If x is 12 units away from 20 it is either 20-12 or 20+12 so the two possibilities would be 8 or 32
Hope this helps!!
Answer:
Step-by-step explanation:
Given that a survey found that women's heights are normally distributed with mean 63.4 in and standard deviation 2.2 in.
Let X be the random variable representing women heights.
P(58<X<80)
Z for 58 = -2.454
Z for 80 = 7.545
P(-2.454<Z<7.545) = 0.4945+0.5=0.9945
If you take 3 inches off each end, that means you will be taking 6 inches off. If you take 6 inches away from 7 1/4 yards ,(7 yards, 9 inches,) you get 7 1/12 yards (7 yards, 3 inches).
(7 1/12) / 5 = 1.426repeating
So each piece of rope will be (Approximately) 1.4 or 1 2/5 yards.
(I think.)
