a company has 2 photocopy machines. The probability that machine A will break down on a given day is 2%. The probability that ma
sleet_krkn [62]
Answer: 0.05%

-------------------------------------------

Work Shown:

To go from percent form to decimal form, move the decimal over 2 spots to the left. Think of 2% as 2.0%
2% = 0.02
2.5% = 0.025

Multiply the decimal form of each percentage
0.02*0.025 = 0.0005

Convert that result to a percentage. Move the decimal 2 spots to the right
0.0005 = 0.05% is the probability both break down

Note: This multiplication rule only works if the two events are independent.

Q1: Rearranging the last of the offered equations, you find

... selling price = overhead/(overhead percent) = $65.34/0.45 = $145.20

Then the net profit is

... net profit = selling price - cost - overhead = $145.20 - 49.32 - 65.34 = $30.54

Q2: Using the same net profit equation, you have

... net profit = selling price - cost - 0.47×selling price = 0.53×selling price - cost

... net profit = 0.53×$3,816,981.10 - 1,723,000.00 = $300,000

Q3: The applicable equation is

... net profit = markup - overhead

This matches selection ...

... B) Net Profit = $30.00 - 0.4 X Selling Price

Absolute value of  -4-√2i = -4-i√2,  comparing x = -4, y= -√2
<span>         
Absolute value = </span>√( (-4)² + (-√2)²),        
             
                    (-4)² = (-4)*(-4) = 16,  (-√2)² = -√2 * -√2 = 2
<span> 
                         = </span><span>√( (-4)² + (-√2)²)
</span><span>
                         </span>= √(16 + 4) = √20

√20 = √(4*5) = √4 * √5 = 2√5

Absolute value = <span>2√5</span>
