If 2 1/2 pounds of bananas cost 1.89 what is the cost per pound?

So we can turn the fraction into a decimal to make it easier

2.5 lbs (pounds)

since the bananas cost $1.89, we need to divide it with 2.5

1.89/2.5

=0.756

the answer would be $0.76

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.

b.-4 units

all you   do is count how many times you move
