Ollow the steps below to find the mean for the set of data. Use the work shown to help you.

Data set: 6, 5, 8, 5, 9, 6, 7, 5, 12

First add the values.

6 + 5 + 8 + 5 + 9 + 6 + 7 + 5 + 12 = 63

Then divide by the number of values.

There are 9 values.

What is the mean of the data set?
5
6
7
8

if im undersanding the question correctly, its organized from 10

step-by-step explanation:

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
