Mary went to the park with Amy at 2:30 pm. They played for 1 hour 30 min. At what time did the finish playing? Give your answer in 24-hour clock format and also draw the clock.

4:00 pm

Step-by-step explanation:

4:00

Step-by-step explanation

First, we add the minutes. 30 + 30 is 60. One hour is 60 minutes so we add 1 when we are adding the hours. 2 + 1 + 1 = 4 so it is 4:00 when they finished playing. I cannot draw the clock because it is not letting me do so.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
