Step-by-step explanation:
Given values:


Total staff=40
In point a:
To calculate the median number first we arrange the value into ascending order and then collect the even numbers of calls that were also made. Its average of the middle terms is thus the median.
The midterms =55 and 59 so,
Median = 
In point b:
First-quarter

The first quarterlies are 
therefore the multiply of 0.5 by calculating the difference of the 7th and 8th term are:

therefore the it is multiply by the 0.5 for the difference of the 22nd and 23rd term:

In point c:
First decile 

In point d:
quartiles are:

The right answers for the decile are:

As for
will be available.

Answer:
the answer is 10 you round up a nine it keeps going to the end
First, multiply 50*3 to get the answer in feet which is 150 ft.
Then, divide 150 ft by 60 which would be 2.5 ft per second.
Percent means parts out of 100
105%=105/100=1.05
'of' means multiply
105% of 260=1.05 times 260=273
