Answer:
a) 0.64
b) -1.13
Step-by-step explanation:
We are given the following information in the question:
Women:
Mean, μ = 64.2 inches
Standard Deviation, σ = 2.8 inches
We are given that the distribution of heights of women is a bell shaped distribution that is a normal distribution.
Men:
Mean, μ = 69.4 inches
Standard Deviation, σ = 3.0 inches
We are given that the distribution of heights of men is a bell shaped distribution that is a normal distribution.
Formula:
5.5 feet = 66 inches
a) z‑score for a woman 5.5 feet tall
b) z‑score for a man 5.5 feet tall
I thought this was a vector problem but no, this is quite easy!
You are correct; this draws the letter W.
The so-called "vector" means for you to translate the same distance. That vector goes left 3 and up 4 -- translate your point at Step 2 left 3 units and up 4 units. There you go!

Answer:
Step-by-step explanation:
19.
The numbers are m and n
Sum of m and n = m + n
Sum is multiplied by 91 = 91 x ( m + n )
20.
Let the number be = m
Six subtracted from the number = m - 6
41 times the difference = 41 x ( m - 6)
21.
Let the number be = r
Difference between 83 and 10 = 83 - 10 = 73
22.
Total of p and 23 = p + 12
23.
The product of c and 3 = 3c
Sum of 9 and 12 = 21
Product is more than Sum = 3c + 21
24.
Sum of y and 10 = y + 10
Number x decreased by 5 = x - 5
