Answer:
c= 61m
Step-by-step explanation:
using Pythagoras theorem, sin33°=a/c
sin33°=33/c
using tables, sin33°=0.5446
substituting,
0.5446=33/c
cross multiply
0.5446*c=33
divide both sides by 0.5446
c=33/0.5446
c=60.5949321
c=61m (to the nearest whole number)
(x-6.25)×1.6667×2.8=146÷5.2143
((146÷5.2143)÷(1.6667×2.8))+6.27=x
The residuals are the difference between the dataset values and the values computed from the regression formula. Here is a plot.
