If 148/4 is 37, he will drive 37 miles in 1 hour.

The probability of randomly selected patient selected for coronary, oncology or both is equal to P( H∪C ) = 0.24.

Let patient admitted with heart disease represented by P(H)

P(H) = 12%

       = 0.12

And patient admitted for cancer disease represented by P(C)

P(H) = 16%

       = 0.16

Percent of patient received both coronary and oncology = 4%

P( H∩C ) = 0.04

Probability of randomly selected patient admitted for coronary, oncology or both is :

P( H∪C ) = P(H) + P(C) - P(H∩C )

⇒P( H∪C ) = 0.12 + 0.16 - 0.04

⇒ P( H∪C ) = 0.24

Therefore, the probability of randomly selected patient getting treatment for coronary, oncology or both is given by  P( H∪C ) = 0.24.

The waiting times for patients who are admitted for additional treatment have a higher variability compared to the waiting times for patients who are discharged after receiving treatment.

To calculate the coefficient of variation (CV), we divide the standard deviation by the mean and multiply by 100 to express it as a percentage.

For patients admitted for additional treatment:

CV = (12.7 / 121) * 100 ≈ 10.5%

For patients discharged after receiving treatment:

CV = (10.5 / 118) * 100 ≈ 8.9%

Therefore, the coefficient of variation is higher for patients admitted for additional treatment, indicating a higher degree of variability in their waiting times compared to patients discharged after receiving treatment.

The earnings per share can be calculated as $0.066 per share (rounded to the nearest cent).

a. The earnings per share for Company XYZ can be calculated by dividing the closing price by the P/E ratio. In this case, the closing price is $100.76 and the P/E ratio is 1525. Therefore, the earnings per share can be calculated as $0.066 per share (rounded to the nearest cent).

b. Based on the historical P/E ratio range of 12-14, the stock price of Company XYZ seems overpriced. The P/E ratio indicates the price investors are willing to pay for each dollar of earnings generated by the company. A higher P/E ratio suggests that investors have higher expectations for future earnings growth. In this case, the P/E ratio of 1525 is significantly higher than the historical range of 12-14, indicating that the stock is being valued at a much higher premium relative to its earnings. This suggests that the stock price may be inflated and not in line with the company's historical valuation metrics, indicating an overpriced condition.

Answer:

-x

Step-by-step explanation:

Simplifying

5x + 2 = 3x

Reorder the terms:

2 + 5x = 3x

Solving

2 + 5x = 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

2 + 5x + -3x = 3x + -3x

Combine like terms: 5x + -3x = 2x

2 + 2x = 3x + -3x

Combine like terms: 3x + -3x = 0

2 + 2x = 0

Add '-2' to each side of the equation.

2 + -2 + 2x = 0 + -2

Combine like terms: 2 + -2 = 0

0 + 2x = 0 + -2

2x = 0 + -2

Combine like terms: 0 + -2 = -2

2x = -2

Divide each side by '2'.

x = -1

Simplifying

x = -1

= -x

Answer/Step-by-step explanation:

a. Using a point on the graph, (6, 12), and the slope of the line, we can first generate an equation in the point-slope form, given as \( y - b = m(x - a) \), where,

m = slope, and (a, b) is a point on the line.

Using two points, (6, 12) and (3, 21), let's find slope, m.

\( slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{21 - 12}{3 - 6} = \frac{9}{-3} = -3 \)

Using a point (6, 12) and slope, m = -3, generate an equation in the point-slope form by substituting a = 6, b = 12, and m = -3 in \( y - b = m(x - a) \).

✅Equation in point-slope form would be:

\( y - 12 = -3(x - 6) \)

Rewrite this to make it be in the slope-intercept form, \( y = mx + b \).

\( y - 12 = -3(x - 6) \)

\( y - 12 = -3x + 18 \)

Add 12 to both sides

\( y = -3x + 18 + 12 \)

\( y = -3x + 30 \)

✅The equation in slope-intercept form is \( y = -3x + 30 \)

b. ✍️Based on the linear model, \( y = -3x + 30 \), the 30 represents b = y-intercept.

✅Therefore, it took Peter 30 mins long initially to deliver his package.

✍️Based on the linear model, \( y = -3x + 30 \), "-3" represents the slope.

✅Therefore,  Peter's delivery time decreased 3 mins per day.

False. According to Deming, most processes are not naturally in control and often require statistical control. Deming emphasized the importance of understanding and managing variation in processes to achieve better quality and efficiency.

    Contrary to the statement, Deming believed that most processes are not naturally in control. He emphasized the need for statistical control methods to manage processes effectively. Deming's approach was rooted in the understanding of variation and its impact on quality and productivity.

Deming advocated for the use of control charts to monitor processes and identify when they are out of control. Control charts provide a visual representation of process variation and help distinguish between common cause and special cause variation. Common cause variation is inherent in the process and can be reduced through process improvement efforts. Special cause variation, on the other hand, indicates that the process is influenced by external factors or unusual circumstances and requires immediate attention.

By using statistical control methods, organizations can proactively identify and address variations in their processes, leading to improved quality and increased efficiency. Deming's philosophy emphasizes the importance of managing variation to achieve stable and predictable processes, ultimately driving continuous improvement.

