With the help of congruency of triangles rules, we know that TSR ≅ QRS because of (B) the AAS congruence theorem.
What is the congruency of triangles?Two triangles are said to be congruent if all three corresponding sides and all three corresponding angles have the same size.
These triangles can be moved, turned, flipped, and rotated to produce the same appearance.
When moved, they are parallel to one another.
So, we have two sets of angles and one common side.
Review the congruence situations.
SSS ⇒ Three sides in the first, three sides in the second.
SAS: two sides, including the angle of the first side.
Incorporating angle in the second.
2 angles and the side that joins them in the first, according to ASA
Two angles and the side that connects the two angles.
AAS = 2 angles in the first triangle, plus 1 side.
Second, and one side in △.
Let's read the statements again and fill in the blanks.
Step 1: Since all right angles are congruent, mTSR = mQRS = 90°.
Step 2: Since it is given, mT = mQ
Step 3: Due to the reflexive property, SR becomes RS (common side)
Step 4: Because of the AAS congruence theorem, TSR and QRS are required.
Therefore, with the help of congruency of triangles rules, we know that TSR ≅ QRS because of (B) the AAS congruence theorem.

Find the 8th term.
Check the picture below.
Answer:
205.03125
Step-by-step explanation:
You want the 8th term of the sequence that begins 12, 18, 27, ....
DifferencesThe first differences of the given terms are ...
18 -12 = 6
27 -18 = 9
These are not constant, so the sequence is not an arithmetic sequence.
RatiosThe ratios of sequential terms are ...
18/12 = 1.5
27/8 = 1.5
These are constant, suggesting the sequence is an exponential sequence. The equation for the n-th term is ...
an = 12(1.5^(n-1))
Then the 8th term is ...
a8 = 12(1.5^7) = 205.03125

Additional comment
The sequence could be quadratic if the second differences are all 9-6=3. In that case, the equation for the n-th term is ...
an = 1.5n(n +1) +9
and the 8th term is ...
a8 = 1.5·8(8+1) +9 = 117

The product of matrix A and matrix B is matrix C
a) [tex]C = \begin{pmatrix}23\end{pmatrix}[/tex]
b) [tex]C = \begin{pmatrix}5\end{pmatrix}[/tex]
What is multiplication of matrices?
The product of two matrices A and B is defined if the number of columns of A is equal to the number of rows of B. The first matrix must have the same number of columns as the second matrix has rows. The number of rows of the resulting matrix equals the number of rows of the first matrix, and the number of columns of the resulting matrix equals the number of columns of the second matrix
Given data ,
a)
Let the first matrix be A
The value of A is
[tex]A = \begin{pmatrix}2&3\end{pmatrix}[/tex]
The value of second matrix B is
[tex]B = \begin{pmatrix}4\\ \:5\end{pmatrix}[/tex]
Now , the product of matrix A and matrix B is matrix C
The value of matrix C is
[tex]C = \begin{pmatrix}2&3\end{pmatrix}\begin{pmatrix}4\\ 5\end{pmatrix}[/tex]
On simplifying the value of matrix C , we get
[tex]C = \begin{pmatrix}2\cdot \:4+3\cdot \:5\end{pmatrix}[/tex]
[tex]C = \begin{pmatrix}23\end{pmatrix}[/tex]
Therefore , the value of matrix C is [tex]C = \begin{pmatrix}23\end{pmatrix}[/tex]
b)
Let the first matrix be A
The value of A is
[tex]A = \begin{pmatrix}1&2\end{pmatrix}[/tex]
The value of second matrix B is
[tex]B = \begin{pmatrix}-3\\ \:4\end{pmatrix}[/tex]
Now , the product of matrix A and matrix B is matrix C
The value of matrix C is
[tex]C = \begin{pmatrix}1&2\end{pmatrix}\begin{pmatrix}-3\\ 4\end{pmatrix}[/tex]
On simplifying the value of matrix C , we get
[tex]C =\begin{pmatrix}1\cdot \left(-3\right)+2\cdot \:4\end{pmatrix}[/tex]
[tex]C = \begin{pmatrix}5\end{pmatrix}[/tex]
Therefore , the value of matrix C is [tex]C = \begin{pmatrix}5\end{pmatrix}[/tex]

Graph the line with y-intercept -7 and slope 3/2
We are given the slope and the y-intercept so using the slope-intercept form:
y = mx + b, where m- slope, b- y-intercept.Substitute values to get:
y = (3/2)x - 7To graph a line we need two points, one is given, (0, - 7) - the y-intercept.
Find one more point, take even value of x to cancel the fraction, let it be x = 4, find its y-coordinate:
y = (3/2)*4 - 7 = 6 - 7 = - 1So our points are:
A(0, - 7) and B(4, - 1)Plot the points and connect to graph the line.
See below.
The graph of the linear equation:y = (3/2)*x - 7 can be seen in the image at the end.
How to graph the linear equation?A general linear equation is written as:y = a*x + b
Where a is the slope and b is the y-intercept. Then our linear equation is:y = (3/2)*x - 7
To graph it, we need to know two points in our line, to do so, we evaluate it in two different values of x. if x = 0y = (3/2)*0 - 7y = -7So we have the point (0, -7)
And if x = 2 then:y = (3/2)*2 - 7y = 3 - 7y = -4So we have the point (2, -4)

