Answer: the perimeter of the Pentagon is 12.5 inches
Step-by-step explanation:
Let x represent the length of each side of the Pentagon.
A rectangle has width twice as long as the side of the pentagon. This means that the width of the rectangle, w is 2x
The rectangle has length four times as long as the side of the pentagon. This means that the length of the rectangle, l is 4x
The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(l + w)
The perimeter of the rectangle is 30 inches. This means that
2(2x + 4x) = 30
12x = 30
x = 30/12 = 2.5
A Pentagon has 5 sides. This means that the perimeter of the Pentagon is
5 × 2.5 = 12.5 inches
Alright, I'll explain them as well.
1. The answer is 7, The open end of the sign is always to the larger number.
2. The answer is 4, and again, the open end of the sign is always to the bigger number.
3. The answers is two, and as before, 2 is the only number that will not make it negative or 0 and make the larger number be to the open end of the sign.
4. I'm not entirely sure on this one, so I won't answer it because I don't want to be the reason you get it incorrect.
5. For this one, divide 180 by 2.25, this will give you 80. The inequality should be 2.25k ≥ 180, k <span>≥ 80.
I hope this helps, have a nice day :)</span>
Answer:
Expected value of profit is ≅ $15.80
Step-by-step explanation:
from the Question,
Let the variable X represents the expected value of profit. X is called as random variable because picking a number from 000-999 digits is a Random process.
P(win) =
So, P(lose) =
Suppose that,
we really want to win this lottery. so we can go to the store and spend $1000 to buy all ticket (from 000 - 999). This would ensure your winning of $500 with one of the tickets (for a $499 profit), but the other 999 would be losers (for a $999 loss).
What would be your average winnings on a per-ticket basis?
∑
=
Here,
Standard deviation of the expected winnings
∑
= ∑
Taking square root of the variance to get the standard deviation:
SD(x) =
≅ $15.80
Hence
The expected value of profit is ≅ $15.80
