A new battery's voltage may be acceptable (A) or unacceptable (U). A certain flashlight requires two batteries, so batteries will be independently selected and tested until two acceptable ones have been found. Suppose that 92% of all batteries have acceptable voltages. Let Y denote the number of batteries that must be tested.
a) What is p(2), that is P(y = 2)?
b) What is p(3)?c) To have Y = 5, what must be true of the fifth battery selected?
i. The fifth battery must be an A.
ii. The fifth battery must be a U.

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.

the answer is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12

step-by-step explanation:

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.
