In the data set below, what is the mean absolute deviation? 3,9,4,4,9,1
If the answer is a decimal, round it to the nearest tenth.

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

i believe it’s 165 because if u add 137 and 58 u get 195 and then subtract that from 360 and there’s ur answer
