A horizontal line goes from left to right on a graph. If a line is horizontal that means that all the values of y will be the same no matter what the x is. In this case all the y - values of this graph will be 9. This makes the equation of the line:

y = 9

Hope this helped!

Expand can mean "To stretch or unfold." How can this definition help you remember this definition

There are several examples that can help one remember the definition of expand. To begin with, a balloon can expand when air or water enters it, depending on the type. Cookies often expand when baking due to the leavening agent used in the recipe. When we stretch our bodies, our muscles often expand.

(a) Count the number of ways to select a sample of 3 people to serve on a board of directors from a population of 6 people______

ValentinkaMS [17]

Answer:

(a) 20 ways

(b) 0.05 or 5%

Step-by-step explanation:

(a) Assuming that the order in which people are chosen does not matter, the number of ways to select 3 people out of possible 6 is given by the following combination.

$n=\frac{6!}{(6-3)!3!}=\frac{6*5*4}{3*2*1}=20\ ways$

(b) In a random sampling procedure, every outcome is just as likely to occur. Therefore, the chances that any particular sample will be the one selected are:

$C = \frac{1}{20}=0.05 = 5\%$
