In recent studies, each of the following variable pairs show a high correlation. which appear to share a cause-effect relationship? check all that apply
a. basketball games played and total points scored
b. hours of television watched per day and shoe size
c. quantity of food eaten and weigth gained
d. score on a math test and performance of japan`s stock market

The following variable pair that shows a high correlation is:

Option:C.  quantity of food eaten and weight gained.

Step-by-step explanation:

A)

Basketball games played and total points scored.

Let 5 basketball games were played and in the first game 12 points were scored.

While in the other 4 games 0 points were scored.

so as the total score remains constant hence the correlation is not high.

( Since a correlation is high if it is increasing).

B)

Hours of television watched per day and shoe size.

There is no relation between the two variables.

C)

Quantity of food eaten and weight gained.

This represents a high correlation because if we will consume good food then the weight will definitely increase.

D)

score on a math test and performance of japan`s stock market.

Again there is no correlation between the two variables as the math test score and stock market rate are nowhere related.

Hence, the correct answer is:

Option: C.

what are ur choices?

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.
