4. Calculate the mean of the data set {22, 34, 37, 23, 45, 21, 29, 37}. Round to the nearest tenth.
Simora [160]

Answer:

31.0

Step-by-step explanation:

The mean of a given set of data is the ratio of the sum of the data to the number of units that make up the data set. It is also called the average of the data set.

Given the data set {22, 34, 37, 23, 45, 21, 29, 37}. There are 8 numbers in the set. The total of these numbers

= 22 + 34 + 37 + 23 + 45 + 21 + 29 + 37

= 248

The mean = 248/8

= 31

Solve the equation.
nadya68 [22]

Answer:

A. No solution

Step-by-step explanation:

The given equation is 4(2 x + 9) = 4(2 x +6)

We divide through by 4 to get:

2 x + 9 = 2 x +6

We now group similar terms to obtain:

2x - 2x = 6 - 9

0 =  - 3

This final statement is false.

Therefore the given equation has no solution.
