It is a function because each x values have ONE y value
Order them from smallest to largest:
21, 24, 25, 26, 26, 31
mean: 25.5
add all the numbers up and divide them by 6.
median: 25.5
the number in between 25 & 26.
mode: 26
there are two 26’s in the pattern.
range: 21-31
The equation is:
13.25h = 278.25
Solve for h in this case by dividing 278.25 by the 13.25 dollars per hour.
The answer will be:
21 hours
Answer: z= -5
Step by Step:
-4(2z+6)-12=4
-8z-36=4
-8z-4+36
-8z=40
z=-5
