Answer:

5.94

Step-by-step explanation:

To find the mean, you need to add the numbers and divide it by however many numbers you have.

4.7 + 4.2 + 8.2 + 9.5 + 3.1 = 29.7

There are 5 numbers, so divide the sum by 5

29.7/5 = 5.94

Last year there were 225 employees and 25 supervisors at Corpcon Company. If 27 more employees are hired, how many supervisors n
MrRa [10]
In order to solve this, you need to put it into a fraction form.

First for every 225 employees there's 27 supervisors.
25 x
___ = ___
225 252

I got the 252 by adding 225+27(who are the new employees)

So then you need to cross multiply. And get them to equal the same number.

So 25×252= 6,300
Then Divide 6,300 by the old denominator 225.
6,300÷225= 28 new employees

Therefore there will be a total of 28 employees.

Hope this helped!
