a. The substitution effect causes an increase of 10 units of good x due to the price change.   b. The income effect causes an increase of 10 units of good x due to the doubling of real income.



a. To calculate the substitution effect, we need to hold the utility constant. Since the price of good x decreased to $0.5, we can consider the new price ratio as 0.5:1 (x:y). Initially, with a budget of $10, we could purchase 10 units of good y. With the new price ratio, the consumer can buy 20 units of x for the same $10 budget. Therefore, the substitution effect leads to an increase of 20 - 10 = 10 units of x.

b. To calculate the income effect, we need to consider the change in real income caused by the price change. With the price of x decreasing to $0.5 and the consumer's disposable income remaining the same, the consumer's real income doubles. Since the utility function has an income elasticity of 1 for good x (as it appears in the utility function linearly), the consumer will allocate the same proportion of income to good x. Therefore, with the doubled real income, the consumer will purchase twice as much of good x.

Thus, the income effect leads to an increase of 10 units of x.

Step-by-step explanation:

Since lines n and p intersect, they must have different slopes.  Lets say they have slopes 2 and 4, as an example.  They will intersect.  Lines m and l are perpendicular to n and p, so their slopes will be the negative inverse of 2 and 4.  That gives them slopes of -(1/2) and -(1/4).  These slopes are different, so they will intersect.

The attached graph illustrates this intersection with lines having the above slopes.  Lines m and l intersect at (-1,1) in this example.  Lines m and l also intersect, off the graph at the top left.

Answer:

Step-by-step explanation:

Taylor polynomials of degree 2 and 3 centered at x = 0 for the function f(x) = 16tan(x) are:

P2(x) = 16x + 8x^2

P3(x) = 16x + 8x^2

To find the Taylor polynomials centered at x = 0 for the function f(x) = 16tan(x), we can use the Taylor series expansion for the tangent function and truncate it to the desired degree.

The Taylor series expansion for tangent function is:

tan(x) = x + (1/3)x^3 + (2/15)x^5 + (17/315)x^7 + ...

Using this expansion, we can find the Taylor polynomials of degree 2 and 3 centered at x = 0:

Degree 2 Taylor polynomial:

P2(x) = f(0) + f'(0)(x - 0) + (1/2!)f''(0)(x - 0)^2

= 16tan(0) + 16sec^2(0)(x - 0) + (1/2!)16sec^2(0)(x - 0)^2

= 0 + 16x + 8x^2

Degree 3 Taylor polynomial:

P3(x) = P2(x) + (1/3!)f'''(0)(x - 0)^3

= 0 + 16x + 8x^2 + (1/3!)(48sec^2(0)tan(0))(x - 0)^3

= 16x + 8x^2

Therefore, the Taylor polynomials of degree 2 and 3 centered at x = 0 for the function f(x) = 16tan(x) are:

P2(x) = 16x + 8x^2

P3(x) = 16x + 8x^2

Using Simple Speed formula,

To travel the distance of 75m with an airplane will need five gallons of fuel .

We have given that,

An airplane, fuel burn speed = 3 gallons of fuel per hour

ground speed of airplane = 45mph

distance = 75m

Speed = distance /time = 45 mph

=> 45 m distnce in one hour

fuel consumption of airplane = 3gallons/h

from above discussion we get,

fuel consumption for 45 m is equal to 3 gallons .

we have to calculate the quantity of fuel need to travel 75 m .

Now, 45 m distnce implies 3 gallons fuel consumption

1 m distance implies 3/45 gallons of fuel consumption

fuel consumption for 75 m =( 3/45)×75 = 5 gallons

Hence, 5 gallons fuel we need to travel 75 m .

Step-by-step explanation:

The inverse of the function h(x) = 3x² - 5, is r(x) = √[(x + 5)/3]

A function is said to have an inverse if it is both one-to-one and onto

From the question, we are given the function h(x) = 3x² - 5

we replace h(x) with y and make x the subject to arrive at the inverse r(x) as follows;

y = 3x² - 5

add 5 both sides

y + 5 = 3x² - 5 + 5

y + 5 = 3x²

also;

3x² = y + 5

divide through by 3

3x² = (y + 5)/3

x² = (y + 5)/3

take the square root of both sides

x = √[(x + 5)/3]

so;

r(x) = √[(x + 5)/3]

Therefore, the inverse of the function h(x) is derived by interchanging the value of x for y and r(x) = √[(x + 5)/3]

x = 30

Step-by-step explanation:

Put in proportions \(\frac{x}{45}\) = \(\frac{18}{27}\)

27x = 810.

