The probability that Rahul succeeds at any given free-throw is 70%. He was curious how many free-throws he can expect to succeed in a sample of 15 free-throws. He simulated 30 samples of 15 free-throws where each free-throw had a 0.7 probability of being successful. Rahul counted how many free-throws were successful in each simulated sample. Here are his results: Use his results to estimate the probability that he succeeds at 11 or fewer free-throws in a sample of 15 free-throws.

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.

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
