The weight of football players is normally distributed with a mean of 200 pounds and a standard deviation of 25 pounds. the prob
ability of a player weighing less than 250 pounds is closest to:
1 answer:
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: y=2x+14
Explanation:
Y=mx+b
Y= 2x-4
M=2
Y= 2x+b
2 = (2 x -6) + b
2=-12+b
12+2=12+b
-12
14=0+b
14=b
Y=2x+14
Answer:
the answer is s=5/4 minus 1/16
