The "population" consists of 72 students, 9 of whom plan to take "dance" and 63 of whom plan to take other electives.

Thus, the experimental probability that a given student from this group of 72 will take dance is 9/72.  Reduce this fraction to lowest terms.

4 children per counselor

Find the distance between the points<br><br> (1,8) and (-3,8)
Vilka [71]

Answer:

<h2>4 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  } \\

From the question we have

d =  \sqrt{ {(1 -  - 3)}^{2} +  ({8 - 8})^{2}  }  \\  =  \sqrt{ ({1 + 3})^{2} } \\  =  \sqrt{ {4}^{2} }  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  =  \sqrt{16}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

We have the final answer as

<h3>4 units</h3>

Hope this helps you
