In order to have average 80 score from 5 tests, student needs to have 400 points (80%*500=0.8*500=400)

So far he has 63+72+88+91= 314

400-314=86

He needs to get 86 points from the last test.

Since he is obviously getting better at tests, i think he'll manage :)

A retail store during the holiday season sold (18) $400 computers, (11) $500 computers, (7) $600
dezoksy [38]

Answer:

$450

Step-by-step explanation:

A way to find the median of a set of numbers is by listing each number one by one and then slowly crossing out the smallest and biggest number one by one. If you end up with two numbers left, then you take the mean of those numbers. To do that, you add the two numbers and divide it by two.

If the two lines 2x+y=0 and y=3 are plotted on a typical xy coordinate grid, at which point will they intersect?
erastovalidia [21]
(-1.5,3) Y=3 which is up 3 and a horizontal line and 2x+y=0 can be written as y=-2x so in order to get -1.5 you have to make y=3 cause y=3 and when you do that it should look like 3/-2=-2/-2x so x=-1.5