Slope is  $0.15 of the equation of cost  C=$0.15t+$35.00.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Given that A cell phone company uses the equation C=$0.15t+$35.00

C is the total cost for a month of service.

t is the number of text messages.

We have to find the slope of the equation.

slope is 0.15 and 35.00 is the y intercept of the equation given.

Hence, slope is  $0.15 of the equation of cost  C=$0.15t+$35.00.

The domain of f(g(x)) = (-infinity, -4) U [-4, 4) U (4, infinity).

To find the domain of f(g(x)), we first need to find the domain of g(x) and then the domain of f(x).

The domain of g(x) is the set of all real numbers x such that x + 4 >= 0. So, g(x) is defined for all x >= -4.

To find the domain of f(x), we need to exclude the values of x for which f(x) is not defined. In this case, f(x) is not defined for x = 4. Hence, the domain of f(x) is all real numbers except 4, i.e., (-infinity, 4) U (4, infinity).

Therefore, the domain of f(g(x)) is the set of all real numbers x such that g(x) is defined and g(x) belongs to the domain of f(x). This means that f(g(x)) is defined for all x >= -4, except x = 4.

So, the domain of f(g(x)) = (-infinity, -4) U [-4, 4) U (4, infinity).

The result implies that Jane should not play the game since her certainty equivalent is lower than the value of the sure thing, $45.

The question is asking for Jane's certainty equivalent given the option to either take $45 or to take the chance of winning $100 if the next coin flip comes up heads. This calculation requires selecting between two utility functions. These two utility functions are as follows:

Function A: u=4∗ 111x (4 times 1.1 root of x )

Function B: u= x1 (1 divided by x )

Explanation of selecting the correct utility function from Functions A and B:

The two functions given are:

Function A: u=4∗ 111x (4 times 1.1 root of x )

Function B: u= x1 (1 divided by x )

To solve the problem, the correct utility function must be chosen from these two utility functions. To choose between these two utility functions, the concept of risk aversion must be taken into account. In economics, risk aversion is a preference for a sure thing over a gamble with equal expected value.

In simple terms, this means that individuals are more willing to take the certainty of a known payout rather than the risk of not getting a payout at all. This concept can be used to select the correct utility function. Utility function A can be used to calculate the certainty equivalent for Jane as it exhibits risk aversion.

Therefore, Jane would prefer a certain payout of $x rather than taking a chance with an uncertain payout of $100 with probability 1/2.

Calculation of certainty equivalent for Jane:

Function A: u=4∗ 111x (4 times 1.1 root of x )

The formula for the certainty equivalent (CE) is as follows: 100 (1/2) = CE (1) + 45 (1/2)

The formula is derived from the fact that the expected value of playing the game is equal to the expected value of taking the sure thing.

Therefore, the probability of winning multiplied by the payout of winning is equal to the probability of taking the sure thing multiplied by the payout of the sure thing. The CE is $40.05.

The result implies that Jane should not play the game since her certainty equivalent is lower than the value of the sure thing, $45.

Answer:

(2,-5)

Step-by-step explanation:

See attachment

One can also solve this by calculation:

y=2x-9

y=-2x-1

-

Rearrange either equation to find x.  I'll use the first:

y=2x-9

2x = y+9

x = (y+9)/2

Now use this value of x in the second equation:

y =  -2x-1

y =-2((y+9)/2)-1

y = (-2y-18)/2)-1

y = -y -9 - 1

2y = -10

y = -5

Now use -5 for y in the rearranged equation:

y =  -2x-1

-5 =  -2x-1

-2x = -4

x = 2

Solution is (2,-5)

Rounded to the hundredth place, this gives us answer choice (D), which is the correct answer. So we can say with 90% confidence that the average number of hours of sleep for working college students is between 6.46 and 6.54 hours.

To calculate the confidence interval using the t-distribution, we use the formula:

Confidence interval = sample mean ± (t-score)*(standard error)

where the standard error is calculated as the standard deviation divided by the square root of the sample size, i.e.,

standard error = standard deviation / sqrt(sample size)

In this case, Morgan sampled 101 students and found an average of 6.5 hours of sleep with a standard deviation of 2.14. So the standard error is:

standard error = 2.14 / sqrt(101) = 0.213

The t-score for a 90% confidence level with 100 degrees of freedom (n-1) is 1.660, as given in the problem.

Therefore, the confidence interval is:

Confidence interval = 6.5 ± (1.660)*(0.213) = (6.46, 6.54).

Step-by-step explanation:

Here, we want to find the value of x

We use the principle of similar triangles here

We have these as;

(x + 2)/6 = x/4

4(x + 2) = 6x

4x + 8 = 6x

6x - 4x = 8

2x = 8

x = 8/2

x = 4

We proceed to get w;

The slope of a logarithmic graph depends on the type of logarithm used.

For a logarithmic function in the form y = log(b,x) where b is the base of the logarithm, the slope of the graph is undefined for x=0 and for x<0 because logarithmic functions are not defined in those cases.

For a natural logarithm, the slope is negative infinity at x=0 and positive for x > 0. As x increases, the slope becomes closer to zero.

For a common logarithm, the slope is negative infinity at x=0 and positive for x > 0. As x increases, the slope becomes closer to zero.

It's important to note that logarithmic functions are not linear functions, and therefore they do not have a constant slope, the slope of a logarithmic graph will change throughout the graph.
