Every computer that a business owner purchases will lose most of its value after 5 years of use. The owner plans to purchase a computer
for $2,100 and replace it after 4 years.
Part B
Method 2 of determining the computer's value is to reduce its value by 30% after each year of use.
Which function, g(n), represents the value of the computer after n years of use for Method 2?
g(n) = 0. 3n(2,100)
(b) g(n) = 0. 7n(2,100)
g(n) = 2,100(0. 3)"
g(n) = 2,100(0. 7)"
The value of the computer after n years of use is g(n)=2100(0.7)^n. (D)
Compound interest is an interest accumulated on the principal and interest together over a given time period. The interest accumulated on a principal over a period of time is also accounted under the principal. Further, the interest calculation for the next time period is on the accumulated principal value. Compound interest is the new method of calculation of interest used for all financial and business transactions across the world. The power of compounding can easily be understood, when we observe the compound interest values accumulated across successive time periods.
To determine the computer's value after n years of use, we use the depreciation formula below:
A(n) = P(1-r)ⁿ
Here, the Principal, P = $2100 and the rate, r = 30%
Substitute these values into the formula.
\(g(n) = 2100 (1-0.3)^{n} \\g(n) = 2100 (0.7)^{n}\)
Thus, the value of the computer after n years of use is g(n)=2100(0.7)^n. (D)

An employer offers a retirement program in which 7.7% of a worker's salary is deducted from their pay and deposited into an investment fund. the company then adds an additional 9% of the worker's salary to the fund. how much would an employee have deposited into their fund in the first year if their starting salary is 45,000?
According to the given statement the total deposited into the employee's fund in the first year would be $7,515.
To calculate how much would be deposited into the employee's fund in the first year, we need to add the amount deducted from the worker's salary (7.7%) and the additional contribution made by the company (9%).
Step 1:
Calculate the amount deducted from the worker's salary:
7.7% of the worker's salary = (7.7/100) * 45,000
Step 2:
Calculate the additional contribution made by the company:
9% of the worker's salary = (9/100) * 45,000
Step 3:
Add the two amounts to find the total deposited into the fund:
Total deposited into the fund = Amount deducted from the worker's salary + Additional contribution made by the company
In the first year, an employee with a starting salary of $45,000 would have $3,465 deducted from their pay and deposited into their retirement fund.
Additionally, the company would contribute $4,050 to the fund.

Suppose the demand function for a product is given by the function: D(q)=−0.018q+88.2 Find the Consumer's Surplus corresponding to q=2,750 units. (Do no rounding of results until the very end of your calculations. At that point, round to the nearest tenth, if necessary. It may help you to sketch the demand curve, which crosses the horizontal at q=4,900.) Answer: _____ dollars
The Consumer's Surplus corresponding to q=2,750 units is,
CS(2,750) ≈ 378,127.5 dollars
Now, For the consumer surplus corresponding to q=2,750 units, we'll need to find the area of the region between the demand curve and the horizontal axis, from q=0 to q=2,750.
The demand curve is given by the function D(q) = -0.018q + 88.2.
To find the price corresponding to a quantity of q, we'll need to take the derivative of D with respect to q and invert it:
D(q) = -0.018q + 88.2
dD/dq = -0.018
1/(dD/dq) = -55.56
So the price corresponding to a quantity of q is given by,
P(q) = -0.018q + 88.2.
At a quantity of q=2,750, the price is:
P(2,750) = -0.018(2,750) + 88.2 = 38.2
The consumer surplus corresponding to a quantity of q=2,750 can be found as follows:
CS(2,750) = ∫[0,2,750] (P(qmax) - P(q)) dq
where q(max) is the quantity at which the demand curve intersects the horizontal axis.
From the problem statement, we know that this occurs at q=4,900.
CS(2,750) = ∫[0,2,750] (P(4,900) - P(q)) dq
= ∫[0,2,750] (49.482 - (-0.018q + 88.2))
dq = ∫[0,2,750] (137.682 + 0.018q)
dq = [137.682q + 0.009q²]₀²,750
= 378,127.5
Rounding to the nearest tenth, we get:
CS(2,750) ≈ 378,127.5 dollars

