Answer:
0.15%
Step-by-step explanation:
The mean is μ = 3500 and the standard deviation is σ = 500.
2500 is 2 standard deviations below the mean, which we can calculate by finding the z-score.
z = (x − μ) / σ
z = (2500 − 3500) / 500
z = -2
According to the empirical rule, 99.7% of a normal distribution is between -2 and +2 standard deviations. Which means 0.3% is outside of that. Since a normal distribution is symmetrical, half of that, or 0.15%, is less than 2 standard deviations.

Answer: A constant
Step-by-step explanation:
Answer:
Y1 intercept = 2
(0,2) (3,-7)
m= (-7 - 2) / (3-0) =-9/3 = - 3
Then y = - 3x + 2
Y2 intercept = - 8
(0,-8) (3,-7)
m = (-7 - - 8) / (3-0) = 1/3
Then y= (1/3)x-8
