The graph shows the data for the time it takes Jerome to bike to school, based on his average biking speed for that trip. Which sentence describes the association? A. As the average speed increases, so does the time he takes to get to school. B. As the average speed increases, the time he takes to get to school decreases.
C. The speed he bikes at does not affect the time it takes him to get to school. D. The speed he bikes at affects the time it take him to get to school, but it is unclear if the time increases or decreases.

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

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.
