For the first event
P=3/(5+3)=3/8=0.375
Total became 2 red and 5 blue .... 7 total
For the second event
P=2/(5+2)=2/7= 0.2857
O = 7*180 = 1260 degrres
sin O = 0
Answer: 7
Step-by-step explanation:
3n=21
n=7
Hey!
Hope this helps...

When looking at this graph we see 2 things:
(1) How they made the graph, looks awful, anyway...
(2) They practically give you the answer...
When finding an answer to a question like this, you want to use a formula (like this):
A = t * p (where A is the amount of people, t is total amount of people, and p is percent of people / 100)...
So... we fill in the givens...
We know t = 400, and (by looking at the graph) we see that p is around 0.10 and 0.15. So for our sake we'll make p = 0.13 (about halfway)...
A = 400 * 0.13
A ~ 52
The answer is: About 52 people bought 20 items...
And because we got 52, and 52 is close to 54...
<em>The Answer: B.) 54</em>
Answer:
A
Step-by-step explanation:
The side lengths must satisfy the Pythagorean Theorem to be a right triangle. The formula is 
where a is the smallest side, b is the medium side, and c is the largest side. Test each set of numbers.
This satisfies the theorem. Since this is a multiple choice question, only one solution is possible. A is the solution.
