Answer:

C. The product of two irrational numbers is irrational.

Example: √3•√3=3

Answer:

Step-by-step explanation:a) To find the price of the car before VAT, we need to first calculate the percentage of VAT included in the price:

VAT% = (VAT / Total Price) x 100

where VAT% is the percentage of VAT, VAT is the value of VAT, and Total Price is the price of the car including VAT.

From the given information, we have:

Total Price = Birr 5,000,000

VAT% = 15% (assuming a VAT rate of 15% in Ethiopia)

Therefore, we can solve for the value of the car before VAT as follows:

Total Price = Car Price + VAT

Birr 5,000,000 = Car Price + 0.15Car Price

Birr 5,000,000 = 1.15Car Price

Car Price = Birr 4,347,826.09

So the price of the car before VAT is Birr 4,347,826.09.

b) To find the value of VAT, we can use the same formula as above and solve for VAT:

Total Price = Car Price + VAT

Birr 5,000,000 = Birr 4,347,826.09 + VAT

VAT = Birr 652,173.91

Therefore, the value of VAT is Birr 652,173.91.

The expression in terms of π that represents the area of the shaded part of ⊙R is 3πR²/4, obtained by subtracting the area of the smaller circle from the larger circle.

To find the area of circle of the shaded part of ⊙R, we need to subtract the area of the smaller circle from the area of the larger circle.

The area of a circle is given by the formula A = πr², where r is the radius of the circle.

Let the radius of the larger circle be R and the radius of the smaller circle be r. Then the area of the shaded part can be expressed as:

A(shaded) = A(large circle) - A(small circle)

= πR² - πr²

We can simplify this expression further by noticing that the radius of the smaller circle is half the radius of the larger circle, so r = R/2. Substituting this into the equation gives:

A(shaded) = πR² - π(R/2)²

= πR² - πR²/4

= 3πR²/4

Therefore, the area of the shaded part of ⊙R can be expressed as 3πR²/4. This expression represents the difference in the area between the larger and smaller circles, which gives us the area of the shaded region.

Answer is 64.05% probability that if we chose a student at random

To find the probability that a randomly chosen student would not like the school lunches, we need to find the complement of the probability that they do like the school lunches.

The proportion of 9th graders in the sample is 45%, so the proportion of 10th graders is 100% - 45% = 55%.

Of the 9th graders, 31% said they liked the school lunches, so the proportion that did not like them is 100% - 31% = 69%.

Of the 10th graders, 42% said they liked the school lunches, so the proportion that did not like them is 100% - 42% = 58%.

So, the probability that a randomly chosen student would not like the school lunches is:

(0.45 * 0.69) + (0.55 * 0.58) = 0.6405 or 64.05% (rounded to two decimal places).

Therefore, there is a 64.05% probability that if we chose a student at random, they would not like the school lunches.

The powerset of M can be written as P(M) = {(1, 2), (1, 4), (2, 1), (2, 4), (2, 4, 1), (1, 4), (4, 2}, {}}.

Given that, M = {x: x² - 5x + 2x + 8 = 0}

This is a quadratic equation and it can be written in the form of (x - a)(x - b) = 0, where a and b are the roots of the equation.

Substituting x² - 5x + 2x + 8 = 0 in (x - a)(x - b) = 0, we get

(x - a)(x - b) = (x - (-3))(x - 5) = 0

Therefore, the roots of the equation are a = –3 and b = 5.

Now, the powerset of M can be written as P(M) = {(1, 2), (1, 4), (2, 1), (2, 4), (2, 4, 1), (1, 4), (4, 2}, {}}.

Here,

(1, 2) represents the set containing only the root ‘–3’,

(2, 1) represents the set containing only the root ‘5’,

(2, 4) represents the set containing both the roots

Therefore, the powerset of M can be written as P(M) = {(1, 2), (1, 4), (2, 1), (2, 4), (2, 4, 1), (1, 4), (4, 2}, {}}.

