Answer:
Explanation:
The constraints we have are two in number.
1. Sam and Kori cannot sit next to each other
2. Lynn and Kori need to sit next to each other.
Both options A and B satisfy both these constraints because Sam and Kori are seated apart and Lynn and Kori are seated together.
Option C satisfies only one constraint which is that Kori is sitting next to Lynn. She is sitting next to Sam however so this option is wrong and by extension, so is option D as well.
Answer: 20,000 lawn mowers
Explanation:
The formula for calculating the number of lawn mowers needed to reached the budgeted profit levels is:
= (Fixed costs + Budgeted profit) / Contribution margin
Contribution margin = Selling price - Variable cost
= 40 - (14 + 8 + 5)
= 40 - 27
= $13
Number of lawn-mowers required:
= (140,000 + 120,000) / 13
= 20,000 lawn mowers
Answer:
$-76,447.56
Explanation:
Net present value is the present value of after-tax cash flows from an investment less the amount invested.
NPV can be calculated using a financial calculator
Cash flow in Y0 = -630,000
Cash flow in Y1 - Y6 = 100,000
Cash flow in Y7 = 100,000 + 130,000
I = 10%
npv = $-76,447.56
To find the NPV 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 NPV button, input the value for I, press enter and the arrow facing a downward direction.
3. Press compute
Parametric estimation is a techniques that uses a statistical relationship to calculate cost or duration based on historical data and other project parameters
Parametric estimation is a quantitative method (statisitical relationship) used to estimate the project cost, resources, and duration based on historical data and other project parameters.
Parametric estimation models are used when:
- There is precedent
- The model is a unit hence can be scaled up
- The parameters required are easily quantifiable
While the other options of this question is incorrect because:
b. grass roots estimating
Cost estimation done by the individuals who will be performing the task being estimated.
c. empirical estimating
Estimation method in which the data is obtained using empirical formulas. It is usually based on an amalgamation of historical data, assumptions, guesses, and personal experience.
d. analogous estimating
Also called top-down estimating, this is a technique that involves comparing previous projects, personal experiences and cursory cross-referencing observed costs to estimate time resources required. This technique is most useful in the absence of quantifiable data.

The distribution organizes data by recording all the values observed in a sample as well as how many times each value was observed.
Data distribution is a function that provides all possible values of a variable and also quantifies their relative frequencies (probabilities of how often they occur). Distributions are considered for all populations in which the data are spread out. Another example is a pie chart showing the percentages of different substances that make up the complete object.
We divided the distributions into two categories, depending on the type of organizes data you are using. Discrete distributions for discrete data (finite results) and continuous distributions for continuous data (infinite results).
