What is the mean absolute deviation of the data set?

B

Step-by-step explanation:

x=6,8 ,15, 15, 16, ⇒ these are the set of values given

N=5 ⇒this represent the number of set of values given

Find the mean of set of values

Mean=sum of set of values/N

mean= 6+8+15+15+16=60/5 =12

find mean absolute

First find ║x-mean║⇒every set of data subtract the mean value

║x-mean║= 6, 4,3,3,4 ⇒this represents the deviations

sum of ║x-mean║=6+4+3+3+4=20

Finding mean absolute deviation

mean absolute deviation = sum of ║x-mean║÷ N where N is number of data set

N=5

20/5 =4

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
