A sample is a portion of a population that is used to represent the full population in statistics. Researchers frequently utilise samples to draw conclusions about the population since it might be difficult or impossible to collect data from the complete population. In order for the conclusions made from the sample to be applicable to the entire population, it is important to pick a sample that is representative of the wider population. Many techniques, such as cluster sampling, stratified sampling, and random sampling, can be used to choose samples.

The expression that is equal to 9 is 10 − (one-fifth x 10) + 1.

Basic mathematical procedures known as arithmetic are used to calculate using numbers. Addition, subtraction, multiplication, and division are the four fundamental arithmetic operations. Finding the sum of two or more numbers is done using addition, finding the difference between two numbers is done using subtraction, finding the product of two or more numbers is done using multiplication, and finding the quotient of two numbers is done using division. There are more operations outside these four, such as square root and exponentiation (increasing a number to a power) (finding the root of a number).

For the given expressions we have:

4 x (one-half x 6) ÷ 3 = 4 x 3 ÷ 3 = 4 --> not equal to 9

6 ÷ (one-fourth x 3 x one and one-fourth) = 6 ÷ (3/4 x 5/4) = 6 ÷ (15/16) = 96/15 --> not equal to 9

8 + (one-third x 6) ÷ 5 = 8 + 2 ÷ 5 = 8.4 --> not equal to 9

10 − (one-fifth x 10) + 1 = 10 - 2 + 1 = 9 --> equal to 9

Hence, the expression that is equal to 9 is 10 − (one-fifth x 10) + 1.

What is Trigonometric Functions?

Trigonometry uses six fundamental trigonometric operations. Trigonometric ratios describe these operations. The sine function, cosine function, secant function, co-secant function, tangent function, and co-tangent function are the six fundamental trigonometric functions. The ratio of sides of a right-angled triangle is the basis for trigonometric functions and identities. Using trigonometric formulas, the sine, cosine, tangent, secant, and cotangent values are calculated for the perpendicular side, hypotenuse, and base of a right triangle.

To find the height h of point P, we can use the sine function, which relates the opposite side of a right triangle (in this case, the height h) to the hypotenuse (in this case, the length of the windmill blade, which is 1.5 feet). The angle between the opposite side and the hypotenuse is the complement of the angle of rotation a, which is π/4 radians minus the angle between the ground and the windmill blade, which is arctan(6/1.5) or approximately 1.3258 radians.

So, the equation for the height h of point P after the windmill blade rotates by an angle of a is: h = 1.5 sin(π/4 - arctan(6/1.5))

Therefore, the height of point P after the windmill blade rotates by an angle of a is approximately 1.1908 feet.

According to the solution we have come to find that, The possible coordinates of point A are (2,-2) and (2,4).

Geometry is a branch of mathematics that deals with the study of spatial relationships and properties of objects. It is concerned with the study of shape, size, position, and relative orientation of objects, as well as their properties such as angles, lines, curves, surfaces, and solids. Geometry is used extensively in various fields, including architecture, engineering, physics, astronomy, and computer graphics. The study of geometry involves using logic and reasoning to analyze and solve problems related to shapes and spatial relationships. It is an important subject that has practical applications in many areas of everyday life.

To find the possible coordinates of point A, we need to use the distance formula and the fact that the x-coordinate of point A is 2.

The distance formula is:

d = √((x2 - x1)² + (y2 - y1)²)

where (x1, y1) are the coordinates of point A, (x2, y2) are the coordinates of point B, and d is the distance between the two points.

We know that the distance between point A and point B is 5 units:

5 = √((5 - 2)² + (1 - y1)²)

Squaring both sides:

25 = (5 - 2)²+ (1 - y1)²

Simplifying:

9 = (1 - y1)²

Taking the square root of both sides:

3 = 1 - y1 or 3 = y1 - 1

Solving for y1 in each case:

y1 = -2 or y1 = 4

Therefore, the possible coordinates of point A are (2,-2) and (2,4).

Below are the three angles listed out in both radians and degrees:

Let us assume that point P is initially at the topmost point of the wheel, and Q is directly to the right of P.

When the wheel rotates counterclockwise, point P moves along a circle with radius 1 foot, centered at the center of the wheel. To end up at position Q, point P needs to move a quarter of the way around the circle, or pi/2 radians. Therefore, one angle that the wheel can rotate is pi/2 radians (or 90 degrees).

Another angle that the wheel can rotate is 5*pi/2 radians (or 450 degrees), which corresponds to rotating the wheel counterclockwise almost all the way around the circle, but stopping just short of completing a full rotation.

A third angle that the wheel can rotate is 9*pi/2 radians (or 810 degrees), which corresponds to rotating the wheel counterclockwise almost twice around the circle, but stopping just short of completing two full rotations.

Therefore, Note that there are a lot of many other angles that the wheel can rotate to end up at position Q, but these three examples give an idea of the possibilities.

Answer:

$1529

Step-by-step explanation:

The formula for continuous compounding is:

A = Pe^(rt)

Where:

A = the final amount (balance) in the account

P = the initial principal (deposit)

e = Euler's number (approximately 2.71828)

r = the annual interest rate (as a decimal)

t = the time period (in years)

Plugging in the given values, we get:

A = 1000e^(0.0855)

A = 1000*e^0.425

A = 1000*1.529

A = 1529

Therefore, the balance after 5 years with continuous compounding at 8.5% interest rate is $1529.

Answer:

1/72

Step-by-step explanation:

There are a total of 17 students in the class, and we want to choose one boy from 9 and one girl from 8 without replacement. The total number of ways to choose two students from the class is:

17C2 = (17!)/(2!15!) = (1716)/(21) = 136

To choose a boy and a girl, we can choose the boy in 9 ways and the girl in 8 ways, for a total of 9*8 = 72 ways.

