Answer:
Step-by-step explanation:
2 * 2 = 4u² (area of the central square)
2 * 2 : 2 = 2u² (area of one congruent triangle)
4 + 2 + 2 = 8u²
(u = units)
Answer: F-23=45
Step-by-step explanation:
The addition property of equality means that if:
A = B
then we can add the same thing in both sides of the equation, and the equality will remain balid, so:
A + C = B + C.
Then, the correct answer is the last option:
if
F - 23 = 45
Then we can add the same number to both sides, we can add 23 to both sides and in this way isolate F:
F - 23 = 45
(F - 23) + 23 = 45 +23 = 68
F + (23 - 23) = 68
F = 68
Answer:
The answer to this inequality would be x>2
Answer: The 9 in the second term is a coefficient that is true. I think that is the only thing that is true. There may be one more thing that is true.
The 10 in the third term is not a coefficient.
The 2 is not a constant
the x is not an exponent.
those are the ones that I'm sure about.
Please correct anything if i'm wrong.

Answer:
Expected value of the game: -$0.421
Expected loss in 1000 games: $421
Step-by-step explanation:
There are two possible outcomes for the event:
- There is a 1 in 38 chance of winning $280
- There is a 37 in 38 chance of losing $8
The expected value for a single game is:
![E(X) = \frac{1}{38}*\$280-\frac{37}{38}*\$8\\E(X)=-\$0.421](https://tex.z-dn.net/?f=E%28X%29%20%3D%20%5Cfrac%7B1%7D%7B38%7D%2A%5C%24280-%5Cfrac%7B37%7D%7B38%7D%2A%5C%248%5C%5CE%28X%29%3D-%5C%240.421)
The expected value of the game is -$0.421
In 1,000 plays, the expected loss is:
![L = 1,000*-\$0.421\\L=-\$421](https://tex.z-dn.net/?f=L%20%3D%201%2C000%2A-%5C%240.421%5C%5CL%3D-%5C%24421)
You would expect to lose $421.
