Answer:

Mean Deviation = 5

Step-by-step explanation:

The numbers are given as;

8, 12, 12, 25, 10, 14, 4, 3, 22, 10

Mean = Sum of numbers / Population = 120 / 10

Mean = 12

mean deviation involves finding the sum of the absolute values of the differences between the individual elements and the mean. Then divding by the population.

Mean Deviation = |(8 - 12) + (12 - 12) + ( 12  - 12) + (25- 12) + (10- 12) + 14- 12) + (4- 12) + (3 - 12) + (22- 12) + (10- 12)

| / 10

Mean Absolute Deviation = 5

neonofarm [45]

Answer:

4 umbrellas

Step-by-step explanation:

Number of Umbrellas              Total Money

                1                                            $12                

                2                                           $24

                3                                           $36

                4                                           $48

She can't go over $48 because $48 + $12 is $60, which is more than she has ($54). So the max amount of umbrellas she can buy is 4.
