A random sample of laptop computers at an electronics store shows
that 1 of the 25 sampled laptop computers has a malfunction. There
are 300 laptop computers at the electronics store. Estimate the numbe
of laptop computers at the electronics store that have malfunctions.

12

Step-by-step explanation:

well 25 goes into 100 4 times, so if there is 300 that means you have 4 in every 100. So if you take 4 times the number of hundereds you have which is 3 that gives you 12

00

step-by-step explanation:

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
