First find the mean (sum divided by number of values)
4+5+8+10+15=42
42/5=8.4
Then find the difference between each of the numbers and the mean.
4.4, 3.4, 0.4, 1.6, 6.6
Then find the mean of those values.
4.4+3.4+0.4+1.6+6.6=16.4
16.4/5=3.28
Final answer: 3.28
Answer:
x = 4
Step-by-step explanation:
Given
= 
( cross- multiply )
3x = 12 ( divide both sides by 3 )
x = 4
Answer:
=85
Step-by-step explanation:
I'm pretty sure I'm correct
I switched the x and y so it’s easier to see. The answer is (x-1)/(23).
the difference of 5 times the cube of x cubed and the quotient of 4 times x and 3
5*x^3 - (4x/3)
