The Cardiovascular Risk in Young Finns Study showed average baseline triglyceride levels among 920 people of 0.926 mmol/L associated with a total sum of squared deviations of approximately 160 mmol/L. If a linear regression analysis of baseline triglyceride levels on physical activity levels had an R-squared of 0.30, what are the sum of squared deviations explained by the regression model? a. 112 mmol/L
b. Not enough information
c. 48 mmol/L

The sum of the squared deviations explained by the regression model is:

c. 48 mmol/L

Step-by-step explanation:

Average baseline triglyceride levels among 920 people = 0.926 mmol/L

Total sum of squared deviations, approximately = 160 mmol/L

Linear regression analysis of baseline triglyceride levels on physical activity levels had an R-squared = 0.30

Therefore, the sum of the squared deviations explained by the regression model = 160 * 0.30 = 48 mmol/L

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).
