Answer:
first one is 120cm
second one is 7.5 miles
Step-by-step explanation:
one book is 3.75
maximum books are 25
so 25×3.75 = 93.75
second question he crosses 0.63 to go for work
and 0.63 to go home so in one day he crosses 1.26 miles

<h3>What is Standard Deviation and Mean?</h3>
A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean.
The mean can be used to get an overall idea, or picture, of the data set.
Let Mean be 'm'
and standard deviation= 
So, m-2
=49
and, m +
=61
Solving the above two equation we get

Now, m= 61-
= 61-4
= 57
So , the mean of this test will be =57
