How could you estimate a 20% tip for a $23.25 restaurant bill

I would round 23.25 up to 24, then double that to get 48, and finally move the decimal point 1 spot to the left to get 4.80

Note how 20% of 24 = 20/100*24 = 0.2*24 = 4.80

This is an overestimate of the actual tip which is...

20% of 23.25 = 0.2*23.25 = 4.65

The overestimate occurs because I rounded 23.25 up to 24. I rounded up because it is easier to deal with whole numbers. Also, you should round up (not down) to make sure you clear over the target hurdle.

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

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