The z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is obtained by the equation presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean and the standard deviation are given as follows:

[tex]\mu = 115, \sigma = 11[/tex]

The proportion of games with scores between 93 and 142 is the p-value of Z when X = 142 subtracted by the p-value of Z when X = 93, hence:

Z = (142 - 115)/11

Z = 2.45

Z = 2.45 has a p-value of 0.992.

Z = (93 - 115)/11

We can use the formula for the area of a sector to find the area of sector $LMN$

The area of a sector with central angle $\theta$ in a circle with radius $r$ is given by:

$A = \frac{\theta}{360^\circ} \pi r^2$

In this case, we know that $m\angle LMN = 66^\circ$ and $LM = 19$ units, so the radius of circle M is half of the diagonal of the rectangle formed by $LM$ and $MN$. Using the Pythagorean theorem, we can find the length of $MN$:

$MN^2 = LM^2 + LN^2 = LM^2 + LM^2 = 2LM^2$

$MN = \sqrt{2} LM = \sqrt{2} \cdot 19$

So the radius of circle M is $r = \frac{1}{2}MN = \frac{1}{2}\sqrt{2} \cdot 19$

Now we can use the formula for the area of a sector to find the area of sector $LMN$:

$A = \frac{m\angle LMN}{360^\circ} \pi r^2 = \frac{66^\circ}{360^\circ} \pi \left(\frac{1}{2}\sqrt{2} \cdot 19\right)^2 \approx \boxed{90.89}$ square units (rounded to the nearest hundredth).

b) The function rule for Coaster City is, f(x) = 5x + 7.50, where x is the number of roller coaster ridden and f(x) is total cost.

c) The function rule for Virtual Reality Lan is, f(x) = 3x + 10, where f(x) is total cost and x is the number reality rides ridden.

(a) Let f(x) = ax +b be the function which represents the total cost of Big Wave Park where x represents the number of taken ride.

We can see that f(2) = 10; f(4) = 15 and f(6) = 20.

Therefore, 2a + b = 10 and 4a + b = 15

So, 2(2a + b) - (4a + b) = 2*10 - 15

4a + 2b - 4a - b = 20 - 15

b = 5

Now, f(6) = 20

6a + b = 20

6a + 5 = 20 [putting the value of 'b']

6a = 20 - 5 = 15

a = 15/6 = 5/2 = 2.5

Hence, the function rule for Big Wave Waterpark is, f(x) = 2.5x + 5.

(b) The function rule for Coaster city is, f(x) = 5x + 7.50, where x is the number of roller coaster ridden.

(c) Let the total cost for Virtual Reality Lan is, f(x) = cx + d, where x is the number reality rides ridden.

From the given graph we can see that, f(10) = 40; f(20) = 70; f(30) = 100.

So, 10c + d= 40 ........... (i)

20c + d = 70 ............... (ii)

Solving (i) and (ii) we get,

2(10c + d) - (20c + d) = 2*40 - 70

20c + 2d - 20c - d = 80 - 70

d = 10

So putting the value d = 10 in f(30) = 100 we get,

30c + 10 = 100

30c = 100 - 10 = 90

c = 90/30 = 3

So the function rule is, f(x) = 3x + 10.

The calculated t-value of 1.100 is less than the critical t-value of 2.718, we fail to reject the null hypothesis.

To test the hypothesis that regular physical exercise improves academic achievement, we will conduct a two-sample t-test for independent samples. The null hypothesis is that there is no difference in the mean academic achievement scores between the treatment group (physical exercise) and the control group (no physical exercise).

Let's calculate the mean and standard deviation for each group:

Treatment group (physical exercise):

mean = (4 + 2.67 + 3.65 + 2.11 + 3.21 + 3.6) / 6 = 3.3833

standard deviation = 0.7589

Control group (no physical exercise):

mean = (3.75 + 2.74 + 3.42 + 1.67 + 3 + 3.25 + 2.65) / 7 = 3.0071

standard deviation = 0.7037

We can now calculate the t-statistic:

t = (3.3833 - 3.0071) / sqrt((0.7589^2 / 6) + (0.7037^2 / 7)) = 1.100

The degrees of freedom for this test are 6 + 7 - 2 = 11 (assuming equal variances).

