Step-by-step explanation: what is the question
Answer:
G
Step-by-step explanation:
"Any particular event either (a) will happen or (b) won't happen."
That statement above is a certainty, probability = 100% = 1
This means the probability that event E <u>will </u>happen plus the probability that even E <u>won't </u>happen must add up to 100% = 1
So we can always say --> prob(E) + prob (not E) = 1
The probability you will roll a 5 on a fair, six-sided die is 1/6.
So we use that to find the probability of not rolling the 5.
1/6 + prob(not E) = 1
prob(not E) = 1 - 1/6 <---- This is answer G
prob(not E) = 5/6
Hope this helps.
To complete the square, the second degree term must have a coefficient of 1.
Since the second degree term here has a coefficient of 4, we start by dividing each term on both sides by 4.



Now we can complete the square.
First, we need to find what number completes the square.
We take the coefficient of the first degree term, -7 in this case.
Divide it by 2 and square it. -7 divided by 2 is the fraction -7/2.
Now we square -7/2 to get 49/4.
We add 49/4 to both sides.



angle A = angle B corresponding angles
8x - 8 = 5x + 25
3x = 33
x = 11
angle B
5x + 25
55 + 25
80°
