Getting two heads in a row does not change the probability of getting a tail. There is a 50/50 chance for both heads and tails each time you flip a coin, because there are two possibilities each equally possible. The 50% probability of getting a tails is not a guarantee. It's possible to get more heads than tails, or vice versa. What the probability means is that on average the results are about equal, and you have an equal likelihood of getting either result.
Mythbusters has an episode on this, actually. They explain it really well. I recommend you watch it.
Answer:
(301)^2-(300)^2
it is in the form of
a^2-b^2=(a+b)(a-b)
so,
(301+300)(301-300)
(601)(1)=601
We are given that the surface area A is:
A = 5.2 ft^2
To convert this into in^2, we know that there are 12
inches in 1 feet, so 12 in = 1 ft:
A = 5.2 ft^2 * (12 in / 1 ft)^2
<span>A = 748.8 in^2</span>
Sin(a+/-b)=sin(a)cos(b)+/-cos(a)sin(b)
sin(17+26)=sin(17)cos(26)+cos(17)sin(26)
Answer: sin(43)

<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define expression</u>
4(-8x + 5) - (-33x - 26)
<u>Step 2: Simplify</u>
- Distribute: -32x + 20 + 33x + 26
- Combine like terms (x): x + 20 + 26
- Combine like terms (Z): x + 46
