An electric utility company determines the monthly bill by charging 85.4 cents per​ kilowatt-hour (kWh) used plus a base charge of ​$17.55 per month.​ Thus, the monthly charge is given by the function f(W)=0.854W+17.55 ​dollars, where W is the number of​ kilowatt-hours.
a. Find f (6000​) and explain what it means.
b. What is the monthly charge if 9500 kWh are​ used?
a. Select the correct choice below and fill in the answer box to complete your choice.
​(Simplify your answers. Type integers or​ decimals.)
A. f(6000)= nothing.
The charge for 6000 kWh is $nothing.
B. f(6000)= nothing.
The charge for nothing kWh is ​$6000.
b. The monthly charge is ​$nothing if 9500 kWh are used.
​ (Simplify your answer. Type an integer or a​ decimal.)

Step 1
Given that
An electric utility company determines the monthly bill by charging 85.4 cents per​ kilowatt-hour (kWh) used plus a base charge of ​$17.55 per month.​ Thus, the monthly charge is given by the function f(W)=0.854W+17.55 ​dollars, where W is the number of​ kilowatt-hours.
Step 2
To find a. f(6000).
b. What is the monthly charge if 9500 kWh is used.
a. To find: f(6000).
The monthly charge is given by function, f(W)=0.854W+17.55
So to find f(6000) substitute W=6000f(W)=0.854W+17.55,
f(6000)=0.854(6000)+17.55
f(6000)=5141.55
Therefore there is monthly charge of $5141.55 if 6000 kWh is used.
Step 3
b. To find What is the monthly charge if 9500 kWh is used.
Substitute W=9500f(W)=0.854W+17.55,
f(9500)=0.854(9500)+17.55
f(9500)=8130.55
Therefore the monthly charge if 9500 kWh is used is $8130.55.

According to a study by Dr. John McDougall of his live-in weight loss program at St. Helena Hospital, the people who follow his program lose between 6 and 15 pounds a month until they approach trim body weight. Let's suppose that the weight loss is uniformly distributed. We are interested in the weight loss of a randomly selected individual following the program for one month. Give the distribution of X. Enter an exact number as an integer, fraction, or decimal.f(x)= where X.μ=σ=. Find the probability that the individual lost more than 8 pounds in a month.Suppose it is known that the individual lost more than 9 pounds in a month. Find the probability that he lost less than 13 pounds in the month.
