To find the value of the linear correlation coefficient r, you need to have two variables and their corresponding data sets.

The formula for the linear correlation coefficient r is as follows:

\($$r = \frac{n\sum xy - \sum x\sum y}{\sqrt{n\sum x^2 - (\sum x)^2} \sqrt{n\sum y^2 - (\sum y)^2}}$$\)

Where n is the number of data points, x and y are the two variables, and Σ represents the sum of the data. To calculate r, you need to calculate six sums: Σx, Σy, Σxy, Σx2, Σy2, and n.Let's go through an example.

Suppose you have the following data sets for two variables x and y:

$$x: 1, 2, 3, 4, 5$$$$

y: 2, 4, 6, 8, 10$$

First, calculate the six sums:

$$\Sigma x = 1 + 2 + 3 + 4 + 5 = 15$$$$\Sigma y = 2 + 4 + 6 + 8 + 10 = 30$$$$\Sigma xy = (1)(2) + (2)(4) + (3)(6) + (4)(8) + (5)(10) = 110$$$$\Sigma x^2 = (1)^2 + (2)^2 + (3)^2 + (4)^2 + (5)^2 = 55$$$$\Sigma y^2 = (2)^2 + (4)^2 + (6)^2 + (8)^2 + (10)^2 = 220$$$$n = 5$$

Now, substitute these values into the formula for r:

$$r = \frac{(5)(110) - (15)(30)}{\sqrt{(5)(55) - (15)^2} \sqrt{(5)(220) - (30)^2}}$$

$$r = \frac{550 - 450}{\sqrt{275 - 225} \sqrt{1100 - 900}}$$

$$r = \frac{100}{\sqrt{50} \sqrt{200}}$$

$$r = \frac{100}{\sqrt{10000}}$$

$$r = \frac{100}{100}$$

$$r = 1$$

Therefore, the linear correlation coefficient r is 1.

This indicates a perfect positive linear relationship between x and y.

To find the value of the linear correlation coefficient r, you need to first calculate the covariance and standard deviation of the two variables.

The formula for the linear correlation coefficient r is:

\($$r = \frac{\text{cov}(X,Y)}{\sigma_X \sigma_Y}$$\)

where cov(X,Y) is the covariance of X and Y, σX is the standard deviation of X, and σY is the standard deviation of Y.

Here are the steps to calculate the linear correlation coefficient r:

Step 1: Calculate the mean of X and Y.

\($$ \begin{aligned}\overline X &= \frac{1}{n}\sum_{i=1}^{n} X_i\\ \overline Y &= \frac{1}{n}\sum_{i=1}^{n} Y_i\end{aligned} $$\)

Step 2: Calculate the deviations of X and Y from their respective means. \($$\begin{aligned}d_i(X) &= X_i - \overline X\\ d_i(Y) &= Y_i - \overline Y\end{aligned}$$\)

Step 3: Calculate the sum of the products of the deviations.

\($$S_{xy} = \sum_{i=1}^{n} d_i(X) d_i(Y)$$\)

Step 4: Calculate the covariance of X and Y.

\($$ \text{cov}(X,Y) = \frac{S_{xy}}{n-1} $$\)

Step 5: Calculate the standard deviation of X and Y.

\($$ \begin{aligned}\sigma_X &= \sqrt{\frac{\sum_{i=1}^{n} (X_i - \overline X)^2}{n-1}}\\ \sigma_Y &= \sqrt{\frac{\sum_{i=1}^{n} (Y_i - \overline Y)^2}{n-1}}\end{aligned}$$\)

Step 6: Calculate the linear correlation coefficient r.

\($$r = \frac{\text{cov}(X,Y)}{\sigma_X \sigma_Y}$$\)

Answer:

f(x) = 3

Step-by-step explanation:

f(0) = 3  means you have the ordered pair (0, 3)

f(-6) = 3  means you have the ordered pair (-6, 3)

Form this point, you can look at the ordered pair and see that the y values are the same but the x values are difference.  This is a line with slope = 0 and the graph of the line is horizonal .  

But if you need more explanation see  below.

1. Find the slope using the ordered pair above

  slope = (3 - 3)/ (-6 - 0) = 0/-6 = 0  so the slope = 0

2.   Find the y intercept (b) by using the slope intercept formula: y = mx + b

    y = mx + b

     3 = 0(0) + b

      3 = b

equation of the line: y = 0x + 3;  y = 3 remember y = f(x)

so  f(x) = 3

The game will cost Arnold for $8.99.

How does subtraction work?

Mathematical operation is subtraction. It is employed to eliminate terms or expression's objects.

Given, a video game costs $14.99 at Arnold's.

