Twenty-five students reported how many email accounts they have. the dot plot below shows the data collected: a dot plot is shown with the title email accounts of students. the values on the horizontal line are 1, 2, 3, 4, 5, and 6. the label along horizontal line is number of email accounts. put 8 dots vertically along the value 1, 6 dots vertically along the value 2, 5 dots vertically along the value 3, 3 dots vertically along the value 4, 2 dots vertically along the value 5, and 1 dot vertically along the value 6. what do the dots above the number 3 represent? there are exactly 3 students with 5 email accounts. there are exactly 3 students with less than 5 email accounts. there are exactly 5 students with 3 email accounts. there are exactly 5 students with less than 3 email account

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.

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.
