +16-16 = 28-16

3/4 n =12

Multiply by 4/3 to isolate n

4/3 * 3/4 n = 12 * 4/3

n = 16
