Hello,
Answer D: 4.30 in
The circomference is 27 in=2*π*R
==>R=27/(2π)=4.291834... ≈4.30 (in)
With dot plot if it’s symmetrical its the mean and MAD, so i think that.
Answer:
x = 11
y = 3
Step-by-step explanation:
4y+1=6y-5
-4y -4y
+1 =2y-5
+5 +5
6/2=2y/2
3=y
2x-4= 18
+4 +4
2x/2 = 22/2
x=11
F(x) = 3x + 5/2
f(a+2) = 3(a+2) + 5/2 = 3a+6 + 5/2
= 3a + (12+5)/2 = 3a + 17/2
