Answer:
its 11
Step-by-step explanation:
the mode is the difference between the highest and lowest date input
19-8=11
9.
2x+3+x+9 = 180 => 3x = 168 => x = 56;
m(<ABD) = 2*56 + 3 = 115.
Answer:
B
Step-by-step explanation:
5^9•5^9/10•5^6/100•5^9/1000 = 5^(9+0.9+0.06+0.009) = 5^9.969
2/14= 1/7
I just graphed them then did the slope which was rise over run
