Step-by-step explanation:

Standard error with equal n = S(m1 - m2 ) = √S₁²/n₁ + S₂²/n₂

and Standard error with unequal n = S(m1 - m2 ) = √Sp²/n₁ + Sp²/n₂

What is the standard deviation?

When comparing a population mean to a sample mean, the standard error of the mean, or simply standard error, shows how dissimilar the two are likely to be. It informs you of the degree to which the sample mean would fluctuate if the research were to be repeated with fresh samples drawn from the same population.

Standard error with equal n = S(m1 - m2 ) = √S₁²/n₁ + S₂²/n₂

Standard error with unequal n = S(m1 - m2 ) = √Sp²/n₁ + Sp²/n₂

Using the standard deviation value of these interarrival times, the coefficient of variation is 0.012.

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.

The standard deviation to mean ratio, or coefficient of variation (CV), illustrates the degree of variability in proportion to the population mean. The dispersion increases with increasing CV.

Formula is given by:

\(CV = \frac {\sigma}{\mu}\)

\(\sigma = 0.02\)

Mean for the time of 0.02 sec is = 79 * 0.02

=1.58

CV= 0.02/1.58

=0.012

The practice of using brass rings to stretch the neck, also known as neck elongation or neck stretching, is traditionally associated with the Padaung ethnic group from Myanmar (formerly known as Burma).

From a sociological perspective, the use of brass rings to stretch the neck can be seen as an example of deviance, which refers to behavior that violates social norms and expectations. Deviance can be either criminal or non-criminal, depending on the specific behavior in question and the cultural context in which it occurs.

In the case of Padaung women, the use of brass rings to elongate the neck is a form of non-criminal deviance, as it does not violate any laws. However, it does violate cultural norms and expectations in many other societies, where elongated necks are not seen as desirable or attractive.

Therefore, the practice of neck elongation among Padaung women can be seen as a form of cultural deviance, in which members of a particular group engage in behavior that is not considered acceptable or desirable by the larger society in which they live. At the same time, it can also be seen as an expression of cultural identity and tradition, as the practice has been passed down through generations and is an important part of Padaung culture and heritage.

Answer:

46 degrees

Step-by-step explanation:

Angles 3 and 7 are corresponding angles which also means that they are congruent. Since they are congruent, angle 7 is also 46 degrees.

Using proportions, it is found that both patterns have the same number of ovals.

For Phil:

1 oval - 2 shapes

x oval - 96 shapes

Applying cross multiplication:

\(2x = 96\)

\(x = \frac{96}{2}\)

\(x = 48\)

For Stacy:

2 oval - 4 shapes

x oval - 96 shapes

Applying cross multiplication:

\(4x = 192\)

\(x = \frac{192}{4}\)

\(x = 48\)

Both patterns have the same number of ovals.

The temperature after 1 minute is 5, the t-coordinate of the fixed point to be equal to 1 is f(t) = 2t + 3 and the corresponding y-value is 5.

In a two-dimensional coordinate system, such as the Cartesian coordinate system, each point is represented by an ordered pair (x,y) where x represents the horizontal position and y represents the vertical position.

The problem statement asks us to find the temperature after 1 minute, which means we need to find the y-coordinate of the point on the graph that corresponds to t=1. In other words, we need to evaluate the function f at t=1 to find the corresponding y-value.

If the function f(t) is given by f(t) = 2t + 3, then the point corresponding to t=1 would have coordinates (1, 5), since f(1) = 2(1) + 3 = 5. Therefore, the corresponding y-value would be 5, which represents the temperature after 1 minute.

60 degrees, because it's an equilateral triangle, as you can tell because the sides are all the same length.

The resulting triangle is 9/5 the original triangle.

The focuses in the direction planes are A(0, 2), B(2, 1), C(- 2, - 2). In the event that the scale factor is 2, each direction point of the first triangle is duplicated by the scale factor 2. Subsequently, the expanded triangle will be A'B'C' and the direction focuses got are A'(0, 4), B'(4, 2), C'(- 4, - 4).

