Consider the diagram below.
It is provided that The triangles △ WXZ and △ YZX share a side XZ.Angles ∠WXZ and ∠XZY are right angles.Angles ∠XWZ and ∠XYZ are congruent.If two angles are congruent it implies that they are same in degrees or radians.
So, the angles ∠XWZ and ∠XYZ are equal.
So, in the diagram below, one of the triangles have two angles that are equal to the corresponding angles on the other triangle and the two triangles share a side.
Then according to the Angle-Angle-Side (AAS) statement the triangles △ WXZ and △ YZX are congruent.
Thus, the correct option is AAS.

when using the method of elimination to solve the system of equations below, what is the result of adding the two equations together?
Answers
You need to manipulate the equations to get the same coefficient for one of the variables and then add or subtract the equations to eliminate that variable.
When using the method of elimination to solve the system of equations, the goal is to eliminate one of the variables by adding or subtracting the equations. To do this, you want to choose a coefficient for one of the variables that is the same in both equations, but with opposite signs.
For example, if the system of equations is:
2x + 3y = 7
4x - 5y = -13
You could multiply the first equation by -2 to get:
-4x - 6y = -14
Then, when you add this equation to the second equation, the x variable is eliminated:
-4x - 6y + 4x - 5y = -14 - 13
Simplifying this equation gives you:
-11y = -27
To find the value of y, you would divide both sides by -11:
y = 27/11
To find the value of x, you would substitute this value of y into one of the original equations and solve for x.
As for the specific question of what is the result of adding the two equations together, it depends on the coefficients of the variables in the equations. You need to manipulate the equations to get the same coefficient for one of the variables and then add or subtract the equations to eliminate that variable.

Answers
Based on the given information, it is not clear what the series "i ""c & h" or "one oh per c" refers to, and therefore it is not possible to determine which series has a greater imfs (incomplete metamorphic foliation). Further clarification or context is needed to reach a conclusion.
Without specific details or context about the series "i ""c & h" and "one oh per c," it is difficult to determine which one has a greater imfs. The concept of imfs typically pertains to geological structures and metamorphic foliation, where certain rock formations exhibit incomplete or partial foliation due to various geological processes. It is unclear how the terms "i ""c & h" and "one oh per c" relate to geological features or imfs.
To evaluate the relative imfs of the two series, one would need information about the intensity, extent, and characteristics of the metamorphic foliation observed in each series. This could include factors such as the degree of folding, preferred mineral alignment, grain size, and the presence of deformation features. Without such details, it is not possible to determine which series has a greater imfs.
To reach a conclusion, further information or clarification is needed regarding the nature of the series "i ""c & h" and "one oh per c" and how they relate to the concept of imfs.

the distribution of heights of adult men is approximately normal with mean 69 inches and standard deviation 2.5 inches. what percent of all men are -- to the nearest inch -- between 66.5 and 71.5 inches tall?
Answers
The percentage of all men between 66.5 inches and 71.5 inches is 99.99%
The mean of the heights of adult men in inches = 69
The standard deviation of the adult men in inches = 2.5
The percentage of all men between the heights of 66.5 inches and 71.5 inches can be calculated using the normal distribution.
P(66.5 < x < 71.5)
The standard form for these random samples using the formula,
Z = (X - μ) ÷ σ
where Z is the standard form
X is the random sample
μ is the mean
σ is the standard deviation.
For x = 66.5,
z = (66.5 - 69) ÷ 2.5
= -2.5 ÷ 2.5
= -1
For x = 71.5,
z = (71.5 - 69) ÷ 2.5
= 2.5 ÷ 2.5
= 1
The standardized form of those random samples are
P(66.5 < x < 71.5) = P( -1 < z < 1)
which can be written as
= P(-1 < z < 0) + P(0 < z < 1)
By using the z-table we can find the value of z
P(-1 < z < 1) = 0.15866 + 0.8413
= 0.99996
Then, the percentage of heights between 66.5 and 71.5 is
= 0.99996 x 100

If the cost of a television decreases from $1050 to $966, then by what percentage did the price of the television decrease?
Answers
Answer:
The price of the television decreased by 8%.
Step-by-step explanation:
To find the percentage decrease in the price of the television, we can use the following formula:
Percentage decrease = (original price - new price) / original price x 100%
Substituting the given values, we get:
Percentage decrease = (1050 - 966) / 1050 x 100%
= 84 / 1050 x 100%
= 0.08 x 100%
= 8%
Therefore, the price of the television decreased by 8%.

Answers
To test the hypothesis and find the upper confidence bound, we can use the R programming language. Here's the solution:
A. Hypothesis Testing:
Let's perform a hypothesis test to determine if the standard deviation of the concentration in the new process is less than 0.004 g/l.
```R
# Data
data <- c(16.628, 16.622, 16.627, 16.623, 16.618, 16.63, 16.631, 16.624, 16.622, 16.626)
# Hypothesis test
result <- t.test(data, alternative = "less", mu = 0.004)
# Output
result
```
The R output will provide the test statistic, degrees of freedom, p-value, and confidence interval. From the output, we can determine the conclusion.
B. Upper Confidence Bound:
To find the upper confidence bound for the true standard deviation, we can use the confidence interval from the previous hypothesis test.
```R
# Confidence interval
ci <- result$conf.int
# Upper confidence bound
upper_bound <- ci[2]
# Output
upper_bound
```
The R output will give us the upper confidence bound for the true standard deviation.
Now, let's interpret the results:
A. Hypothesis Testing:
Based on the R output, the p-value is greater than the significance level of 0.05. Therefore, we fail to reject the null hypothesis. There is not enough evidence to conclude that the standard deviation of the concentration in the new process is less than 0.004 g/l.
B. Upper Confidence Bound:
From the R output, the upper confidence bound for the true standard deviation is calculated. It provides an upper limit on the possible values for the true standard deviation. The specific value of the upper confidence bound depends on the data and the confidence level used.

Cones typically have pyramidal shapes with circular cross sections. A right cone is a cone with the vertex located above the base's middle. Right circular cone is another name for it. If you know the height and radius of a cone and plug those values into a formula, you can quickly determine the volume of a cone.
The volume of a cone defines the space or the capacity of the cone. A cone is a three-dimensional geometric shape having a circular base that tapers from a flat base to a point called apex or vertex. A cone is formed by a set of line segments, half-lines or lines connecting a common point, the apex, to all the points on a base that is in a plane that does not contain the apex.

Answers
The roots of the quadratic equation 0 = 2x² + 12x-14 is (C) x=-7 and x=1.
What is a quadratic equation?Any equation in algebra that can be written in the standard form where x stands for an unknown value and a, b, and c stand for known values is said to be a quadratic equation.
In general, it is assumed that a > 0; equations with a = 0 are regarded as degenerate since they become linear or even simpler.
So, the roots of 0 = 2x² + 12x-14 are:
2x² + 12x-14 = 0
2x² + 14x - 2x -14
2x(x + 7) - 2(x + 7)
(2x - 2) (x + 7)
Now, use the zero product property as follows:
2x - 2 = 0
2x = 2
x = 2/2
x = 1
And
x + 7 = 0
