<u>Question 10:</u>
21.75 ÷ 30 = 0.725
Move the decimal backwards 2 times
72.5
<em>Answer: </em>72.5%
<u>Question 11:</u>
Sales: $768
Commission Rate: 4%
Commission: $30.72
768 x 4 = 3,072
3,072 ÷ 100 = 30.72
<em>Answer:</em> $30.72
<u>Question 12:</u>
Selling Price: $39.98
Tax Rate: 4.5%
Sales Tax: $1.80
39.98 x 4.5 = 179.91
179.91 ÷ 100 = 1.7991
Then you round to the thousandths.
1.799
1.8
<em>Answer:</em> $1.80
<u>Question 13:</u>
20% x 141 = 28.2
141 + 28.2 = 169.2
<em>Answer:</em> $28.20 gratuity is added to the bill.

Answer:
(x +6)^2 +(y -10)^2 = 225
Step-by-step explanation:
The standard form equation for a circle is ...
(x -h)^2 + (y -k)^2 = r^2
where the center is (h, k) and the radius is r.
The center of a circle is the midpoint of any diameter. The midpoint between two points is the average of their coordinates.
((-15, -2) +(3, 22))/2 = (-15+3, -2+22)/2 = (-6, 10)
The radius can be found using the distance formula, or by simply putting one of the given points in the equation for the circle to see what the constant (r^2) needs to be.
(x -(-6))^2 +(y -10)^2 = (-15-(-6))^2 +(-2-10)^2
(x +6)^2 +(y -10)^2 = 81 +144 = 225
The equation of the circle is ...
(x +6)^2 +(y -10)^2 = 225
Answer:
Standard deviation measures Total risk while beta measures Systematic risk.
Step-by-step explanation:
The total risk is the total variability of the portfolio and includes the systematic risk and the unique risk.
The systematic risk is measured by the beta coefficient and it considers the no diversified risk such as changes in the global market. Unique risks are the ones that result from factors specifically related to the company.