Tyler's savings account pays a simple annual interest rate of 3.25%. Suppose he deposits $5,000 in the
account and makes no additional deposits or withdrawals for 3 years. What will the total value of the account
be after 3 years?
Answer:
The total value of the account after 3 years will be $5,503.52.
Step-by-step explanation:
A loan or deposit's interest is computed using the starting principle and the interest payments from the ago decade as compound interest.
We know that the compound interest is given as
A = P(1 + r)ⁿ
Where A is the amount, P is the initial amount, r is the rate of interest, and n is the number of years.
Tyler's bank account pays a straightforward yearly financing cost of 3.25%. Assume he stores $5,000 in the record and sets aside no extra installments or withdrawals for a long time.
The total value of the account after 3 years will be calculated as,
A = $5,000(1 + 0.0325)³
A = $5,000 x (1.0325)³
A = $5,000 x 1.1007
A = $5,503.52
The total value of the account after 3 years will be $5,503.52.

The perimeter of the figure is 5.0.
What is a perimeter?
The perimeter of a two-dimensional shape is the distance around the outside of the shape. It is the sum of the lengths of all the sides of the shape. For example, the perimeter of a rectangle is the sum of the lengths of all four sides. The perimeter of a triangle is the sum of the lengths of all three sides.
To reflect a point across the line y=x, we can use the following formula:
(x', y') = (y, x)
Where (x', y') is the reflected point and (x, y) is the original point.
Using this formula, we can find the coordinates of the reflected points A' and B':
A' = (4, 4) -> (4, 4) -> (4, 4)
B' = (5, -1) -> (-1, 5) -> (-1, 5)
Therefore, the image of AB is A'B' with endpoints A'(4, 4) and B'(-1, 5).
To find the perimeter of the figure formed by the segments AB, B'B, and A'B', we can add up the lengths of these three segments. The length of AB can be found using the distance formula:
[tex]AB = \sqrt{((5-4)^2 + (-1-4)^2)}\\\\= \sqrt{(1^2 + (-5)^2)}\\\\= \sqrt{(1 + 25)}\\\\= \sqrt{26}[/tex]
The length of B'B can be found using the same formula:
[tex]B'B = \sqrt{((-1-(-1))^2 + (5-5)^2)}\\\\= \sqrt{(0^2 + 0^2)}\\\\= 0[/tex]
The length of A'B' can also be found using the distance formula:
[tex]A'B' = \sqrt{((-1-4)^2 + (5-4)^2)}\\\\= \sqrt{(-5)^2 + (1)^2}\\\\= \sqrt{25 + 1}\\\\= \sqrt{26}[/tex]
The perimeter of the figure is AB + B'B + A'B' = √26 + 0 + √26 = 2√26. To the nearest tenth, this is 5.0.
Hence, the perimeter of the figure is 5.0.

Congruent triangles are two triangles that are the same size and shape. Two congruent triangles remain congruent even if we flip, turn, or rotate one of them.Two triangles must have the same angles and, as a result, must be congruent if their sides are the same. If two triangles are congruent or not, we may determine this simply by looking at their sides.These two triangles are also equivalent if we know that two sides of one triangle and the angle between them are congruent to two sides and the angle between them of another triangle.ΔABC ~ ΔQRS

what is percentage ?By dividing the value by the entire value and multiplying the result by 100, one can compute the percentage. The formula for calculating percentage is (value/total value)100%.When a piece of a whole is stated as a percentage, it is not a fraction but rather a number between 0 and 100. There are three percentages: 100% for everything, 50% for half of it, and 0% for the remaining portion.
calculation
25% of new students come from one-parent households, which equals 0.25;
75% of new students come from two-parent households, which is 0.75.
42% of incoming students from homes with only one parent go on to complete their college studies = 0. 42
58 percent of incoming students who come from two-parent households go on to complete their education =0.58
= 0.25 * 0.42 + 0.75 * 0.58 = 0.54 = 54%.
Whereas students from single parent or two parent homes make up 54% of new students, these students eventually go on to complete their college studies..

In a hypothesis test for population proportion, you calculated the p-value is 0.01 for the test statistic, which is a correct statement of the p-value?Group of answer choicesa)The p-value indicates that it is very rare to observe a test statistics equally or more extreme when the null hypothesis is true.b)The p-value indicates that it is very likely to observe a test statistics equally or more extreme when the null hypothesis is true.c)The p-value is calculated assuming the alternative is true.
a) The p-value indicates that it is very rare to observe a test statistics equally or more extreme when the null hypothesis is true.
What is null hypothesis?A null hypothesis is a claim or presumption that there is no association between two observed variables or that observed differences between groups are the result of chance. It is frequently employed in statistical testing, and it is represented by the symbol "H0". The null hypothesis is often the inverse of the alternative hypothesis, which posits a link or difference between the variables. To reject the null hypothesis, the observed data must be statistically significant and unlikely to have occurred by chance. In scientific research, the null hypothesis is crucial because it enables researchers to assess the significance of their data and reach reliable conclusions.
