Answer:
Step-by-step explanation:
We can use the regression line to model the linear relationship between x and y ... x and y because the correlation coefficient is not significantly different from zero. ... If r is significant and the scatter plot shows a linear trend, the line can be used to ... If r < negative critical value or r > positive critical value, then r is significant.
Actual Distance =120 Km
We have to map 120 Km in the scale of 3 Cm.
i.e, 3 Cm = 120 Km
→ 1 cm = (120÷3) Km
→ 1 cm = 40 Km
So, if you scale 3 cm on the map correspond to 120 km,then
you have to scale , 1 Cm= 40 Km
