Imagine in your mind that a fair 20-sided die, with faces labled 1,2,3, . . ., 20, is rolled ten times. What is the expected value of the sum of the rolls? A. 20

B. 60

C. 100

D. 105

P. S: This isn't part of the problem but put this link in. https://youtu. be/ub82Xb1C8os

they used 313 gallons of paint

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.

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?

the answer is 9 because the question is telling how much it be together.
