It’s nonlinear because you can’t put x by itself
Step-by-step explanation:
The probability that a normally distributed data with a mean of μ and a standard deviation of σ is less than a value x is given by:

Given that μ = 16.5 and σ = 0.804984 and that the probability that the <span>mean oil-change time being at or below the
sample mean for which there is an area of 0.10 to the left under the
normal curve, then:

Following the 30% rule of thumb, Sally should only spend a maximum of $900 on her rent
<h3>Numbers and percentage</h3>
Given Data
- Monthly Salary = $3000
