A bag contains 150 cubes that are black, yellow, and white. A student randomly selects a cube without looking and replaces it in the bag. If the student selected 3 black cubes, 8 yellow cubes, and 4 white cubes, which of the options below show a reasonable estimate for the total number of a certain cube in the bag? Select all that apply. A) 80 yellow cubes B) 30 black cubes C) 60 black cubes D) 40 white cubes E) 120 yellow cubes

true

step-by-step explanation:

me! what did you put for this question?

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.
