Using the graph below, what is the best estimate of the hourly rate a person earns for 5 years of experience if the equation for the line of best fit is y= 1.3x +5.5? hourly rate ($) years of experience a. $13.00/hr b. $12.00/hr c. $10.50/hr d. $12.50/hr

B

Step-by-step explanation:

x is the number of years of experience.

In the graph, the point (y) is not shown for 5 years of experience but we can easly figure this out by plugging in 5 into x of the equation of best fit given.

Hence

So, the best estimate is $12 per hour, the correct answer is B

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
