How do you prove a contrapositive?
Answer:
Step-by-step explanation:
A contrapositive is a logical equivalent of the original statement that has the opposite direction and negated conclusion. It can be proven by using the following steps:
Start with the original statement in the form of "If P, then Q".
Negate both the hypothesis (P) and the conclusion (Q) of the original statement.
Conjoin the negated hypothesis and the negated conclusion to form a new statement.
Show that the contrapositive is logically equivalent to the original statement, meaning that it has the same truth value as the original statement for all possible cases.
For example, consider the statement: "If it rains, the roads will be wet." The contrapositive of this statement is "If the roads are not wet, it did not rain." To prove the contrapositive, we can use the following steps:
Start with the original statement "If it rains, the roads will be wet."
Negate both the hypothesis and the conclusion: "It does not rain" and "The roads are not wet".
Conjoin the negated hypothesis and the negated conclusion: "It does not rain and the roads are not wet."
Show that the contrapositive is logically equivalent to the original statement by considering all possible cases:
If it rains, the roads will be wet (as stated in the original statement), and the contrapositive "It does not rain and the roads are not wet" is false.
If it does not rain, the roads will not be wet (as stated in the contrapositive), and the original statement "If it rains, the roads will be wet" is false.
This shows that the contrapositive is logically equivalent to the original statement, and we can use it to draw the same conclusion with a different proof.
Explain why you can write the product (26) 23• (26) 15as the single power (26) 38 .
The reason [tex]26^{23[/tex] x [tex]26^{15[/tex] can be written as [tex]26^{38[/tex] because both have same base and power get added.
What are Exponents and power?Exponents and powers can be used to represent extremely big or extremely small numbers in a more straightforward fashion.
For example, if we have to show 3 x 3 x 3 x 3 in a simple way, then we can write it as [tex]3^4[/tex], where 4 is the exponent and 3 is the base.
Given:
We have [tex]26^{23[/tex] x [tex]26^{15[/tex]
Now, using the property of exponents and power if the base of number same and in relation of multiplication then the power get added.
So, [tex]26^{23[/tex] x [tex]26^{15[/tex]
= [tex]26^{23 + 15[/tex]
and, 23+ 15 = 38
= [tex]26^{38[/tex]

Speedy Auto Repairs uses a job-order costing system. The company's direct materials consist of replacement parts installed in customer vehicles, and its direct labor consists of the mechanics' hourly wages. Speedy's overhead costs include various items, such as the shop manager's salary, depreciation of equipment, utilities, insurance and magazine subscriptions and refreshments for the waiting room.
The company applies all of its overhead costs to jobs based on direct labor-hours. At the beginning of the year, it made the following estimates:
Direct labor-hours required to support estimated output $12,000
Fixed overhead cost $114,000
Variable overhead cost per direct labor-hour $1.00
Required:
1. Compute the predetermined overhead rate.
2. During the year, Mr. Wilkes brought in his vehicle to replace his brakes, spark plugs, and tires. The following information was available with respect to his job:
Direct materials $626
Direct labor cost $292
Direct labor hours used 4
Compute Mr. Wilkes' total job cost.
3. If Speedy establishes its selling prices using a markup percentage of 40% of its total job cost, then how much would it have charged Mr. Wilkes?
(1) The predetermined overhead rate is $10.50 per direct labor-hour.
(2) Mr. Wilkes' total job cost is $960.
(3) Speedy Auto Repairs would have charged Mr. Wilkes $1344 for the job.
1) To compute the predetermined overhead rate, we need to add the fixed and variable overhead costs, and then divide by the estimated direct labor-hours:
$114,000 + ($1.00 * 12,000) = $126,000
Predetermined overhead rate = $126,000 / 12,000 = $10.50 per direct labor-hour
2) To find Mr. Wilkes' total job cost, we need to add up the costs of the direct materials and direct labor, and then apply the predetermined overhead rate to the direct labor hours used:
Direct materials cost: $626
Direct labor cost: $292
Total direct costs: $626 + $292 = $918
Overhead cost: $10.50 * 4 = $42
Total job cost: $918 + $42 = $960
3) To find the selling price, we need to add a markup of 40% of the total job cost:
Total job cost: $960
Markup: 40% * $960 = $384
Selling price: $960 + $384 = $1344
So, Speedy Auto Repairs would have charged Mr. Wilkes $1344 for the job.

