Answer:

x^{2} + 7x+12=0

Step-by-step explanation:

Roots of the equation are -4 and -3.

Quadratic equation can be written as

(x+4)(x+3)=0\\x(x+3)+4(x+3)\\x^{2} +3x+4x+12\\x^{2} + 7x+12=0

PLEASE I NEED HELP! How do you find y?
myrzilka [38]

In this example, y is equal to 8.

In order to find this, first note that the two x value expressions create a straight line. That means when we add them together they will equal 180. this will give us a value for x.

x + 10 + 10x - 61 = 180

11x - 51 = 180

11x = 231

x = 21

Now that we have the value of x, we can do the same for the straight line created by the x + 10 angle and the 18y + 5 angle.

x + 10 + 18y + 5 = 180

(21) + 10 + 18y + 5 = 180

36 + 18y = 180

18y = 144

y = 8

Can someone explain this step by step for me? its from a review so ignore my wrong answer. Thank you!

Answer:

P(\text{Male}|\text{Divorced})\approx0.092

Step-by-step explanation:

\displaystyle P(\text{Male}|\text{Divorced})=\frac{P(\text{Male and Divorced})}{P(\text{Male})}=\frac{\frac{9.6}{214.7}}{\frac{104.5}{214.7}}\approx0.092

We can even break this down further by simply only looking at the total amount of males, and finding the proportion of males that are divorced, which is \frac{9.6}{104.5}\approx0.092, the same value.

Note that P(Male | Divorced) means the probability of choosing a male, given (|) that person is divorced.
