Write 8.51*10^-4 in decimal notation

8.51*10^-4*(10÷10)

(8.51÷10) *10^-4*10

. 851*10^-3*(1000÷1000)

10^-3*1000*(.851÷1000)

1*.000853

=.000853

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

probability for j is 1/4

while

a is 1/6
