Robert plays cricket. He hit the ball in such a way that it goes up 180 feet in 45 seconds. What is the speed of ball in feet per second?

4 feet per second

Step-by-step explanation:

Hi there!

where v is velocity (speed), D is distance and t is time

Plug in the known values (D=180 feet, t=45 seconds)

Therefore, the speed of the ball is 4 feet per second.

I hope this helps!

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.

don't report but were is the digram