Let we have a triangle ABC,If this triangle undergoes a dilation with a scale factor of 9/5,

Then changed triangle is  A'B'C'

So, relation between them is A'B'C' = 9/5(ABC)

Thus, the resulting triangle is 9/5 multiple of triangle ABC.

Answer:The angle at which the first-order maximum appears can be calculated using the formula:

sin(θ) = mλ/d

where θ is the angle at which the maximum appears, m is the order of the maximum (in this case, m=1 for the first-order maximum), λ is the wavelength of the light, and d is the spacing between adjacent lines on the diffraction grating.

We can rearrange this formula to solve for d:

d = mλ/sin(θ)

For the first-order maximum:

d = (1)(λ)/(sin(12.07°))

Now, to find the angle at which the second maximum appears, we can use the same formula but with m=2:

sin(θ) = 2λ/d

Rearranging this formula to solve for θ:

θ = arcsin(2λ/d)

Substituting the values we have already calculated:

θ = arcsin(2λ/[(1)(λ)/(sin(12.07°))])

Simplifying:

θ = arcsin(2sin(12.07°))

θ ≈ 24.17°

Therefore, the second maximum will appear at an angle of approximately 24.17°.

Step-by-step explanation:

calculations:

1. We are given the number of lines per centimeter on the diffraction grating, which is 3550 lines/cm.

2.We are also given that the light forms a first-order maximum at an angle of 12.07°.

3.We can use the formula sin(θ) = mλ/d to find the spacing between adjacent lines on the diffraction grating. Rearranging this formula to solve for d, we get d = mλ/sin(θ).

4.Substituting the values m=1, λ (which we assume to be the wavelength of the light), and θ=12.07°, we can solve for d. We get d = (1)(λ)/(sin(12.07°)).

5.Next, we want to find the angle at which the second maximum appears. We can use the same formula, but with m=2: sin(θ) = 2λ/d.

6.Rearranging this formula to solve for θ, we get θ = arcsin(2λ/d).

7.Substituting the values we calculated for d and assuming the same wavelength of light, we can solve for the angle θ. We get θ = arcsin(2sin(12.07°)).

8.Finally, we evaluate this expression and get the answer: the second maximum will appear at an angle of approximately 24.17°.

To interpret this line plot with fraction addition and subtraction, we need to understand how to read the plot and how to perform the necessary calculations with fractions.

Looking at the line plot above, we can see that each horizontal line represents one pound, and each vertical line represents one baby's weight. The numbers on the vertical axis show the weights of the babies in pounds. For example, there are two babies that weigh 6 pounds, three babies that weigh 7 pounds, two babies that weigh 8 pounds, and so on. To find the difference in weight between the two heaviest babies, we need to first determine which babies are the heaviest. From the line plot, we can see that the two heaviest babies are the ones at the top of the plot, which both weigh 9 pounds. Converting the weight of the heaviest baby to a fraction with a denominator of 72 gives us 9/1 x 72/72 = 648/72. Converting the weight of the second heaviest baby to a fraction with a denominator of 72 gives us 8/1 x 72/72 = 576/72. Now that both weights are expressed as fractions with a common denominator, we can subtract them to find the difference: 648/72 - 576/72 = 72/72 = 1

Therefore, the difference in weight between the two heaviest babies is 1 pound, or 1/72 of a hundredweight (since there are 100 pounds in a hundredweight). The answer we were asked to provide is a proper fraction, so we can express this as 1/72. In summary, to interpret a line plot with fraction addition and subtraction, we need to understand how to read the plot to determine the weights of the babies, how to perform the necessary calculations with fractions, and how to express our answer as a proper fraction if required.

A linear equation is represented as

y = mx + c

Where

c = y when x = 0

This means that

c = -5

So, we have

y = mx - 5

Also, we have

(x, y) = (6, 8)
