Answer:

15.25

Step-by-step explanation:

The probability of getting a question right is 1/4 because there are 4 possible answers, and you're just guessing randomly.

You can expect to get 1/4 of the questions right.

\frac{1}{4}\times 61 =15.25

How would we rewrite the equation of y = 1/3x -10 if we moved its graph down six units?
levacccp [35]

6 less.  The equation of the new line would be ...
