<h3>Bump It Up charges more per bumper sticker than You Name It charges.</h3><h3>The initial fee charged by You Name It is greater than the initial fee charged by Bump It Up.</h3>Step-by-step explanation:
The second and last statements are true about the function shown in the image.
The money charged per sticker refers to the ratio between both variables. So, the ratio for You Name It is:
The ratio for Bump It Up is:
As you can see Bump It Up has a higher ratio, that is, it charges 20 bucks more per sticker than You Name It.
The benefit of picking Bump It Up is actually if Armand needs less than 500 stickers, because after 500 it's better to use You Name It.
On the other hand, the graph shows that the initial point of You Name It is 200, and the initial point of Bump It Up is 100. So, the initial fee charges by You Name It is higher than the initial fee charges by Bump It Up.
Therefore, the right answers are the second and the last statements.

Answer:
a.) .95
b.) The expected number of baskets is 10.50.
c.) 1.7748
Step-by-step explanation:
a.) This is a binomial distribution as there are two possibilities: makes a free throw or doesn't. This means that you can use the binomial function on a calculator to figure out the answer. Use the binomial CDF function on a calculator and the number of trials=15, probability of success=.7, lower bound=0, upper bound=7. Once you have evaluated the answer, .0500, it will need to be subtracted from1, as you want everything not included in this section. The answer to part a is thus 1-.0500=.95.
b.) The expected value is calculated by taking the total number of shots and multiplying it by the probability of making the shot: 15×.7=10.5 shots.
c.) The standard deviation of a binomial distribution can be calculated by the formula . Plugging in the numbers you get
=1.7748.
