\( { \cot^{2}x}(1 + \tan^{2}x) \\ = \frac{1}{ \tan^{2}x} (1 + \tan^{2}x)\)

\( = \frac{1}{ \tan^{2}x } + 1\)

\( = \frac{ \cos^{2} x }{ \sin^{2}x } + 1 = \frac{ \cos^{2}x + \sin^{2}x}{ \sin^{2} x } \)

\( = \frac{1}{ \sin^{2}x } = \csc^{2} x\)

The given system of equations is: 4x - 3y = 11 and 7x + 5y = 9. The solution to the system of equations is x = 2 and y = -1

To solve this system of equations, we can use the method of substitution or the method of elimination. Let's solve it using the method of elimination:

We can eliminate one variable by multiplying the first equation by 5 and the second equation by 3:

(5)(4x - 3y) = (5)(11)    ->   20x - 15y = 55

(3)(7x + 5y) = (3)(9)     ->   21x + 15y = 27

Now, we can add the two equations together:

(20x - 15y) + (21x + 15y) = 55 + 27

41x = 82

x = 2

Substituting the value of x back into the first equation:

4(2) - 3y = 11

8 - 3y = 11

-3y = 11 - 8

-3y = 3

y = -1

Therefore, the solution to the system of equations is x = 2 and y = -1.

The decision for this test at a .05 level of significance is not enough information to make a decision the correct answer is (d).

To make a decision for a hypothesis test, we compare the obtained test statistic (in this case, z = 1.80) with the critical value(s) based on the chosen level of significance (in this case, α = 0.05).

For a one-sample z test, if the obtained test statistic falls in the rejection region (i.e., beyond the critical value(s)), we reject the null hypothesis. Otherwise, if the obtained test statistic does not fall in the rejection region, we fail to reject the null hypothesis.

Without knowing the critical value(s) corresponding to a significance level of 0.05 and the directionality of the test (one-tailed or two-tailed), we cannot determine the decision for this test. Therefore, the correct answer is (d) There is not enough information to make a decision.

A cylindrical tank standing upright has radius 20cm. If the water is being drained at rate  25 cm³/s the tank level drops at rate 0.02 cm/s.

Recall the formula for the volume of a cylinder:

V = πr². h

Where:

r = radius of the base

h = height of the cylinder

Take the derivative with respect to t

dV/dt = πr². dh/dt

Substitute dV/dt = 25 cm³/s and r = 20 cm:

25 = π x 20² x dh/dt

dh/dt = 25 / (400π) = 0.02 cm/s

Therefore, the level of the cylindrical tank drops at rate 0.02 cm/s

A firm experiences increasing returns to scale if inputs are doubled and output more than doubles.

When the firm's output grows at a faster rate than the growth in inputs, increasing returns to scale result. In this case, the company experiences economies of scale, which makes it more effective as it grows its production.

The firm is able to boost productivity and efficiency as it expands its scale of operations if inputs are doubled and output more than doubles.

This can be ascribed to a number of things, including specialisation, labour division, the use of capital-intensive technology, discounts for bulk purchases, and spreading fixed costs over a higher output. Lower average costs per unit of output result in higher profitability and competitiveness for the company.

The firm gains a number of benefits from growing returns to scale. First off, it lets the company to benefit from cost savings brought about by economies of scale, allowing it to manufacture goods or services for less money per unit. This may enable more competitive pricing on the market or result in larger profit margins.

Second, raising returns to scale can result in better operational effectiveness and resource utilisation. As the company grows in size, it will be able to use resources more wisely and profit from production volume-related synergies.market prices that are competitive.

Let X be the percentage of students who passed in both Nepali and English. Then the percentage of students who failed in at least one of the subjects would be:

Percentage of students who failed in Nepali = 30%

Percentage of students who failed in English = 27%

Percentage of students who failed in both subjects = 15%

Therefore, the percentage of students who failed in at least one of the subjects would be:

30% + 27% - 15% = 42%

This means that the percentage of students who passed in both subjects would be:

100% - 42% = 58%

Therefore, 58% of students passed in both Nepali and English.

