Suppose that the manufacturer of a gas clothes dryer has found that when the unit price is p dollars, the revenue R (in dollars) is R(P) = - 5p2 +15,000p. (a) At what prices p is revenue zero?
(b) For what range of prices will revenue exceed $1,750,000?
(a) At what prices n is revenue zero?

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.

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20

4y - 6 + y^2 - 9 = y^2 + 4y - 15

y^2 term
