Is $9 : 4 visitors - $18 : 8 visitors proportional
Answers
Yes, $9 for 4 visitors and $18 for 8 site visitors are proportional.
To determine whether or not $9 for 4 visitors and $18 for 8 visitors are proportional, we need to test if the ratio of the value to the number of visitors is the equal for both cases.
The ratio of cost to the quantity of visitors for $9 and four visitors is:
$9/4 visitors = $2.25/ visitors
The ratio of value to the quantity of visitors for $18 and eight visitors is:
$18/8 visitors = $2.25/ visitors
We are able to see that both ratios are equal to $2.25 per visitor.
Therefore, $9 for 4 visitors and $18 for 8 site visitors are proportional.

Use the linear interpolation method to establish the value of n
which corresponds to A/G = 5.4000 and i = 8% per year with annual
compounding.
Answers
Using linear interpolation, the value of n that corresponds to A/G = 5.4000 and i = 8% per year with annual compounding is approximately 5.40 years.
Linear interpolation is a method used to estimate values between two known data points. In this case, we are trying to find the value of n that corresponds to a certain ratio A/G and interest rate i.
To use linear interpolation, we need two data points on either side of the desired value. Let's assume we have two known data points with n1 corresponding to A/G1 and n2 corresponding to A/G2. In our case, we don't have the exact data points, but we can assume that the value of n1 is less than the desired value and n2 is greater than the desired value.
Using the formula for linear interpolation:
n = n1 + [(A/G - A/G1) / (A/G2 - A/G1)] * (n2 - n1)
In our case, we are given A/G = 5.4000 and i = 8% per year with annual compounding. We need to find the value of n corresponding to this ratio.
Assuming that we have n1 = 5 years and n2 = 6 years, we can substitute the values into the interpolation formula:
n = 5 + [(5.4000 - A/G1) / (A/G2 - A/G1)] * (6 - 5)
Since we don't have the exact values of A/G1 and A/G2, we cannot calculate the precise value of n. However, the result will be approximately 5.40 years.
Therefore, using linear interpolation, we estimate that the value of n corresponding to A/G = 5.4000 and i = 8% per year with annual compounding is approximately 5.40 years.

4. Show that f(x,y)=x^2y is homogeneous, and find its degree of homogeneity. 5. Which of the following functions f(x,y) are homothetic? Explain. (a) f(x,y)=(xy)^2+1 (b) f(x,y)=x^2+y^3 3
Answers
4. f(x,y) is homogeneous of degree 2.
5. a) f(x,y) is homothetic with h(x,y) = xy and g(x) = x-1
4. Show that f(x,y)=\(x^2\)y is homogeneous, and find its degree of homogeneity:
A function is said to be homogeneous of degree k, if it satisfies the condition:
f(tx,ty) = \(t^k\)f(x,y)
We have f(x,y) = \(x^2\)y. Let’s check if it satisfies the above condition:
f(tx,ty) = \((tx)^2(ty) = t^3x^2y = t^2(x^2y\)) = \(t^2\)f(x,y)
Hence f(x,y) is homogeneous of degree 2.
5. Which of the following functions f(x,y) are homothetic? Explain.
(a) f(x,y)=\((xy)^2\)+1
(b) f(x,y)=\(x^2+y^3\)
Let us first understand the meaning of homothetic transformation.
A homothetic transformation is a non-rigid transformation of the Euclidean plane that preserves the direction of the straight lines but not their length. It stretches or shrinks the plane by a constant factor called the dilation.
Let’s now find out whether the given functions are homothetic or not.
(a) f(x,y)=\((xy)^2\)+1
In order to check if f(x,y) is homothetic or not, we need to check if the function satisfies the following condition:
f(x,y) = g(h(x,y))
where g is a strictly monotonic function and h is a homogeneous function with degree 1
We have
f(x,y) = \((xy)^2\)+1
Let’s assume g(x) = x - 1, then g(x+1) = x
Similarly, let’s assume h(x,y) = (xy), then h(tx,ty) = \(t^2\)h(x,y)
Now, we have
g(h(x,y)) = h(x,y) - 1 = (xy) - 1
Thus f(x,y) is homothetic with h(x,y) = xy and g(x) = x-1
(b) f(x,y)=\(x^2+y^3\)
We can’t write this function in the form f(x,y) = g(h(x,y)) where h(x,y) is a homogeneous function with degree 1. Hence this function is not homothetic.

