1.386  is the sample variance .

What does the standard deviation of the sample mean?

Step 1:Add them up:

9.0 +  7.3 +  6.0 +  8.8 +  6.8 +  8.4 + 6.6  = 52.9

Step 2: Square your answer:

52.9 × 52.9 = 2798.41

…and divide by the number of items. We have 7 items in our example so:

2798.41 / 7 = 399.773

Set this number aside for a moment.

Step 3: Take your set of original numbers from Step 1, and square them individually this time:

9.0^2 +  7.3^2 +  6.0^2 +  8.8^2 +  6.8^2 +  8.4^2 + 6.6^2 = 408.09

Step 4: Subtract the amount in Step 2 from the amount in Step 3.

408.09 - 399.773 = 8.317

Set this number aside for a moment.

Step 5: Subtract 1 from the number of items in your data set. For our example:

7 – 1 = 6

Step 6: Divide the number in Step 4 by the number in.

This gives you the variance:

8.317/ 6 = 1.386

For the given rectangle, the area for given rectangle is 257 1/4 in. and length of a rectangle is 10 1/2 in. then its width is given by 24 1/2 in.

As given in the question,

For the given rectangle,

Area of a given rectangle is equal to 257 1/4 in.

length of a given rectangle is 10 1/2 in.

Let w be the width of a rectangle we have,

Area of a rectangle = length × width

257 1/4 = 10 1/2 × w

Convert mixed fraction into proper fraction we get,

(1029 /4) = (21/2) × w

⇒ w = (1029 ×2) / (21 × 4)

⇒ w = 49 /2

⇒ w = 24 1/2 in.

Therefore, for the given rectangle, the area for given rectangle is 257 1/4 in. and length of a rectangle is 10 1/2 in. then its width is given by 24 1/2 in.

The value of the sinθ is -3/5.

What is the Pythagorean identity?

The Pythagorean trigonometric identity, also known as the Pythagorean identity, is a trigonometric identity that expresses the Pythagorean theorem. It is one of the fundamental relationships between the sine and cosine functions, along with the sum-of-angles formulae.

We have,

cosθ = 4/5

sin θ = ?

We'll use the definition of cos to find the known sides of the unit circle right triangle. The quadrant determines the sign on each of the values.

[tex]cos\theta = \frac{Adjacent}{hypotenuse} = \frac{4}{5}[/tex]

We know the hypotenuse and adjacent sides and we'll use the Pythagorean theorem to find the remaining side(opposite side).

opposite = √hypotenuse² − Adjacent²

opposite = √(5)² − (4)²

opposite = √25 - 16

opposite = √9

opposite = 3

[tex]sin\theta = \frac{opposite}{hypotenuse}[/tex]

sin θ = 3/5

In the fourth quadrant, the sine and tangent ratios are negative and the cosine ratio is positive.

Hence, the value of the sinθ is -3/5.

Step-by-step explanation:

y=123.1(1.069)^x, after 1998 1 year per each.

a. solve for the number of students in 2001.

okay, so there is already the equation given, so we just have to put the right number in the x.

it says x represents the number of years after 1998;

then it means we should add the number we added in years to zero for x

(if I didn't get it wrong).

so if x is 1 in 1999, in 2001 it is 3.

let's put 3 in the equation: y=123.1(1.069)^3 -> y=123.1*1.2 -> y=147.7

answer for a: the number of students in 2001 is 147.7 in thousands.

b. solve for the number of students in 2018.

add the number you added in years to zero in order to solve x.

1998+20=2018,

0+20=20;

y=123.1(1.069)^20 -> y=123.1*3.8 -> y=467.8

answer for b: the number of students in 2018 is 467.8 in thousands.

The above equation means that

The function f(x) is the quotient of the functions g(x) and h(x)

For the function f(x) to have real values, the function h(x) must not equal 0

The vertex of your parabola lies at those two coordinates .The axis of symmetry, x is 1, was already discovered.

To locate a parabola's vertex, you must first determine x (or y, if your parabola is sideways) using the axis of symmetry formula. The quadratic equation will then be used to solve for y (or x, if your parabola opens to the side) using that value. The vertex of your parabola lies at those two coordinates.

The axis of symmetry is shown as a line, hence x=1. Since it is the highest or lowest point of the parabola, the vertex of a quadratic equation also serves as its maximum and minimum. We need to do a few things in order to locate the vertex: The axis of symmetry, x=1, was already discovered.

As per the law of sine, the value of ∠ABC is 13°

Law of sine:

In math, the law of sine refers the relationship between the sides and angles of non-right (oblique) triangles.

Given,

Triangle ABC is drawn with AB = 3.6 units. BC = 4.2 units, and BCA = 28°. Here we need to find the measure of ∠ABC.

According to the law of sine, the given measures of the given triangle  are written as,

=> sin 28°/4.2 = sin x°/3.6

Apply the value of sin 28° = 0.27, then we get,

=> 0.27/4.2 = sin x/3.6

=> 0.972/4.2 = sin x

=> sin x = 0.2314

Step-by-step explanation:

Taking into account the definition of a system of linear equations, the amount generated by person​ A's tour is ​$171 ​million, and the amount generated by person​ B's tour is ​$143 million.

A system of linear equations is a set of linear equations that have more than one unknown, related by the aforementioned equations and whose objective is to find out their values.

Then, solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied.

In this case, a system of linear equations must be proposed taking into account that:

You know:

The system of equations to be solved is

A + B= 314 million

B= A - 28 million

From the several methods to solve a system of equations, it is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.

In this case, substituting the second equation in the first one you get:

A + A - 28 million= 314 million

Solving:

A + A= 314 million + 28 million

2A= 342 million

A= 342 million÷ 2

A= 171 million

Substituting this value in the second equation:

B= A - 28 million

B= 171 million - 28 million

B= 143 million

Finally, the amount generated by person​ A's tour and B's tour is $171 million and $143 million respectively.
