Camilla and Anne work as interior decorators in the city. Camilla can decorate a home in 5 days while Anne can
complete a home in 4 days. Working together, how long will it take them to decorate 2 homes?
Answer:
It will take them 4.44 days to decorate 2 homes.
Step-by-step explanation:
Given that:
Camilla can decorate a home in 5 days
Anne can complete a home in 4 days
Let,
x be the time taken by Camilla and Anne to decorate 1 home.
\(\frac{1}{Camilla's time}+\frac{1}{Anne's\ time} = \frac{1}{total\ time}\\\)
\(\frac{1}{5}+\frac{1}{4}=\frac{1}{x}\)
Taking LCM;
\(\frac{4+5}{20}=\frac{1}{x}\\\\\frac{9}{20}=\frac{1}{x}\\x=\frac{20}{9}\)
Time taken by Camilla and Anne to decorate 2 homes = \(\frac{20}{9}*2=\frac{40}{9}\)
Time taken to decorate Camilla and Anne 2 homes = 4.44 days
Hence,
It will take them 4.44 days to decorate 2 homes.

Hi student, let me help you out!
................................................................................................................
First, let's recall what \(\mathtt{a-(-b)}\) is equal to.
\(\mathtt{a-(-b)=a+b}\). Please remember that.
Now, let's use this little rule to simplify our expression, which is \(\mathtt{x-(-6x)}\).
We already know that \(\mathtt{x-(6x)=x+6x}\).
Now it's just a matter of combining like terms: \(\mathtt{x+6x=7x}\)
Thus, the expression \(\mathtt{x-(-6x)}\) equals \(\bigstar\underline{\boxed{\mathtt{7x}}}\).
Hope this helped you out, ask in comments if any queries arise.

The correct answers are:
- Question 8: All of these answers are correct.
- Question 9: 720.
- Question 10: Sample is used to estimate the population parameter.
- Question 11: Decreases.
- Question 12: 200 and 2.
- Question 13: Approximately normal for large sample sizes.
- Question 14: 0.9772.
Question 8: The point estimators are μ (population mean) and s (sample standard deviation). The symbol σ represents the population standard deviation, not a point estimator. Therefore, the correct answer is "All of these answers are correct."
Question 9: To determine the number of different samples of size 3 (without replacement) from a population of size 10, we use the combination formula. The formula for combinations is nCr, where n is the population size and r is the sample size. In this case, n = 10 and r = 3. Plugging these values into the formula, we get:
10C3 = 10! / (3!(10-3)!) = 10! / (3!7!) = (10 x 9 x 8) / (3 x 2 x 1) = 720
Therefore, the answer is 720.
Question 10: In point estimation, the sample is used to estimate the population parameter. So, the correct answer is "sample is used to estimate the population parameter."
Question 11: As the sample size increases, the variability among the sample means decreases. This is known as the Central Limit Theorem, which states that as the sample size increases, the distribution of sample means becomes more normal and less variable.
Question 12: The mean of the distribution of sample means is equal to the mean of the population, which is 200. The standard error of the distribution of sample means is equal to the standard deviation of the population divided by the square root of the sample size. So, the standard error is 18 / √81 = 2.
Question 13: For a population with an unknown distribution, the form of the sampling distribution of the sample mean is approximately normal for large sample sizes. This is known as the Central Limit Theorem, which states that regardless of the shape of the population distribution, the distribution of sample means tends to be approximately normal for large sample sizes.
Question 14: To find the probability that the mean from a sample of 49 observations will be larger than 82, we need to calculate the z-score and find the corresponding probability using the standard normal distribution table. The formula for the z-score is (sample mean - population mean) / (population standard deviation / √sample size).
The z-score is (82 - 80) / (7 / √49) = 2 / 1 = 2.
Looking up the z-score of 2 in the standard normal distribution table, we find that the corresponding probability is 0.9772. Therefore, the probability that the mean from the sample will be larger than 82 is 0.9772.
Overall, the correct answers are:
- Question 8: All of these answers are correct.
- Question 9: 720.
- Question 10: Sample is used to estimate the population parameter.
- Question 11: Decreases.
- Question 12: 200 and 2.
- Question 13: Approximately normal for large sample sizes.
- Question 14: 0.9772

