At the Olympic games, many events have several rounds of competition. One of these events is the men's 100-
meter backstroke.
The upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 Olympics.
The lower dot plot shows the times of the same 8 swimmers, but in the semifinal round.

Which pieces of information can be gathered from these dot plots? (Remember that lower swim times are
faster.)

Choose all answers that apply:

A. The swimmers had faster times on average in the final round.

B. The times in the final round vary noticeably more than the times in the semifinal round.

C. None of the above

80 the answer is 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.
