Please vote my answer brainliest. thanks!
A) 1104/ 138 = 8
B) 1st = 30/2 = 15, 2nd = 15/2 = 7.5, 3rd = 7.5/2 = 3.75, 4th 3.75/2 = 1.875, 5th = 1.875/2 = 0.9375, 6th = 0.9375/2 = 0.46875, 7th = 0.46875/2 = 0.234375, 8th = 0.234375/2 = 0.117 = 0.12
Answer is B
X² + 3x = 10
Convert to standard form.
x² + 3x - 10 = 0
factor x² = x * x
factor -10 = 5 * -2
(x + 5) (x - 2) = 0
x(x -2) + 5(x-2) = 0
x² - 2x + 5x - 10 = 0
x² + 3x - 10 = 0
x + 5 = 0 x² + 3x = 10
x = -5 -5² + 3(-5) = 10
25 - 15 = 10
10 = 10
x - 2 = 0 x² + 3x = 10
x = 2 2² + 3(2) = 10
4 + 6 = 10
10 = 10

I kinda went off what I knew
Hey at least I tried
Answer:
A. 7%
Step-by-step explanation:
We build the Venn's diagram of these probabilities.
I am going to say that:
A is the probability that a resident owns a car.
B is the probability that a resident owns a truck.
We have that:
![A = a + (A \cap B)](https://tex.z-dn.net/?f=A%20%3D%20a%20%2B%20%28A%20%5Ccap%20B%29)
In which a is the probability that a resident has a car but not a truck and
is the probability that a resident has both a car and a truck.
By the same logic, we have that:
![B = b + (A \cap B)](https://tex.z-dn.net/?f=B%20%3D%20b%20%2B%20%28A%20%5Ccap%20B%29)
4% of residents own both a car and a truck.
This means that ![A \cap B = 0.04](https://tex.z-dn.net/?f=A%20%5Ccap%20B%20%3D%200.04)
56% of residents own a car
This means that
. So
![A = a + (A \cap B)](https://tex.z-dn.net/?f=A%20%3D%20a%20%2B%20%28A%20%5Ccap%20B%29)
![0.56 = a + 0.04](https://tex.z-dn.net/?f=0.56%20%3D%20a%20%2B%200.04)
![a = 0.52](https://tex.z-dn.net/?f=a%20%3D%200.52)
What is the conditional probability that a person who owns a car also owns a truck?
![P(B|A) = \frac{A \cap B}{A} = \frac{0.04}{0.56} = 0.07](https://tex.z-dn.net/?f=P%28B%7CA%29%20%3D%20%5Cfrac%7BA%20%5Ccap%20B%7D%7BA%7D%20%3D%20%5Cfrac%7B0.04%7D%7B0.56%7D%20%3D%200.07)
So the correct answer is:
A. 7%
