Answer:
x = X + 33 (I am guessing "x" and "X" are not the same. "x" is a variable and "X" is a constant.)
Step-by-step explanation:
31 - X + (2x+1) = x - 1
or, 2x+1 = x - 1 - 31 + X
or, 2x - x = -1 -31 + X -1
or, x = -2 -31 + X
or, x = X - 33
Step-by-step explanation:
3 + 4 + 5 + 6 + 6 + 7 + 8 + 8 + 9 + 9 / total of numbers or 10 = 65 ÷ 10 = 6.5 This is the mean.
3 - 6.5 = 3.5
4 - 6.5 = 2.5
5 - 6.5 = 1.5
6 - 6.5 = 0.5
6 - 6.5 = 0.5
7 - 6.5 = 0.5
8 - 0.5 = 7.5
8 - 0.5 = 7.5
9 - 0.5 = 8.5
9 - 0.5 = 8.5
MAD = 1.7
Answer:
Not a function.
Step-by-step explanation:
There must only be one output per input but here we see the input 18 has two outputs ; 3 and 15 therefore this is not a function.
