Afitness company is building a 20-story high-rise. architects building the high-rise know that women working for the company have weights that are normally distributed with a mean of 143 lb and a standard deviation of 29 lb, and men working for the company have weights that are normally distributed with a mean of 183 lb and a standard deviation or 35 lb. you need to design an elevator that will safely carry 13 people. assuming a worst case scenario of 13 male passengers, find the maximum total allowable weight if we want to a 0.99 probability that this maximum will not be exceeded when 13 males are randomly selected.

1/4 because there is 4 grades.

i can you with this answer

step-by-step explanation:

you are playing an adventure game on your computer. you come across a troll who won't let you pass and there is no other way to get to the other side of the river except over the bridge he is guarding.

the troll is a nerd. he takes great delight in watching people struggle with his problems. very few get them. he only gives you one chance and then he changes the puzzle. you have to solve this one.

before you are four blocks. they are numbered 11,6, -7,21.

he tells that the answer he wants is minus and between -1 and - 2. you can use +, -, ×, ÷   ( and ) as many times as you like or no times at all. you don't like the way he's looking at you, but you need to cross the bridge. what do you do?
