The table shows the price of admission at eight theaters.

theater admission prices ($)

5.00

7.50

8.25

8.00

9.75

10.25

11.00

10.75

find the mean absolute deviation of admission prices. round to the nearest hundredth if necessary.

The mean absolute deviation of the data set is 8.8125

Step-by-step explanation:

First find the mean of the data by adding all data points together then divide by the number of data points.  5.00+7.50+8.25+8.00+9.75+10.25+11.00+10.75=70.5

70.5÷8=8.8125

Secondly, find the absolute value of the mean. In short, the absolute value of any number is the same number but positive.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
