Drag equations to each row to show why the equation of a straight line is y = 3x, where 3 is the slope.

Reason

Triangle 1 is similar to triangle 2.

Multiply both sides by x.

Statement:

What is the pattern in the values as the exponents increase?

Solve 4 ln x=2ln25 a) x=5 b) x=25 c) x=625

Researchers are conducting experiments to determine the role of alcohol in the development of depression. after the study is complete, they determine that the relative risk of developing depression is 1.55 with a 95 % ci of 1.2 -1.9. each group is then divided into nonsmokers and smokers. the relative risk for the nonsmokers is 1.12 with a 95% ci of 0.87-1.37. the relative risk for the smokers is 1.7 with a 95 % cl of 1.5-1.9. what type of bias may affect this study? a. procedure bias b. recall bias c. selection bias d. confounding e. lead-time bias
