Frank is a professional golfer, so he goes to the golf course to practice every 2 days. Jack just
started playing golf, so he goes to the golf course every 6 days. Ethan just plays for fun and
goes to the golf course every 9 days. If Frank, Jack and Ethan all played together today, how
many days later will they all go to the golf course together again?

Answer:

0.5

\(points \: of \: best \: fit \: are \\ (9, 5) \: and \: (1, 1) \\ slope = \frac{(1 - 5)}{(1 - 9)} \\ = \frac{ - 4}{ - 8} \\ = \frac{1}{2} \\ = 0.5\)

70

f(-4)=5(2-3(-4)

f(-4)=10+60

f(-4)=70

The closest option is D. $-0

To determine the gain or loss on the repurchase of stock, we need to compare the repurchase price with the original sale price.

Original sale price: 500,000 shares * $50 per share = $25,000,000

Repurchase price: 12,000 shares * $40 per share = $480,000

To calculate the gain or loss, we subtract the repurchase price from the original sale price:

Gain or Loss = Original Sale Price - Repurchase Price

            = $25,000,000 - $480,000

            = $24,520,000

Since the result is a positive value, it represents a gain. Therefore, the company will recognize a gain of $24,520,000 on its income statement.

The given options do not include this exact amount, so the closest option is D. $-0-. However, it is important to note that the gain is not zero but rather $24,520,000.

The time that it take to knit the scarf from start to finish is 10 hours.

From the information, the volunteer knits a 5-foot long scarf at a constant rate and after 4 hours, the volunteer still has to knit 3 feet of the scarf.

Therefore, the volunteer used 4 hours to knit 2 scarf. The time used per scarf is 4/2 = 2 hours.

In this case, the time taken to finish the scarf will be:

= Time per feet × Total feet

= 2 × 5

= 10 hours.

A person who does not ignore a sunk cost increases the probability of making irrational decisions. This is because they are more likely to continue investing time, money, or effort into a project or situation that is not yielding positive results.

When we refer to a "sunk cost," we mean a cost that has already been incurred and cannot be recovered. Ignoring a sunk cost means not taking it into consideration when making decisions about the future. By not ignoring a sunk cost, individuals may feel a psychological attachment to their past investment, leading them to continue investing in something that may not be beneficial.

This can result in irrational decision-making and potentially wasting additional resources. For example, imagine a person who has spent a significant amount of money on a gym membership but rarely goes to the gym. Instead of accepting the fact that the money is already spent and may not be recouped.

They may feel compelled to continue paying for the membership in the hopes of eventually utilizing it. This decision is influenced by their failure to ignore the sunk cost and assess the situation rationally.

The equation of the line that is parallel to 2x + 3y = 6 is

y = (-2/3)x + b (where b is the y-intercept)

To find the equation of the line that is parallel to 2x + 3y = 6,

we first need to convert it into slope-intercept form y = mx + b

where m is the slope of the line.

2x + 3y = 6

First, we'll subtract 2x from both sides of the equation.

2x - 2x + 3y = -2x + 6

Simplify by combining like terms on the left-hand side of the equation

3y = -2x + 6

Next, we'll divide both sides of the equation by 3.

y = (-2/3)x + 2/3

The slope of the line is -2/3.

Therefore, any line that is parallel to this line will have the same slope.

The equation of the line that is parallel to the line described by 2x + 3y = 6 and passing through (-2, -3) is 3y + 2x + 13 = 0

First, we shall determine the slope of line. Details below:

2x + 3y = 6

Make y the subject

3y = -2x + 6

y = (-2/3)x + 2

Now, Comparing y = mx + c with y = (-2/3)x + 2

The slope (m₁) = -2/3

Recall,

The slope of parallel lines are equal.

