In the question you provided above what do you mean can you please give more details.
To find the mean of a data set, you have to add all of the numbers and divide by the number of data.
So
50 + 54 + 62 + 48 + 49 + 52
To get 315.
315 divided by 6 is 52.5
So the mean of he data set is 52.5
Hope this helps :)
6.25x = 225.65
x = 225.65 / 6.25
x = 36.104....so u would basically have to work 37 hrs
The answer is 2 x10 = 20
To the power of b which is 15
