Answer:
Following are the solution to the given points:
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:

Answer:
(a) The system of the equations
has no solution.
(b) The system of the equations
has many solutions 
Step-by-step explanation:
(a) To find the solutions of the following system of equations
you must:
Multiply
by 2:

Subtract the equations

0 = -3 is false, therefore the system of the equations has no solution.
(b) To find the solutions of the system
you must:
Isolate x for 

Substitute
into the second equation

The system has many solutions.
Isolate y for
