The list below shows the prices of t-shirts at a clothing store. {8, 10, 10, 12, 15, 15, 18} which statement best describes the mean of this set? the difference between the least and greatest prices the sum of the prices the quotient of the difference between the least and greatest prices divided by 7 the sum of the prices divided by 7

(D) The sum of the prices divided by 7

Step-by-step explanation:

It is given that the list below shows the prices of T-shirts at a clothing store that is:

{8, 10, 10, 12, 15, 15, 18}.

Now, Mean of the given data set is given as:

Therefore, the mean is given as the sum of the prices divided by 7 that is 12.57.

Hence, option D is correct.

i dont know sorry

step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
