The graph above is what we call a quantitative dot plot. Each dot represents a specific number of
observations from a set of data. (Unless otherwise indicated, assume that each dot represents one
observation. If a dot represents more than one observation, that should be explicitly noted on the plot.)
The dots are stacked in a column over a category or variable, so that the height of the column
represents the relative or absolute frequency of observations in the category,
Using the dot plot above, answer or complete the following questions and tasks.
What is the quantitative variable being measured?

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.

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

there are infinitely many solutions.
