Answer:

C pi/9

Explanation:

"We need to find the number that is not between 1 and 6.28.

A pi = 3.14; 3.14 is between 1 and 6.28, so this is not the answer.

B sqrt(9) = 3; 3 is between 1 and 6.28, so this is not the answer.

C pi/9 = 3.14/9 = 0.349; 0.349 is not between 1 and 6.28, so this is the answer.

D pi^2/9 = (3.14 * 3.14)/9 = 9.86/9 = 1.095; 1.095 is between 1 and 6.28, so this is not the answer." (mathstudent55) thank you to mathstudent55 for the answer.

Answer:

$9.00

Step-by-step explanation:

Let s = the cost for a sandwich.  

Let d = the cost of a drink

3s + 2d = 19                                                                                      3s + 2d = 19

2s + 1d = 12   → multiply this by -2 and add to the first equation  -4s -2d = -24

                                                                                                          -s          = -5

-s = -5  Divide both sides by -4

s = 5

A sandwich costs $5.00.

Substitute 5 for s

2s + 1d = 12

2(5) + 1d = 12

10 + 1d = 12  Subtract 10 from both sides

1d = 2

A drink costs $2.00

The cost of 1 sandwich and 2 drinks would be

5 + 2(2)

5 + 4 = 9

It will cost $9.00 for 1 sandwich and 2 drinks.

Step-by-step explanation:

The two most generic and widely used valuation multiples in finance and investment analysis are the price-to-earnings (P/E) ratio and the enterprise value-to-earnings before interest, taxes, depreciation, and amortization (EV/EBITDA) multiple.

1. Price-to-Earnings (P/E) Ratio: The P/E ratio is calculated by dividing the market price per share of a company's stock by its earnings per share (EPS). It provides a measure of how much investors are willing to pay for each dollar of earnings generated by the company.

A high P/E ratio suggests that investors have high expectations for future growth and are willing to pay a premium for the stock. On the other hand, a low P/E ratio may indicate that the stock is undervalued or that investors have low expectations for future growth.

2. Enterprise Value-to-EBITDA (EV/EBITDA) Multiple: The EV/EBITDA multiple is calculated by dividing the enterprise value (EV) of a company by its earnings before interest, taxes, depreciation, and amortization (EBITDA).

The EV is the total market value of a company's equity and debt, minus its cash and cash equivalents. EBITDA represents the company's operating earnings before accounting for interest, taxes, depreciation, and amortization.

The EV/EBITDA multiple is commonly used in evaluating the valuation of companies, especially in the context of mergers and acquisitions. It provides a measure of a company's overall value relative to its earnings, without being affected by capital structure or tax considerations.

Both the P/E ratio and EV/EBITDA multiple are widely used because they are relatively easy to calculate and understand. However, it's important to note that these multiples have limitations and should be used in conjunction with other valuation methods and qualitative analysis to make informed investment decisions.

To calculate the future value (FV) of $200 under different compounding periods, we can use the formula for compound interest:

FV = P(1 + r/n)^(nt)

where:

FV = Future Value

P = Principal amount (initial investment)

r = Annual interest rate (as a decimal)

n = Number of compounding periods per year

t = Number of years

Given:

P = $200

r = 4% = 0.04

t = 6 years

a. Compounded annually:

n = 1

FV = 200(1 + 0.04/1)^(1*6) = $200(1.04)^6 ≈ $251.63

b. Compounded semiannually:

n = 2

FV = 200(1 + 0.04/2)^(2*6) = $200(1.02)^12 ≈ $253.72

c. Compounded quarterly:

n = 4

FV = 200(1 + 0.04/4)^(4*6) = $200(1.01)^24 ≈ $254.92

d. Compounded monthly:

n = 12

FV = 200(1 + 0.04/12)^(12*6) = $200(1.0033)^72 ≈ $255.23

e. Compounded daily:

n = 365

FV = 200(1 + 0.04/365)^(365*6) = $200(1.0001096)^2190 ≈ $255.26

f. The observed pattern of future values (FVs) increasing with more frequent compounding is due to the effect of compounding interest more frequently. As the compounding periods increase (annually, semiannually, quarterly, monthly, daily), the interest is added to the principal more often, allowing for more significant growth over time. This compounding effect leads to slightly higher FVs as the compounding periods become more frequent.

The coordinates of the point closest to the origin are x = -1, y = 0, and z = 1.

To find the coordinates of the point (x, y, z) on the plane z = 1x + 1y + 2 that is closest to the origin, we can minimize the square of the distance from the origin to the point (x, y, z). The square of the distance, D², can be expressed as:

D² = x² + y² + (1x + 1y + 2 - 0)²

Taking partial derivatives with respect to x, y, and z and setting them to zero, we can find the critical points:

∂(D²)/∂x = 2x + 2(1x + 1y + 2)(1) = 0
∂(D²)/∂y = 2y + 2(1x + 1y + 2)(1) = 0

Solving these equations simultaneously:

x + y + 1 = 0
x = -y - 1

Substituting x into the equation for z:

z = 1(-y - 1) + 1y + 2
z = -y - 1 + y + 2
z = 1

So, the coordinates of the point closest to the origin are:
x = -1
y = 0
z = 1

1. The average time it takes a customer from when they arrive at the truck until they receive their taco is 141.67 seconds.

