Standard deviation does not mean independent events.

No, the standard deviation is a measure of the spread or variability of a set of data. It measures how much the individual data points in a dataset deviate from the mean or average of the dataset.

Independence, on the other hand, refers to the relationship between two or more events, where the occurrence of one event does not affect the probability of the other event occurring.

Standard deviation is not directly related to the concept of independence. However, when calculating the standard deviation of a dataset, it assumes that each data point is independent and identically distributed. This means that the value of one data point does not affect the value of another data point, and that each data point is drawn from the same underlying distribution.

To compute the selling price per unit using the total cost method, we need to add the markup to the total costs.

To compute the target cost per unit, we need to subtract the target profit from the expected selling price. The target profit is 60% of the expected selling price, which is equal to 0.6 * $800 = $480. The target cost per unit is the expected selling price minus the target profit, which is

$800 - $480 = $320.

To compute the selling price per unit using the variable cost method, we need to add the markup to the variable costs. The variable costs for one unit is the sum of the variable overhead and variable selling, general, and administrative costs, which is $22 + $18 = $40. The markup is 200% of variable costs, which is equal to 2 * $40 = $80. The selling price per unit is the sum of variable costs and the markup, which is $40 + $80 = $120.

The illustration below is a semi-regular tessellation is a false statement.

Tessellation is defined as the process of covering of a surface or a plane using the geometric shapes.

One geometric shape will not overlap with the other and there will not be any gaps in between.

There are regular tessellations as well as semi-regular tessellations.

Regular tessellations are the tessellations which are made using only a single type of the polygon to cover the entire surface.

Whereas in semi-regular tessellations, two or more regular polygons are used such that each vertex is the same to cover the surface.

Here, the illustration contains only one type of polygon which are tiled to each other with out any gaps.

It is actually regular tessellation.

Hence the statement that the illustration is semi-regular tessellation is incorrect.

Answer:

c

Step-by-step explanation:

Let us go through each of the choices one by one.

(a).

A rotation 90 degree clockwise followed by a translation 3 units down.

This Lands the L'M'N' into the first quadrant and L'N' is now parallel to the y-axis; therefore, this transformation leaves the corresponding sides not being parallel to the same axis and hence is the correct option to choose.

(b).

A translation 4 units to the left followed by a reflection over the y-axis.

A translation of 4 units to the left leaves the sides parallel and the reflection over the y-axis also leaves the sides parallel; therefore, this is not the correct option to choose.

(c).

A reflection over the x-axis followed by a dilation by a factor of 2 about the origin.

The reflection over the x-axis leaves the sides parallel and dilation by a factor of 2 just bloats the figure - it does not change the angle of sides with respect to the x and y axes; therefore, this choice is also not the correct one to choose.

(d).

A dilation by a factor of 0.25 about the origin followed by a 180° rotation clockwise about the origin.

The dilation by a factor of 0.25 shrinks the triangle, and the 180° rotation clockwise leaves the side L'M' parallel to the x-axis - the same as it was before; therefore, this is not the correct choice to choose.

Hence, the correct option is A.

Answer:

its 5 hours i think

Step-by-step explanation:

Despite traditional economic theory suggesting that an increase in the minimum wage should lead to unemployment, the actual impact on employment has been more nuanced. Empirical evidence suggests that moderate increases in the minimum wage have not led to massive job losses, but rather have resulted in small increases in labor costs that are offset by increased productivity and reduced employee turnover. Additionally, higher wages can increase consumer spending, leading to an increase in demand for goods and services, which can ultimately create more jobs.

There are several reasons why the federal minimum wage in the US is lower than in other developed countries. One reason is the political climate in the US, where there is often resistance to government intervention in the labor market. Additionally, many US states have their own minimum wage laws, which can be higher than the federal minimum wage. Finally, the US has a large low-skilled immigrant workforce, which can put downward pressure on wages.

I am not okay with the real minimum wage falling over time with the rise of inflation. Inflation erodes the purchasing power of workers, making it difficult for them to make ends meet. This can lead to increased financial hardship, which can have negative effects on individuals and families. Furthermore, the minimum wage was originally designed to ensure that workers earn a living wage, which is a basic necessity for a decent standard of living. As such, it is important that the minimum wage keep pace with inflation.

According to the Bureau of Labor Statistics, in 2021, about 1.9 million workers in the US earned at or below the federal minimum wage of $7.25 per hour. However, many more workers earn slightly above the minimum wage, and an increase in the minimum wage could potentially raise wages for those workers as well. Additionally, many states have higher minimum wage rates than the federal minimum wage, which means that the number of workers affected by changes to the minimum wage will vary depending on the state.

Answer:

(x + i) (x - i)

Step-by-step explanation:

The expression x^2 + 1 is a sum of squares, which means that it cannot be factored using real numbers. However, it can be factored using complex numbers.

To factor x^2 + 1, we can use the fact that i^2 = -1, where i is the imaginary unit.

We can rewrite x^2 + 1 as:

x^2 + 1 = x^2 - (-1)

Now, we can use the difference of squares formula to factor x^2 - (-1):

x^2 - (-1) = (x + i)(x - i)

Therefore, the factored form of x^2 + 1 is:

(x + i)(x - i)

\( \huge \bf \: Question : \)

\(3 = 2x\)

This is an equation. We need to find the value of X and verify it.

\( \huge \bf \: Solution : \)

Let's find out the value of X :-

\( \sf \implies \: 3 = 2x\)

Firstly, over turn the equation :-

\(\sf \implies2x = 3\)

Then, Divide both sides of this equation by 2 :-

\(\sf \implies \: \dfrac{2x}{2} = \dfrac{3}{2} \)

Cancel 2/2 on this equation and Leave x :-

3/2 can't be cancelled.

\(\sf \implies \: \dfrac{ \cancel2x}{ \cancel2} = \dfrac{3}{2} \)

\(\sf \implies \: x = \dfrac{3}{2} \)

Hence the value of x is 3/2.

________________________________

\( \bf \huge \: Verification : \)

Put the value of x on this equation :-

\(\sf \implies \: 3 = 2x\)

On Putting 3/2 instead of x :-

As we know that x is multiplied with 2 so,

\(\sf \implies \: 3 = 2 \times \dfrac{3}{2} \)

Simplify this equation(Cancel 2 and 2) :-

\(\sf \implies \: 3 = \cancel2 \times \dfrac{3}{ \cancel2} \)

\(\sf \implies \: 3 = 3\)

\(\sf \implies \bf \: L HS = RHS\)

\( \boxed {\bf\huge Hence, verified.}\)
