The graph shows the number of states and Washington, DC, within each range of electoral votes for the 2020 presidential election. A histogram titled Electoral votes by states, 2020, has electoral votes on the x-axis and number of states on the y-axis. 0 to 3, 16; 3 to 6, 11; 6 to 9, 11; 9 to 12, 3; 12 to 15, 3; 15 to 18, 3; 18 to 21, 4. Which interval contains 11 states? Check all that apply. 0 to 3 3 to 6 6 to 9 9 to 12 12 to 15 15 to 18 18 to 21

we need the options

step-by-step explanation:

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

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
