Step-by-step explanation:

When a transversal cuts two parallel lines, 8 angles are created.

When two lines do not cross one another, they are said to be parallel. In addition, parallel lines are two lines that cross each other at infinity.

A transversal line is one that crosses two other lines at two different locations. Line l meets a and b in the image below at two different locations, P and Q. Line l is the transversal line as a result.

Corresponding angles are those that are created when two parallel lines and a transversal intersect, also known as matching corners or corresponding corners.

∠1 and ∠6

∠4 and ∠8

∠2 and ∠5

∠3 and ∠7

When a transversal connects two coplanar lines, alternate interior angles are created.

∠4 and ∠5

∠3 and ∠6

However, each pair of alternate interior angles is equal if a transversal meets two parallel lines.

∠4 = ∠5

∠3 = ∠6

The pair of angles that are created on the outer side of two lines but on the other side of the transversal are known as alternate exterior angles.

Consecutive interior angles, related angles, and co-interior angles are other names for interior angles that are on the same side of the transversal.

Step-by-step explanation:

The median of the set of numbers 18, 16, 12, and 14 is 15. This is the average of the two middle numbers in the ordered set, and it is not affected by extreme values or outliers.

The median of a set of numbers is the value that is exactly in the middle of the set when it is ordered from least to greatest. In this case, the set of numbers is 18, 16, 12, and 14. When we order this set from least to greatest, we get 12, 14, 16, and 18. There are four numbers in this set, so the median is the average of the two middle numbers. The two middle numbers in this set are 14 and 16, so the median is (14 + 16) / 2 = 15.

To find the median, we first need to arrange the numbers in order from least to greatest. If there is an odd number of numbers in the set, the median is the middle number. If there is an even number of numbers in the set, the median is the average of the two middle numbers. In this case, there are four numbers in the set, so the median is the average of the two middle numbers.

In summary, the median of the set of numbers 18, 16, 12, and 14 is 15. This is the average of the two middle numbers in the ordered set, and it is not affected by extreme values or outliers.

What is the property of commutativity?

The rule governing the ordering of variables is the commutative property. It states that the order of the variables does not influence the final answer when they are added or multiplied.

What is the property of associativity?

The associative feature of real numbers relates to grouping variables. It states that altering the grouping of variables added to or multiplied by one another has no effect on the output.

In mathematics, what is a distributive property?

This property states that multiplying the sum of two or more addends by a number yields the same result as multiplying each addend separately by the number and then putting the resulting products together.

(a) The probability of obtaining two rods of the desired length is (100/200) * (99/199) = 0.495.

This can be found by using the formula for independent events:

P(A and B) = P(A) * P(B)

Since the two draws are of rods without replacement,

the probability of the first-rod being of the desired length = 100/200 (there are 100 desired-length rods out of a total of 200).

The probability of the second-rod being of the desired length = 99/199 (since one of the desired length rods has already been drawn). Multiplying these two probabilities gives us the answer.

(b)The probability of obtaining exactly one rod of the desired length

=(100/200) * (100/199) + (100/200) * (100/199)

= 0.990.

This can be found by using the formula for the union of two events: P(A or B) = P(A) + P(B).

Since the two draws are rods without replacement, the first draw has a probability of 100/200 of being of the desired length (there are 100 desired-length rods out of a total of 200).

The probability of the second draw being of the desired length is 100/199 (since one of the desired length rods has already been drawn). Adding these two probabilities gives us the answer.

(c) The probability of obtaining none of the desired length is (50/200) * (50/199) = 0.015.

This can be found by using the formula for independent events

: P(A and B) = P(A) * P(B).

Since the two draws are of rods without replacement, the probability of the first-rod being of the undersized length is 50/200 (there are 50 undersized rods out of a total of 200).

The probability of the second-rod being of the undersized length is 50/199 (since one of the undersized rods has already been drawn). Multiplying these two probabilities gives us the answer.

Two months would pass before they received the same sum of money.

In mathematics, equivalence is a relationship that states that two quantities have the same value or that two mathematical expressions reflect the same mathematical object. A = B is the symbol for the equality of A and B, and it is also pronounced as A = B.

Total amount saved = amount started with + (amount deposited per month x number of months)

Amount saved by Tonya = $60 + $20m

Amount saved by Jull = $20 + $40m

The two aforementioned equations would be equivalent if they both saved the same amount of money:

60 + 20m = 20 + 40m

Take the below actions to find the value of m:

60 - 20 = 40m - 20m

40 = 20m

m = 40 / 20

m = 2

The value of x is 2 and y is -7/2 in the equations 2y = x + 9 and 2y − 11 = 2x.

The elimination approach involves taking one variable out of the system of linear equations by utilizing addition or subtraction together with multiplication or division of the variable coefficients. Because it allows us to remove one of the variables and solve a more straightforward equation. The elimination approach may also be referred to as the addition method or the linear combination method in some texts. This is due to the fact that we'll be adding two equations together.

Given,

Equations,

2y = x + 9

2y − 11 = 2x

Rearranging variables and constant

Using elimination method,

x - 2y = 9

2x - 2y = 11

-----------------

x = 2

Equating x = 2 in equation 1

x - 2y = 9

-2y = 9 - 2

-2y = 7

y = -7/2

Step-by-step explanation:

You have a rectangle with sides 365 and 276 miles, and you want to know the perimeter. (This is an approximation of the state of Wyoming.)

The perimeter of a rectangle is the sum of its side lengths. The formula is ...

  P = 2(L +W)

  P = 2(365 +276) = 2(641)

  P = 1282

The perimeter of Wyoming is about 1282 miles.

The vertex of the graph of f(x) = |x + 8| - 3 is (-8, -3). It lies in the third quadrant.

Therefore the answer is (-8, -3).

Simplifying the given graph to the form f(x) = a|x - h| + k

f(x) = |x + 8| - 3

f(x) = 1 × |x + 8| - 3

where a = 1, h = -8, k = -3

So f(x) = |x + 8| - 3 is symmetrical about the line x = -8. At x = -8, y = -3.

Therefore, the vertex of the graph is (-8, -3).
