It takes 9 builders 54 days to complete a house.
Dima020 [189]

It would take 6 builders  36 days to complete the same house.

<h3>Who are builders?</h3>

Builders are those person whose job is to build or repair houses and other buildings.

We have,

9 builders take 54 days to complete a house.

So,

1  builder will take  (\frac{54}{9})  days to complete a house,

In the same way,

6  builder will take  (\frac{54}{9}*6)  days to complete a house,

i.e.

6  builder   =(\frac{54}{9}*6)= 36 days.

Hence, we can say that it would take 6 builders  36 days to complete the same house.

The average age of instructors at a local college is 55, with a standard deviation of 6 years; the average salary is $37,000 wit
Lerok [7]
To solve for the coefficient of variation you will need this formula:
CV = (SD/X) x 100 
Where: CV = Coefficient of Variance
             X = Mean/average
             SD = Standard Deviation

To determine which one is more variable, just get the coefficient of both and compare.
                   AGE                                            SALARY
   
  CV = (6/55) x 100                             CV = (4,100/37,000) x 100
        = 10.90                                             = 11.08

Based on the results, salary is more variable because 10.90<11.08.
