Find the mean absolute deviation for the set {-32, 9, 11, 12} A) 0
B) 8
C) 16
D) 32

A

Step-by-step explanation:

{-32, 9, 11, 12}

first, find the mean (Find the sum of the data values, and divide the sum by the number of data values )

(-32) + 9 + 11 + 12 = 0

0/0 = 0

then, find the absolute value of the difference between each data value and the mean: |data value – mean|.

-32 - 0= -32

9 -0 = 9

11 -0 = 11

12 -0 = 0

finally, find the sum of the absolute values of the differences. Divide the sum of the absolute values of the differences by the number of data values.

0 - 0 / 4 = 0

answer is 0 (A)

600,000,000,000, or 6e14

step-by-step explanation:

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
