Part 1 out of 2 Find the mean and the median of this data set: 10, 7, 6, 4, 42, 7, 5, 3

Mean = 10.5

Median = 6.5

Step-by-step explanation:

10, 7, 6, 4, 42, 7, 5, 3

3 4 5 6 7 7 10 42

Median = (6 + 7)/2 = 6.5

Mean: (3 + 4 + 5 + 6 + 7 + 7 + 10 + 42) ÷ 8

= 84/8 = 10.5

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

x-150=475   x=625

step-by-step explanation:

if the bike after the sale ($150) is $475 then just simply add 150 to 475.