Suppose the alternative hypothesis of this test had been lower-tailed instead of two-tailed. How would this affect the conclusions of this test?
a. Unlike the two-tailed test, we would conclude that there is a difference between Pharaoh's translation and the translation of the other software.
b. Unlike the two-tailed test, we would conclude that there is no difference between Pharaoh's translation and the translation of the other software.
c. The results of a lower-tailed test are always opposite the results of a two-tailed test, so we would fail to reject the null hypothesis.
d. The conclusion would be the same as the two-tailed test. Although the p-value for the lower-tailed test is different, it is still less than alpha.
e. The conclusion would be the same as the two-tailed test. Although the p-value for the lower-tailed test is the same as the p-value for the two-sided test.
Option A. If the alternative hypothesis of the test had been lower-tailed instead of two-tailed, the conclusion of the test would be different.
Recall that a two-tailed test is used when the alternative hypothesis is that the population parameter is different from the null hypothesis value in any direction, while a lower-tailed test is used when the alternative hypothesis is that the population parameter is less than the null hypothesis value.
In the given scenario, if the alternative hypothesis of the test had been lower-tailed instead of two-tailed, we would have tested the following null and alternative hypotheses:
H0: Pharaoh's translation is not worse than the other software's translation.
Ha: Pharaoh's translation is better than the other software's translation.
In this case, we would have calculated the p-value for the lower tail of the sampling distribution, and compared it to the significance level alpha. If the p-value is less than alpha, we would reject the null hypothesis and conclude that Pharaoh's translation is better than the other software's translation. If the p-value is greater than alpha, we would fail to reject the null hypothesis and conclude that there is not enough evidence to suggest that Pharaoh's translation is better than the other software's translation.
Therefore, the correct answer to the question is option A: Unlike the two-tailed test, we would conclude that there is a difference between Pharaoh's translation and the translation of the other software.

a prism and a cone have the same base area and the same height. the volume of the prism is 1. what is the volume of the cone?
The volume of the cone is 1/3.
If a prism and a cone have the same base area and the same height, we can use the formula for the volume of each shape to find the volume of the cone.
The volume of a prism is given by V_prism = base area × height. Since the volume of the prism is given as 1, we can write:
1 = base area × height
The volume of a cone is given by V_cone = (1/3) × base area × height. Since the base area and the height are the same as the prism, we can substitute them into the formula:
V_cone = (1/3) × base area × height = (1/3) × 1 = 1/3
Therefore, the volume of the cone is 1/3.

for infinity car wash, the arrival rate is 9 / hour and the service rate is 16 / hour. the arrival and service distributions are not known so we can't use the m/m/1 formulas. if the average waiting time in the line is 23 minutes, then how many customers (waiting and being served) are at the carwash
The approximate number of customers (waiting and being served) at the carwash is 3.
To determine the number of customers (waiting and being served) at the carwash, we can use Little's Law, which states that the average number of customers in a system is equal to the average arrival rate multiplied by the average time spent in the system.
In this case, the average arrival rate is 9 customers per hour, and the average waiting time is given as 23 minutes (which is equivalent to 23/60 = 0.3833 hours).
Using Little's Law, we can calculate the average number of customers in the system:
Average number of customers = Average arrival rate * Average time spent in the system
Average number of customers = 9 customers/hour * 0.3833 hours
Average number of customers = 3.4497 customers
Since we can't have fractional customers, we round the value to the nearest whole number.
Therefore, the approximate number of customers (waiting and being served) at the carwash is 3.
It's important to note that this calculation assumes steady-state conditions and that the arrival and service distributions are not known.

The flag has a circle in the center, a crescent moon inside the circle, and a star inside the crecen moon Complete each scale with the value that makes it equivalent to the scale of 1 to 2,000
Answer:
See attachment 2
Step-by-step explanation:
See attachment 1 for complete question
\(Scale= 1 : 2000\)
Required
Fill in the table
The scale implies that:
To fill in the gaps of actual measurements, we simply multiply the scale measurement by 2000
To fill in the gaps of scalar measurements, we simply divide the actual measurement by 2000
For the flag height, we have:
\(Scale\ Measurement = 13.2\ cm\)
Using the analysis above:
\(Actual = 2000 * 13.2\ cm\)
\(Actual = 26400\ cm\)
Convert to meters
\(Actual = 26400m/100\)
\(Actual = 264m\)
For the flag length, we have:
\(Actual\ Measurement = 396\ m\)
Using the analysis above:
\(Scale\ Measurement = 396\ m /2000\)
\(Scale\ Measurement = 0.198\ m\)
Convert to centimeters
\(Scale\ Measurement = 0.198\ cm * 100\)
\(Scale\ Measurement = 19.8\ cm\)
For the height of crescent moon, we have:
\(Actual\ Measurement = 99\ m\)
Using the analysis above:
\(Scale\ Measurement = 99\ m /2000\)
\(Scale\ Measurement = 0.0495\ m\)
Convert to centimeters
\(Scale\ Measurement = 0.0495\ cm * 100\)
\(Scale\ Measurement = 4.95\ cm\)

