-Stats- Researchers claim that the mean time (in years) that passenger cars were kept by the original owner before being sold is less than pickup trucks. Records of 40 used passenger cars and 40 used plokup were randomly selected For ears, the mean was 5.3 years with a known population standard deviation 2.2 years. For pickup trucks the mean was 7.1 years with known population standard deviation of years. Is there enough evidence to support the claim? Assume the populations are normally distributed and use a significance level of %

because 1.2 isnt half of 6 duh

do your own work and don"t cheat.

step-by-step explanation:

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%

we would need a picture of the quadrilateral in order to answer the question. also, it seems that the question is missing some components.
