Find the mean of given data set: 2, 5, 5, 6, 7, 1, 2

would be the mean.

Step-by-step explanation:

The mean is when you add up the numbers and divide it by how many numbers there are.

There are 7 numbers. Divide it.

:)

The mean is 4.

Step-by-step explanation:

Mean simply means average. To do so, just add up all the numbers and divide by the amount of numbers present.

2 + 5 + 5 + 6 + 7 + 1 + 2 = 28/7 = 4

it's

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.
