A basketball player makes 70% of the free throws he shoots. Suppose that he tries 15 free throws. a. What is the probability that he will make more than 7 throws?
• enter your answer as a percent (56) or as a real-value (0.05)
. you enter your answer as a percent, you must use a-sign in your answer
• your answer must be accurate to the nearest whole percent.
b. How many baskets can the player expect to make it he takes 15 shots? .
. Your answers must be accurate to the nearest hundreth.
c. What is the standard deviation of the number of successful free throws out of 15 total?

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.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

days of the week

step-by-step explanation:

javier earned more money then kyle, so that won't always be a constant term, but the days of the week do not change so that term is always constant.
