The two square roots of 50 will do that.
They are irrational numbers, so I can't write down their exact values.
They are approximately +7.0711 and -7.0711 (rounded) .
Solution:
<u>We know that:</u>



<u>Simplify the equation to find the percent off:</u>

This means that the <u>original price</u> has decreased about 16%.
Answer:
1. 180-(46+14)=120
2.46+14+120=180
Step-by-step explanation:
Using the mean concept, it is found that the mean difference between the call times and the company's average call time is given by:
<h3>What is the mean?</h3>
- The <em>mean </em>of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.
In this problem:
- The four observations are the differences between the time of each phone call and the average time.
- They are: {-2.32, -1.55, 4.79, 0.68}
Hence, the mean difference is:

Hence, option C is correct.
