The relationship between AABC and ARST is that they are always is neither congruent nor similar. 4.

The relationship between AABC and ARST, after the described transformations (translation and line reflection), can be determined based on the properties of the transformations.

Congruent and Similar:

Congruent figures have the same shape and size, while similar figures have the same shape but different sizes.

Since the question mentions a translation and a line reflection, these transformations preserve both shape and size.

If AABC and AJED are congruent due to the translation and AJED and ARST are also congruent due to the line reflection, then AABC and ARST would be congruent as well.

However, the question does not specify whether the figures are similar or not, so we cannot conclude that they are similar.

Congruent but Not Similar:

As mentioned earlier, congruent figures have the same shape and size.

If AABC and AJED are congruent due to the translation and AJED and ARST are congruent due to the line reflection, it follows that AABC and ARST would also be congruent.

We cannot determine whether they are similar or not.

Similar but Not Congruent:

Similar figures have the same shape but different sizes.

Since the question does not provide any information about the angles or side ratios of the figures, we cannot conclude that AABC and ARST are similar.

Neither Congruent nor Similar:

Based on the information given, this is the most accurate choice.

Without additional information about the angles or side ratios, we cannot determine whether AABC and ARST are congruent or similar.

Answer:

25 x 0.84 ^ h = X

After 4 hours there will be 12.45 milligrams of the medicine, and after 8 hours there will be 6.20 milligrams of it.

Step-by-step explanation:

Given that a particular medicine decays at a rate of 16% every 4 hours, if a person takes a 25 mg dose, to write a function that represents the amount of medicine after h hours, and determine how much is left after 4 hours and 8 hours, the following calculations must be performed:

100 - 16 = 84

25 x 0.84 ^ h = X

25 x 0.84 ^ 4 = X

25 x 0.4978 = X

12.45 = X

25 x 0.84 ^ 8 = X

25 x 0.2478 = X

6.20 = X

Therefore, after 4 hours there will be 12.45 milligrams of the medicine, and after 8 hours there will be 6.20 milligrams of it.

The angles and length of the right triangle are as follows:

WX = 10√141 units

m∠X  = 30°

m∠V = 60°

A right angle triangle is a triangle that has one of its angles as 90 degrees. The sum of angles in a right angle triangle is 180 degrees.

Trigonometric ratios can be used to find the side and angles of the right triangle as follows;

Therefore,

Using Pythagoras's theorem,

WX² = (20√47)² - (10√47)²

WX² = 400(47) - 100(47)

WX² = 18800 - 4700

WX = √14100

WX = 10√141

Let's find the angles

sin m∠X  = opposite / hypotenuse

sin m∠X  = 10√47 / 20√47

sin m∠X  = 1 / 2

m∠X  = sin⁻¹ 0.5

m∠X  = 30 degrees

Therefore,

m∠V = 180 - 90 - 30

m∠V = 60 degrees

The stream velocity has no influence on the amount of dissolved load it contains. The amount of dissolved material depends on erosion and deposition carried out in the watercourse. These are affected by factors such as the slope of the land, the resistance of the material to erosion, the size of the sediments transported, etc.

Stream velocity plays an important role in the transport of sediments and dissolved loads in a watercourse. It affects the erosion and deposition processes that occur in the watercourse, which in turn affect the amount of sediment and dissolved load that is carried by the stream. For example, faster stream velocities can cause more erosion of the stream bed, leading to more material being carried in the water.

Sediment is any particulate matter that is transported by a fluid, and it can come in many different forms. The three main types of sediment are:

The exact values of the sine, cosine, and tangent of the angle 255° are -1/√2, 1/√2, and -1, respectively.

To find the exact values of the sine, cosine, and tangent of the angle 255°, we can use the identity that relates the trigonometric functions of an angle to the trigonometric functions of its complement.

By expressing 255° as the sum of 300° and -45°, we can determine the exact values of the trigonometric functions for the given angle.

We know that the sine, cosine, and tangent of an angle are periodic functions, repeating every 360 degrees. To find the exact values of the trigonometric functions for 255°, we can express it as the sum of 300° and -45°, where 300° is a multiple of 360°.

Since the sine, cosine, and tangent functions are odd or even functions, we can use the values of the trigonometric functions for 45° to determine the values for -45°.

For 45°:

sin(45°) = cos(45°) = 1/√2

tan(45°) = 1

Since cosine is an even function, cos(-45°) = cos(45°) = 1/√2.

