Use the formula (zy)i = (yi – ȳ) / s y and calculate a standardized value for each yi. Add the products from the last step together. Divide the sum from the previous step by n – 1, where n is the total number of points in our set of paired data. The result of all of this is the correlation coefficient r.

Solution:

The cost for Dana and Courtney's lunch is $24

They want to leave a 15% tip

To find: total cost of their lunch, including the tip

Find the tip amount

Total cost = cost of lunch + tip amount

Total cost = 24 + 3.6

Total cost = 27.6

Thus total cost of their lunch, including the tip is $ 27.6

(3) y = (x -3)²

Step-by-step explanation:

Try the first value of x in each function:

(1) y = 3² -3 ≠ 0

(2) y = (3 +3)² ≠ 0

(3) y = (3 -3)² = 0 . . . . . . matches the table value for f(3)

(4) y = 3² +3 ≠ 0

The only viable choice is (3).