2. The average utilization of the truck 141.67 seconds.

3. On average, there is 1 person waiting in line.

4. In order to achieve a delay probability of under 10%, a minimum of 1 server is required.

1 The arrival rate is 1 customer every 2 minutes, which is equivalent to 0.5 customers per minute. The service rate is 1 customer per 50 seconds, which is equivalent to 1.2 customers per minute (since there are 60 seconds in a minute).

2 Average Number of Customers = (0.5 / 1.2) + 1 = 1.4167.

Average Waiting Time = 1.4167 * (50 + 50)

= 141.67 seconds.

3 The average utilization of the truck is given by the formula: Utilization = Arrival Rate / Service Rate.

Utilization = 0.5 / 1.2

= 0.4167 (or 41.67%).

The average number of people waiting in line can be calculated using the formula: Average Number of Customers - Average Utilization.

Average Number of Customers - Average Utilization = 1.4167 - 0.4167

= 1.

4 Given that the desired delay probability is 10% (or 0.1), we can rearrange the formula to solve for the utilization:

Utilization = Delay Probability / (1 + Delay Probability).

=

Utilization = 0.1 / (1 + 0.1) = 0.0909 (or 9.09%).

The utilization we calculated represents the maximum utilization to achieve a delay probability of 10%. In conclusion, to achieve a delay probability of under 10%, a minimum of 1 server is required.

According to the information, we can infer that the number of ounces of water, x, that Will could have put in each cup is 8 ounces.

Will initially had a cooler filled with 144 ounces of water. After using 16 ounces to fill his water bottle, there were 144 - 16 = 128 ounces of water remaining in the cooler.

Will then took out 16 plastic cups for his teammates. Since the same amount of water was put in each cup, the remaining amount of water, 128 ounces, needs to be divided equally among the cups.

Dividing 128 ounces by 16 cups gives us 8 ounces of water for each cup.

So, Will could have put 8 ounces of water in each cup.

Answer:

2 bus

Step-by-step explanation:

The expected value of y is larger than the expected value of x. This is because y takes into account the number of students on all 4 buses, while x only takes into account the students on the bus with the randomly selected student.

The expected value of a random variable represents the average value of that variable over multiple trials. In this case, x is a random variable representing the number of students on the bus carrying the randomly selected student, and y is a random variable representing the number of students on the randomly selected bus.

The expected value of x can be calculated as follows:

E[x] = (10/100)×10 + (20/100)×20 + (30/100)×30 + (40/100)×40

= 16 + 12 + 9 + 16

= 53/4

= 13.25

This means that, on average, the bus carrying the randomly selected student would have 13.25 students.

The expected value of y can be calculated as follows:

E[y] = (1/4)×10 + (1/4)×20 + (1/4)×30 + (1/4)×40

= 25

This means that, on average, the randomly selected bus would have 25 students.

As expected, the expected value of y is larger than the expected value of x. This is because y takes into account the number of students on all 4 buses, while x only takes into account the students on the bus with the randomly selected student. Since the number of students on the other 3 buses can vary widely, y has a higher expected value than x.

Answer: which one

Step-by-step explanation:

Yes, the forester was justified in using a Normal model to analyze the woods, because the histogram is unimodal and symmetric. So option A is correct.

A histogram is a type of graph that uses vertical bars to show the distribution of a set of data. This particular histogram is unimodal, meaning that it has one peak which is an indication that the data is distributed normally. Additionally, the histogram is symmetric, which is another indication that the data is normally distributed.
Using a Normal model to analyze the woods is a valid approach because it allows the forester to identify the average diameter of the trees, as well as the spread of the data. It also allows him to check for any outliers, or points that fall outside the normal range. With this information, the forester can determine if the woods is suitable for sale, or if the buyer should be aware of any unexpected features.
Overall, the histogram is an effective way for the forester to analyze the data and determine if a Normal model is appropriate. By noting the unimodal and symmetric nature of the histogram, the forester can be sure that a Normal model will accurately represent the data, allowing him to make an informed decision about the woods.

Answer: -178.1

Step-by-step explanation:

-71.24 ÷ 0.4

You have to use the rules for division, meaning that when you are DIVIDING a negative and a positive, it stays a negative. (-) ÷ (+) = (-)

-(71.24 ÷ 0.4)

Then just divide the numbers

Which gives you your answer: -178.1

Answer:

  (a)  -178.1

Step-by-step explanation:

You want the quotient of -71.24 and 0.4.

There is one minus sign (an odd number) in this quotient, so the result will be negative.

Dividing by 0.4 = 2/5 is the same as multiplying by the reciprocal of that: 5/2. That is, the result will be somewhat more than double the value -70. It will not be 17 or 1700. The correct choice of magnitude is 178.1.

When the sign is added to the magnitude, the result is -178.1.
