Answer:
C. Brandon. He has a 0.63 probability of attending both activities.
Step-by-step explanation:
Probability of attending Probability of attending
the Saturday activity the Sunday activity
Aisha 0.90 0.68
Brandon 0.71 0.89
Given that attendance at one activity is independent of attendance at the other, the probability that Aisha attends both activities is: 0.9*0.68 = 0.61, and the probability that Brandon attends both activities is: 0.71*0.89 = 0.63
Answer:
x = 4
Step-by-step explanation:
Since the triangles are similar, you know that the sides are equally proportional to all the other ones.
What I do is set up two fractions:
=
Make sure that the bigger sides are on the same side of the fraction as each other!
Now, you solve for x.
2(x + 2) = 3x
2x + 4 = 3x
-x + 4 = 0
x = 4
I hope this helps!
This would be the same as 8x=-72, when you divide everything by 8, you get
x = -9
Well, $107 times 7 is $749, is that what ypu needed?
You would combine like terms to get x^2 - 6x + 34
