x^2 in the function that you typed is x * x ( x multiplied by x). It represents a second degree because there are only 2 "x"s multiplied together. If there were 3 "x"s multiplied together, we would have x^3. Since the highest exponent in this function is 2 (in x^2), we call this function a 2nd degree polynomial.
We're told that
a. We want to find 
. By definition of conditional probability,
By the law of total probability,
Then
(the first equality is Bayes' theorem)
b. We want to find 
.
since 
.
Answer:
C.) y=2x+3
Step-by-step explanation:
m=2 (given) or 2/1 to illistrate the point
take the slope from (1, 5) and down 2 and left 1 which will take you to the y-axis and 3
