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.

Answer:
≈ 488.8
Step-by-step explanation:
So we wanna find x for 0.156x = 76.252;
What we have to do is to divide both sides of the equation by 0.156 to isolate the variable
If you are allowed to use a calculator then you can get the answer:
It equals around 488.8
If you want to solve it by hand, you can multiply both by 1000 to get:
76252 divided by 156.
Answer:
477.47 revolutions
Step-by-step explanation:
From the information given:
The formula for calculating the circumference = 2π r
Given that the radius of each wheel = 25 centimeter
Then, the circumference = 2 π (25)
= 50π cm
The distance traveled in 5 minutes is as follows:
Given that:
The speed = 45 km/ hour
i.e.
1 hour = 45 km
In an hour, we have 60 minutes
So, 60 minutes = 45 km
1 minute = 45/60 = 0.75 km
To cm;
0.75 km = (0.75 × 1000) m = 750 m
750 m = 750 × 100 = 75,000 cm
∴
The number of revolution in 5 minutes sInce 1 revolution = 50π cm is:
= 75,000 cm/ 50π cm
= 477.47 revolutions in 5 minutes
