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

Answer:

If there are 2 quarters for every 3 nickels,

then there are $45*\frac{2}{3} =30$ quarters.

If there are 2 dimes for every quarter,

then there are $30*2=60$ dimes.

If the number of pennies and nickels together are equal to the number of dimes, then there are $60-45=15$ pennies.
