Elsa knows that for every bushel of apples she sells she earns $9 and for every basket of pears she earns $11. she uses the expression 9a + 11p to keep track of her earnings.

part a: identify the coefficients and variables in the expression. (3 points)

part b: how many terms are in the expression, what are they, and how do you know? (4 points)

part c: which term in the expression shows the total earned from selling baskets of pears? (3 points)

i only need with b and c ?

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.
