Answer:
x = 7/3
Step-by-step explanation:
3x + 2 = 2x + 13/3
3x - 2x = 13/3 - 2
x = 13/3 - 2/1
x = 13/3 - 6/3
x = 7/3

Without words you might not understand what is being asked to do.
Well, it has notation in it so when it is turned into function notation you will know how to reverse it and put it back the same way.
Answer:
81.24%
Step-by-step explanation:
First we solve for the variance
Sample space of
3,5,12,3,2
n = 5
Variance = s²
= (3-5)²+(5-5)²+(12-5)²+(3-5)²+(2-5)²/5-1
= 4+0+49+4+9/4
S² = 66/4
= 16.5
Secondly we find the standard deviation
= √16.5
= 4.062
Coefficient of variation
Cv = sd/mean x 100
= 4.062/5 x 100
= 406.2/5
= 81.24%
