Problem 9: Seventy percent of adults ages 50 and older want to reach their 100th birthday. You randomly select five adults ages 50 and older and ask them whether they want to reach their 100th birthday. The
random variable represents the number of adults ages 50 and older who want to reach their 100th birthday.
Graph the binomial distribution using a histogram and describe its shape i. e. find the P(X = x) for each of
the X)

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

step-by-step explanation:

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
