For each statement, write what would be assumed and what would be proven in a proof by contrapositive of the statement. Then write what would be assumed and what would be proven in a proof by contradiction of the statement.
a. If x and y are a pair of consecutive integers, then x and y have opposite parity.
b. For all integers n, if n² is odd, then n is also odd.
Answer:
a)
Given Statement - If x and y are a pair of consecutive integers, then x and y have opposite parity.
Proof by Contrapositive:
Assumed statement: Suppose that integers x and y do not have opposite parity.
Proven Statement: x and y are not a pair of consecutive integers.
Proof -
x = 2u₁ , y = 2u₂
Then
(x, x+1) = (2u₁ , 2u₁ + 1) = (Even, odd)
If y = 2u₁ + 1
Not possible
⇒x and y are not a pair of consecutive integers.
Hence proved.
Proof by Contradiction:
Assumed statement: Suppose x and y are not a pair of consecutive integers.
Proven Statement: Suppose x and y do not have opposite parity.
Proof -
If x and y are not a pair of consecutive integers.
⇒ either x and y are odd or even
If x and y are odd
⇒x and y have same parity
Contradiction
If x and y are even
⇒x and y have same parity
Contradiction
(b)
Proof by Contrapositive:
Assumed statement: Let n be an integer such that n is not odd (i.e. n is an even integer)
Proven Statement: n² is not odd (i.e n² is even)
Proof -
Let n is even
⇒n = 2m
⇒n² = (2m)² = 4m²
⇒n² is even
Hence proved.
Proof by Contradiction:
Assumed statement: Let n be an integer such that n² be odd.
Proven Statement: suppose that n is not odd (i.e n is even)
Proof -
Let n² is odd
⇒n² is even
⇒n² = 2m
⇒2 | n²
⇒2 | n
⇒n = 2x
⇒ n is even

Answer:
2,540 miles
Step-by-step explanation:
The computation of the fewer miles is given below;
For Space explorer B
= 15,000 miles ÷ 5 hours
= 3,000 miles per hour
For space explorer A
y = 4,600 x
That means in one hour it covered 460 miles
So, the fewer miles would be
= 3,000 - 460
= 2,540 miles
The senior class is making T-shirts as a fundraiser. The material needed to make each T-shirt costs $3.75. The students sell each shirt for $10.To increase sales, the students spend $350 on advertising. How many t-shirts must the students sell to breakeven?
Answer:
the number of t-shirts sold to breakeven is 56 t-shirts
Step-by-step explanation:
The computation of the number of t-shirts sold to breakeven is shown below:
= Fixed cost ÷ (Selling price - cost price)
= $350 ÷ ($10 - $3.75)
= $350 ÷ 6.25
= 56 t-shirts
Hence, the number of t-shirts sold to breakeven is 56 t-shirts

In triangle ABC, one angle measures 68°, another measures 19°, what is the measure of the third angle? *
Answer:
93°
Step-by-step explanation:
In triangle ABC
one angle = 68°
Another angle = 19°
Let the third angle be X Then
x + 68° + 19° = 180° { being sum of angles of triangle }
x = 180° - 87°
x = 93°
The measure of the third Angle is 93°

Ms. Halloween works in a factory. She receives a salary of $9.10 per hour and piecework pay of 15 cents per unit produced. Last week she worked 40 hours and produced 988 units. a. What was her piecework pay? What was her total hourly pay for the week? What was her total pay for the week? b. If her boss offered to pay her a straight $13 per hour and no piecework pay for the week, would she earn more or less than under the piecework pay system? c. What would her total weekly salary have been if she produced 0 units?
Answer:
1065.1
Step-by-step explanation:
Part a:
1. Halloween's piecework pay = $148.20
2. Halloween's total hourly pay for the week = $364
3. Halloween's total pay for the week = $512.20
Part b:
Total amount received for the week = $520 and she earns more when she get the straight salary on hourly basis.
Part c:
Halloween's hourly pay for 0 units production = $364
What is a salary?
Salary is a compensation or fixed amount of money paid to an employee by an employer in return for work performed.
For the given situation,
Halloween's salary received per hour = $9.10
Halloween's piecework pay per unit = 15 cents
Total work per week = 40 hours
Total unit produced per week = 988 units.
Part a:
1. Halloween's piecework pay = [tex](988)(15)[/tex]
⇒ [tex]14820 cents[/tex]
we know that $1 = 100 cents
⇒ [tex]\$148.20[/tex]
2. Halloween's total hourly pay for the week = [tex](40)(9.10)[/tex]
⇒ [tex]\$364[/tex]
3. Halloween's total pay for the week = [tex]364+148.20[/tex]
⇒ [tex]\$512.20[/tex]
Part b:
Halloween's boss offered to pay her a straight $13 per hour and no piecework pay for the week.
Total amount received for the week = [tex](40)(13)[/tex]
⇒ [tex]\$520[/tex]
Difference in pay = [tex]520-512.20[/tex]
⇒ [tex]\$7.80[/tex]
Thus, she earns more when she get the straight salary on hourly basis.
Part c:
If her production is 0 units, then she might get her hourly pay only.
⇒ [tex](40)(9.10)[/tex]
⇒ [tex]\$364[/tex]Hence we can conclude that
Part a:
1. Halloween's piecework pay = $148.20
2. Halloween's total hourly pay for the week = $364
3. Halloween's total pay for the week = $512.20
Part b:
Total amount received for the week = $520 and she earns more when she get the straight salary on hourly basis.
Part c:
Halloween's hourly pay for 0 units production = $364

The correct reason for the statement ∠1 ≅ ∠2 will be;
⇒ Definition of Vertical Angles.
Option D is true.
What is Vertical angles?
When the two lines are crosses to each other at a point then the vertical angles are formed.
Given that;
∠1 and ∠2 are formed between two lines which crosses at a point.
Now,
The two lines are vertical lines which passes through a point and ∠1 and ∠2 are formed between them.
So, By definition of Vertical Angles;

The table shows Alice's age (a) and her daughter Martha's age (m). Complete the table and the equation.
Alice’s Age in Years
(a) Martha’s Age in Years
(m)
28 6
33 _
37 15
41 19
48 _
This equation relates Alice’s and Martha's ages in years.
Alice’s age (a) = Martha’s age (m) + _
Answer:
33-11
48-26
Alice’s age (a) = Martha’s age (m) + 22
Step-by-step explanation:
In order to find the blank spots you would need to find the difference in the filled spots. We are trying to figure out the difference which is subtraction.
28 - 6 = 22
To make sure we are correct we would do another problem.
37 - 15 = 22
So in order to find Martha's age when Alice was 33, we would subract 22.
33 - 22 = 11
Same when Alice was 48.
48 - 22 = 26
And the last equation is asking the difference between them, which would be 22.
Answer: 11 and 26

prove that Sn=n(n+1) for the sequence an=2n,where n is any positive integers
Answer:
Proved
Step-by-step explanation:
Given
[tex]a_n = 2n[/tex]
Required
Prove that [tex]S_n = n(n+1)[/tex]
The given sequence is an arithmetic sequence.
The Sn of this sequence is:
[tex]S_n = \frac{n}{2}(a_1 + a_n)[/tex]
Calculate a1
[tex]a_n =2n[/tex]
[tex]a_1 =2*1[/tex]
[tex]a_1 =2[/tex]
So, we have:
[tex]S_n = \frac{n}{2}(a_1 + a_n)[/tex]
[tex]S_n = \frac{n}{2}(2 + 2n)[/tex]
Factor out 2
[tex]S_n = \frac{n*2}{2}(1 + n)[/tex]