Calculate the following by drawing the cash flow diagram for a facility with an initial investment cost of 10 million TL.
a) Net present value (NPV) for i=0.1
b) If the revenues obtained are invested in an investment instrument with an interest rate of 7.5%, at the end of the service life of the firm.
his earnings.
If the revenues obtained from the facility are invested in an investment instrument with an interest rate of 7.5% at the end of the service life, the total earnings will be 41.303 million TL.
To calculate the net present value (NPV) of the facility's cash flows, we need to discount each cash flow to its present value using a discount rate of 10% (i=0.1). The cash flow diagram for the facility is as follows:
Year 1: +3 million TL
Year 2: +3 million TL
Year 3: +3 million TL
Year 4: +3 million TL
Year 5: +4 million TL
Year 6: +4 million TL
Year 7: +4 million TL
Year 8: +4 million TL
Year 9: +4 million TL
Year 10: +4 million TL
To calculate the NPV, we need to discount each cash flow and sum them up. The formula for calculating the present value (PV) of a cash flow is:
PV = CF / (1 + r)^n
Where:
CF = Cash flow
r = Discount rate
n = Number of periods
Using the formula, we can calculate the present value of each cash flow:
Year 1: 3 million TL / (1 + 0.1)^1 = 2.727 million TL
Year 2: 3 million TL / (1 + 0.1)^2 = 2.479 million TL
Year 3: 3 million TL / (1 + 0.1)^3 = 2.254 million TL
Year 4: 3 million TL / (1 + 0.1)^4 = 2.058 million TL
Year 5: 4 million TL / (1 + 0.1)^5 = 2.859 million TL
Year 6: 4 million TL / (1 + 0.1)^6 = 2.599 million TL
Year 7: 4 million TL / (1 + 0.1)^7 = 2.363 million TL
Year 8: 4 million TL / (1 + 0.1)^8 = 2.147 million TL
Year 9: 4 million TL / (1 + 0.1)^9 = 1.951 million TL
Year 10: 4 million TL / (1 + 0.1)^10 = 1.772 million TL
Now, we sum up the present values of all cash flows:
NPV = -10 million TL + 2.727 million TL + 2.479 million TL + 2.254 million TL + 2.058 million TL + 2.859 million TL + 2.599 million TL + 2.363 million TL + 2.147 million TL + 1.951 million TL + 1.772 million TL
NPV = -10 million TL + 23.869 million TL
NPV = 13.869 million TL
Therefore, the net present value (NPV) for a discount rate of 10% (i=0.1) is 13.869 million TL.
b) If the revenues obtained from the facility are invested in an investment instrument with an interest rate of 7.5% at the end of the service life, we can calculate the future value of the cash flows. Since the cash flows occur at the end of each year, we can simply calculate the future value (FV) of each cash flow using the formula:
FV = CF * (1 + r)^n
Where:
CF = Cash flow
r = Interest rate
n = Number of periods
Calculating the future value of each cash flow and summing them up will give us the total earnings:
Year 1: 3 million TL * (
1 + 0.075)^9 = 5.163 million TL
Year 2: 3 million TL * (1 + 0.075)^8 = 4.783 million TL
Year 3: 3 million TL * (1 + 0.075)^7 = 4.428 million TL
Year 4: 3 million TL * (1 + 0.075)^6 = 4.097 million TL
Year 5: 4 million TL * (1 + 0.075)^5 = 4.636 million TL
Year 6: 4 million TL * (1 + 0.075)^4 = 4.271 million TL
Year 7: 4 million TL * (1 + 0.075)^3 = 3.934 million TL
Year 8: 4 million TL * (1 + 0.075)^2 = 3.626 million TL
Year 9: 4 million TL * (1 + 0.075)^1 = 3.345 million TL
Year 10: 4 million TL * (1 + 0.075)^0 = 4 million TL
Now, we sum up the future values of all cash flows:
Total earnings = 5.163 million TL + 4.783 million TL + 4.428 million TL + 4.097 million TL + 4.636 million TL + 4.271 million TL + 3.934 million TL + 3.626 million TL + 3.345 million TL + 4 million TL
Total earnings = 41.303 million TL
Therefore, if the revenues obtained from the facility are invested in an investment instrument with an interest rate of 7.5% at the end of the service life, the total earnings will be 41.303 million TL.