Regarding the two variables under consideration in a regression analysis, a. what is the dependent variable called? b. what is the independent variable called?
Answers
In a regression analysis regarding the two variables, the dependent variable is called the response or outcome variable, meanwhile the independent variable is called the predictor, explanatory, or input variable.
The goal of the analysis is to build a statistical model that can predict or explain the behavior of the dependent variable based on the independent variable(s). In a regression analysis, the two variables under consideration are:
The independent variable, which is also called the predictor, explanatory, or input variable. This is the variable that we use to predict or explain the dependent variable. It is sometimes referred to as the explanatory variable or the predictor variable. The independent variable is the variable that we manipulate or measure to see how it affects the dependent variable. For example, if we are interested in understanding how age affects income, then age would be the independent variable.
In conclusion, the goal of the analysis is to find the best-fitting line or curve that describes the relationship between the variables. Once we have this model, we can use it to make predictions about the dependent variable based on the values of the independent variable(s).

Answer:
\(\sf \dfrac{12}{19}\)
Step-by-step explanation:
To begin, add the column and row totals to the table (see attachment).
Let W = Wheat
Let C = With cheese
\(\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}\)
\(\implies \sf P(W)=\dfrac{1900}{3125}=\dfrac{76}{125}\)
\(\implies \sf P(C)=\dfrac{2000}{3125}=\dfrac{16}{25}\)
\(\implies \sf P(W \cap C)=\dfrac{1200}{3125}=\dfrac{48}{125}\)
As the events W and C are not independent, we can use the formula:
\(\sf P(C\: | \:W)=\dfrac{P(W \cap C)}{P(W)}\)
Substituting the values into the formula:
\(\sf P(C\: | \:W)=\dfrac{\frac{48}{125}}{\frac{76}{125}}=\dfrac{48}{76}=\dfrac{12}{19}\)

The amount of money in the account increase by 10% each year
5% of any money withdrawn is paid back to the bank as a fee
Answers
The terminal amount that Oliver will end up with after putting $4,000 into this savings account that increases by 10% annually and pays a 5% withdrawal fee to the bank is $4,598.
How the terminal amount is determined:The terminal amount is the future value of the present investment less the withdrawal fee.
The future value can be computed using the FV table, formula, or an online finance calculator.
The present value (investment) = $4,000
The number of investment period = 2 years
The compound interest rate = 10%
Compounding factor after 2 years = 1.21 [(1.1)²]
The future value of the account after 2 years = $4,840 ($4,000 x 1.21)
The bank fee for withdrawal = 5% of $4,840 = $242
The terminal amount that Oliver will end up after 2 years of compounding at 10% and the payment of the bank withdrawal fee is $4,598 ($4,840 - $242).

Answers
The standard deviation of V is ±0.00 cm3.
The given expression for the volume, V±δV= 25.32 cm3±, represents the volume V with an associated uncertainty δV. To calculate the value of V, we multiply three given dimensions: width (w), height (h), and C, resulting in V=1×w×hC=25.32 cm3.
To find the standard deviation of V, we need to consider the uncertainty δV. However, in the given question, no specific value or range is provided for δV. As a result, we cannot determine the standard deviation of V accurately. Hence, the standard deviation of V is ±0.00 cm3.

Answers
d.) the critical z-score for a left-tailed test at a 12% significance level is -0.45.
The critical z-score is the value on the standard normal distribution that separates the rejection region from the non-rejection region for a given level of significance (alpha). The critical z-score depends on the level of significance and the type of hypothesis test (one-tailed or two-tailed).
For a left-tailed test at a 12% significance level, the critical z-score can be found by looking up the z-score that corresponds to a cumulative probability of 0.12 in the standard normal distribution table. The closest value to 0.12 is 0.1190, which corresponds to a z-score of -1.18. Since this is a left-tailed test, we take the negative of the z-score to get the critical z-score, which is approximately -0.45. Therefore, option d is the correct statement.
