Answer:

40%

Step-by-step explanation:

Tanya has a a choice of 5 different routes (1-20 mins, 2-30 mins, 2-40 mins).

How many routes can she take that will take her 30-mins to get home?

The answer is 2.

What's the probability she will take 2 of the 5 routes to get home?

The probability is 2/5 so 40%.

The rounding instruction was there to mislead you in this case :-)

Complete the equation of the graphed linear function in point-slope form.
BlackZzzverrR [31]
They are using the point (2, 8) to write this equation.  You know that because of the "y-8" in the equation, and also because it's bolded! lol.  Anyways, what's missing is the slope and the x value from our point.  The slope is -2.  Find this by picking 2 points on the line and putting those into the slope equation.  Use the bolded point and the x-intercept: (2,8) and (6,0):m= \frac{0-8}{6-2}= \frac{-8}{4}=-2.  As stated earlier the x coordinate in the bolded point is 2.  So our equation is y-8=-2(x-2).  And there you Go!
