Question

The minimum temperature of a town in a certain week was recorded as 20°C 18 9-C. 21. 4°C. 20. 3 C. 22°C. 18. 8°C and 19°C. Find the average minimum temperature of the week.​

Answer 1

Given,

$\sf Minimum\: temperature\:=\:20\degree C \: ,\:18.9\degree C \: ,\:21.4\degree C \: ,\:20.3\degree C \: ,\:22\degree C \: ,\:18.8\degree C \: ,\:19\degree C.$

To find the average temperature,

$\sf \color{lime} \boxed{Average\:=\: \frac{Sum\:of\:observations}{Number\:of\: observations}}$

$\large \sf Average\:=\: \frac{20 \: + \: 18.9 \: + \: 21.4 \: + \: 20.3 \: + \: 22 \: + \: 18.8 \: + \: 19}{7}$

$\sf Average\: temperature\:=\; {\underline{5.77142857143 \degree\:C}}$

Answer 2

Answer:

5.771429°C

Step-by-step explanation:

average = sum of all observations / number of observations

average = ( 20 + 18.9 + 21.4 + 20.3 + 22 + 18.8 + 19 ) / 7
