First, I would show all the outcomes possible. To determine the number of the total outcomes, you use the formula: rⁿ, where r is the number of outcomes in 1 flip, and n is the number of lips. Thus, 2³ = 8 outcomes. These outcomes are:
1. HHH
2. TTT
3. HHT
<em>4. HTT</em>
5. HTH
6. THH
<em>7. TTH</em>
<em>8. THT</em>
From the given outcomes, there are <em>3 outcomes</em> that has at least two tails. These are the ones in bold characters.
Answer:
E
Step-by-step explanation:
I got 114 meat balls
i multiplied 25x4 and 7x2 and added the 2
so 114
My guess is that you're doing the Law of Cosines? You have everything you need for that except the angle theta, which is the thing you need to find. It's set up like this: (8)^2 = (10)^2 + (5)^2 -[2(10)(5)cos A] I used A instead of theta. Doing that math, you have: 64 = 100 + 25 -[ 100 cos A]; 64 = 125 - 100 cos A;
-61 = - 100 cos A; -61 / -100 = cos A; .61 = cos A. Now use your inverse function on your calculator to find cos^-1(.61) and that equals 52.4
