The dot plot below shows the number of wings contestants in a wing-eating contest ate.

what is the mean absolute deviation of the data set shown?
a. 18
b. 18.1
c. 3
d. 1.52

the answer is D. 1.52

Step-by-step explanation:

you want to add all the numbers then divide by 10

15 + 15 + 17 + 18 + 18 + 18 + 19 + 20 + 20 + 21

                             10

then you find the difference between the mean and data point

Data point = 15    15    17    18     18     18     19    20    20     21

Mean Diff  = 3.1   3.1     1.1    0.1   0.1   0.1    .9      1.9    1.9    2.9

then add the differences

3.1 + 3.1 + 1.1  + 0.1 + 0.1  +  0.1 + .9 + 1.9 + 1.9  + 2.9 and divide by 10

                                    10

absolute deviation is 1.52 wings.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!
