12-5=7
21-12=9
x-21=11
21+11=32
x=32
Are you talking about 7-day period instead? Or is that really 70?
Anyway, the mean number of phone calls received over the period of time given would be 4 calls. I got to this answer through adding all of the calls and dividing them by the number of days.
D is the correct answer because it can be simplified
Answer:
The value of MX is 5.5 units.
Step-by-step explanation:
As the complete question is not given, the complete question is found online and is attached herewith

The diagram is attached with the solution.
As the line ZM is dividing the angle in two parts thus as the two angles are equal thus
The sides are given as
XZ=11
YM=3.5
YZ=7
Now by the theorem of the angles, the bisected angles are such that sin(<YZM)=sin(<XZM)
so

So the value of MX is 5.5 units.
