Answer: C which is -3,000
Step-by-step explanation:
Hi there!
The easiest way to think about this is what cases Elba will win. We know that Steve will win if tails comes up at least twice. He will lose if tails comes up only once or 0 times. This means that heads will either come up twice or 3 times, meaning Elba will win <u>if tails comes up at least twice.</u>
Thus, looking at this, we can see (as heads and tails is a 50 50 chance) that the probability is the same because the <u>situation in which they win is the same, but flipped</u> (from heads and tails).
Thus, this means that Elba wins 1/2 of the time.
Hope this helps! Feel free to let me know if you have any questions about this specific question.
Answer:
-1.
Step-by-step explanation:
1/m = m^-1.
We can show this is correct if we simplify the following:
m^2 / m ^3 = m * m / m * m* m = 1/m
By the law of indices: m ^2 / m^3 = m^(2-3) = m^-1.
Answer:
The height of the beam is: 
Step-by-step explanation:
The radius of the tunnel is r = 15 feet
The distance of the beam from the center of the tunnel is:
We have a right triangle, where:
- The Hypotenuse is 15 feet
- One side is 9 feet
- The other side is the height of the beam
Let's use Pythagoras theorem.
Therefore, the heigh of the beam is:
I hope it helps you!
Answer:
Step-by-step explanation:
