Using the dataset HPRICE2.data, the following questions were estimated. A) Provide the mean and standard deviation of all the variables in the dataset. B) Draw a scatter plot of the variables price, nox and dist against each other. C) What is the correlation between median housing prices and nitrous oxide parts.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
