For the mortality data examined in example 2.2: (a) add another component to the regression in (2.21) that accounts for the particulate count four weeks prior; that is, add pt−4 to the regression in (2.21). state your conclusion. (b) draw a scatterplot matrix of mt, tt, pt and pt−4 and then calculate the pairwise correlations between the series. compare the relationship between mt and pt versus mt and pt−4.

hi there!

the answer will be d: 2

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
