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.
The equation in the given standard form is

X=8/9. There's your answer.
Answer= 3
trust me it is 3
let me explain
y=mx +b
=(-1)x + (3)
= -1x + 3
y= -x+3
therefore the answer is = 3