Re-write the quadratic function below in Standard Form
y= 4(x + 8)(x - 2)
Answer:
4x^2+24x-64
Step-by-step explanation:
First you multiply (x+8) by (x-2). You can use this using the FOIL method which stands for first, outer, inner, last. Through this method you would multiply x by x first and get x^2, then x by -2 and get -2x, then 8 by x and get 8x, and finally 8 by -2 and get -16. You then add this all together and get x^2-2x+8x-16 or x^2+6x-16.
Now all you have to do is multiply each term by 4 and get 4x^2+24x-64 using the distributive property.

A description of the distribution of the values of a random variable and their associated probabilities is called a probability distribution. The correct answer is a.
A probability distribution is a mathematical function that describes the possible values of a random variable and the likelihood of each value occurring. It provides a complete description of the probabilities of all possible outcomes of a random experiment or event.
Probability distributions can be classified into two types: discrete probability distributions and continuous probability distributions. Discrete probability distributions are used when the possible outcomes of a random variable are countable or finite, such as the number of heads in a coin toss.
Continuous probability distributions, on the other hand, are used when the possible outcomes of a random variable are infinite, such as the time it takes for a person to complete a task.
Probability distributions are used in various fields, such as statistics, finance, engineering, and science, to model and analyze random phenomena and make predictions about future events. They are an essential tool for understanding uncertainty and making informed decisions based on probabilistic outcomes.

A small pool for children has some water in it. Jabari uses a garden hose to add water to it.
The total amount of water in gallons, y, is a function of the time in minutes since Jabari turns
on the hose, a.
-)
The graph of the linear function passes through the points (2, 44) and (5, 80).
What is the equation of the function?
y= 12 + 20
How much water is in the pool when Jabari turns on the hose?
Answer:
20 gallons.
Step-by-step explanation:
The given points (2, 44) and (5, 80) represent two points on the linear function that relates the total amount of water in the pool to the time since Jabari turns on the hose. We can use these points to find the equation of the function in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.
To find the slope, we can use the formula:
m = (y2 - y1) / (x2 - x1)
Using the two given points, we get:
m = (80 - 44) / (5 - 2)
m = 12
To find the y-intercept, we can use the point-slope form of the equation and substitute one of the given points, say (2, 44), for x and y, and the slope we just found for m:
y - y1 = m(x - x1)
y - 44 = 12(x - 2)
y - 44 = 12x - 24
y = 12x + 20
So the equation of the function that relates the total amount of water in the pool to the time since Jabari turns on the hose is:
y = 12x + 20
When Jabari turns on the hose, the time since he turns on the hose is 0 minutes. Substituting a = 0 into the equation we just found, we get:
y = 12(0) + 20
y = 20
Therefore, when Jabari turns on the hose, there is already 20 gallons of water in the pool.

A sampling distribution, also known as a finite-sample distribution, in statistics is the probability distribution of a given random-sample-based statistic. The sampling distribution is the probability distribution of the values that the statistic takes on if an arbitrarily large number of samples, each involving multiple observations (data points), were used separately to compute one value of a statistic (such as, for example, the sample mean or sample variance) for each sample. Although only one sample is frequently observed, the theoretical sampling distribution can be determined.
Because they offer a significant simplification before drawing conclusions using statistics, sampling distributions are crucial in the field. They enable analytical decisions to be made based on the probability distribution of a statistic rather than the combined probability distribution of all the individual sample values
