The lsrl after an exponential transformation is log yhat=.4785 + 1.468x. What is the exponential form of the regression?
zheka24 [161]

Answer:

10^{0.4785+1.468x}=y

Step-by-step explanation:

So I'm assuming when you typed "log yhat=.4785 + 1.468x", you meant to write: log(y)=0.4785+1.468x. And generally a logarithm can be written in the form log_ba=c which can then be rewritten as b^c=a, but since the log has no base, it's assumed to be 10. So in this case you have the equation:

log_{10}y=0.4785+1.468x, which can then be written in exponential form as:

10^{0.4785+1.468x}=y

Is 50 a perfect square ? Explain your answer please 
xeze [42]
No, 50 is not a perfect square.  A perfect square is any number that can be divided by any number to get the quotient as the same number AND the quotient must be rational.  When you divide 50 so that the quotient equals the divisor, you will get an irrational number.  Therefore, 50 is not a perfect square.
