<span>d. suppose you have run the regression and afterward you want to introduce another orthogonal variable, say, xk 1 into the model. do you have to recompute all the previous coefficients 1 to k? why or why not?</span>
After thorough research, there exists the same question that ask:
<span>Based on the equation, how much more money, in millions of dollars, was earned in revenue for week 3 than for week 5?</span>
The question will give a high value but nevertheless, it is still answerable.
Function is equal to 73^x
For 3 weeks , we will get
= 73^3 - 73^2
For 5th week = 73^4 x 72
Based on the equation, it is obvious that we get more in 5th week compared to 3rd of around 2 billion.
Fifty times two plus fifteen plus two
