And replacing we got:

Step-by-step explanation:
We can define the random variable X as the thickness of a protective coating applied to a conductor designed to work in corrosive conditions. And the distribution for X is given by:

And we want to find this probability:

And in order to find this probability we can use the cumulative distribution function given by:

And if we use this formula for the probability desired we have:

And replacing we got:

Answer:
Is it The numbers on the ruler?
Step-by-step explanation:
Answer:
FV= $2,041.29
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $1,500
Number of periods (n)= 7 years
Interest rate (i)= 4.5% = 0.045
<u>To calculate the future value, we need to use the following formula:</u>
FV= PV*(1+i)^n
FV= 1,500*(1.045^7)
FV= $2,041.29
The answer is subtraction