S₁₆ = 488

Step-by-step explanation:

the sum to n terms of an arithmetic sequence is

\(S_{n}\) = \(\frac{n}{2}\) [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

here a₁ = 8 and d = a₂ - a₁ = 11 - 8 = 3 , then

S₁₆ = \(\frac{16}{2}\) [ (2 × 8) + (15 × 3) ]

Answer:

p = 3, q = 1

Step-by-step explanation:

well, let's think about what (x - p)² actually is.

let's do the multiplication (what a square is) :

(x - p)(x - p) = x² - px - px + p² = x² - 2px + p²

now, we compare the theoretical equation to the actual equation :

x² - 6x + 8 = 0

x² - 2px + p² = q

x² = x² check

-6x = -2px

-6 = -2p

p = -6/-2 = 3

that gives us

x² - 6x + 9 = q

compare this to

x² - 6x + 8 = 0

we subtract the second equation from the first

x² - 6x + 9 = q

- x² - 6x + 8 = 0

------------------------

0 0 1 = q

The value of x is obtained as follows:

128º.

The measure of angle A is given as follows:

m < A = 132º.

For a parallelogram, the opposite angles are congruent, meaning that they have the same measure, hence the value of x is obtained as follows:

5x - 508 = x + 4.

4x = 512

x = 512/4

x = 128.

Then the measure of angle A is given as follows:

m < A = 5(128) - 508

m < A = 132º.

We are given a regression model: test score = 800 - 8(student-teacher ratio)

If the student-teacher ratio drops by 2, then the new ratio is (old ratio - 2).

So, the new predicted test score is:

test score = 800 - 8(new ratio)

          = 800 - 8(old ratio + (-2))

          = 800 - 8(old ratio) - 8(-2)

          = 800 - 8(old ratio) + 16

Therefore, the predicted effect on the test score is an increase of 16 points.

Answer:

Answer(s): 15m

20(m-0.25m)

Step-by-step explanation:

The standard normal curve, also known as the standard normal distribution or the z-distribution, is a specific probability distribution that follows a bell-shaped curve. The area under the standard normal curve to the right of z = 3 is approximately 0.0013.

For the area under the standard normal curve to the right of z = 3, we need to calculate the cumulative probability from z = 3 to positive infinity.

The standard normal distribution, also known as the z-distribution, has a mean of 0 and a standard deviation of 1. It is a symmetric bell-shaped curve that represents the distribution of standard scores or z-scores.

Using statistical tables or software, we can find the cumulative probability associated with z = 3, which represents the area under the curve to the left of z = 3.

The cumulative probability for z = 3 is approximately 0.9987.

For the area to the right of z = 3, we subtract the cumulative probability from 1.

Therefore, the area to the right of z = 3 is approximately 1 - 0.9987 = 0.0013.

In conclusion, the area under the standard normal curve to the right of z = 3 is approximately 0.0013.

This means that the probability of randomly selecting a value from the standard normal distribution that is greater than 3 is approximately 0.0013 or 0.13%.

A hypothesis is an educated guess about a phenomenon that can be tested through experimentation or observation. The null hypothesis is the hypothesis that nothing is happening, and the alternative hypothesis is the hypothesis that there is an effect or difference. Reasonable doubt about a null hypothesis can be raised by finding evidence that contradicts it. A p-value is the probability that the results obtained in a study or experiment occurred by chance alone.

After analyzing a set of data, if the results support a hypothesis, this does not prove the hypothesis is true. This means the hypothesis is consistent with the data but further evidence or experimentation must be done to truly prove the hypothesis. After analyzing a set of data, if the results are inconsistent with a hypothesis, this does not prove the hypothesis is false. It could be due to chance or an inadequately tested hypothesis.

The reasoning of hypothesis testing is to determine if the results of a study or experiment support the null hypothesis or alternative hypothesis. A two-sided alternative hypothesis is when the difference between two groups is tested to be either greater or lesser than the reference value, whereas a one-sided alternative hypothesis tests the difference to be only greater or lesser than the reference value. A one-sided test is more conservative than a two-sided test as the former has a higher risk of making a type II error. The size of the effect when testing a hypothesis can be measured by the power of the test and the magnitude of the effect.
