45 POINTS if i get wrong this question I'll not mark anyone

By adding the two, they are both the same. Except one is negative.

So they cancel out,

which leaves you with (C).

It is zero. It's like adding -1 and +1, which gives you the sum of zero.

If you wanna get fancy, you can also rewrite the problem as

-6.80 & 6.80. Because 4/5 = .80

it could be A or D but my best guess is D not sure though

Step-by-step explanation:

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
