What is the significance of a correlation coefficient of -0.97? A. The points all lie very close to the line of fit, and the
line is decreasing.

B. The points all lie very close to the line of fit, and the
line is increasing.

C. The points do not follow the line of fit and, the line is
decreasing.

D. The points do not follow the line of fit, and the line is
increasing.

It's A. The points all lie very close to the line of fit, and the line is decreasing.

Step-by-step explanation:

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
