Answers
The best statement and reason that completes the proof is option D that is,
statement- 2. ∠1 is supplementary to ∠2
reason- 2. linear pair theorem
To prove ∠1 ≅ ∠ 3, we can use the congruent supplements theorem. According to the congruent supplements theorem, If two angles are supplements of the same angle then two angles are congruent.
Line a and line b intersect (given)
∠3 is supplementary to ∠2 because of linear pair theorem (given)
So, if we take ∠2 as the common angle
And ∠1 is supplementary to ∠2 by linear pair theorem ( option D)
Then, ∠1 is supplementary to ∠2 which is supplementary to ∠3
Therefore, ∠1 ≅ ∠3 (according to the congruent supplements theorem)
Hence proved.
Therefore, the best statement and reason that completes the proof is
statement- 2. ∠1 is supplementary to ∠2
reason- 2. linear pair theorem

Option D, which is the following, is the finest statement and justification for concluding the proof.
statement 2. 1 is an addition to 2
2. The linear pair theorem
We can apply the congruent supplements theorem to demonstrate 1 and 3. The congruent supplements theorem states that two angles are congruent if they are supplements of the same angle.
Lines a and b come together (given)
Because of the linear pair theorem, 3 is an addition to 2 (given)
Thus, if we consider 2 to be the common angle
And the linear pair theorem enables 1 to be an addition to 2 ( option D)
Then, 1 is an addition to 2 which is an addition to 3
Consequently, 1 + 3 (according to the congruent supplements theorem)
So it was proved.
As a result, the strongest argument and supporting evidence are
statement 2. 1 is an addition to 2
2. The linear pair theorem

You want the greatest common factor of the terms {98ab^3, 84a, 140b, 112ab}.
Common factorsThere are no variables that are common to all terms. 'a' and 'b' are each common to 3 of the 4 terms, but not all.
The greatest common factor of the constants cannot be larger than the smallest difference of the constants. That difference is ...
98 -84 = 112 -98 = 14

Answers
With the partial product method the multiplication answer is 4725.
According to the statement
We have to find that the by which strategy for multiplying 75 and 63 should result In the correct product.
So, For this purpose, we know that the
The partial product method involves multiplying each digit of a number in turn with each digit of another where each digit maintains its place.
From the given information:
We have to multiply the numbers 75 and the 63.
Then
According to the above written strategy,
75 = 70+5 and
63 = 60+3
Then
75*63 = (70*60) + (70*3) + (5*60) + (5*3)
then solve it
75*63 = (4200) + (210) + (300) + (15)
75*63 = 4410 + 315

In a recent awards ceremony, the age of the winner for best actor was 31 and the age of the winner for best actress was 42. For all best actors, the mean age is 42.4 years and the
standard deviation is 8.2 years. For all best actresses, the mean age is 31.6 years and the standard deviation is 10.3 years. (All ages are determined at the time of the
awards ceremony.) Relative to their genders, who had the more extreme age when winning the award, the actor or the actress? Explain.
Since the z score for the actor is z= and the z score for the actress is z-, the
had the more extreme age.
Answers
So the best actor's age deviates from the mean, he receives the award at the most extreme age.
What is defined as the z score?The z-score of a way of measuring X in a set with mean and standard deviation is given by: z = (x - μ)/σ.The Z-score indicates how far the measure deviates from the mean. After determining the Z-score, we examine the z-score table to determine the p-value connected with this z-score. This p-value represents the probability also that measure's value is less than X, or the percentile of X. Subtracting 1 from the p-value yields the probability that measure's value is greater than X.In response to this question:
Whichever z-score does have the highest absolute value, such that, the one that deviates the most from the mean, has a most extreme age.
Best actor: 31 years old, so.
The mean age of the best actors is 42.2 years, with a standard deviation of 8.2 years.
z = (x - μ)/σ
Put the values;
z = (31 - 42.2)/ 8.2
z = -1.36
Best actress:
So, at the age of 42,
The mean of the best actresses is 31.6 years, with a standard deviation of 10.3 years.
z = (x - μ)/σ
Put the values;
z = (42 - 31.6)/10.3
z = 1.01
Thus, Because the best actor's age is further from the mean, he has the most extreme age when receiving the award.

The length of a certain rectangle is 10m greater than twice its width. If the width were reduced by 20m and the length increased by 100m, the perimeter of the new rectangle would be twice the perimeter of the original rectangle. What are the dimensions of the original rectangle?
Answers
The dimensions of the original rectangle is a length of 56.66 meter and width of 23.33 meter.
What is perimeter?Perimeter is the sum of all the sides of a two dimensional polygon or shape.
For first rectangle let x represent width:
Length = 2x + 10; width = x
Perimeter = 2(length + width)
Perimeter = 2(2x + 10 + x) = 6x + 20
For second rectangle:
Length = 2x + 10 + 100 = 2x + 110; width = x - 20
Perimeter = 2(length + width)
Perimeter = 2(2x + 110 + x - 20) = 6x + 180
the perimeter of the new rectangle would be twice the perimeter of the original rectangle. Hence:
6x + 180 = 2(6x + 20)
x = 23.33 m, length = 2x + 10 = 56.66
