An employee at the metropolitan museum of art surveyed a random sample of 150 visitors to the museum. Of those visitors, 45 people bought food at the cafeteria. Based on those results, how many people out of 1750 visitors to the museum would be expected to buy food for the cafeteria? No links
Answers
We can expect that approximately 525 people out of 1750 visitors to the museum would buy food at the cafeteria.
To find out how many people out of 1750 visitors to the Metropolitan Museum of Art would be expected to buy food at the cafeteria, follow these steps,
1. Determine the proportion of people who bought food in the random sample of 150 visitors: 45 people bought food, so the proportion is 45/150.
2. Simplify the proportion: 45/150 = 0.3 or 30%.
3. Apply this proportion to the total number of 1750 visitors: 1750 * 0.3 = 525.
So, based on the survey results, we can expect that approximately 525 people out of 1750 visitors to the museum would buy food at the cafeteria.

a pet store has 115 fish and each tank can hold six fish how many tanks do you nedd
Answers
Answer:
20 tanks
Step-by-step explanation:
if each tank holds 6 fish and there are 115 fish, you need to divide the amount of fish total by amount that go in 1 tank:
115/6 = 19.1666666667
Now we round up bc we cant leave any fish out right?
So your answer is 20 tanks will be needed to hold 115 fish if it’s 6 fish per tank.
Check this by multiplying the tanks and fish in every tank:
20 x 6 = 120
Meaning that 115 fish go into 20 tanks, one of the tanks just having 1 fish :D
Answer: 20 is the correct option.
Step-by-step explanation:Given that a pet store has 115 fish that need to be placed into fish tanks and each tank hold 6 fish.
We are to find the number of tanks that the store need.
We will be using the UNITARY method to solve the given problem.
Number of tanks needed to store 6 fishes = 1.
So, number of tanks needed to store 1 fish will be \(\frac{1}{6}\)
Therefore, number of tanks needed to store 115 fishes is given by
\(\frac{1}{6}\) × 155 =\(\frac{115}{6}\)= 19 \(\frac{1}{6}\) = 19.16.
Since we cannot have 0.16 tank, so we need one tank more than 19 to store all fishes.
Thus, the store needs 20 tanks for 115 fishes.

Net Present Value
A project has estimated annual net cash flows of $15,000 for ten
years and is estimated to cost $47,500. Assume a minimum acceptable
rate of return of 20%. Use
Answers
The required rate of return (or minimum acceptable rate of return) is 20 percent. If the net cash flows are $15,000 per year for ten years, the total cash flow is $150,000. The project's cost is $47,500. We can now apply the net present value formula to determine whether or not the project is feasible.
Net Present Value (NPV) = Cash flow / (1 + r)^n - Cost Where, r is the discount rate, n is the number of years, and Cost is the initial outlay.
Net Present Value = 150000 / (1 + 0.20)^10 - 47500
Net Present Value = $67,482.22
Since the NPV is positive, the project is feasible. When calculating net present value, it's important to remember that a positive NPV implies that the project is expected to generate a return that exceeds the cost of capital, whereas a negative NPV indicates that the project is expected to generate a return that is less than the cost of capital, and as a result, it should be avoided.

If done correctly, this will provide a great solution that will never fail you.
According to the given data:All of the probability will add upto 1.
this give us the equation:
P(1)+0.17 + 0.18 + 0.09 + 0.15 + 0.1 = 1
P(1) + 0.69 = 1
P(1) = 1 - 0.69
P(1) = 0.31
We now need to find the probability of 1 or 3
P(1 or 3) = P(1) + P(3)
= 0.31 + 0.18
= 0.49
We now use the predicting outcomes formula.
expected = P(1 or 3) x no. of times.

the total number of times the dice will land on 1 or on 3 = 98.

The cash flow identity is a useful tool for understanding the financial health of a company.
How to explain the cash flowCash flow from assets = Net income + Depreciation - Increase in net working capital - Capital expenditures
Net income = Sales revenue - Cost of goods sold - Selling, general, and administrative expenses - Depreciation
Using the data from the financial statements, we can calculate the cash flow from assets as follows:
Cash flow from assets = $238,900 + $46,200 - $1,900 - $120,000 = $102,100
Cash flow to creditors = $17,800 - $4,900 = $12,900
Cash flow to owners = $0 + $82,200 = $82,200
Cash flow from assets = Cash flow to creditors + Cash flow to owners
$102,100 = $12,900 + $82,200

what is the purpose of a variable? a. to assign values b. to perform calculations c. to hold a value d. to hold a constant value
Answers
The purpose of a variable is to hold and represent a value Option C.
The purpose of a variable in programming or mathematics is to hold and represent a value that can be assigned, changed, and used in various operations or calculations. Variables are fundamental components of programming languages and mathematical equations, enabling flexibility and dynamic behavior in computational tasks.
Option (c) "to hold a value" is the most accurate answer, as variables are used to store data or information in memory locations. This value can be of different types, such as integers, floating-point numbers, characters, or even more complex data structures like arrays or objects.
Variables allow programmers to work with and manipulate data efficiently. By assigning values to variables, we can reference and modify them throughout the program, making it easier to manage and organize information.
Variables also play a crucial role in performing calculations, as mentioned in option (b). We can use variables in mathematical expressions and algorithms to perform arithmetic operations, comparisons, and other computations. By storing values in variables, we can reuse them in multiple calculations and update them as needed.
While option (a) "to assign values" is a specific use case of variables, it is not the sole purpose. Variables not only store values but also facilitate data manipulation, control flow, and the implementation of algorithms and logic.
Option (d) "to hold a constant value" is incorrect because variables, by definition, can hold varying values. Constants, on the other hand, are fixed values that do not change during the execution of a program. Option C is correct.

