7 students......receive 0
5 students......receive 3......thats $ 15
7 students.....receive 5.......thats $ 35
3 students.....receive 6.......thats $ 18
2 students.....receive 8.......thats $ 16

the mean (or the average) can be found by adding up the total amount received and dividing by how many students there were.

so the mean is : (0 + 15 + 35 + 18 + 16) / (7 + 5 + 7 + 3 + 2) =
                           84 / 24 = 3.5 <==

"More than 60% of the students scored below the mean on the last test." Can this statement be true? Why or why not?
Lelu [443]
The mean is the average of a set of numbers.

So if the remaining 40% of students score 100 points, and the 60% score like 50 points, then the mean would still be 70 points because of the 40% of students that scored super high.

So yes, it can be true.

your local gas stations are having a price war during the past seven days they have lowered the price of regular gas by $0.2 eac
Serga [27]
<h2>Answer with explanation:</h2>

Let x denotes the number of days and y denotes the total change in gas price ( in dollars).

Given : During the past seven days the price of regular gas is decreased by $0.2 each day.

Rate of decrease =$0.2 per day

Then , Total change in gas price = Rate of decrease x Number of days

i.e.y= 0.2 \times x

i.e. y=0.2x         (1)

To find the total change in gas price in 7 days , we put x= 7 in (1) , we get

y=0.2(7)=1.4    

Hence, the total change in gas price in 7 days = $1.4