Using a t-table or a t-distribution calculator with 11 degrees of freedom and a significance level of 0.01, we find that the critical t-value is ±2.718.

Since the calculated t-value of 1.100 is less than the critical t-value of 2.718, we fail to reject the null hypothesis. We do not have enough evidence to conclude that regular physical exercise improves academic achievement.

The p-value for this test can be calculated as the probability of getting a t-value as extreme as 1.100, assuming the null hypothesis is true. Using a t-distribution calculator with 11 degrees of freedom, we find that the p-value is 0.294 (rounded to three decimal places).

Since the test result is not statistically significant (p > 0.01), we do not need to report an effect size using Cohen's d.

This test result could be reported in the literature as follows: "A two-sample t-test for independent samples was conducted to examine the effect of regular physical exercise on academic achievement, while controlling for academic aptitude. Six pairs of college students with similar GPAs were randomly assigned to either a treatment group that attended daily exercise classes or a control group. The mean academic achievement score for the treatment group was 3.3833 with a standard deviation of 0.7589, while the mean academic achievement score for the control group was 3.0071 with a standard deviation of 0.7037. The t-test result was not statistically significant (t(11) = 1.100, p = 0.294), indicating that there is not enough evidence to conclude that regular physical exercise improves academic achievement."

If every of the unique cows was producing 12.8 liters of milk in keeping with day, and there had been "x" cows, then the entire amount of milk produced by means of the original cows could be:

12.8x liters per day

After the adjustments, the farmer has 60 more cows and all cows produce 15 liters of milk per day. So, the full amount of milk produced with the aid of all cows after the modifications would be:

15(x + 60) liters per day

we're told that the new milk production is 1340 liters more according to day than before the changes. So, we can set up an linear equation:

15(x + 60) = 12.8x + 1340

Simplifying the equation, we get:

15x + 900 = 12.8x + 1340

2.2x = 440

x = 200

therefore, there were at first 200 cows on the farm. After the changes, the full number of cows would be:

To express the volume of D as an iterated triple integral in (a) spherical, (b) cylindrical coordinates, we can use the following formulas:

(a) Spherical Coordinates:

We know that the equation of a sphere with radius 6 units is given by:

x^2 + y^2 + z^2 = 6^2

The equation of the plane 3 units from the center of the sphere is given by:

z = 3

To find the equation of the smaller cap cut from the sphere by this plane, we need to find the upper limit of the radial coordinate. This can be found by solving the equation of the sphere for z, and substituting z = 3:

z = sqrt(6^2 - x^2 - y^2)
3 = sqrt(6^2 - x^2 - y^2)
x^2 + y^2 = 27

Thus, the smaller cap D is the region of the sphere bounded by the plane z = 3 and the surface x^2 + y^2 + z^2 = 6^2, with x^2 + y^2 <= 27.

To express the volume of D as an iterated triple integral in spherical coordinates, we can use the following limits:

0 <= r <= sqrt(27)
0 <= θ <= 2π
arcsin(3/6) <= φ <= π

The volume of D can be expressed as the triple integral:

∫∫∫ D  r^2 sin φ dr dφ dθ

(b) Cylindrical Coordinates:

To express the volume of D as an iterated triple integral in cylindrical coordinates, we can use the following limits:

0 <= r <= sqrt(27)
0 <= θ <= 2π
3 <= z <= sqrt(6^2 - r^2)

The volume of D can be expressed as the triple integral:

∫∫∫ D  r dz dr dθ
(a) In spherical coordinates, the volume element is given by dV = ρ²sin(φ)dρdθdφ. To find the limits of integration, note that the radius of the smaller cap ranges from 0 to 3 units, the angle θ ranges from 0 to 2π, and the angle φ ranges from 0 to φ₀, where φ₀ is the angle between the plane and the line from the sphere's center to the plane's intersection with the sphere.

