Total number of marble = 10
3green
2red
5 blue
Probability that the first marble is red = 2/10
Probability that the second is blue = 5/9(a reduction in the total number of marbles, because after the first marble was picked it wasn't replaced)
Probability of 1st and 2nd being red and blue respectively = 2/10 × 5/9
=1/9....
Hope this helped...?
Answer:
1=c
Step-by-step explanation:
1=c
2=d
3=e
4=a
5=b
I know 1 and 2 are correct, but I am not sure about the others
I'm not too sure how to explain this, sorry
Because ΔQRS is congruent to <span>ΔTUV, the the segments GS and TV are also congruent due to the letter order (Q and T are first and S and V are 3rd.) Since they are congruent QS=TV. So 3v + 2 = 7v - 6
</span><span>
</span><span>Work:
</span>3v + 2 = 7v - 6
+6 +6
3v + 8=7v
-3v -3v
<u>8</u> = <span><u>4v</u>
</span>4 4
2 = v
3(2) + 2 = GS
6+2 = GS
8 = GS
7(2) - 6 = TV
14-6=TV
8 = TV
Final Answer: 8=QS and 8=TV
Answer:
∠CEB
Step-by-step explanation:
The vertical angle is one that is directly <em>opposite</em> to the original angle. In this image of two intersecting lines, it looks like the angle ∠CEB is directly across from our angle ∠DEA. So, the angle ∠CEB is <em>vertical to</em> ∠DEA.
Hopefully that was helpful! :)
