A = (16 * 9) + 1/2(16+31)(15) + 1/2(20)(31)
A = 144 + 352.5 + 310
A = 806.5
answer is A
806.5
If I am correct, it would be C because there are only 2 sides on the coin, so you have a 50/50 chance of heads again or tails
<em>1.) </em><em>3</em>
<em>Take the given equation </em>
<em>2y=6x-8</em>
<em>Now divide by 2 on each side</em>
<em>y=</em><em>3</em><em>x-4</em>
<em>Slope is </em><em>3</em>
<em>2.) y=1/3x-4</em>
That would be the first choice:
5^0 = 1 , 5^1 = 5, 5^2 = 25 and so on up to 5^4 = 625
The answer is 20 because 3 is closer t 1 than 10
