If i worked for 9: 15am to 12: 45pm how many hours did i worked

3:30 (Three hours and thirty minutes)

Every hour has 60 min, so:

From 9:15am to 10:00am he worked 45min;

From 10:00am to 12:00am he worked 2h;

From 12:00am to 12:45pm he worked 45min;

Now we sum everything:

45 + 45 = 90min = 1:30h

1:30 + 2h = 3:30

Hope it helped,

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
