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.

answer: this doesnt make any sense especially the photo.

step-by-step explanation:

3; 9 is 8 to -4

step-by-step explanation:

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
