Hey there!
We know options. B and D aren't going to be your answer because they are way too big to be equivalent to 200
In order for you to find out which one is equivalent to 200 you have to calculate you late the options until you get to 200 and then you could do process of elimination!
It can't be A because 2/10 = 0.20 aka 20%
It can't be option. C because 10/20 = 0.50 aka 50%
So none of the above would be your answer
The correct answer would most likely be: 10√2
Good luck on your assignment and enjoy your day!

Horizontal line is y=, because every point along that horizontal line will have the same y value. So, now look at the point and notice that the y value is 5. So the horizontal line with a y value of 5 is y=5. Thus the answer is f.
Answer:
The quadratic equation is: 
Step-by-step explanation:
If the roots of the quadratic equation are "-6" and "6", then it must have the following factors: 
Therefore, we can write the equation in factor form as:

where a is a real number constant factor. Now, this equation in standard form will look like:

Therefore, using the information about the leading coefficient being "1" (one), we derive that the constant factor
must be "1". The final expression for the quadratic becomes:

Answer:
P(A and B) = 0.1 = 10%
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is

In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question, we have that:

What is P(A and B)?


P(A and B) = 0.1 = 10%
So Serena is 10, and her mother is 3 times ten, so her mother is 30. And if we take 30 minus 10 we will have the age of the mom when Serena was born, which is 20. So we know that when Serena is 20, her mother will be 40. So when Serena is 20, she will be half of her mother's age. 40 × 0.5 = 20.
