The given statement "when a transversal crosses two parallel lines, Corresponding angles are created, which are congruent to one another" is TRUE.

The angles created when a transversal intersects two parallel lines are known as corresponding angles.

Typical examples of equivalent angles include opening and closing a lunchbox, resolving a Rubik's cube, and endless parallel railroad tracks.

Angles that are equal in size and are found on the same side as the transversal line are called corresponding angles.

In geometry, corresponding sides and corresponding angles of polygons are compared as part of the tests for congruence and resemblance.

In these tests, the order of adjacency is maintained by pairing each side and each angle of one polygon with a side or angle of the other polygon.

Therefore, the given statement "when a transversal crosses two parallel lines, Corresponding angles are created, which are congruent to one another" is TRUE.

The x-intercepts of the graph of the equation are (8,0) and (-6,0).

What are intercepts?

A point on the y-axis known as an intercept is where the line's slope passes.

X-intercept and Y-intercept are the two main intercepts. The line's x-intercept and y-intercept are located where the line crosses the x and y axes, respectively.

Now, in order to find the x- intercepts, we need to put y=0 because at that point the line crosses the x- axis and therefore, y=0 at that point.

So,

x^2-2x+(0)^2-3(0)=48

⇒x^2-2x=48

⇒x^2-2x-48=0

⇒x^2+6x-8x-48=0

⇒x(x+6)-8(x+6)=0

⇒(x-8)(x+6)=0

So, x= 8,-6

Hence, the x-intercepts of the graph of the equation are (8,0) and (-6,0).

The degree of the function is 3, and the end behavior is that as x gets very large or very small the function increases or decreases without bound respectively.

Generally, The degree of a polynomial function is the highest power of the variable in the function. In this case, the highest power of x is 3, so the degree of the function is 3.

The end behavior of a polynomial function refers to how the function behaves as the value of x gets very large or very small (i.e., as x approaches positive or negative infinity).

To find the end behavior, we look at the leading term, which is the term with the highest degree. In this case, the leading term is 3x³. Since the coefficient of x³ is positive, the end behavior of the function as x approaches positive infinity is positive infinity, and as x approaches negative infinity, the end behavior of the function is negative infinity.

The required probability is 7/18 that an eighth grader chosen at random will play the keyboard.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

The total number of eighth-grade students in the School of Rock is 12 + 6 + 4 + 14 = 36 students.

The number of eighth-grade students playing the keyboard is 14 students.

So, the probability that an eighth grader chosen at random will play the keyboard is :

a. The probability that X is less than 95 is approximately 0.0668

b. The probability that X is between 95 and 97.5 is approximately 0.1359

c. The probability that X is above 102.2 is approximately 0.0228

d. The value of X for 65% chance is 99.23

We know, z=(X-mean)/ (S.D./sqrt N)

Thus, putting in the values for the respective cases, we get

(a) z value corresponding to X=95 is,

z=(95-100)/(10/sqrt 25)= -2.5

Therefore, required probability= area under the standard normal curve left to

z= -2.5 = 0.5000- 0.4938= 0.0062

(b) z value corresponding to X=95 is -2.5 and X=97.5 is,

z=(97.5-100)/(10/sqrt 25)= -1.25

Therefore, required probability= area under the standard normal between

z= -2.5 and z= -1.25= 0.4938- 0.3944= 0.0994

(c) z=(102.2-100)/(10/sqrt 25)= 1.1

Therefore, required probability= area under the standard normal curve right to

z= -2.5 = 0.5000- 0.3643= 0.1357

(d) 65%= 0.6500 is an area on the left side of the z value.

Or, we can say 35%= 0.3500 is on the right side of the z value.

therefore, the corresponding z value is -0.385 approximately.

Thus, for X value,

-0.385= (X-100)/(10/sqrt 25)

-0.385= (X-100)/2

-0.77= X-100

To determine the probability that the sample mean for French is greater than that of the Americans, we need to use the Central Limit Theorem, which states that as the sample size increases, the distribution of the sample means will become more and more normal, regardless of the distribution of the population from which the samples are drawn.

So, we can assume that the sample means of both American and French adults will be normally distributed with a mean of 43.5 hours/week and 36 hours/week respectively and a standard deviation of 4.6/sqrt(110) and 5.1/sqrt(135) respectively.

We can use these assumptions and the Z-score formula to find the probability that the sample mean for French is greater than that of Americans.

Z = (36 - 43.5) / (sqrt((4.6/sqrt(110))^2 + (5.1/sqrt(135))^2))

The resulting Z-score will be negative, meaning that the probability that French sample mean is greater than American sample mean is low and it's a rare event.

The Gold Standard was a system under which nearly all countries fixed the value of their currencies in terms of a specified amount of gold, or linked their currency to that of a country which did so.

Step-by-step explanation:

Answer:

No longer used.

Step-by-step explanation:

Due to too much paper money being printed, some countries did not have enough gold reserves to exchange for the excessive amounts of paper promissory notes. (China's overprinting of printed money during the 9th and 15th centuries foreshadowed England's overprinting during WWI some 200 years later.) This rendered the paper money worthless. (One of the causes of the Great Depression.)

The gold standard is no longer used now, but the system it inspired is currently used between nations.

The expression is equal to f(x) g(x) is 77x⁷ + 78x⁶ - 27x⁵

A function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

In order to find which expression is equal to f(x) g(x), multiply (11x³ - 3x²) by (7x⁴ + 9x³). That is:

f(x) g(x) = (11x³ - 3x²)(7x⁴ + 9x³)

Expand the expression:

f(x) g(x) = 11x³ × 7x⁴ + 11x³ × 9x³ - 3x² × 7x⁴ - 3x² × 9x³

f(x) g(x) = 77x⁷ + 99x⁶ - 21x⁶ - 27x⁵

Answer: The solution to the expression is the result of the mathematical operations being performed in the correct order. The order of operations is: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

5/34 is a fraction, 22 2/3 is a mixed number, and 2 1/9 is also a mixed number. To perform the operations, we need to convert all these mixed numbers to fractions.

So, 22 2/3 is equal to (223+2)/3 = 68/3

and 2 1/9 is equal to (29+1)/9 = 19/9

Now the expression become 5/34 x 68/3 - 19/9

We can now perform the operations:

5/34 x 68/3 - 19/9

= (568)/(343) - 19/9

= 340/102 - 19/9

Now we have to perform subtraction, for this we need to have a common denominator:

= (3409 - 19102)/(102*9)