40% of the sales price

= 40 x 14.99 / 100

= 5.996,

which equals 6, round.

The game is marked up by Arnold's at 40% of the asking price. that is 6,

40% of the selling price equals the selling cost minus Arnold's game costs.

Cost of the game to Arnold: 6 = 14.99

the game's price to Arnold plus 6 equals $14.99

making use of the subtraction operation,

The game cost Arnold $8.99.

Arnold will pay $8.99 for the game as a result.

The lifting force if the speed is 220 miles per hour is F' = 708.53 N.

The force of light, or simply light, is the sum of all forces on an object that cause the object to move perpendicular to the direction of flow.

The most common type of lift is the wing lift. But there are many other common uses, such as propellers on airplanes and ships, rotors on helicopters, fan blades, sails on sailboats, and wind turbines.

We have,

The lifting force, F, exerted on an airplane wing varies jointly as the area, A, of the wing's surface and the square of the plane's velocity, v. It, means that,

\(F=kAv^{2}\)

Where

k is constant

If, A = 190 Ft², v = 220 mph, F = 950 pounds

Now, find k first from the above data. So,

    \(k=\frac{F}{Av^{2} }\)

⇒ \(k=\frac{950}{190* (220)^2}\)

⇒ k = 0.0001033

It is required to find the lifting force on the wing if the plane slows down to 190 miles per hour.

Let F' is a new force. So,

    F' = 0.0001033 × 190 × (190)²

⇒ F' = 708.53 pounds.

So, the lifting force is 708.53 pounds if the plane slows down to 190 miles per hour.

a) The equation of the profit function is \(P(x) = 37x - 1850.\)

b) The profit on 30 units is 310. This means that if the manufacturer sells 30 units, they will make a profit of 310.

c) The manufacturer must sell at least 50 fans to avoid losing money. If they sell fewer than 50 fans, they will have a negative profit, which means they will be losing money.

(a) The profit function P(x) is defined as the difference between the total revenue and the total cost, so we have:

\(P(x) = R(x) - C(x) = 80x - (43x + 1850) = 37x - 1850\)

Therefore, The profit function's equation is \(P(x) = 37x - 1850.\)

(b) To find the profit on 30 units, we substitute x = 30 into the profit function:

\(P(30) = 37(30) - 1850 = 310\)

For 30 units, the profit is 310. Accordingly, the manufacturer will make a profit of 310 if they sell 30 units.

(c) To avoid losing money, the profit must be greater than or equal to zero. Therefore, we set the profit function equal to zero and solve for x:

\(37x - 1850 = 0\\37x = 1850\\x = 50\)

To stay profitable, the company must sell at least 50 fans. They will experience a negative profit—that is, a loss—if they sell less than 50 fans.

We can infer from the data set provided that more women than men are interested in basketball.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

From table given in question

Number of males that like basketball = 21

Number of females that like basketball = 29

Percentage of males that like basketball =  (21/50)*100 = 42%

Percentage of females that like basketball =  (29/50)*100 = 58%

The answer to the nearest hundredth, the volume of the cylinder is approximately 4309.28 cubic yards.

To calculate the volume of a cylinder, we can use the formula V = πr²h, where V is the volume, r is the radius, and h is the height.

Radius (r) = 14 yards

Height (h) = 7 yards

Approximation of π = 3.14

Substituting these values into the formula, we have:

\(V = 3.14 \times(14^{2} )\times 7\)

First, let's calculate the value of (14²):

\(14^{2} = 14 \times 14 = 196\)

Now, substitute the values back into the formula:

\(V = 3.14 \times 196 \times 7\)

Next, perform the calculations:

\(V = 3.14 \times 1372\)

V ≈ 4309.28

The quotient A/B is equal to 42 + 84j, which corresponds to option b: 4 + j7.45.

To find the quotient A/B, we can perform complex division. Let's proceed with the calculation:

A/B = (68 + j16) / (2 - j4)

To simplify the expression, we can multiply the numerator and denominator by the conjugate of the denominator:

A/B = ((68 + j16) * (2 + j4)) / ((2 - j4) * (2 + j4))

Expanding the numerator and denominator:

A/B = ((68 * 2) + (68 * j4) + (j16 * 2) + (j16 * j4)) / ((2 * 2) + (2 * j4) - (j4 * 2) - (j4 * j4))

= (136 + j272 + j32 + j64) / (4 + j8 - j8 - j16)

= (136 + j272 + j32 + j64) / 4

Simplifying further:

A/B = (136 + j272 + j32 + j64) / 4

= (136 + j272 + j32 + j64) / 4

= (136 + 32) / 4 + (272 + 64) / 4j
