answers

A.19°C


B.29°C


C.45°C


D.116°C

Answer 1

B is the right answer because mean is the sum of all numbers divided by the total number of value. in this case it’s (19+22+30+45)/4 which equals 29

Answer 2

The mean of the temperatures is 29°C, which corresponds to answer B.

Explanation:

1. Add all the values together.

For convenience reasons we are going to avoid the use of the Celsius symbol (°C) during the calculations.

`19+22+30+45=116`

2. Count the amount of given values.

There are 4 values of temperature.

3. Divide the total of the sum by the amount of given values.

`(116)/(4)=29`

4. Conclude.

The mean of the temperatures is 29°C, which corresponds to answer B.
