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: D) csc (2π/3)
<u>Step-by-step explanation:</u>
2π/3 is in Quadrant II
Quadrant II has a negative x-value and a positive y-value.
x-values are: cos & sec
y-values are: sin & csc
tan = y/x so will be negative in Quadrant II
A) sec = -
B) tan = -
C) cos = -
D) csc = + this works!
If we take the equation and multiply out the left side, we get....

+ 2xk +

=

+ x +

The x^2 and k^2 cancel out on both sides leaving us with this...
2kx = x
If we divide both sides by 2x to isolate k,
k ends up = 1/2
B is the answer.
The slope i got for the table is -1 because i divided -2 by 2.
The slope i got for the graph was 0 because 0/7 is 0.
-1 < 0
Step-by-step explanation:
Substitute the y in the 1st equation with the 2nd equation.
7x + 10(2x + 9) = 36
7x + 20x + 90 = 36
27x + 90 = 36
3x + 10 = 4
3x = -6
x = -2
So now we can find y.
y = 2x + 9 = 2(-2) + 9 = (-4) + 9 = 5.
So x = -2, y = 5.
