8*{[7+4)*2-[(11-7)*4]}
Rzqust [24]

Answer:

(8 (-1))

Step-by-step explanation:

Simplify the following:

8 (7 + 4×2 - 4 (11 - 7))

11 - 7 = 4:

8 (7 + 4×2 - 44)

4×2 = 8:

8 (7 + 8 - 4×4)

-4×4 = -16:

8 (7 + 8 + -16)

7 + 8 = 15:

8 (15 - 16)

15 - 16 = -(16 - 15):

8 (-(16 - 15))

| 1 | 6

- | 1 | 5

| 0 | 1:

8 (-1)

8 (-1) = (8 (-1)):

Answer: (8 (-1))

The heights of North American women are nor-mally distributed with a mean of 64 inches and a standard deviation of 2 inches. a.
serious [3.7K]

Answer:

0.1587

Step-by-step explanation:

Given the following :

Mean (m) of distribution = 64 inches

Standard deviation (sd) of distribution = 2 inches

Probability that a randomly selected woman is taller than 66 inches

For a normal distribution :

Z - score = (x - mean) / standard deviation

Where x = 66

P(X > 66) = P( Z > (66 - 64) / 2)

P(X > 66) = P(Z > (2 /2)

P(X > 66) = P(Z > 1)

P(Z > 1) = 1 - P(Z ≤ 1)

P(Z ≤ 1) = 0.8413 ( from z distribution table)

1 - P(Z ≤ 1) = 1 - 0.8413

= 0.1587
