Answer:
2 < x <7 I got the same question has you
Step-by-step explanation:
.....
Given :
The equation below can be used to determine I (simple interest) on a loan as follows :
...(1)
P is principal, r the rate of the loan, t is the length of the loan in years.
We need to find the equation to solve in terms of r. We can find the value of P.
Dividing both sides of equation (1) by rt. So,

So, P can be solved as :
.
If Eric earns $56 or more means
t is greater or equal to 56
Probability is like 50% or 1/2 like If you flip a coin the probability is 1/2,
If 62.5% take more than 21 minutes
<span>37.5% take less than 21 minutes </span>
<span>convert .375 to a zscore using the normal distribution chart in your book </span>
<span>P(.375) = z -0.318639364 </span>
<span>(21 - x) / 6.2 = -0.318639364 </span>
<span>(21 - x) = -1.9755640568 </span>
<span>22.9755640568 = x </span>
<span>mean commute is 22.98 minutes</span>