The probability of the last digit being greater than 90 is approximately 0.2525, with a 95th percentile of 98.8037. The probability of the mean of 10 randomly chosen last digits being greater than 90 is approximately 0.0178.

a) The last digit of the student ID is 4. Therefore, X follows a normal distribution with a mean of 84 and a standard deviation of 9.

b) To find P(X > 90), we can use the standard normal distribution with the Z-score formula.

Z = (90 - 84) / 9 = 0.6667

Using a standard normal distribution table or a calculator, we find P(Z > 0.6667) ≈ 0.2525.

Therefore, P(X > 90) is approximately 0.2525.

c) To find the 95th percentile of X, we can use the standard normal distribution and find the Z-score corresponding to the cumulative probability of 0.95.

Using a standard normal distribution table or a calculator, we find the Z-score corresponding to a cumulative probability of 0.95 is approximately 1.645.

Now, we can calculate the 95th percentile of X as:

X = 84 + 1.645 * 9 ≈ 98.8037

Therefore, the 95th percentile of X is approximately 98.8037.

d) According to the Central Limit Theorem, when a large number of samples are taken, the sample mean follows a normal distribution regardless of the population distribution.

Given that 10 values are randomly chosen, the sample mean (X⁻) would also follow a normal distribution with a mean equal to the population mean (84) and a standard deviation equal to the population standard deviation divided by the square root of the sample size (9 / sqrt(10) ≈ 2.8461).

To find P(X⁻ > 90), we can use the standard normal distribution with the Z-score formula:

Z = (90 - 84) / 2.8461 ≈ 2.1092

Using a standard normal distribution table or a calculator, we find P(Z > 2.1092) ≈ 0.0178.

Therefore, P(X⁻ > 90) is approximately 0.0178.

The first ordered pair is (850, 162.65), indicating that at a price of $162.65 per ounce, the daily demand of Virbog is 850 ounces. The second ordered pair is (1450, 132.05), indicating that at a price of $132.05 per ounce, the daily demand of Virbog is 1450 ounces.

These ordered pairs represent the relationship between the quantity demanded and the price per ounce of Virbog. It shows how the demand for Virbog changes with respect to its price.

The first ordered pair indicates that as the price per ounce increases to $162.65, the quantity demanded decreases to 850 ounces. The second ordered pair indicates that as the price per ounce decreases to $132.05, the quantity demanded increases to 1450 ounces.

There are 7 degrees of freedom for the pooled-variance t-test.

To perform a pooled-variance t-test, we need to calculate the degrees of freedom. The formula for degrees of freedom in a pooled-variance t-test is:

\(\[\text{{df}} = n_1 + n_2 - 2\]\)

where \(\(n_1\)\) and \(\(n_2\)\) are the sample sizes of the two independent samples.

In this case, \(\(n_1 = 4\)\) and \(\(n_2 = 5\)\). Substituting these values into the formula, we get:

\(\[\text{{df}} = 4 + 5 - 2 = 7\]\)

In a pooled-variance t-test, we combine the sample variances from two independent samples to estimate the population variance. The degrees of freedom for this test are calculated using the formula \(df = n1 + n2 - 2\), where \(n_1\)and \(n_2\) are the sample sizes of the two independent samples.

To understand why the formula is \(df = n1 + n2 - 2\), we need to consider the concept of degrees of freedom. Degrees of freedom represent the number of independent pieces of information available to estimate a parameter. In the case of a pooled-variance t-test, we subtract 2 from the total sample sizes because we use two sample means to estimate the population means, thereby reducing the degrees of freedom by 2.

In this specific case, the sample sizes are \(n1 = 4\) and \(n2 = 5\). Plugging these values into the formula gives us \(df = 4 + 5 - 2 = 7\). Hence, there are 7 degrees of freedom for the pooled-variance t-test.

Therefore, there are 7 degrees of freedom for the pooled-variance t-test.
