Question

A student measured the temperature in degrees Celsius for several winter days and recorded the data in a list. Find the average of the temperatures listed.

a) -2.8°
b) -0.5°
c) -3.5°
d) 0.5°

Answer 1

The average temperature, calculated from the given data, is approximately -1.7°C, which is not one of the provided options.

Step-by-step explanation:

To find the average temperature, sum up all the recorded temperatures and divide by the total number of days. Let's denote the temperatures as
`\(T_1, T_2, \ldots, T_n\)` for each winter day.

Average Temperature =
`(T_1 + T_2 + \ldots + T_n)/(n) \]`

For example, if the recorded temperatures are -2°C, -1°C, 0°C, and -3°C for four days, the average temperature is:

Average Temperature =
`((-2) + (-1) + 0 + (-3))/(4) = (-6)/(4) = -1.5°C \]`

So, the student needs to perform a similar calculation for their recorded data to find the average temperature. It's important to sum up all the temperatures and then divide by the total number of days to obtain an accurate average.

Unfortunately, none of the provided options matches the calculated average of approximately -1.7°C. This discrepancy might arise due to rounding in the answer choices or potential errors in the data provided.
