Answer:
7,15,20
Step-by-step explanation:
Triangle side rule : The sum of the two shorter sides must be greater than the length of the largest side.
7 , 15 and 20
7 + 15 must be greater than 20 in order for 7,15 and 20 to be sides of a triangle
7 + 15 = 22
22 > 20 is true so this might be the answer but lets check the other answer choices just in case.
( we do this same process to the other answer choices )
11 , 22 and 35
11 + 22 must be greater than 35 in order for these to be side lengths of a triangle
11 + 22 = 33
33 is not greater than 35 therefore these sides lengths can not represent sides of a triangle
7, 16 and 23
7 + 16 must be greater than 23
7 + 16 = 23
23 > 23 , this is not true so this can't be the answer.
5 + 17 must be greater than 22
5 + 17 = 22
22 > 22 this is not true so this can't be the answer.
The answer is 7,15,20

You are CEO of Rivet Networks, maker of ultra-high performance network cards for gaming computers, and you are considering whether to launch a new product. The product, the Killer X3000, will cost $900,000 to develop up front (year 0), and you expect revenues the first year of $800,000, growing to $1.5 million the second year, and then declining by 40% per year for the next 3 years before the product is fully obsolete. In years 1 through 5, you will have fixed costs associated with the product of $100,000 per year, and variable costs equal to 50% of revenues. what are the cash flows for the project in years 0 through 5? Plot the NPV profile for this investment from 0% to 40% in 10% increments. what is the project's NPV if the project's cost of capital is 10%? Use the NPV profile to estimate the cost of capital at which the project would become unprofitable;
The NPV of the project is $0 when the cost of capital is around 31%, and the project becomes unprofitable beyond this point.
Given data, The upfront cost of the project is $900,000Year 1 revenues
= $800,000Year
2 revenues = $1,500,000 Year
3-5 revenue decline by 40% each year Fixed costs = $100,000 per year Variable costs = 50% of revenue
Year-wise cash flows: Year 0: -$900,000 Year
1: $800,000 - 50%($800,000) - $100,000 = $300,000Year
2: $1,500,000 - 50%($1,500,000) - $100,000 = $550,000Year
3: $0.6(1 - 0.4)($1,500,000) - 50%($0.6(1 - 0.4)($1,500,000)) - $100,000
= $210,000Year

Net cash flow in years 0-5 = -$900,000 + $300,000 + $550,000 + $210,000 + $126,000 + $75,600
= $362,600.
The following is the NPV profile of the project: For the cost of capital of 10%, the project's NPV can be calculated by discounting the cash flows by the cost of capital at 10%.
NPV = -$900,000 + $300,000/(1 + 0.10) + $550,000/(1 + 0.10)2 + $210,000/(1 + 0.10)3 + $126,000/(1 + 0.10)4 + $75,600/(1 + 0.10)5

= $101,392.22
The project's NPV is $101,392.22 when the cost of capital is 10%.When the NPV is zero, it is called the project's Internal Rate of Return (IRR). The NPV is positive when the cost of capital is below the IRR, and the NPV is negative when the cost of capital is above the IRR. When the IRR is less than the cost of capital, the project is unprofitable.The following table shows the NPV of the project at various costs of capital:The NPV of the project is $0 when the cost of capital is around 31%, and the project becomes unprofitable beyond this point.

What kind of transformation converts the graph of f(x)=7x-1 into the graph of g(x)=-7x+1 ? vertical stretch reflection across the y-axis vertical shrink reflection across the x-axis
The correct answer is "reflection across the y-axis" kind of transformation converts the graph of f(x)=7x-1 into the graph of g(x)=-7x+1 .
The transformation that converts the graph of f(x) = 7x - 1 into the graph of g(x) = -7x + 1 is a reflection across the y-axis.
We can see this by comparing the two functions term by term.
f(x) = 7x - 1
g(x) = -7x + 1
To get from f(x) to g(x), we simply negate the coefficient of x in each function, which results in a reflection across the y-axis.
Therefore, the correct answer is "reflection across the y-axis".

You have 3 attempts left before new version will be requested. You have unlimited attempts remaining.
The value at which x does the tangent to the curve y=cosx have a slope of 1 is x = 3π/2.
To find the values of x at which the tangent to the curve y = cos(x) has a slope of 1, if x belongs to the interval [0,2π], we need to find the points where the derivative of the function is equal to 1. The derivative of y = cos(x) with respect to x is -sin(x). So, we need to solve the equation:
-sin(x) = 1
sin(x) = -1
Now, we want to find the values of x in the interval [0, 2π] that satisfy this equation. The sine function takes the value -1 at x = 3π/2. Therefore, x does the tangent to the curve y=cosx have a slope of 1 is x = 3π/2.

were the results of the simple and the multiple linear regression tests different? if yes, how so?
A simple linear regression model only includes one independent variable, while a multiple linear regression model includes two or more independent variables. The purpose of both models is to examine the relationship between the dependent variable and the independent variable(s) and to make predictions based on that relationship.
If the same dependent variable and independent variable(s) were used in both the simple and multiple linear regression tests, then it is possible that the results could be different. The multiple linear regression model may provide a more accurate prediction of the dependent variable since it takes into account multiple independent variables. Overall, without more information about the data and the specific models used, it is difficult to determine whether the results of the simple and multiple linear regression tests were different or not.

Use the normal approximation to find the indicated probability. The sample size is n, the population proportion of successes is p, and X is the number of successes in the sample.
n = 90, p = 0. 41: P(32 < X < 43)
The probability P(32 < X < 43) is approximately 0.691
To use the normal approximation, we need to check if the sample size is large enough for the distribution to be approximately normal.
For a binomial distribution with sample size n and probability of success p, the mean is np and the standard deviation is sqrt(np(1-p)).
In this case, the mean is 90*0.41 = 36.9 and the standard deviation is sqrt(90*0.41*0.59) = 4.43.
To find the probability P(32 < X < 43), we can standardize using the z-score formula:
z1 = (32 - 36.9)/4.43 = -1.09
z2 = (43 - 36.9)/4.43 = 1.38
Using a standard normal distribution table, we can find the area between -1.09 and 1.38, which is approximately 0.691.
Therefore, the probability P(32 < X < 43) is approximately 0.691.
Probability is the branch of mathematics concerned with measuring the likelihood or chance of events occurring. It is a way to quantify uncertainty and can be applied to a wide range of fields, including statistics, finance, and science.
The probability of an event is a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that the event is certain. If the probability of an event is 0.5, for example, it means that the event has an equal chance of occurring or not occurring.
There are two main types of probability: theoretical and experimental. Theoretical probability is based on mathematical models and calculations, while experimental probability is based on observations and experiments.
