There are 2 students who used none of the above-mentioned means of transportation.

There were 2 students who used none of the above-mentioned means of transportation.

A poll was conducted on 100 students at a commuter campus to determine how they got to school.

The following are the results: 36 people drove alone.

34 people carpooled.30 people used public transportation.

5 people used both carpools and public transportation.8 people used both a carpool and their own car.

7 people used buses and their own cars.

4 people used all three modes of transportation.

Now, let us calculate the number of students who didn't use any of the above means of transportation:

Number of students who drove alone = 36

Number of students who carpooled = 34

Number of students who used public transport = 30

Number of students who used carpool and public transport = 5

Number of students who used carpool and their own car = 8

Number of students who used buses and their own car = 7

Number of students who used all three modes of transportation = 4

Thus, the total number of students who used one or more means of transportation =36+34+30+5+8+7+4 = 124

Now, subtracting the number of students who used one or more means of transportation from the total number of students polled will give us the number of students who used none of the means of transportation.

100 - 124 = -24

But, negative values are meaningless in this context.

Hence, the answer is 2.

Ted should charge approximately $12.80 for the peanut butter in jars that are 16 cm in diameter and 20 cm high if he wants to maintain the same price per cubic centimeter.

To determine the price for the larger jar, we need to compare the volumes of the two jars and adjust the price accordingly.

The volume of a jar can be calculated using the formula for the volume of a cylinder:

\(V = \pi r^2h\),

where V is the volume,

π is a mathematical constant approximately equal to 3.14159,

r is the radius of the base (half the diameter),

h is the height of the cylinder.

Let's calculate the volume of the smaller jar first:

\(Radius (r) = \frac{diameter }{2}\)

\(Radius (r) = \frac{8 cm }{2}\)

\(Radius (r) = 4 cm\)

\(Height (h) = 10 cm\)

\(Volume of the smaller jar = \pi (4 cm)^2 \times10 cm\)

\(Volume of the smaller jar \approx 502.65 cm^3\)

Now, let's calculate the volume of the larger jar:

\(Radius (r) = \frac{diameter }{2}\)

\(Radius (r) = \frac{16 cm}{2}\)

\(Radius (r) = 8 cm\)

\(Height (h) = 20 cm\)

\(Volume of the larger jar = \pi (8 cm)^2 \times 20 cm\)

\(Volume of the larger jar \approx 4021.24 cm^3\)

The ratio of the volumes between the larger jar and the smaller jar is approximately

\(\frac{4021.24 cm^3 }{502.65 cm^3} \approx 7.999\)

Since Ted wants to charge the same price per cubic centimeter, the price for the larger jar should be approximately 7.999 times the price of the smaller jar.

\(Price for the larger jar = $1.60 \times 7.999\)

\(Price for the larger jar \approx \$ 12.80\)

Therefore, Ted should charge approximately $12.80 for the peanut butter in jars that are 16 cm in diameter and 20 cm high if he wants to maintain the same price per cubic centimeter.

Statistical power is a measure of the ability to reject the null hypothesis when it is false. It represents the probability of correctly identifying a true effect or relationship in a statistical hypothesis test.

A high statistical power indicates a greater likelihood of detecting a significant result if the null hypothesis is indeed incorrect. The power of a statistical test depends on several factors, including the sample size, the effect size (the magnitude of the true effect or difference), the chosen significance level (often denoted as α), and the variability or noise in the data. Increasing the sample size or effect size generally increases the statistical power, while a lower significance level or higher variability decreases it.

Power analysis is commonly used to determine an appropriate sample size for a study, ensuring that it is adequately powered to detect the desired effect. A higher power is desirable as it reduces the chances of a Type II error (failing to reject the null hypothesis when it is false) and increases the chances of correctly detecting real effects or relationships.

By 15% percent does the population of weeds decrease each day given that the function representing the number of weeds is W(d)=1650(0.85)^d. This can be obtained by using the function representing the exponential decay.

Number of weeds is represented by the function,

W(d)=1650(0.85)^d

⇒ W(d)=1650(1 - 0.15)^d

Here, d = number of days since application

Function representing the exponential decay is,

⇒ A(r) = A(1 - r)^t

where,

A = Initial value

r = Percentage decay

t = duration

By comparing the given function and function representing the exponential decay,

r = 0.15 ≈ 15/100

Or r = 15%    

Therefore, population of weeds will decrease 15% each day.

Hence by 15% percent does the population of weeds decrease each day given that the function representing the number of weeds is W(d)=1650(0.85)^d.

There is a 0.0228 percent chance of getting a sample mean this big or bigger.

Given that the sample size is 64, the sample size is 3.2, and the standard deviation is 0.8.

