The probability of college graduate getting employed within a year is 90 % 90%. The probability of a college graduate getting employed and buying a car within a year is 72 % 72%. What is probability that a college graduate bought a car within a year given that he got employed within a year?

Step-by-step explanation:

Let the probability of getting employed after graduated within a year be P(A)

and the probability of buying a car within a year be P(B)

Given that:

The probability of getting employed after graduated within a year = 90% = 0.9

Then; Let that be P(A)

The probability of getting employed and buying a car within a year = 72% = 0.72.

Then; Let that be P(A∩ B).

The probability that a college student will get both events is P(B/A)

P(B/A) = 0.80

step-by-step explanation:

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
