Which of the following statements about the linear least squares model is FALSE? a) The population correlation R can measure both the direction and the strength of the linear association between two quantitative variables. b) When we construct the confidence interval for the population slope B. we should always check if our sample is random c) The point (X.) must lie on the regression line, where x is the sample mean of the explanatory variable and V is the sample mean of the response variable. d) If all points fall exactly on a straight line, then the sample correlation r must be 1.

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.

"a" determine whether sage found the correct quotient. show your work

step-by-step explanation:

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