Using the cosine rule, we can find φ₀ as follows:
cos(φ₀) = (6² + 3² - 3²) / (2 × 6 × 3) = 1/2
φ₀ = π/3

Now, we can express the volume of D as an iterated triple integral in spherical coordinates:
∫(ρ=0 to 3) ∫(θ=0 to 2π) ∫(φ=0 to π/3) ρ²sin(φ)dρdθdφ

(b) In cylindrical coordinates, the volume element is given by dV = rdzdrdθ. To find the limits of integration, note that the height z ranges from 3 to 6 units, the radius r ranges from 0 to √((6 - z)²), and the angle θ ranges from 0 to 2π.

Now, we can express the volume of D as an iterated triple integral in cylindrical coordinates:
∫(z=3 to 6) ∫(θ=0 to 2π) ∫(r=0 to √((6 - z)²)) rdzdrdθ

The given expression x²y − 7xy + xyz is a 3rd degree polynomial.

To classify it by degree and term, let's first determine the degree of each term:

1. x²y: The degree is the sum of the exponents of the variables (x and y). Here, the degree is 2 (from x²) + 1 (from y) = 3.
2. 7xy: The degree is 1 (from x) + 1 (from y) = 2.
3. xyz: The degree is 1 (from x) + 1 (from y) + 1 (from z) = 3.

Now, we can classify the expression:

- Degree: Since the highest degree among the terms is 3, the expression is a 3rd-degree polynomial.
- Term: There are three terms in the expression, so it is a trinomial.

In summary, the given expression, x²y − 7xy + xyz, is a 3rd-degree trinomial.

In the given  isosceles triangle, the measure of angle G is 74 degrees.

In the given problem, we are dealing with an isosceles triangle where angle G measures 74 degrees. It is mentioned that EF and FG are congruent, indicating that triangle EFG is isosceles.

Since EFG is an isosceles triangle, we can conclude that angles E and G are congruent. Therefore, we can set the measure of angle E equal to the measure of angle G and solve for x.

By setting 4x + 50 (measure of angle E) equal to 14x + 30 (measure of angle G), we have the equation 4x + 50 = 14x + 30.

Solving for x, we find that x = 2.

Now that we have the value of x, we can substitute it into each angle measure to determine their values.

The measure of angle E (mE) is given by 4x + 50, which becomes 4(2) + 50 = 58 degrees.

The measure of angle F (mF) is given by 2x + 60, which becomes 2(2) + 60 = 64 degrees.

Finally, the measure of angle G (mG) is already known to be 74 degrees.

Therefore, the measures of the angles in the isosceles triangle are: mE = 58 degrees, mF = 64 degrees, and mG = 74 degrees.

By understanding the properties of isosceles triangles and utilizing algebraic equations, we can determine the measures of the angles in the given triangle.

Both Denise and Kristal are correct. The expression "p - 0.25p" is equivalent to "0.75p," which represents the sale price after a 25% markdown. Therefore, option C is the correct answer.

Denise's expression, "p - 0.25p," represents the original price (p) minus the 25% markdown (0.25p). This simplifies to 0.75p, which is indeed the sale price.

On the other hand, Kristal's expression, "0.75p," directly represents the sale price after applying a 25% discount. This expression skips the intermediate step of subtracting the markdown from the original price.

Both expressions, "p - 0.25p" and "0.75p," yield the same result, which is the sale price after a 25% markdown. Therefore, both Denise and Kristal are correct in their calculations.

The choice between the two expressions comes down to personal preference or convenience. Some individuals may find it easier to directly calculate the sale price using a percentage of the original price, while others may prefer subtracting the markdown amount from the original price.

David's net worth: 86,329.95

To calculate David's new net worth, we need to add the increase in assets and subtract the decrease in liabilities from his current net worth.

New assets value = 62,784.24 + 2,784.89 = 65,569.13

New liabilities value = David's current net worth - his current assets value

New liabilities value = 45,765.78 - 62,784.24 = -17,018.46

Since his liabilities have decreased by 3,742.36, we need to subtract this value from the new liabilities value:

New liabilities value = -17,018.46 - 3,742.36 = -20,760.82

Now we can calculate his new net worth by subtracting his new liabilities value from his new assets value:

New net worth = 65,569.13 - (-20,760.82) = 86,329.95

Therefore, David's new net worth is 86,329.95.
