Answer:
The answer is "158.489"
Step-by-step explanation:
for san francisco earthquake:
![\log(\frac{a_1}{T}) + B = 7.8\\\\\log(\frac{a_1}{T})+\log(10^{B}) = 7.8\\\\\log(\frac{a_1}{T} \times 10^{B})=7.8\\\\(\frac{a_1}{T} \times 10^B=10^{7.8}...............(i)](https://tex.z-dn.net/?f=%5Clog%28%5Cfrac%7Ba_1%7D%7BT%7D%29%20%2B%20B%20%3D%207.8%5C%5C%5C%5C%5Clog%28%5Cfrac%7Ba_1%7D%7BT%7D%29%2B%5Clog%2810%5E%7BB%7D%29%20%3D%207.8%5C%5C%5C%5C%5Clog%28%5Cfrac%7Ba_1%7D%7BT%7D%20%5Ctimes%2010%5E%7BB%7D%29%3D7.8%5C%5C%5C%5C%28%5Cfrac%7Ba_1%7D%7BT%7D%20%5Ctimes%2010%5EB%3D10%5E%7B7.8%7D...............%28i%29)
similarly , for coloumbia earthquake:
![\frac{a_2}{T}\times 10^B = 10^{5.6}.................(ii)](https://tex.z-dn.net/?f=%5Cfrac%7Ba_2%7D%7BT%7D%5Ctimes%2010%5EB%20%3D%2010%5E%7B5.6%7D.................%28ii%29)
divide equation (i) and (ii):
![\frac{a_1}{a_2}=\frac{10^{7.8}}{10^{5.6}}\\\\\frac{a_1}{a_2}=10^{2.2}\approx 158.489](https://tex.z-dn.net/?f=%5Cfrac%7Ba_1%7D%7Ba_2%7D%3D%5Cfrac%7B10%5E%7B7.8%7D%7D%7B10%5E%7B5.6%7D%7D%5C%5C%5C%5C%5Cfrac%7Ba_1%7D%7Ba_2%7D%3D10%5E%7B2.2%7D%5Capprox%20158.489)
I would think (10,1) and (1,9) would make the most accurate line of best fit since it is surrounded by most points. Would you agree? Since the (10,0) may just be an anomaly plot.

Answer:
0.17753
Step-by-step explanation:
Although the first number has more digits, 0.17753 is greater. since the first two digits are the same you go to the hundredths place for both and compare. 7 is greater than 5, so 0.17753 is bigger.
