What is the mean of 72,73,86,59,75,58,50,55
Rashid [163]
<h3><u>MEAN</u></h3>

Mean is the average. To find the mean of a data set, you have to add all the numbers and divide the sum by the amount of numbers you added.

<em>In this equation, you have 8 numbers. That means you will be dividing by 8. </em>

The first thing you need to do is add all the numbers. Add:

72+73+86+59+75+58+50+55 = \bf 528

Now that you have added all the numbers and got the sum, divide by 8. Remember that you will be dividing by 8 since you added 8 numbers.

Divide:

528 \div 8 = \bf 66

The mean is 66

It took two people to complete carpeting in 10 days. How many more workers need to be hired to complete the same job in 4 days?
IRISSAK [1]

so two fellows did all the carpeting in 10 days.

now, how long did "1" fellow work only?  well, it worked for 10 days.

how long did the other fellow work for?  well, it was working alongside the first one, and it was there for also 10 days.

so the two guys working together, really did 10+10 = 20 "days worth of work".  So that the whole carpeting job can be done in 20 "days worth of work".

now if we want to finish it in 4 days, 20 ÷ 4 = 5.

so if we hire 5 guys, since each one will do 4 days worth, 5*4 = 20 <- the whole job.

Please help!!!!!<br><br>Key features of Graphs
krok68 [10]
The graph is **increasing on the interval (-2, 1)**because the graph has a positive slope from x=-2 to x=1. It’s **decreasing at the intervals (-infinity, -2) and (1, infinity)**because the graph has a negative slope between the x values -infinity to -2 and is also decreasing between the x values of 1 and infinity.
