Answer:
.56
Step-by-step explanation:
The probability of a certain event always adds up to 1. Like if you are flipping a coin, 1/2 chance tails + 1/2 chance heads = 1. The coin can't do anything else than tails and heads.
In this case, either Ricky or Nicky is absolutely guaranteed to win the game.
So the probability Nicky wins is
1 - .44 = .56
Answer:
2,000,000
Step-by-step explanation:
First of all, I think that you are asking:
=?
So, because multiplication is commutative, we are allowed to group together what we know and what we will deal with later:
can be rewritten as
10*10*100*2=20,000
So, what we do know is that when we take the square root of a number and multiply it by itself (or "square" it) we will get back the number that we started with.
So:
We can rewrite what we had up top as:
Step-by-step explanation:
A supplementary angle is an angle that is 180 degrees. We are given two angles that add up to 180, but we need to solve for x first.
The first step is to solve both angles. We know that both angles added together are supplementary, so they are equal to 180.
4x + 8 = unknown angle
6x + 3 = unknown angle
(4x + 8) + (6x + 3) = 180
Because we know a supplementary angle is 180 degrees, we can solve for x to find both angles.
Solve for x.
(4x + 8) + (6x + 3) = 180
10x + 11 = 180
10x = 169
x = 16.9
Now, we know the value of x, so we plug in x for both angles to determine which angle is smaller.
4x + 8
4(16.9) + 8
67.6 + 8 = 75.6 degrees
and the other angle
6x + 3
6(16.9) + 3
101.4 + 3 = 104.4 degrees
Now we know that the smaller angle is 75.6 degrees.
Also, to make sure the math is correct, when plugging in both numbers after finding x, they should add to 180.
75.6 + 104.4 = 180 so we know they are supplementary for sure.
Good luck!
Well, the first 16 were about 16*75=$1200 extra. The last 8 were $720 lost. Thus, the total profit is $480. He bought them with $7200, which means the profit is around 6.67%.
