Suppose 60% of all students at a college were receiving a Pell Grant. If you took a random sample of 20 of these college students, the probability that at least 15 of them received a Pell Grant is .125. True or False?

answer: a.   one is a factor of every whole number since every number is divisible by itself.

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

(picture explains)

b, i believe, but not sure.

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.