Thus, we have:

m₂ = m₁ = -2/3

Finally, we shall obtain the equation of the line. Details below:

y - y₁ = m₂(x - x₁)

y - (-3) = -2/3(x - -2)

y + 3 = -2/3(x + 2)

Clear bracket

y + 3 = (-2/3)x - 4/3

Multiply through by 3

3y + 9 = -2x - 4

Rearrange

3y + 2x + 9 + 4 = 0

3y + 2x + 13 = 0

Thus, the equation of line is 3y + 2x + 13 = 0

Step-by-step explanation:

The predicted cost for a student attending a arts college with 1,500 students and a rank of 4.5 can be calculated using the given regression model: Tuition = 7 + 4*Rank - 0.20*Size + 8*Private - 0.4*LibArts.

In this case, Rank = 4.5, Size = 1.5 (since it's measured in 1,000s), Private = 1 (since it's a private college), and LibArts = 1 (since it's a liberal arts college). Plugging these values into the model, the predicted tuition cost would be: Tuition = 7 + 4*(4.5) - 0.20*(1.5) + 8*1 - 0.4*1 = $26.1 thousand.

If the student switches from her current private liberal arts college to a public, non-liberal arts college with a rank 0.5 lower and 15,000 more students, we need to adjust the Size and Rank variables accordingly. Assuming the student's current college is still private, the new values would be Rank = 4.5 - 0.5 = 4 and Size = 1.5 + 15 = 16.5 (since it's measured in 1,000s). With the new values, we can calculate the predicted tuition cost for the public college: Tuition = 7 + 4*(4) - 0.20*(16.5) + 8*0 - 0.4*0 = $22.4 thousand.

To determine how much money the student saves in tuition, we calculate the difference between the predicted costs of the two colleges: $26.1 thousand - $22.4 thousand = $3.7 thousand. Therefore, by switching from her current private liberal arts college to a public, non-liberal arts college with a lower rank and larger size, the student saves $3.7 thousand in tuition.

Using the z-distribution, it is found that the data provides convincing evidence that the proportion has increased.

At the null hypotheses, it is tested if the proportion has not increased, that is, the difference of the 2017 proportion and the 2014 proportions is not positive, hence:

\(H_0: p_2 - p_1 \leq 0\)

At the alternative hypothesis, it is tested if the proportion has increased, hence:

\(H_1: p_2 - p_1 > 0\)

For each sample, they are given by:

\(p_1 = 0.197, s_1 = \sqrt{\frac{0.197(0.803)}{61}} = 0.0509\)

\(p_2 = 0.383, s_2 = \sqrt{\frac{0.385(0.615)}{52}} = 0.0675\)

Hence, for the distribution of differences, they are given by:

\(\overline{p} = p_2 - p_1 = 0.383 - 0.197 = 0.186\)

\(s = \sqrt{s_1^2 + s_2^2} = \sqrt{0.0509^2 + 0.0675^2} = 0.0845\)

It is given by:

\(z = \frac{\overline{p} - p}{s}\)

In which p = 0 is the value tested at the null hypothesis.

Hence:

\(z = \frac{\overline{p} - p}{s}\)

\(z = \frac{0.186 - 0}{0.0845}\)

z = 2.2

Considering a right-tailed test, as we are testing if the proportion is higher than a value, the critical value at the 0.05 significance level is \(z^{\ast} = 1.645\).

Since the test statistic is greater than the critical value for the left tailed test, the data provides convincing evidence that the proportion has increased.

There are 5 pairs of whole numbers with a geometric mean of 6.

What is geometric mean?

The geometric mean is a type of average used to calculate the central tendency of a set of numbers, where the values are multiplied together and then the nth root of the product is taken, where n is the total number of values in the set.

Let's consider two whole numbers, a and b, with a geometric mean of 6. The geometric mean is defined as the square root of the product of the numbers, so we have:

√(ab) = 6

Squaring both sides of the equation, we get:

ab = 36

We want to find all pairs of whole numbers (a, b) that satisfy this equation. Since 36 has prime factorization 2² * 3², the only possible pairs of whole numbers are:

a = 1, b = 36

a = 2, b = 18

a = 3, b = 12

a = 4, b = 9

a = 6, b = 6

Therefore, there are 5 pairs of whole numbers with a geometric mean of 6.
