Answer:

y = 17/4 - 3/4x

Step-by-step explanation:

\(3x + 4y = 17\)

Subtract 3x from both sides.

\(4y = 17 - 3x\)

Divide by 4 from both sides to isolate y.

\(y = \frac{17 - 3x}{4} \)

If American Airlines randomly selects a set of 40 flights on a given day and then randomly selects a group of passengers from each flight, the total number of passengers selected can vary depending on the specific number of passengers chosen from each flight.

To determine the total number of passengers selected, we need to know the number of passengers chosen from each flight. If we assume a constant number of passengers selected from each flight, we can multiply that number by the total number of flights (40) to calculate the total number of passengers.

For example, if American Airlines randomly selects 10 passengers from each of the 40 flights, the total number of passengers selected would be 10 * 40 = 400.

However, if the number of passengers selected varies across flights, then we would need specific information about the distribution of passenger numbers per flight or the probability distribution for selecting a particular number of passengers from each flight to calculate the total number of passengers accurately.

Therefore, the total number of passengers selected will depend on the specific number of passengers chosen from each flight, and without that information, we cannot determine the exact value.

The required rate of return for DAK Corporation is 12.34%.

What is the required rate?

The minimal profit (return) an investor will seek or expect in exchange for taking on the risk of investing in a stock or other type of security is known as the required rate of return (RRR). RRR can also be used to determine a project's potential profitability in relation to its funding costs.

Here, we have

Given Information

Beta =   1.25

The yield on 30-year T bonds (rf)=     5.65%

Return on S&P (rM) =    11%

Required Return for DAK = rf + Beta*(rM - rf)

= 5.65% + 1.25*(11% - 5.65%)

=  12.34%

Hence,  the required rate of return for DAK Corporation is 12.34%.

Step-by-step explanation:

40% is also .4, or you could do 40 divided by 100. Which will get you 0.4, 100 multiplied by .4 is 40, so if you multiply 20 by .4 you should get 40% of 20. (8)

Using the properties of parallelograms and the given information, we proved that BAEC is equal to FABC. We utilized angle-angle similarity and the proportional relationships of corresponding sides in similar triangles to establish the equality.

To prove that BAEC = FABC, we will use the properties of parallelograms and the given information.

Given:

ABCD is a parallelogram.

BE is parallel to CD.

BF is parallel to AD.

To prove:

BAEC = FABC

Proof:

Since ABCD is a parallelogram, we know that opposite sides are parallel and equal in length. Let's denote the length of AB as a, BC as b, AD as c, and CD as d.

Since BE is parallel to CD and AD is parallel to BF, we have angle ABE = angle CDF and angle ADB = angle BFD.

By alternate interior angles, angle CDF = angle FAB.

Now, we have two pairs of congruent angles: angle ABE = angle CDF and angle ADB = angle BFD.

Using angle-angle similarity, we can conclude that triangle ABE is similar to triangle CDF and triangle ADB is similar to triangle BFD.

As the corresponding sides of similar triangles are proportional, we have the following ratios:

AB/CD = AE/CF (from triangle ABE and triangle CDF similarity)

AD/BC = BD/CF (from triangle ADB and triangle BFD similarity)

Cross-multiplying the ratios, we get:

AB * CF = CD * AE (equation 1)

AD * CF = BC * BD (equation 2)

Adding equation 1 and equation 2, we have:

AB * CF + AD * CF = CD * AE + BC * BD

Factoring out CF, we get:

CF * (AB + AD) = CD * AE + BC * BD

Since AB + AD = CD (opposite sides of a parallelogram are equal), we have:

CF * CD = CD * AE + BC * BD

Simplifying, we get:

CF = AE + BC

Therefore, we have shown that BAEC = FABC.

The given statement "For a fixed confidence level, when the sample size decreases, the length of the confidence interval for a population mean decreases." is false because as the sample size decreases, the precision of the estimate decreases, resulting in a wider confidence interval for a population mean.

When the sample size decreases, the length of the confidence interval for a population mean tends to increase, not decrease.

The confidence interval is a range of values within which we can expect the population mean to fall with a certain level of confidence.

It is calculated based on the sample mean, sample standard deviation , and sample size. The formula for the confidence interval is:

Confidence interval = sample mean ± (critical value) × (standard deviation / √sample size)

The critical value is determined based on the desired confidence level. As the sample size decreases, the denominator (√sample size) becomes smaller.

Since it is in the denominator, a smaller value leads to a larger result, causing the confidence interval to widen.

Intuitively, this makes sense because with a smaller sample size, there is less information available to estimate the population mean accurately.

Therefore, the range of plausible values for the population mean becomes wider, resulting in a longer confidence interval.

In conclusion, as the sample size decreases, the length of the confidence interval for a population mean tends to increase, indicating greater uncertainty in the estimate.

Step-by-step explanation:

T = total savings

w = number of weeks

Paige:

T = 350 + 25w

Cindy:

T = 190 + 40w

In how many weeks will Cindy have more money in her savings than Paige

Equate the total savings of both of them

350 + 25w = 190 + 40w

Collect like terms

350 - 190 = 40w - 25w

160 = 15w

w = 160/15

w = 10.67

Approximately,

In 11 weeks, will Cindy have more money in her savings than Paige

Check:

Paige:

T = 350 + 25w

= 350 + 25(11)

= 350 + 275

= 625

Cindy:

T = 190 + 40w

= 190 + 40(11)

= 190 + 440

= 630

This question is about Probability, and the probability is the number of outcomes of the event we try to find the probability over the number of outcomes in the sample space, that is, the number of all the cases we need to analyze.

In this case, we have that the sample space is the total number of persons:

1. Women: 7

2. Men: 3

Then, the number of outcomes in the sample space is women + men = 7 + 3 = 10.

We can say the event is a woman in that sample space, we have 7 women.

Therefore, the event that a person is a woman is:

In summary, the probability to find a person that is a woman in an office is:

A result is called "statistically significant" when the p-value is less than the significant level, typically 0.05.

This means that there is less than a 5% chance that the results are due to chance alone, and suggests that there is a real effect present in the data.

The Null Hypothesis is the assumption that there is no significant difference between the measured phenomenon and a certain value or set of values. A statistically significant result means that the observed data are inconsistent with the assumption of no difference, or no effect.
