Step-by-step explanation:
We have given ,
and SP =30
We have to find the slope for regression on Y from X
The slope on Y from X is given by
As we have given the value of SP =30 and value of
So slope for regression will be
We can use the tangent rule for this problem because the opposite x is unknown and adjacent side 10 is knwon. Since,
Since tan 35°=0.474
Multiplying each sides by 10.
4.74=x
x=4.7 (Rounded to nearest tenth)
