Answer:
Let me give you an example of a segment addition problem that uses three points that asks the student to solve for x but has a solution x = 20.
First, I assumed values for each x, y and z and then manipulated their coefficients to get the total at the end of each equation.
20 + 10 +30 = 60
40 + 0 + 40 = 80
40 + 10 = 50
Then exchangeing these numbers into values and we have the following equation.
x + 2y + 3z = 60
2x + 4z = 80
2x + z = 50 so its easy
If you will solve them manually by substituting their variables into these equations, you can get
x = 20
y = 5
z = 10

Answer: 0.48
Explanation:
P(A/B) = P(AnB)/P(B) where:
P(A/B) = The probability of event A occurring given that B has occurred.
P(AnB) = The probability of both events A and B occurring.
P(B) = the probability that event B occurs.
So let
P(A) = Probability that the residents of a household own 2 cars.
P(B) = Probability that the annual household income is greater than $25,000.
The question tells us that
P(A/B) = 0.8
Note that: P(A) = 0.7, P(B) = 0.6.
Since we want to work out P(AnB), because it gives the probability that residents have an annual household income over $25,000 and own 2 cars.
We would Rearrange our initial equation to make P(AnB) the subject formula becoming;
P(A/B) = P(AnB)/P(B)
P(B)*P(A/B) = P(AnB)
So, inserting our probabilities into this equation gives:
0.6*0.8 = 0.48
Answer and explanation:
Location is one of the many factors businesses must consider at the moment of starting operations. Commercial areas tend to have higher rent and property prices. Typically, businessmen deal with it by increasing their products price so they can cover expenditures and make a profit. At the same time, most consumers are willing to pay the higher price for the product because it removes the need for relocation even if it could imply moving one or two blocks away.
Answer:
8%
Explanation:
Internal rate of return is the discount rate that equates the after-tax cash flows from an investment to the amount invested
IRR can be calculated with a financial calculator
Cash flow in year 0 = $-300
Cash flow each year from year 1 to 4 = 
× $300 = $24
Cash flow in year 5 = $300 + 24 = $324
IRR = 8%
To find the IRR using a financial calculator:
1. Input the cash flow values by pressing the CF button. After inputting the value, press enter and the arrow facing a downward direction.
2. After inputting all the cash flows, press the IRR button and then press the compute button.
Answer:
(a) $500
(b) $620
(c) $180
(d) $72
Explanation:
Explicit costs refers to the which are incurred during running the business and these costs affects the profitability of the company.
Implicit costs refers to the opportunity cost of selecting some other alternative.
(a) Here, the explicit cost is the cost of purchasing materials = $500
(b) If I rent an electric saw, then the explicit cost is as follows:
= Purchasing cost of material + (Rent × No. of hours to build ramp)
= $500 + ($20 × 6 )
= $500 + $120
= $620
(c) If I use a handsaw, then the implicit cost is as follows:
= Hours to build ramp × A job pays $12 per hour
= 15 × $12
= $180
(d) If I rent an electric saw, then the implicit cost is as follows:
= Hours to build ramp × A job pays $12 per hour
= 6 × $12
= $72
