Three machines-A, B, and C-are used to produce a large quantity of identical parts at a factory. Machine A produces 60% of the parts, while Machines B and C produce 30% and 10% of the parts,
respectively. Historical records indicate that 10% of the parts produced by Machine A are defective,
compared with 30% for Machine B and 40% for Machine C. Suppose we randomly select a part
produced by one of these three machines at random.
a) Draw a tree diagram to represent this chance process. Make sure to include the probabilities of each
branch. (hint: start with three branches) (6 points)
b) What's the probability that the part is defective? (3 points)
c) What's the probability that is from Machine C, given the part is defective? (3 points)

if the probability is 1/12, 75 people will receive a $25 gift card

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.

add a pic of the graph, then ill edit this "answer" and solve it for you : 3
