The value of x in 1 1/8=2 1/4x by using inverse operation is 1 / 2.

Addition and subtraction, multiplication, and division are examples of inverse operations, which are pairs of mathematical operations where one operation reverses the effects of the other.

Given:

1 1/8=2 1/4x

Solve the above equation by using the inverse operation.

Solve the mixed fraction into improper fractions as shown below,

9 / 8 = 9 / 4 x

x = 9 / 8 × 4 / 9

The solution is Square ABCD is reflected about the side BC

Option A.

Option C.

Option D.

What is Reflection?

Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point. The line of reflection is the line that a figure is reflected over. If a point is on the line of reflection then the image is the same as the pre-image. Images are always congruent to pre-images.

The reflection of point (x, y) across the x-axis is (x, -y). When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

Given data ,

Let the figure be a square

Now , the sides of the square ABCD is AB , BC , CD and DC

The square ABCD is reflected about the side BC

So , the possible relations are

The reflected square will be A'B'C'D'

where length of side AB = A'B'

length of side BC = B'C'

length of side CD = C'D'

length of side DA = D'A'

So ,

The vertex B is the midpoint of side AA'

And the vertex C = C'

And , the length of the side CD = C'D'

Hence , The vertex B is the midpoint of side AA'

And the vertex C = C'

And , the length of the side CD = C'D'

3 is the standard deviation of the  population.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

The given data is {5, 8, 8, 5}

We need to find the standard deviation.

Before finding standard deviation we need to find the mean and then variance.

The mean of the population = Sum of the terms /  Number of Terms

=5+8+8+5/4

=26/4

=6.5

The variance of the population = (5 - 6.5)² + (8 - 6.5)² + (8 - 6.5)² + (5 - 6.5)²

= (-1.5)² + (1.5)² + 1.5² + (-1.5)²

= 2.25 + 2.25 + 2.25 + 2.25

= 9

Standard deviation is square root of variance

Standard deviation=√variance

=√9

The required probability for P(all numbers are chosen), P(none of them are chosen), P (precisely four are chosen) are 0.24094, 0.75906,  0.1473 respectively.

A probability is a number that mirrors the opportunity or probability that a specific occasion will happen. Probabilities can be communicated as extents that reach from 0 to 1, and they can likewise be communicated as rates going from 0% to 100 percent.

The complete likelihood of picking any 20 arbitrary balls out of 80 is ⁸⁰C₂₀ . We use mix since the request for determination doesn't make any difference

a) P(all numbers are chosen)

¹⁰C₁₀ are our numbers,⁷⁰C₁₀ is the choice of other ten numbers separated from our numbers.

So, ¹⁰C₁₀×⁷⁰C₁₀ /⁸⁰C₂₀ = 0.24094

b) P(none of them are chosen)

Since our numbers are not really chosen, we accept that every one of the numbers chose are from the other 70.

So, 1 - 0.24094 = 0.75906

c) P (precisely four are chosen)

Just four from our numbers are chosen and the rest 16 from the other 70 numbers.

Then, ¹⁰C₄×⁷⁰C₁₆ /⁸⁰C₂₀ = 0.1473

Thus, required probabilities are 0.24094, 0.75906,  0.1473 respectively.

The population means may be the same

So, option D is correct.

In statistics, the probability that a population parameter will fall between a set of values a predefined percentage of the time is known as the confidence interval. Analysts typically use confidence intervals that cover 95% or 99% of the expected observations while assessing data. In frequentist statistics, an estimation range for an unknown parameter is referred to as a confidence interval. The most common confidence level for computing confidence intervals is 95%, however other levels, such 90% or 99%, are also occasionally employed. The conclusion is reached that the result is statistically significant if the confidence interval eliminates the value of zero effect.

If (μ₁- μ₂=0) is included in the confidence interval, that means this two means have the same difference that is zero.

Therefore, they may be nearly same,

The equation of the straight line would be y = (-5/2) + 15.5.

The general equation of a straight line is -

Other possible equations of lines are -

We have a triangle ABC is defined by the points A(3, 8), B (7, 5), and C(2, 3).

Assume the equation of the line to be -

y = mx + c

The slope of line BC will be -

m{BC} = (3 - 5)/(2 - 7)

m{BC} = - 2/- 5

m{BC} = 2/5

So -

m{BC} x m{l} = - 1

m{l} = -1/(2/5)

m{l} = -5/2

The equation will be -

y = (-5/2)x + c

For the point A(3, 8) -

y = (-5/2)x + c

8 = (-5/2) x 3 + c

8 = -7.5 + c

c = 8 + 7.5

c = 15.5

The statement that is true about the given equation is that it has no solution. This can be seen by rearranging the terms on both sides of the equation and then solving for y. When we do this, we get:

3(-y + 7) = 3(y + 5) + 6

-3y + 21 = 3y + 15 + 6

-6y = -12

y = 2

However, when we substitute this value of y back into the original equation, we find that it does not satisfy the equation. This means that there is no value of y that can make the equation true, so the equation has no solution.

The height and radius of the cup that will use the smallest amount of paper are 3.86 cm and 2.72 cm. The result is obtained by using the first derivative .

To find the height and radius of a cone for the smallest surface area, we can use the first derivative dS/dh. We then equate it to 0 for the maximum value.

The volume of a cone-shaped paper drinking cup is 30 cm³. Find the height and radius for the smallest amount of paper!

The radius of the cone can be expressed as

V = 1/3 (πr²h)

30 = 1/3 (πr²h)

90 = πr²h

r² = 90/πh

The surface area of the cone can be expressed as

S = πrs

[tex]S = \pi r \times \sqrt{h^{2} + r^{2}}[/tex]

[tex]S = \pi \sqrt{\frac{90}{\pi h}} \times \sqrt{{h^{2} + \frac{90}{\pi h}[/tex]

[tex]S = \pi \sqrt{\frac{90}{\pi h}} \times \sqrt{\frac{(\pi h^{3} + 90)}{\pi h}[/tex]

[tex]S = \sqrt{90} \times \sqrt{\frac{(\pi h^{3} + 90)}{h^{2}}[/tex]

[tex]S = \sqrt{90} \times \sqrt{\pi h + \frac{90}{h^{2}} }[/tex]

The 1st derivative is

[tex]\frac{dS}{dh} = \sqrt{90} \times (\pi - \frac{180}{h^{3}}) \times [(\pi h + \frac{90}{h^{2}})^{-\frac{1}{2} } ][/tex]

[tex]0 = \sqrt{90} \times (\pi - \frac{180}{h^{3}}) \times [(\pi h + \frac{90}{h^{2}})^{-\frac{1}{2} } ][/tex]

The height for the smallest amount of paper is

π - 180/h³ = 0

π = 180/h³

h³ = 180/π

h³ = 57.32

h = 3.86 cm

The radius for the smallest amount of paper is

r² = 90/πh
