In scientific notation, what is the sum of
2.3 X 10-and 5.4 X 10-4?
A 2.84 X 10-3
B
C
5.63 X 10-3
7.7 x 10-7
D
12.42 X 10-12

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

b is the answer that makes most sense