Step 1: –10 + 8x < 6x – 4 Step 2: –10 < –2x – 4 Step 3: –6 < –2x Step 4: ________ What is the final step in solving the inequality –2(5 – 4x) < 6x – 4?
Answer: The final step in solving the inequality -2(5 - 4x) < 6x - 4 would be to isolate x on one side of the inequality. In the previous step (-6 < -2x), we have -2x on one side of the inequality and -6 on the other. To isolate x, we divide both sides of the inequality by -2:
-6 ÷ -2 < -2x ÷ -2
Since dividing by a negative number reverses the inequality direction, we get:
3 > x
So, the final solution to the inequality -2(5 - 4x) < 6x - 4 is x > 3. This means that all values of x that are greater than 3 satisfy the inequality.

is the value of Y+6 greater in4(y+6)=48 or 12(y+6)=48 how do you know?
To determine which expression has a greater value for Y + 6, we need to isolate Y + 6 on one side of the equation and compare the two expressions.
Starting with 4(y + 6) = 48, we can distribute the 4 to get 4y + 24 = 48. Subtracting 24 from both sides gives us 4y = 24, and then dividing both sides by 4 gives us y = 6. So, for this expression, the value of Y + 6 is 6 + 6 = 12.
Next, for 12(y + 6) = 48, we can distribute the 12 to get 12y + 72 = 48. Subtracting 72 from both sides gives us 12y = -24, and then dividing both sides by 12 gives us y = -2. So, for this expression, the value of Y + 6 is -2 + 6 = 4.
Therefore, the value of Y + 6 is greater in 4(y + 6) = 48 than in 12(y + 6) = 48.
Answer:
The value of y + 6 is greater in the first equation.
----------------------------
Divide both sides of the first equation by 4:
4(y + 6) = 48y + 6 = 12Divide both sides of the second equation by 12:
12(y + 6) = 48y + 6 = 4As we see the first expression has greater value since 12 > 4.

Based on the results of the survey, the assistant will construct a 95% confidence interval for the proportion of all customers who are satisfied. The marketing manager, however, says that the firm can afford to survey only 250 customers. How will this decrease in sample size affect the margin of error and confidence interval? True Statements or False Statements
False: The decrease in sample size will increase the margin of error and decrease the confidence interval.
What is interval?Interval is a set of values that are located between two specific points on a line. It can be used to measure the amount of time between two events, the difference between two numbers, or the distance between two points. Intervals can also be used in data analysis to identify patterns or trends. In mathematics, intervals are often represented as a pair of numbers, such as (1, 5).
The decrease in sample size will decrease the margin of error and increase the confidence interval. This is because when the sample size is decreased, the margin of error is increased and the confidence interval is decreased since the precision of the estimate is lower. This means that the range of the confidence interval is wider and the estimates are less precise.

Answer:

Step-by-step explanation:
ΔABC is a right-angled triangle where:
∠C = 90°
Sum of interior angles in any triangle = 180°
Therefore:
x° + 2x° + 90°= 180°
3x° + 90° = 180°
3x° = 180° - 90°
3x° = 90°
x = [tex]\frac{90}{3}[/tex]
∴Value of x = 30
Answer:
[tex]x[/tex] is equal to [tex]30\textdegree[/tex]
Step-by-step explanation:
The sum of the interior angles in a triangle is 180 degrees. This is because a triangle is a polygon with three sides and three angles, and the sum of the angles in any polygon can be found by using the formula:
sum of interior angles = (n - 2) x 180 degrees
Note: n is the number of sides.
A triangle has 3 sides. So substituting 3 in for n gives us
(3 - 2) x 180 degrees = 180 degrees
So the sum of the interior angles in a triangle is always 180 degrees.
In this example we can say that [tex]\angle A +\angle B+ \angle C=180\textdegree[/tex]
We are given a right triangle. A right angle is equal to 90 degrees.
We can conclude that
[tex]x+2x+90=180[/tex]
Lets solve for [tex]x[/tex].
Subtract 90 from both sides.
[tex]x+2x=180-90[/tex]
[tex]x+2x=90[/tex]
Add [tex]x[/tex] and [tex]2x[/tex].
[tex]3x=90[/tex]
Divide both sides by 3.

What is a fraction?Fraction is a mathematical term, which represents the portion or sub-parts of the whole thing. Basically, It has two parts: numerator and denominator.
Numerator is a number which lies on the top side, it indicates the number of equal parts taken and denominator is on the bottom side, it indicates the equal parts of the whole number.
To find the fraction of the box that Evangeline puts in each bowl, we need to divide the total amount of nuts in the box by the number of bowls.
The amount of nuts she has is 3/5 of a box.
To find the amount of nuts in each bowl, we need to divide 3/5 by 6:
(3/5) ÷ 6
To divide by a fraction, we can multiply by its reciprocal:
= (3/5) ÷ (6/1)
= (3/5) x (1/6)

The measure of one interior angle of a parallelogram is 0. 25 times the measure of another angle.
If the measure of one interior angle of a parallelogram is 0.25 times the measure of another angle, let's call the measure of the larger angle "x". Then, the measure of the smaller angle would be 0.25x.
In a parallelogram, opposite angles are equal in measure. So, if one angle measures x, the opposite angle would also measure x. And if one angle measures 0.25x, the opposite angle would also measure 0.25x.
Therefore, the sum of the measures of the angles in a parallelogram would be x + x + 0.25x + 0.25x = 2x + 0.5x = 2.5x.
Since the sum of the measures of the interior angles in a parallelogram must equal 360 degrees, we can set up the following equation:
2.5x = 360
Solving for x, we get:
x = 144
0.25x = 0.25*144
