Answer:

As per dot plots we see the distribution of prices is close but majority of prices are concentrated in different zones. So MAD would be more similar by the look.

<u>Let's verify</u>

<h3>Neighborhood 1</h3>

<u>Data</u>

  • 55, 55, 60, 60, 70, 80, 80, 80, 90, 120

<u>Mean</u>

  • (55*2+ 60*2+ 70+ 80*3 + 90+ 120)/10 = 75

<u>MAD</u>

  • (20*2+15*2+5+5*3+15+45)/10 = 15
<h3>Neighborhood 2</h3>

<u>Data</u>

  • 100, 110, 110, 110, 120, 120, 120, 140, 150, 160

<u>Mean</u>

  • (100 + 110*3+ 120*3+ 140 + 150+ 160)/10 = 124

<u>MAD</u>

  • (24+14*3+4*3+16*3+16+26+36)/10 = 20.4

As we see the means are too different (75 vs 124) than MADs (15 vs 20.4).

What are the solutions to m^2 – 9 = 0? a. m = –9 and m = 0 b. m = –3 and m = 3 c. m = –3 d. m = 9
marysya [2.9K]
2 ways
zero product property
easy way

zero product
factor perfect square
m^2-3^2=0
(m-3)(m+3)=0
set each to zero
m-3=0
x=3

m+3=0
m=-3

m=-3 or 3

easy way
add 9 to both sides
m^2=9
sqrt both sides remember to take postive and negative roots
m=+/-3
m=-3 or 3
