Answer:

mean =33

mad  = 6

Step-by-step explanation:

First we need to find the mean

Add up all the numbers and divide by the number of numbers)

(29+ 20+ 36+ 44+ 30+ 32+ 40)/7

231/ 7

33

To find the mean absolute deviation

take the positive difference  for each term and then divide by the number of terms

((33-29)+ (33-20)+ (36-33)+ (44-33)+ (33-30)+ (33-32)+ (40-33))/7

42/7

6

PLEASEEEEE HELPPPP MEEEEEEE BRAINLIEST TO THE FIRST ANSWER AND 30 POINTS
icang [17]

Answer:

CD ≠ EF

Step-by-step explanation:

Using the distance formula

d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

with (x₁, y₁ ) = C(- 2, 5) and (x₂, y₂ ) = D(- 1, 1)

CD = \sqrt{(-1+2)^2+(1-5)^2}

      = \sqrt{1^2+(-4)^2}

      = \sqrt{1+16} = \sqrt{17}

Repeat using (x₁, y₁ ) = E(- 4, - 3) and (x₂, y₂ ) = F(- 1, - 1)

EF = \sqrt{(- 1+4)^2+(-1+3)^2}

     = \sqrt{3^2+2^2}

     = \sqrt{9+4} = \sqrt{13}

Since \sqrt{17} ≈ \sqrt{13} , then CD and EF are not congruent
