Which statement is not correct? multiple choice spurious correlation can often be reduced by expressing x and y in per capita terms. autocorrelation is mainly a concern when we are using time-series data. heteroscedastic residuals will have roughly the same variance for any value of x. standardized residuals make it easy to identify outliers or instances of poor fit.

yes

step-by-step explanation:

the answer is 99.

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).

tried on you are knowing that we can't leave the picture in the graph ok no problem now you need to send it in the question group
