Use the Birthweight_Smoking data set introduced in Empirical Exercise E5.3 to answer the following questions. To begin, run three regressions: Birthweight on Smoker Birthweight on Smoker, Alcohol, and Nprevist Birthweight on Smoker, Alcohol, Nprevist, and Unmarried What is the value of the estimated effect of smoking on birth weight in each of the regressions

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>

answer: it's a

step-by-step explanation:

900 degrees

step-by-step explanation:

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
