Alright, so the book is on sale for 4 dollars right? So do 32/4 and that will be 8, so the percent is 8%
Given:
μ = 200 lb, the mean
σ = 25, the standard deviation
For the random variable x = 250 lb, the z-score is
z = (x-μ)/σ =(250 - 200)/25 = 2
From standard tables for the normal distribution, obtain
P(x < 250) = 0.977
Answer: 0.977
Answer:
The inequality would be true
Step-by-step explanation:
4(c+2) < 4c + 10
Distribute the 4 on the left
4c + 8 < 4c + 10
Subtract 4c from both sides
8 < 10
8 < 10 is true
Answer:x=(y-25)/15
