Oofrence

could a mod take this down

I think this may be a joke but i wil ldo it nonetheless

I assume you are trying to find f

f/2 = 8

f = 16

31 rounds to 30, and 936 rounds to 940

940 + 30 = 970 (B)

The difference between 30 and 45 is 15

15/30 = 1/2, so the percent increase is 50%, or D

In total there are 5 + 3 + 2 = 10 marbles in total

The probability that the first one drawn out 5/10 = 1/2, and the chance that the second will be red is 2/9, because there is no replacement

1/2 x 2/9 = 1/9

The probability that the first one drawn out will be green and the second one is red is 1/9

nvm i found out how to do it

you should use latex and remove the $ signs, don't just copy it over from whatever website you are on

1. C, you are only squaring the x and multiplying it by 3.14, not anything else

2. C, to find the difference of two things, you subtract one from the other

3. A, you are buying m notebooks and each is 2.50, so the total is 2.50m and the same goes for the pens but n and 1.25 instead.

Thanks!

There must be 2 math books on either side, and there are 3 to choose from, so there are 3 possible books for one end, and 2 for the other. Therefore there are 6 possible ways to arrange the books.

For every possible way to arrange the two math books at either end, there is a number of possibilities to sort the 1 math textbook and 5 history textbooks. Then to find the possible ways of arranging you would do 6! = 720

720 x 6 = 4320 ways to arrange the books