A CD manufacturer wanted to determine which of two different cover designs for a newly released CD will generate more sales. The manufacturer chose 70 stores to sell the CD. Thirty-five of these stores were randomly assigned to sell CDs with one of the cover designs and the other 35 were assigned to sell the CDs with the other cover design. The manufacturer recorded the number of CDs sold at each of the stores and found a significant difference between the mean number of CDs sold for the two cover designs. Which of the following gives the conclusion that should be made based on the results and provides the best explanation for the conclusion?
A. It is NOT reasonable to conclude that the difference in sales was caused by the different cover designs because this was not an experiment.
B. It is NOT reasonable to conclude that the difference in sales was caused the different cover designs because there was no control group for comparison.
C. It is NOT reasonable to conclude that the difference in sales was caused the different cover designs because the 70 stores were not randomly chosen.
D. It is reasonable to conclude that the difference in sales was caused by the different cover designs because the cover designs were randomly assigned to stores.
E. It is reasonable to conclude that the difference in sales was caused by the different cover designs because the sample size was large.
Answer:
The statement that gives the best conclusion that should be made based on the results and provides the best explanation for the conclusion is option D;
D. It is reasonable to conclude that the difference in sales was caused by the different cover designs because the cover designs were randomly assigned to stores
Step-by-step explanation:
The data given in the question are presented as follows;
The particulars the CD manufacturer wants to determine = The CD cover design that will generate more sales
The mode of selection of the stores for the test = Random selection
The number of stores in each group of stores, n = 35 stores
The number of sets of stores tested = 2 sets of stores
Let \(\overline x_1\) represent the mean number CDs sold at one set of stores and \(\overline x_2\) represent the mean number CDs sold at the other set of stores
The null hypothesis, H₀; \(\overline x_1\) = \(\overline x_2\)
The alternative hypothesis, H₀; \(\overline x_1\) ≠ \(\overline x_2\)
Given that the statistical analysis shows that the difference in mean between the two sets of randomly selected stores is significant, we therefore should reject the null hypothesis and accept the alternative hypothesis that there is a significant difference in CD sale attributable to the difference in cover design as the CDs having on of two cover design where assigned randomly to the stores.

how to know if a function has a vertical asymptote
To determine if a function has a vertical asymptote, you need to consider its behavior as the input approaches certain values.
A vertical asymptote occurs when the function approaches positive or negative infinity as the input approaches a specific value. Here's how you can determine if a function has a vertical asymptote:
Check for restrictions in the domain: Look for values of the input variable where the function is undefined or has a division by zero. These can indicate potential vertical asymptotes.
Evaluate the limit as the input approaches the suspected values: Calculate the limit of the function as the input approaches the suspected values from both sides (approaching from the left and right). If the limit approaches positive or negative infinity, a vertical asymptote exists at that value.
For example, if a rational function has a denominator that becomes zero at a certain value, such as x = 2, evaluate the limits of the function as x approaches 2 from the left and right. If the limits are positive or negative infinity, then there is a vertical asymptote at x = 2.
In summary, to determine if a function has a vertical asymptote, check for restrictions in the domain and evaluate the limits as the input approaches suspected values. If the limits approach positive or negative infinity, there is a vertical asymptote at that value.

suppose that iq scores have a bell-shaped distribution with a mean of 101 and a standard deviation of 12 . using the empirical rule, what percentage of iq scores are at least 77 ? please do not round your answer.
Using the empirical rule, we can determine that approximately 15.87% of IQ scores are at least 77.
According to the empirical rule, for a bell-shaped distribution, approximately 68% of the data falls within one standard deviation of the mean, 95% falls within two standard deviations, and 99.7% falls within three standard deviations.
To find the percentage of IQ scores that are at least 77, we need to calculate the z-score for 77 using the formula: z = (x - μ) / σ, where x is the value, μ is the mean, and σ is the standard deviation.
z = (77 - 101) / 12 = -24 / 12 = -2
Since 77 is 2 standard deviations below the mean, we know that approximately 95% - 2% = 15.87% of the IQ scores will be at least 77. Therefore, approximately 15.87% of IQ scores are at least 77, based on the empirical rule.
