An elevator can safely hold 3,500 lbs. A sign in the elevator limits the passenger count to 15. If the adult population has a me

NeTakaya

Answer:

$1.75*10^{-27}$

Step-by-step explanation:

If, collectively, 15 people weigh more than 3500 pounds, that means each person must weigh more than 3500/15 = 233.33 pounds.

If the distribution for population weights is normal at mean = 180 and standard deviation = 25 lbs, that means the probability for 1 person to weigh higher than 233 lbs is

$1 - P(x > 233, \mu = 180, \sigma = 25) = 1 - 0.984 = 0.016$

For all 15 people to have higher weigh than that then the probability is

$0.016^{15} = 1.75*10^{-27}$

This is indeed very unlikely to happen

S_A_V [24]

Answer:

You could answer this two ways.

Step-by-step explanation:

Method 1: Set up proportion

x/40=55/100

Cross-multiply and you will get..

2200=100x

x=22

Method 2: Use decimals

As we saw in the first method, 55 percent is equal to 55/100. 55/100 is equal to 0.55.

You can multiply 0.55 and 40 to get the answer as well.

0.55 times 40 is 22.

Hope this explanation helped! ☺️
