matrenka [14]
<h2>Answer:</h2><h2>Health inspector can pick 3 restaurants of 13 restaurants on Monday in 286 ways</h2>

Step-by-step explanation:

nCr ! = \frac{n!}{r!(n-r)!}

13 C 4! = \frac{13!}{3!(10)!}

= \frac{11.12.13}{2.3}

= 286

Health inspector can pick 3 restaurants of 13 restaurants on Monday in 286 ways

How do you find the slope on a graph
podryga [215]
Remember that the slope of a line never changes, so you can choose whatever 2 points you want and you will always get the same slope. Calculate the rise and run (You can draw it on the graph if it helps). Theslope is 2/4, which , of course, you can simplify to ½.
