Yes AAS and SAA are the same Methods for determining whether two triangles are congruent.

The acronym AAS or SAA stands for "Angle, Angle, Side or Side, Angle, Angle" denoting two angles and a side opposite them. AAS os SAA is one of the five methods for determining whether two triangles are congruent. It states that two triangles are congruent if their vertices are in one-to-one correspondence, that is if two angles and the side that is opposite to one of them in one triangle are congruent to the corresponding angles and the side that is not included in the second triangle. The side that is in opposition to either of the angles that are being used is called the non-include side. In layman's terms, two triangles are congruent if the sides of two pairs of corresponding angles are equal in each triangle.

The statement is true that is root 2 over 2 is equal to 1 over root 2 is true we can write as √2/2=1/√2.

Given that,

We have to find is root 2 over 2 is equal to 1 over root 2.

We know that,

A number can be squared, but it can also be divided into its square root. The value we get from multiplying a number by itself yields its square value, whereas the value we get from finding a number that, when squared, yields the original value of the number yields its square root value.

Now,

Root 2 over 2 is equal to 1 over root 2 can write as

√2/2=1/√2

Taking multiplying √2 on both side.

√2/2×√2=1/√2×√2

(√2×√2)/2=(1×√2)/√2

2/2=√2/√2

1=1

Therefore, The statement is true that is root 2 over 2 is equal to 1 over root 2 is true we can write as √2/2=1/√2.

Motion that keeps a distance while traveling in a plane is referred to as rigid body motion. There are four types of transformations, also called stiff, congruent, isometric, or similar terms.

The separation between each pair of the geometric object's points is preserved during a rigorous change of the object. In other words, a rigid transformation maintains the object's size and shape. For instance, the rigid transformation of a triangle retains the angles and lengths of the triangle. Imagine a stiff shape distortion, similar to a cardboard shape. The form remains the same after being pushed left and right, rotated, and flipped. When the mold was created using putty, the opposite was true. The thing can then be twisted and stretched. These conversions, nevertheless, are not exact. Stretching a form alters the distances between each pair of its points.

Answer:

To find the quotient of 3/4 and 5/6, divide each number by 2: 3/4 = 1/2 and 5/6 = 3/4. Therefore, the quotient is 1 1/9.

Step-by-step explanation:

With a 95 percent confidence interval, you have a 5 percent chance of being wrong.

You have a 5% probability of being incorrect with a 95% confidence interval. You have a 10% probability of being incorrect with a 90% confidence interval. A 95% confidence interval is narrower than a 99% confidence interval (for example, plus or minus 4.5 percent instead of 3.5 percent).

What is the correct calculation for a 95% confidence interval?

The 68-95-99.7 Rule states that 95% of values lie within two standard deviations of the mean, hence to get the 95% confidence interval, you add and subtract two standard deviations from the mean.

In statistics, confidence is another word for probability. If you create a confidence interval, for instance, with a 95% level of confidence, you can be sure that 95 out of 100 times, the estimate will fall between the upper and lower values indicated by the confidence interval.

Step-by-step explanation:

The expected value to pick a package is $.1125.

To find the expected value, you need to multiply the value of each package by the probability of selecting it and then add up all of these values.

The probability of selecting one of the $.70 packages is 20/40 = 1/2, since there are a total of 40 packages and 20 of them are worth $.70. The expected value of selecting one of these packages is $.70 * (1/2) = $.35

The probability of selecting one of the $.60 packages is 15/40 = 3/8, since there are a total of 40 packages and 15 of them are worth $.60. The expected value of selecting one of these packages is $.60 * (3/8) = $.22.5

The probability of selecting one of the $.30 packages is 5/40 = 1/8, since there are a total of 40 packages and 5 of them are worth $.30. The expected value of selecting one of these packages is $.30 * (1/8) = $.0375

The expected value of selecting one package at random is therefore $.35 + $.22.5 + $.0375 = $.61.25. However, you have to pay $.50 to pick a package, so the net expected value is $.61.25 - $.50 = $.1125.

Picking a bundle is anticipated to be worth $.1125.

You must multiply the value of each package by the likelihood that it will be chosen before adding up all of these values to arrive at the expected value.

Given that there are a total of 40 packages and 20 of them are valued at $.70 each, the likelihood of choosing one of the $.70 packages is 20/40 = 1/2. Selecting one of these packages has an expected value of $.70 * (1/2) = $.35.

Given that there are 40 products in total and 15 of them are worth $.60 each, the probability of choosing one of the $.60 packages is 15/40 = 3/8. Choosing one of these packages will result in a value of $.60 * (3/8) = $.22.5.

There are a total of 40 packets, and 5 of them are worth $.30, hence the likelihood of choosing one of the $.30 packages is 5/40 = 1/8. By choosing one of these packages, the predicted value is $.30 * (1/8) = $.0375.

Therefore, $.35 + $.22.5 + $.0375 = $.61.25 is the expected value of choosing one package at random. The net expected value is $.61.25 - $.50 = $.1125 due to the fact that you must pay $.50 to choose a bundle.

The equation for graphing y = 4 in slope-intercept form is y = 4x + 0. This equation can be graphed by plotting the point (0, 4) and then using the slope of 0 to draw a horizontal line that passes through that point.

The formula for finding the asymptote of a hyperbola is

y-k =+/- b/a( x-h)

Hyperbola

A hyperbola is an open curve with two branches, the intersection of a plane with both halves of a double cone. The plane does not have to be parallel to the axis of the cone; the hyperbola will be symmetrical in any case.

An asymptote of the curve y = f(x) or in the implicit form: f(x, y) = 0 is a straight line such that the distance between the curve and the straight line lends to zero when the points on the curve approach infinity.

In Mathematics, infinity is the concept describing something larger than the natural number. It generally refers to something without any limit. This concept is predominantly used in the field of Physics and Math which is relevant in a number of fields.

The quintessential example of asymptotes are the vertical or horizontal lines given by x=0 and y=0, respectively, relative to the graph of the real-valued function f(x)=1x f ( x ) = 1 x in the first quadrant.

In the cartesian system, the coordinate plane is divided into four equal parts by the intersection of the x-axis (the horizontal number line) and the y-axis (the vertical number line). These four regions are called quadrants because they each represent one-quarter of the whole coordinate plane.

Since the electrician charged $360 on a particular job, the number of hours that this electrician worked for is 4 hours.

In Mathematics, a linear function is sometimes referred to as an expression or the slope-intercept form of a straight line and it can be used to model (represent) the total amount of money that is being charged by this electrician;

T = mh + b

Where:

Therefore, the required linear function that represents the total amount of money that is being charged by this electrician per hour is given by this mathematical expression;

T = 80h + 40

When the total amount of money is $360, the number of hours worked by this electrician can be calculated as follows;

360 = 80h + 40

80h = 360 - 40
