The mean, summation of (x - μ), summation of (x - μ)², variance, and standard deviation will be 5, 0, 360, 72, and 8.49, respectively.

It is the measure of the dispersion of statistical data. Dispersion is the extent to which the value is in a variation. The standard deviation is given as,

[tex]\rm \sigma = \sqrt{\dfrac{\Sigma (x_i - \mu)^2}{n}}[/tex]

The data set is given below.

14, 3, -10, 12, 6

The mean of the data will be

μ = (14 + 3 - 10 + 12 + 6) / 5

μ = 25 / 5

μ = 5

The summation of the (x - μ) will be

∑(x - μ) = (14 - 5) + (3 - 5) + (- 10 - 5) + (12 - 5) + (6 - 5)

∑(x - μ) = 9 - 2 - 15 + 7 + 1

∑(x - μ) = 0

The summation of the (x - μ)² will be

∑(x - μ)² = (14 - 5)² + (3 - 5)² + (- 10 - 5)² + (12 - 5)² + (6 - 5)²

∑(x - μ)² = (9)² + (-2)² + (-15)² + (7)² + (1)²

∑(x - μ)² = 81 + 4 + 225 + 49 + 1

∑(x - μ)² = 360

Then the standard deviation (σ) will be

σ = √(360 / 5)

σ = √72

σ = 8.49

Then the variance (σ²) will be

σ² = 8.49²

σ² = 72

We need to know about unitary method to solve the given question. Option () is correct, Recycling Center A processes aluminium faster; Recycling Center B's rate is about 24 pounds per hour.

Unitary method is a method to find out the value for a single quantity and then derive the value for the asked quantity. Here is this question we know Center A processes aluminium at a rate of 100 pounds per hour and center B processes  2 tons per week, we need to know who processes aluminium faster. To find the answer we need to first find how much aluminium center B processes per hour, to find that we need to use unitary method.

1 ton=2000 pounds

so, 2tons=2x2000=4000 pounds

Thus Center B processes 4000 pounds per week

A day has 24 hours, a week has 7 days, we know that the centers operate all day every day so number of hours in a week is

7x24=168 hours

Center B processes 4000 pounds in 168 hours

Center B processes 4000/168 pounds in one hour

Center B processes about 24 pounds in one hour

Therefore, we can see that Center A processes aluminium faster and Center B's rate is about 24 pounds per hour, thus option (2) is right.

The correct way of using the equation is:

And with that we will get that the markdown is of the 5.6%

We know that the original price of the car is $27,000, and there is a markdown such that the new price of the car is $25,475.

Then, if m represents the markdown, we can write the equation:

$25,475 = (1 - m)*$27,000

Now we can solve this for m to get:

1 - $25,475/$27,000 = m = 0.056

If we want this in percentage form, we need to multiply it by 100%.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

The given system of equation is;

y = 2/3 x + 3     ----------- (1)

x= -2                 ----------- (2)

The value of x has been given in the second equation.

Now, we need to determine the value of y

From the second equation, we have that;

x = -2

Now Substitute the value of x into the first equation,

y = 2/3 x + 3

y = 2/3 (-2) + 3

y = -4/3  + 3

Step-by-step explanation:

According to the question, equation 3r + g ≤ 48 where r > 3 and g ≥ 4 represents the given situation.

When two mathematical expressions or two numbers are compared in an unequal way, it is known as an inequality in mathematics. Inequalities can generally be classified as either algebraic or numerical or as a combination of the two. When a polynomial of degree 1 is compared to another algebraic expression of a degree less than or equal to 1, this is an example of a linear inequality, which is an inequality involving at least one linear algebraic expression.

Given, A maximum of $48 can be spent during the show. Each game ticket (g) costs $1, while each ride ticket (r) costs $3. At least 4 game tickets and more than 3 transportation tickets are what you want to purchase. From that, we can drive that sum of 3 times of ride ticket and game ticket cost should be at least greater than 48. Hence,

$3 * ride cost + $1 * game cost ≤ 48

3r + g ≤ 48, where r > 3 and g ≥ 4.

The length of ribbon that remained is 3m and 90 cm which is calculated by subtracting the cut length from the total length of the ribbon.

An arithmetic operation called subtraction simulates the process of removing items from a collection.

Subtraction can mean eliminating or lowering physical and abstract quantities utilizing a variety of things, such as negative integers, fractions, irrational numbers, vectors, decimals, functions, and matrices, however it is typically linked with natural numbers in mathematics.

The total length of the ribbon is is 5 meters or 500 centimeters. The length of the piece of ribbon that was cut is 1 m 10 cm=110 cm.

Length of the ribbon that remained is calculated by subtracting the total length form the cut off length 500-110 = 390 centimeters.

The value at intercept C(1) is 95.68 pounds

The estimated per capita consumption in the year 2010 will be 115.6 pounds

Part a:

Per capita consumption of all the poultry in a country is given by the function C(x) = 2.49x + 93.19

Finding intercept C(1):

For C(1) the value of x will be 1

C(1) = 2.49(1) + 93.19

Given the dimensions of the shape, the length of PR can be found to be 19.8 units.

The given triangle is an equilateral triangle which means that all the sides are equal.

That then means that:

PR = QR

So we can solve as:

Solving for n gives:

7n - 2n = 18 + 9

5n = 27

n = 5.4

The length of PR is therefore:

The function y = 0.6 × ( 1/10)ˣ is a form of exponential decay and the value of y-intercept is 0.6.

The term "exponential decay" refers to the process of a constant percentage rate reduction in an amount over time. It can be written as y=a(1-b)ˣ, where x is the amount of time that has passed, a is the initial amount, b is the decay factor, and y is the final amount.

Consider the function,

y = 0.6 × ( 1/10)ˣ

This equation is a form of exponential decay because the number being raised in the power is a fraction, and whenever a fraction is raised to a positive power, the result decreases.

In order to determine the y-intercept of the function, we substitute the value of x as zero and find the value of y. Whenever a number is raised to zero power, the answer is always one.

Therefore,

y = 0.6 ( 1/10)ˣ

y = 0.6 × ( 1/10 )⁰

y = 0.6 × 1
