As a result, the shaded region's area sector is **10.62 cm² cm.²

What is a sector?

A sector is a section of a circle in geometry that is bounded by two radii and an arc. It is a pie-shaped portion of a circle that touches the circle's center, has two straight edges (the two radius lines), and a curved edge created by the arc.

Arc Length = r is the formula for the arc length of a circle,

where is the radius of the circle and r is the radian measurement of the arc (or central angle).

The formula for arc length, L = r *, can be used to determine the value of zero. L is the length of the arc, r is the radius of the circle, and is the centre angle in radians. We can deduce from the facts provided that PQ equals 2 * OP.

Also obvious is that OR = 4 cm. We can claim that PQ = 2 * OR = 8cm because PQ is twice as long as OP. Now, we can calculate's value using the formula:

L = r * θ 8 = 4θ θ = 2

Consequently, = 2 radians.

We must know the length of arc RS in order to calculate the size of the shaded zone. PQ is twice RS, as we are aware. RS = PQ/2, which equals 4 cm. Now, we may apply the area of a formula.We may now apply the formula A = (1/2) * r² *, where A is the sector's area, r is the circle's radius, and is the centre angle in radians.

Sector PQR area equals (1/2) * OR2 * sector PQR area equals (1/2) * 16 * 2 sector PQR area equals (16)

Sector PSR area equals (1/2) * OR²2 * Sector PSR area equals (1/2) * 16 * π/3 Sector PSR area equals (8)/3

Sector PQR minus Sector PSR is equal to the area of the shaded region. Area of the shaded area is 16 - (8π)/3. Shaded area size: 10.62 cm²

Answer: a) To count the number of one-to-one functions from the set {1, 2,...,n} to the set {0, 1}, we can use the formula for the number of permutations of n distinct objects, which is n!.

However, since we are only considering one-to-one functions, we can only choose 0 or 1 for the image of each element of the domain. The first element can be assigned 2 choices, the second can be assigned 1 of the remaining 2 choices, the third can be assigned 1 of the remaining 1 choice, and so on. Therefore, the number of one-to-one functions from {1, 2,...,n} to {0, 1} is:

2 × 1 × 1 × ... × 1 = 2^(n-1)

b) To count the number of functions that assign 0 to both 1 and n, we can treat the remaining elements {2, 3,...,n-1} as a new set and count the number of functions from this set to {0, 1}. This is the same problem as in part (a), but with n-2 elements instead of n. Therefore, the number of functions from {1, 2,...,n} to {0, 1} that assign 0 to both 1 and n is:

2^(n-3)

c) To count the number of functions that assign 1 to exactly one of the positive integers less than n, we can choose which element of the domain is assigned 1 in n ways. The remaining elements can be assigned 0 or 1 independently, for a total of 2^(n-1) choices. Therefore, the number of functions from {1, 2,...,n} to {0, 1} that assign 1 to exactly one of the positive integers less than n is:

n × 2^(n-1)

The probability of drawing a red card, placing it back in the deck, and drawing another red card is 1/4.

According to the given question.

Total number of cards in a deck is 52.

As we know that total number of red cards in a well shuffled deck is 26.

Since, Eric first draws a red card, places it back in the deck, shuffles the deck, and then draws another card. Which means there is a replacement of cards.

So, the probability of drawing the first card is red = 26/52 = 1/2

And the probability of drawing the another card is red = 26/52 = 1/2

Therefore,

The probability of drawing a red card, placing it back in the deck, and drawing another red card

= 1/2  × 1/2

= 1/4

Hence, the probability of drawing a red card, placing it back in the deck, and drawing another red card is 1/4.

Your answer is :-skew-symmetric.

We will show that if A is any n x n matrix, then (i) AAT is symmetric, and (ii) A - AT is skew-symmetric.

(i) To show that AAT is symmetric, we need to prove that (AAT)T = AAT. Here's the step-by-step explanation:

1. Compute the transpose of AAT, denoted as (AAT)T.
2. Using the reverse rule of transposes, we get (AAT)T = (AT)T * AT.
3. Since the transpose of a transpose is the original matrix, we have (AT)T = A.
4. Therefore, (AAT)T = A * AT = AAT, proving that AAT is symmetric.

(ii) To show that A - AT is skew-symmetric, we need to prove that (A - AT)T = -(A - AT). Here's the step-by-step explanation:

1. Compute the transpose of A - AT, denoted as (A - AT)T.
2. Using the properties of transposes, we get (A - AT)T = AT - A.
3. Now, we can observe that AT - A is the negation of A - AT, which is -(A - AT).
4. Therefore, (A - AT)T = -(A - AT), proving that A - AT is skew-symmetric.

A correlational research design investigates relationship between variables without the researches controlling or manipulation any of them.

Correlational analysis is statistical method that is used to discover if there is a relationship between two variables/dataset, and how strong that relationship may be.

A correlation reflects the strength and direction of the relationship between two variables. The direction of a correlation can be either positive or negative.

Correlational research is ideal gathering data quickly from natural settings. They helps you generalize your findings to real-life situations in an externally valid way.

Correlation is also used to establish the reliability and validity of measurements. A positive correlation is a relationship between two variable s in which bothe variables move in the same direction. A negative correlation is a relationship between two variables in which as increase in one variable is associated with a decrease in the other. A zero correlation exist when there is no relationship between two variables.

Distance is described as a numerical or occasionally qualitative measurement of how far apart objects or points are.

we have then equation that:

To find y′(−10) for the function y(x) = √−7x−5 using the definition of a derivative, we need to evaluate the derivative at x = -10.

The derivative of a function represents its rate of change at a specific point. To find the derivative using the definition, we can start by expressing the given function as y(x) = (-7x - 5)^(1/2). We want to find y′(−10), which corresponds to the derivative of y(x) at x = -10.

Using the definition of a derivative, we calculate the derivative as follows:

y'(x) = lim(h→0) [y(x + h) - y(x)] / h,

where h represents a small change in x. Substituting the values into the derivative definition, we have:

y'(x) = lim(h→0) [(√(-7(x + h) - 5) - √(-7x - 5)) / h].

Next, we substitute x = -10 into this expression:

y'(-10) = lim(h→0) [(√(-7(-10 + h) - 5) - √(-7(-10) - 5)) / h].

By evaluating this limit, we can find the value of y′(−10). Note that further numerical calculations are required to obtain the specific value.
