Question

In tryouts for the olympics a speed skater had times of 44,64,43,45,42,79 and 4,228 seconds find the average time add numbers

Answer 1

Answer:

$Average = 43.29$

Step-by-step explanation:

Given

Time: 44.64,43.45,42.79 and 42.28

Required

Determine the average time

Average or mean is calculated as thus;

$Mean = \frac{\sum x}{n}$

Where

$\sum x$ = sum of observation

n = number of observation = 4

$Average = \frac{44.64 + 43.45 + 42.79 + 42.28}{4}$

$Average = \frac{173.16}{4}$

$Average = 43.29$

Hence, the average time is 43.29
