5. A car advertisement asserts that with the new collapsible bumper system, the average body repair cost for the damages sustained in a collision impact of 10 miles per hour does not exceed $300. To test the validity of this claim, Consumer Reports collects 5 cars as their experimental samples. 5 cars are crashed into a stone barrier at an impact force of 10 miles per hour and their subsequent body repoair costs are recorded. The mean and the standard deviation are found to be $358 and $45, respectively. Do these data strongly contradict the advertisement

x = 25/2304

step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.

c: lkllmn.

hope it's you

i think that you should ask google for the answer to that problem because if we don't know it google does
