Keith has p pennies, n nickels, and d dimes in his pocket. the total number of coins is 9. the expression represents the value of the coins, which is equal to $0.53. he has two fewer nickels than dimes. how many pennies does keith have? keith has pennies. the solution is

keith has 3 pennies, 2 nickels, 4 dimes

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.

$5.41