Now, since the brother and sister are both in the class, there is only one way to choose them together. Therefore, the probability of choosing the brother and sister is:

1/72

So the probability is 1/72, written as a fraction in simplest form.

well, the amount off from the original 125 is just 125 - 87.50 = 37.50.

now, if we take 125(origin amount) as the 100%, what's 37.50 off of it as a percentage?

[tex]\begin{array}{ccll} Amount&\%\\ \cline{1-2} 125 & 100\\ 37.50& x \end{array} \implies \cfrac{125}{37.50}~~=~~\cfrac{100}{x} \\\\\\ 125x=3750\implies x=\cfrac{3750}{125}\implies x=30[/tex]

To determine what percent off the sale for something was, we need to use the formula for percent off calculation.

What is percent off? The percent off is used to refer to the reduction in price or value of something. The percent off calculation is used to determine the amount of discount in percentage of the original price or value.

What is the formula for percent off calculation? The formula for percent off calculation is as follows:

percent off = (discount / original price) x 100, where,discount = original price - sale price

original price = $125 sale price = $87.50

Substitute the given values into the formula and simplify.

percent off = (discount / original price) x 100percent off =

(($125 - $87.50) / $125) x 100percent off

(37.50 / 125) x 100percent off

⇒ 0.3 x 100percent off = 30%

Therefore, the percent off the sale was 30%.

The term proportionality describes any relationship that is always in the same ratio. The number of apples in a crop, for example, is proportional to the number of trees in the orchard, the ratio of proportionality being the average number of apples per tree.

Given that

the pressure varies directly with the depth. When the pressure is 320 g/m² the depth is 480 m.

We need to find the depth if the pressure is 2.6 g/m².

So, here we will use the concept of proportionality,

Let the unknown depth be x,

So,

320 / 480 = 2.6 / x

Answer:

the length of the rectangle is 21 feet.

Step-by-step explanation:

Let's use "w" to represent the width of the rectangle. According to the problem, the length is three times the width, so we can use "3w" to represent the length.

The perimeter of a rectangle is given by the formula:

Perimeter = 2(length + width)

Substituting the expressions for length and width, we get:

56 = 2(3w + w)

Simplifying the right side, we get:

56 = 2(4w)

56 = 8w

w = 7

So the width of the rectangle is 7 feet. To find the length, we can use the expression we derived earlier:

length = 3w = 3(7) = 21

Therefore, the length of the rectangle is 21 feet.

As per the mentioned informations and values provided, the mean from this sample frequency distribution is calculated to be approximately 160.50.

To find the mean from the given sample frequency distribution, we need to first calculate the midpoint for each class interval, then multiply it by the corresponding frequency, sum all of these products, and finally divide by the total frequency.

Using the formula: mean = (sum of midpoint x frequency) / (sum of frequency)

Midpoint for the first interval = (0 + 70) / 2 = 35

Midpoint for the second interval = (70 + 200) / 2 = 135

Midpoint for the third interval = (200 + 500) / 2 = 350

Now we can calculate the sum of midpoint x frequency:

35 x 73 + 135 x 37 + 350 x 182 + 232 x 500 = 84,166

The total frequency is the sum of all frequencies: 73 + 37 + 182 + 232 = 524

Finally, we can calculate the mean:

mean = (sum of midpoint x frequency) / (sum of frequency) = 84,166 / 524 ≈ 160.50

Therefore, the mean from this sample frequency distribution is approximately 160.50.

The solution for x is -21 when rectangle JKLM below, JN = 44.

If MN = -2x + 2,

What is the rectangle?

A rectangle is a geometric shape with four sides and four right angles. It is a quadrilateral in which opposite sides are equal in length and parallel to each other, and adjacent sides are perpendicular to each other.

To solve for x, we can use the given information that JN = 44 and MN = -2x + 2 in the rectangle JKLM.

Since JN is a side of the rectangle and is equal to 44, and MN is also a side of the rectangle and is equal to -2x + 2, we can set up the equation:

JN = MN

44 = -2x + 2

Now we can solve for x:

Add 2x to both sides:

44 + 2x = 2

Subtract 2 from both sides:

44 + 2x - 2 = 0

42 + 2x = 0

Subtract 42 from both sides:

42 + 2x - 42 = 0 - 42

2x = -42

Finally, divide both sides by 2 to isolate x:

2x / 2 = -42 / 2

x = -21

The equation of the line of reflection is y = (−13 / 45)x − (1376 / 45) in point-slope form.

To find the equation of the line of reflection between the points (-9, 12) and (17, -78), we first need to find the midpoint of the line segment joining these two points, which will lie on the line of reflection. The midpoint formula is:

[(x₁ + x₂) / 2, (y₁ + y₂) / 2]

Using the coordinates of the two given points, we get:

[(−9 + 17) / 2, (12 − 78) / 2] = [4, −33]

So, the midpoint is (4, −33).

Next, we need to find the slope of the line of reflection. This is equal to the negative reciprocal of the slope of the line passing through the two given points, since the line of reflection is perpendicular to this line. The slope of the line passing through the two given points is

m = (y₂ − y₁) / (x₂ − x₁) = (−78 − 12) / (17 − (−9)) = −90 / 26 = −45 / 13

So, the slope of the line of reflection is:

m' = −1 / m = −13 / 45

Finally, we can use the point-slope form of the equation of a line, with the midpoint we found as the point and the slope we calculated as the slope which is

y − (−33) = (−13 / 45)(x − 4)

y + 33 = (−13 / 45)x + (52 / 45)
