The step that is not used when constructing an inscribed equilateral triangle using technology is " create another circle with the same radius as the original".
What is inscribed triangle ?"The definition of circumscribed means that an object is drawn around another, making it bounded or limited within a certain boundary. And so, a circumscribed circle of a triangle is a circle that limits a triangle's space. In other words, the circle contains a triangle inside it. The vertices of the triangle are located along the boundary of the circle.
Geometric scenarios like this wherein a shape are drawn inside another or containing another; the name is given depending on which object is taken as a reference. Circumscribed circle of a triangle, the circle is outside the triangle in a simpler sense. In other words, the triangle is inside the circle."

four percent of the customers of a mortgage company default on their payments. a sample of 20 customers is selected. what is the probability that exactly two customers in the sample will default on their payments?
Answers
Using the Binomial probability distribution,
The probability that exactly two customers in the sample will default on their payments is 0.31..
We have given that,
4% of total customers a mortgage company default on their payments .
The probability of success i.e number of customers default on their payments (p) = 4%
= 0.04
The probability of failure (q) = 1-p = 1-0.04 = 0.06
Total number of customers in sample (n) = 20
we have to find out the probability that exactly two customers in the sample will default on their payments.
Using the Binomial probability distribution,
P(X=x)= ⁿCₓ(p)ˣ(q)⁽ⁿ⁻ˣ⁾
the required probability is P(X= 2 )
Now, P(X= 2) = ²⁰C₂(0.04)²(0.06)¹⁸
=> P(X=2) = 190 × 0.0016 × 1.0155 = 0.31

2. Ravi purchased an old house for Rs. 76.5000 and
spent Rs. 115000 on its. Then he sold it at a
gain of 5%. How many
much did he get.
Answers
Answer:
Rs. 924000.
Step-by-step explanation:
Cost of house = 765000
Additional money spent on it = 115000
Total cost incurred by Ravi = 765000 + 115000 = 880000
Gain = 5% of total cost
gain in Rs = 5/100 * 880000 = Rs. 44000
Total selling price of house = total cost incurred + profit = 880000+ 44000
Total selling price of house = Rs. 924000
Thus, Ravi got Rs. 924000.

Answers
When estimating the cash flows on a given project, firms should include expenses from previous years, such as research & development costs. (True)
When estimating cash flows for a project, it is important to consider all relevant expenses, including those incurred in previous years. Research and development (R&D) costs are often incurred over an extended period before a project reaches the commercialization stage. Including these expenses in the cash flow estimation provides a more accurate picture of the project's financial performance. R&D costs can be significant and have a direct impact on the project's profitability.
By including these expenses, firms can evaluate the true costs and potential returns associated with the project. Additionally, including past expenses helps in assessing the project's historical performance and provides valuable insights for decision-making.

the speed of the boat in still water was 10 miles per hour. the boat could could go 78 miles down the lazy river in the same time it took to go 42 miles up the lazy river. how fast did the current flow in the lazy river?
Answers
The speed of the current is 3 miles per hour. Answer: The speed of the current is 3 miles per hour.
.Let "t" be the time taken to travel 78 miles downstream and "t" be the time taken to travel 42 miles upstream.
The distance traveled downstream is 78 miles, so we can write:78 = (10 + x)t ... equation (1)
The distance traveled upstream is 42 miles, so we can write:42 = (10 - x)t ... equation (2)
Solving equations (1) and (2) for "t", we get:t = 78 / (10 + x) ... equation (3)
t = 42 / (10 - x) ... equation (4)
We can equate the value of "t" from equations (3) and (4) since the time is the same.
We get:78 / (10 + x) = 42 / (10 - x)
Multiplying both sides by (10 + x)(10 - x), we get:78(10 - x) = 42(10 + x)
Simplifying, we get:780 - 78x = 420 + 42x
Adding 78x and subtracting 420 from both sides, we get:120x = 360x = 3
Therefore, the speed of the current is 3 miles per hour. Answer: The speed of the current is 3 miles per hour.

find the surface area of that part of the plane that lies inside the elliptic cylinder
Answers
The surface area of that part of the plane 10x+7y+z=4 that lies inside the elliptic cylinder \(\frac{x^2}{25} +\frac{y^2}{9}\) is 15π√150 and this can be determined by using the given data.
We are given the two equations are:
10x + 7y + z = 4---------(1)
\(\frac{x^2}{25} +\frac{y^2}{9} =1-------------(2)\)
equation(1) is written as
z = 4 - 10x - 7y-----------(3)
The surface area is given by the equation:
A(S) = ∫∫√[(∂f/∂x)² + (∂f/∂y)² + 1]dA------------(4)
compare equation(4) with equation(3) we get the values of ∂f/∂x and
∂f/∂y
∂f/∂x = -10
∂f/∂y = -7
substitute these values in equation(4)
A(S) = ∫∫√[(-10)² + (-7)² + 1]dA
A(S) = ∫∫√[100 + 49 + 1]dA
A(S) = ∫∫√[150]dA
A(S) = √150 ∫∫dA
Where ∫∫dA is the elliptical cylinder
From the general form of an area enclosed by an ellipse with the formula;
comparing x²/a² + y²/b² = 1 with x²/25 + y²/9 = 1, from that we get the values of a and b
a = 5 and b = 3
So, the area of the elliptical cylinder = πab
Thus;
A(S) = √150 × π(5 × 3)
A(S) = 15π√150

