The terminal point of 7π/6 is (-√3/2, 1/2) when the reference angle for 7π/6 is π/6.

A terminal is a straight line that has been turned around a point on another line to generate an angle measured clockwise or counterclockwise. A 90° angle is formed by the terminal side of the 90° angle and the x-axis. In this scenario, the reference angle is the same as the original angle. In reality, each angle between 0° and 90° is equal to its reference angle.

Here,

We have any point (x, y) on the unit circle of radius ‘r’ centered at origin which is (rcosθ, rsinθ)/(rcost, rsint).

Here, t = -7π/6 and r = 1

∴ Required point (x, y) = (rcost, rsint)

= [(1)cos (-7π/6), (1)sin(-7π/6)]

= [cos 7π/6, -sin7π/6] [∵ cos(-θ) = cosθ and sin (-θ) = -sinθ]

Using allied angles,

cos(7π/6) = cos [π + (π/6)] = - cos(π/6) = -√3/2

-sin(7π/6) = -sin [π+ (π/6)] = -[-sin(π/6)] = 1/2

Therefore, the required point is (-√3/2, 1/2)when the reference angle for 7pi/6 is pi/6.

The type of sampling used in this scenario is a multistage cluster sampling. In this type the population is divided into clusters or groups.

In multistage cluster sampling, the population is divided into clusters or groups, and a sample is taken from each cluster. In this case, the clusters are the states, and a simple random sample of four states is selected.

Within each selected state, another level of sampling occurs where two colleges or universities are randomly selected from each state. This forms the second stage of sampling.

Finally, from each of the eight selected colleges or universities, a simple random sample of 20 undergraduates is taken. This forms the third stage of sampling.

By combining these stages, a final sample of 160 undergraduates is obtained.

Multistage cluster sampling is commonly used when the population is large and geographically dispersed. It offers a practical approach to obtain a representative sample by selecting clusters at different stages, which helps to reduce time, cost, and logistical challenges.

The probability of getting a 7  \(\frac{1}{13}\) and a black card is \(\frac{1}{2}\).

What is a Probability?

Mathematical explanations of the likelihood that an event will occur or that a statement is true are referred to as probabilities.

A number between 0 and 1 represents the likelihood of an event, with 0 generally denoting impossibility and 1 denoting certainty. It is more likely that an event will occur if its probability is higher.

Probability theory, which is widely used in fields of study like statistics, mathematics, science, finance, gambling, artificial intelligence, machine learning, computer science, game theory, and philosophy, has given these ideas an axiomatic mathematical formalization.

The correlation is a significant non-zero value.

The number of samples is n.

n = 25

The correlation of the coefficient is r.

r = -0.40

When correlation is significant,

\(H _{0} : p = 0\)

When correlation is non-zero,

\(H _{ \alpha } : p ≠0\)

The test statistic is,

\(TS = \frac{r \times \sqrt{n - 2} }{ \sqrt{1 - r {}^{2} } } \)

\( = \frac{0.4 \times \sqrt{25 - 2} }{ \sqrt{1 - ( - 0.4) ^{2} } } \)

The value of q is -27.

Recall Vieta's Formulas, which state that for a quadratic equation \(ax^2\) + bx + c = 0 with zeroes alpha and beta, the sum of the zeroes is equal to -b/a, and the product of the zeroes is equal to c/a.

In our equation \(x^2\) - 3x + q, the sum of the zeroes alpha and beta is -(-3)/1 = 3.

We are given that 2 alpha + 3 beta = 15. Substitute alpha = (15 - 3 beta)/2 into the equation.

Replace the value of alpha in the sum of zeroes equation: (15 - 3 beta)/2 + beta = 3.

Simplify the equation by multiplying both sides by 2: 15 - 3 beta + 2 beta = 6.

Combine like terms: 15 - beta = 6.

Subtract 15 from both sides: -beta = -9.

Multiply both sides by -1 to solve for beta: beta = 9.

Substitute the value of beta into the sum of zeroes equation: alpha = (15 - 3 * 9)/2 = -3.

Since we have the values of alpha and beta, we can find q using the product of the zeroes formula: q = alpha * beta = -3 * 9 = -27.

Answer:

Step-by-step explanation:

Given the initial expression sin(θ) + cos(θ) * cos(θ) * (1 - cos(θ)), we simplified it to sin(θ) + cos²(θ) - cos³(θ).

Given the expression:
sin(θ) + cos(θ) * cos(θ) * (1 - cos(θ))
Let's simplify this expression step by step:
1. First, recognize that cos(θ) * cos(θ) can be written as cos²(θ). So, the expression becomes:
sin(θ) + cos²(θ) * (1 - cos(θ))
2. Next, we'll distribute cos²(θ) to both terms inside the parentheses:
sin(θ) + cos²(θ) - cos³(θ)
At this point, we have simplified the expression as much as possible. The final expression is:
sin(θ) + cos²(θ) - cos³(θ)
In summary, given the initial expression sin(θ) + cos(θ) * cos(θ) * (1 - cos(θ)), we simplified it to sin(θ) + cos²(θ) - cos³(θ). Remember that this is a general expression and its specific value depends on the angle θ.

The functions are given as;

f o g(x) = 2x³ - 18

g ∘ f = 8x³ - 9

The domain is the sum of all real number (-∞, ∞)

From the information given, we have that;

f(x) = 2 x

g(x) = x³ - 9

To determine the composite function,

f o g(x), we have to substitute the value of x as g(x) in the function f(x), then, we have;

f o g(x) = 2(x³ - 9)

expand the bracket, we have;

f o g(x) = 2x³ - 18

To determine the composite function, we have;

g ∘ f(x) = (2x)³ - 9

expand the bracket

g ∘ f = 8x³ - 9

The equation that represents h(x) is h(x) = (f(x))(g(x)).

To determine which equation represents h(x), we need to analyze the given table and understand the relationship between the functions f(x), g(x), and h(x).

Since h(x) represents the output values obtained by multiplying f(x) and g(x), we should look for values in the table where h(x) is the product of the corresponding values of f(x) and g(x).

Let's examine the table and compare the values:

x | f(x) | g(x) | h(x)

1 | 3 | 4 | 12

2 | 5 | 2 | 10

3 | 2 | 6 | 12

From the table, we can see that the values in the h(x) column are the products of the corresponding values in the f(x) and g(x) columns. Therefore, the equation that represents h(x) is h(x) = (f(x))(g(x)).
