The new science and math building on campus has four elevators each designed to carry a maximum of 8 people. A building safety study has found that the combined weight of 8 people can be modeled by a normal distribution with mean of 1400 pounds and a standard deviation of 120 pounds. Using the figure of a standard normal distribution, is the following statement valid or not valid?

We would expect the total weight of 8 people to be between 1250 and 1550 pounds more than 75% of the time.

you start with $5 and save $10 a week until you have at least $45wer

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%

step-by-step explanation:

*calories burned = (weight)(calorie factor)*

calories burned = 180 (0.65)

calories burned = 117

the calories he used up is 117, which is 65% of his weight.
