Answer:

I dont know but I can direct.

Step-by-step explanation:

The median is a middle number in a sorted, ascending or descending, list of numbers.

The quartile measures the spread of values above and below the mean by dividing the distribution into four groups.

The interquartile range describes the middle 50% of values when ordered from lowest to highest.

It takes nate four hours to paint a wall and it takes jill seven hours to paint the same wall about how many hours will it take

loris [4]

If Nate paints the wall in 4 hours, it means that he can paint 1/4 of the wall every hour.

Similarly, if Jill paints the wall in 7 hours, it means that he can paint 1/7 of the wall in one hour.

So, together, they paint the following fraction of the wall in one hour:

$\frac{1}{4}+\frac{1}{7} = \frac{4+7}{28} = \frac{11}{28}$ .

At this rate, they need 28/11 hours to paint the whole wall, in fact, after that amount of time they paint

$\frac{11}{28}\frac{28}{11} = 1$

i.e. the whole wall
