Answer:
A.
Step-by-step explanation:
The interquartile range for republicans is 185.5. The interquartile range for democrats is 186.5.
367.5 - 181 = 186.5
356 - 170.5 = 185.5
-20
Replace X by 3
f(3) = -2(3)^2+ (3)-5 = -20
10-[6-4+(5)]×2
10-[2+5]×2
10-(7)×2
10-14= -4
d₁ = 4 + 4 = 8
d₂ = 3 + 3 = 6
The area of the rhombus:
8 · 6/2 = 8 · 3 = 24 {u²]
First answer.
The mean is 80
