<u>Problem</u>
A bag contains 6 blue marbles, 10 red marbles, and 9 green marbles. If two marbles are drawn at random without replacement, what is the probability that two red marbles are drawn?
<u>Work </u>
Probability = no. of favorable outcomes /total no. of outcomes
Probability of getting a blue marble=5/5+6+9=5/20
Probability of getting a red marble=6/20−1=6/19
5/20×6/19
<u>Answer</u>
3/20
So it is C.
Answer:
∠U = 56.4
Step-by-step explanation:
We can use trigonometric functions to solve this
Here we are given the opposite side of ∠U as well as the adjacent side.
When dealing with the adjacent and opposite side we use sin
Sin = Opposite side / Adjacent side
Opp = 5 and adj = 6
So
Sin(U) = 5/6
* take the inverse sine of both sides *
arc(sin)(u) = u
arcsin(5/6) = 56.4 *( rounded to the nearest tenth )
∠U = 56.4
Standard form for circle with radius r and center (h,k) is
(x-h)^2+(y-k)^2=r^2
r=36
center at -2,-7
(x-(-2))^2+(y-(-7))^2=36^2
(x+2)^2+(y+7)^2=1296