Since sine is an odd function, sin(-45°) = -sin(45°) = -1/√2.

Using the definition of tangent as the ratio of sine to cosine, tan(-45°) = sin(-45°) / cos(-45°) = (-1/√2) / (1/√2) = -1.

Therefore, for the angle 255°:

sin(255°) = -1/√2

cos(255°) = 1/√2

tan(255°) = -1

The conditional probability mass function P(X=k∣X+Y=m)= P(X=k, Y=m-k) / P(X+Y=m)

To find the conditional probability mass function P(X=k∣X+Y=m) for independent Poisson random variables X and Y, follow these steps:

1. Write down the joint probability mass function of X and Y:

P(X=k, Y=n)

= P(X=k) * P(Y=n)  since X and Y are independent.
2. Express P(X=k) and P(Y=n) using the Poisson probability mass function:

P(X=k) = (e^(-λx) * λx^k) / k! and P(Y=n) = (e^(-λy) * λy^n) / n!

3. Plug these expressions into the joint probability mass function:

P(X=k, Y=n)

= [(e^(-λx) * λx^k) / k!] * [(e^(-λy) * λy^n) / n!]

4. Write down the marginal probability mass function for

X+Y: P(X+Y=m)

= Σ [P(X=k, Y=m-k)]   for k=0 to m, where the summation is over all possible values of k.

5. Calculate the conditional probability mass function P(X=k∣X+Y=m) by dividing the joint probability mass function by the marginal probability mass function:

P(X=k∣X+Y=m) = P(X=k, Y=m-k) / P(X+Y=m)

In summary, the conditional probability mass function P(X=k∣X+Y=m) for independent Poisson random variables X and Y can be found using the joint probability mass function, the Poisson probability mass function, and the marginal probability mass function.

The regression analysis yielded a fitted line, y = 35 - 1.2x, with a coefficient of determination of 0.7632, a correlation coefficient of 0.8740, and a predicted mean of Y = 23 when X = 10.

To compute the coefficient of determination (r²), the correlation coefficient (r), and the predicted mean of Y when X = 10, we can use the given regression line y = 35 - 1.2x and the formulas related to regression analysis.

The coefficient of determination (r²) represents the proportion of the total variation in the dependent variable (Y) that can be explained by the independent variable (X). It is calculated by dividing the explained sum of squares (SSR) by the total sum of squares (SSY).

[a] To compute r²:

SSR = SSY - SSE

SSR = 2758 - 652 = 2106

r² = SSR / SSY

r² = 2106 / 2758 = 0.7632

Therefore, the coefficient of determination (r²) is 0.7632 (rounded to four decimal places).

[b] To compute the correlation coefficient (r):

We can use the formula:

r = √(r²)

r = √(0.7632) = 0.8740

Therefore, the correlation coefficient (r) is 0.8740 (rounded to four decimal places).

[c] To compute the predicted mean of Y when X = 10:

We can substitute the value of X = 10 into the regression line equation y = 35 - 1.2x:

y = 35 - 1.2(10)

y = 35 - 12

y = 23

Therefore, the predicted mean of Y when X = 10 is 23.

The inequality that represents the graph in the given diagram is: y ≥ 4x - 6.

The inequality sign to use depends on the boundary line, whether it is dashed or solid line. And also, it depends on where the shaded area of the graph lies, above or below the boundary line.

The boundary line in the graph is a solid line, and the shaded area is above the boundary line, therefore, the inequality sign we would use is, "≥".

Find the slope (m) of the boundary line.

Slope (m) = rise/run = 4 units / 1 unit

Slope (m) = 4

The y-intercept (b) is -6 [this is where the value of x = 0, and also the point where the y-axis is intercepted].

Substitute m = 4 and b = -6 into y ≥ mx + b

Therefore, let's find the angle of x using the angle relationships as follows:

The size of the angle x can be found as follows:

82 + x = 180(same side interior angles)

Same side interior angles are supplementary.

Answer:

y = 4x - 4

Step-by-step explanation:

to write a linear equation you need to know 2 components:  slope and y-intercept

find slope by selecting 2 points, for example, (1,0) and (2,4)

slope ('m') = difference of y-values              4 - 0  =  4

                    difference of x-values             2 - 1        1

to find y-intercept ('b'), plug values into the slope-intercept form of a line, which is:

y = mx + b

you need a point and the slope of 4/1; can use any point

we'll use (2,4) where x =2 and y=4  and, again, m = 4

4 = 2(4) + b

4 = 8 + b
