Which word best describes the degree of overlap between the two data sets? none

moderate

low

high
Two line plots with the same scale and interval, from zero to ten, with tick marks every one unit. The plots are stacked vertically for comparison. Each plot has sixteen data values. Values appear as x marks above the line. Upper plot data values are one x mark above two, one x mark above three, one x mark above four, two x marks above five, four x marks above six, three x marks above seven, two x marks above eight, one x mark above nine, and one x mark above ten. Lower plot data values are one x mark above 1, two x marks above two, three x marks above three, four x marks above four, two x marks above five, two x marks above six, one x mark above seven, and one x mark above eight.

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