The likelihood of a mean of 3.4 is determined as follows:

#First determine the z-value:

\(z=\frac{\bar{X}-\mu}{\sigma / \sqrt{n}}$$=\frac{3.4-3.2}{0.8 / \sqrt{64}}$$=2.000$\)

#We then determine the corresponding probability on the z tables:

\(Z(X \geq 3.4)=1-P(X < 3.4)$$=1-0.97725$$=0.0228$\)

Hence, the probability of obtaining a sample mean this large or​ larger is 0.0228.

Biblical tithing basically means you will give 10 percent of your income to the lord.The word tithe refers to "tenth" or "tenth part," so biblical tithing implies offering one-tenth of one's income to the church.

Biblical tithing is the method of giving the first fruits of one's labor to the Lord. Tithing originated from the Old Testament in which people would offer 10% of their harvest to the Lord.Tithing is a way of giving back to God as well as to others, according to the Bible.

As a result, Christians are required to tithe a tenth of their earnings. While this might appear to be a significant amount of money, if Christians can trust God with their finances, they can discover that he blesses them in ways they never imagined. In the New Testament, there is no specific requirement to tithe, but Christians are urged to give generously to the church and those in need.

Answer: 23.2  

Step-by-step explanation:

a.  The probability that this runner will complete this road race: In less than 160 minutes is 0.0764. The correct answer is C.

b.  The probability that this runner will complete this road race: In 215 to 245 minutes is 0.1125 The correct answer is C.

a. To find the probability for each scenario, we'll use the given normal distribution parameters:

Mean (μ) = 190 minutes

Standard Deviation (σ) = 21 minutes

Probability of completing the road race in less than 160 minutes:

To calculate this probability, we need to find the area under the normal distribution curve to the left of 160 minutes.

Using the z-score formula: z = (x - μ) / σ

z = (160 - 190) / 21

z ≈ -1.4286

We can then use a standard normal distribution table or statistical software to find the corresponding cumulative probability.

From the standard normal distribution table, the cumulative probability for z ≈ -1.4286 is approximately 0.0764.

Therefore, the probability of completing the road race in less than 160 minutes is approximately 0.0764. The correct answer is C.

b. Probability of completing the road race in 215 to 245 minutes:

To calculate this probability, we need to find the area under the normal distribution curve between 215 and 245 minutes.

First, we calculate the z-scores for each endpoint:

For 215 minutes:

z1 = (215 - 190) / 21

z1 ≈ 1.1905

For 245 minutes:

z2 = (245 - 190) / 21

z2 ≈ 2.6190

Next, we find the cumulative probabilities for each z-score.

From the standard normal distribution table:

The cumulative probability for z ≈ 1.1905 is approximately 0.8820.

The cumulative probability for z ≈ 2.6190 is approximately 0.9955.

To find the probability between these two z-scores, we subtract the cumulative probability at the lower z-score from the cumulative probability at the higher z-score:

Probability = 0.9955 - 0.8820

Probability ≈ 0.1125

Therefore, the probability of completing the road race in 215 to 245 minutes is approximately 0.1125. The correct answer is C.

Based on the computed 95% confidence interval, we can conclude that we are 95% confident that the true population mean falls within the range of 12.65 to 25.65.

A confidence interval is a range of values that provides an estimate of the true population parameter. In this case, we are interested in estimating the population mean (μ). The 95% confidence interval, as mentioned, is given as 12.65 ≤ μ ≤ 25.65.

Interpreting this confidence interval, we can say that if we were to repeat the sampling process many times and construct 95% confidence intervals from each sample, approximately 95% of those intervals would contain the true population mean.

The confidence level chosen, 95%, represents the probability that the interval captures the true population mean. It is a measure of the confidence or certainty we have in the estimation. However, it does not guarantee that a specific interval from a particular sample contains the true population mean.

Therefore, based on the computed 95% confidence interval, we can conclude that we are 95% confident that the true population mean falls within the range of 12.65 to 25.65.

The taxpayer who would most likely benefit from an installment sale is Allan, who sold a business use car at a net gain that was less than the amount of depreciation.

An installment sale is a transaction in which the sales price is received over a period of time that spans more than one tax year. Installment sales may have tax advantages, which is why taxpayers should consider them.

The taxable profit in an installment sale is not calculated using the entire sales price. Instead, it is calculated by applying the gross profit percentage to each installment's payments received during the year. In general, if an installment sale meets the definition, the taxpayer reports income from the sale as the payments are received, rather than in the year of sale.

However, in some situations, taxpayers might choose to report the entire profit from an installment sale in the year of sale. In such instances, an election to do so must be made.

The difference between the sales price and the adjusted cost basis of the asset is known as the gain. The gain is reduced by selling expenditures to arrive at the net gain. Net gain occurs when the sales price of a commodity is higher than its cost of acquisition and other fees or expenses related to its purchase and sale.

Depreciation is a term used in accounting and finance to describe the systematic decrease in the value of an asset over time due to wear and tear. It is an expense that lowers a company's net income and lowers the value of an asset on the balance sheet.

Hence, Allan, who sold a business use car at a net gain that was less than the amount of depreciation, will most likely benefit from an installment sale.
