If one woman is selected find the probability that her height is less than 65 inch with a mean of 64.4 and standard deviations o
Debora [2.8K]

The probability of one woman to have height less than 64.4 in is 0.6293

<u>Explanation:</u>

Given:

Mean, μ = 64.4

Standard deviation, δ = 1.8

Probability that the height of the woman is less than 65 inch = ?

So,

P(x < 65) = 65 - μ / δ

              =\frac{65 - 64.4}{1.8}\\ \\= 0.33

P (x < 65) = P( z < 0.33)

Finding the probability value from the z table we get:

P( z < 0.33) = 0.6293

Therefore, the probability of one woman to have height less than 64.4 in is 0.6293

How do you answer this question with workings
Murrr4er [49]

Answer:

$32.80

Step-by-step explanation:

Let f be the cost of a file, then a storybook costs 3f ( 3 times as much )

Then the difference in cost is

3f - f = 16.40, that is

2f = 16.40 ( divide both sides by 2 )

f = 8.20

The cost of a file is $8.20 and the cost of a storybook is 3 × $8.20 = $24.60

The total cost of the 2 items = $8.20 + $24.60 = $32.80
