If 9 men can do a job in 24 days, how many men are needed to do the same job in 18 days? a. 11
b. 12
c. 15
d. 18

b  12

Step-by-step explanation:

1/(9*24)=1/(x*18)

9*24=18x

x=12

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

x= 149. 24+7=31. 180-31=149