Answer:
Use the equation 500x0.04x20 and then 500x20 and add the sums up and get 10,400 i believe is im wrong sorry :/
$900 is the total amount of money she has after 20 years.
What is simple interest?Simple interest is, by definition, the amount of interest paid on a specific principal sum of money when an interest rate is applied. Compound interest, on the other hand, is the interest that is computed using both the principal and the interest that has accumulated over the preceding period.
From the formula of simple interest A = P(1 + rt)
Where A = amount earned
P = principal amount
r = rate of interest
t = time
In our case
P = 500
r = 4%
t = 20
Thus,
Amount earned after 20 years = 500(1 + 4*20/100)
Amount earned after 20 years = 500(1 + 4/5)
Amount earned after 20 years = 900
therefore, the total amount of money she has after 20 years is $900.

Prove that Expected Utility Theory cannot account for the preference. Note: you can assume that the initial endowment is $0 and the utility of $0 is zero.
Answers
Thus, even if the expected value of option A is higher than the expected value of option B, EUT cannot account for the preference.
Expected Utility Theory (EUT) asserts that a decision-maker's utility function can be used to predict their preferences between uncertain options.
If a decision-maker has an ordered preference ranking of lotteries, according to EUT, these rankings would correspond to their expected utility rankings.
Nevertheless, some examples demonstrate that EUT may fail to predict preferences. Let's denote a lottery as
(X₁, P₁; X2, P2; ; Xm, Pm),
where Xi and Pi indicate the reward magnitude and probability of each potential outcome.
A decision-maker prefers B ($5000, 1.00) to
A = ($0, 0.01; $25000, 0.04; $5000, 0.95) and prefers
C = ($25000, 0.04; $0, 0.96) to
D = ($5000, 0.05; $0, 0.95).
However, EUT cannot account for these preferences.
The utility of the three alternatives is calculated as follows:
U(B) = $5000
U(C) = 0.04 × $25,000 + 0.96 × $0 = $1,000
U(D) = 0.05 × $5000 + 0.95 × $0 = $250
However, the expected utilities of A and B cannot be compared.
These preferences might instead be clarified using theories like Rank-Dependent Expected Utility Theory.

(a) Find the denity for X. (b) Find E[X] and Var X. (c) Set up the calculation needed to find P[X ? 3]. (d) Ue the binomial table to approximate P[X ? 3]
Answers
(a) The distribution of X is binomial with parameters n = 20 and p = 600/3000 = 1/5 since we are randomly selecting 20 clients without replacement and interested in the proportion of happy consumers. Given below is the probability density function for this binomial distribution.
f(x) is equal to (n pick x) * p * x * (1-p) (n-x)
Where p and 1-p are the probability of success and failure, respectively, and n pick x is the binomial coefficient, which is equal to n!/(x! * (n-x)!).
(b) The formula for the anticipated value of X, or E[X], is
E[X] = np = 20 * (1/5) = 4
Var X, the variance of X, is defined as follows:
Var X = np(1-p) = 20*1/5*4/5=3.2
(c) The cumulative distribution function of the binomial distribution's formula can be used to get P[X >= 3]:
Sum(i=3 to n) f for P[X >= 3] (i)
Summarizing from I = 3 to 20 and substituting the values from the density function, we obtain:
Sum(i=3 to 20) = P[X >= 3] [(20 pick I (1/5)*i*4/5*(20-i)]
(d) We must determine the value of the cumulative distribution function at x = 3, which is equivalent to the likelihood of receiving three or fewer successes out of 20 trials, in order to approximate P[X >= 3] using the binomial table. By using n = 20 and p = 1/5 to calculate the value of the cumulative distribution function at x = 3 in the binomial table, it is possible to determine this probability. P[X >= 3]'s estimated value is 0.586.

How do drivers react to sudden large increases in the price of gasoline? To help answer the question, a statistician recorded the speed of cars as they passed a large service station. He recorded the speeds (mph) in the same location after the service station showed that the price of gasoline had risen by 15 cents. Can we conclude that the speeds differ?
Answers
Based on the information provided, we cannot conclusively determine how drivers react to sudden large increases in the price of gasoline. However, we can use the recorded speeds of cars passing the service station before and after the price increase to determine if there is a statistically significant difference in speeds.
A hypothesis test can be conducted to determine if there is a significant difference in means between the two groups. If the p-value is less than the significance level, we can conclude that the speeds differ and suggest that the price increase had an impact on driver behavior. However, if the p-value is greater than the significance level, we cannot conclude that there is a significant difference in speeds and suggest that other factors may have influenced driver behavior.
To determine how drivers react to sudden large increases in the price of gasoline, we can follow these steps:
1. Collect data: The statistician recorded the speeds (mph) of cars passing a large service station before and after the price of gasoline increased by 15 cents.
2. Analyze the data: Compare the recorded speeds before and after the price increase to see if there's a noticeable difference.
3. Conduct a hypothesis test: Perform a statistical test to determine if the observed differences in speeds are significant or due to chance. For example, you can use a paired t-test or another appropriate test based on the data collected.
4. Draw conclusions: If the test shows a significant difference in speeds, we can conclude that drivers' behavior changed in response to the price increase. Otherwise, we cannot confidently say that the speeds differ due to the price increase.
By following these steps, you can determine if drivers' speeds differ as a result of sudden large increases in the price of gasoline.