b. Vorhuis c. Gouse
d. Lolka and Voera
Answers
The mathematicians credited with developing the mathematical models that predict population growth in each of two competing species are Rosenzweig and MacArthur(OPTION A).
These two scientists developed a theory known as the "competitive exclusion principle," which states that two species competing for the same resources cannot coexist indefinitely. Instead, one species will eventually outcompete and displace the other species.
Rosenzweig and MacArthur's model is based on the Lotka-Volterra equations, which are a set of differential equations that describe the dynamics of predator-prey relationships. They extended this model to include two competing species and developed the concept of the "ecological niche" – the specific set of environmental conditions under which a species can survive and reproduce.
Their model predicts that the two species will reach a stable equilibrium, where their populations remain relatively constant over time. However, the exact outcome of the competition depends on several factors, including the initial population sizes of the two species, the relative strengths of their ecological niches, and the availability of resources.
Overall, Rosenzweig and MacArthur's mathematical model has been influential in the field of ecology, providing a framework for understanding how competing species interact and how ecosystems evolve over time.

What is meant by probability?A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.
A) The likelihood that both adults believe that most famous people make good role models would be = (199/800) × (198/799) = 39402/639200 = 0.062
B) We're looking for the likelihood that neither adult believes that most famous people make good role models.
Today that 199 people out of 800 believe that most famous people make decent role models.
The percentage of people who disagree that most celebrities make for good role models = 800 - 199 = 601
The probability that neither adult thinks most celebrities exists good role models. would be = (601/800) × (600/799)= 180300/319600 = 0.564
C) We're looking for the likelihood that at least one of the two adults believes that most celebrities make for positive role models.
Now that we know that neither of them believes that the majority of famous people are good role models, we can simply deduct that probability from 1.
The likelihood that at least one of the two adults believes most famous people make good role models = 1 - 0.564 = 0.436

Answers
According to the suggested guidelines for using Cohen's d, a Cohen's d of .6 would represent a medium effect.
Cohen's d is a standardized measure of effect size that quantifies the difference between two groups or conditions in terms of the standard deviation. It is calculated by dividing the difference between the means of the two groups by the pooled standard deviation.
In general, the interpretation of Cohen's d is as follows:
A Cohen's d of around .2 is considered a small effect size.
A Cohen's d of around .5 is considered a medium effect size.
A Cohen's d of around .8 or higher is considered a large effect size.
Therefore, with a Cohen's d of .6, it falls within the range of a medium effect size. This indicates that there is a moderate difference between the means of the two groups, suggesting a meaningful effect in the context of the study or analysis.
It is important to note that the interpretation of effect size can vary depending on the field of study and the specific context in which it is applied.

True
False
Answers
The statement 'When you try to find the most appropriate input probability distribution in a simulation model, you first have to choose the most appropriate family, and then you have to select the most appropriate member of that family' is generally true because in simulation modeling, input probability distributions are used to represent uncertain or random factors in the system being modeled.
These distributions are often classified into different families, such as normal, exponential, uniform, and so on, based on their properties and mathematical characteristics.
When selecting an appropriate distribution for a simulation model, it is important to first identify the family of distributions that best represents the underlying random process being modeled.
For example, if the data is symmetric and bell-shaped, then the normal distribution might be a suitable family to consider. However, if the data is non-negative and skewed, then the exponential or gamma distribution might be more appropriate.
Once the appropriate family of distributions is selected, the next step is to identify the most appropriate member or parameter values of that family that best fit the data being modeled.
This often involves using statistical methods to estimate the parameters of the distribution based on historical data or expert knowledge.

There are
seats in row 18.
Answers
To figure out how many seats are increasing every row, we can use this equation:
48 - 44 = 4Now that we know that every row the seats increase by 4, we can multiply 4 by the number of rows, then add it back to the number of seats in the first row.
(17 × 4) + 44 = 112(We use 17 because we already have the number of seats for the first row, which is 44. If there are 18 rows, we simply don't count the first one.)
To check our work, we can add instead of multiply.
The first row has 44 seats.44 + 4 = 4848 + 4 = 5252 + 4 = 5656 + 4 = 6060 + 4 = 6464 + 4 = 6868 + 4 = 7272 + 4 = 7676 + 4 = 8080 + 4 = 8484 + 4 = 8888 + 4 = 9292 + 4 = 9696 + 4 = 100100 + 4 = 104104 + 4 = 108108 + 4 = 112There are 112 seats in row 18.
