Answer:i think its 115 degres

Step-by-step explanation:

No, there is no commutative property of subtraction for rational numbers. The commutative property, which states that the order of operands does not affect the result of an operation, does not apply to subtraction for rational numbers.

The commutative property states that the order of the operands does not affect the result of an operation. For addition and multiplication, the commutative property holds true. However, for subtraction, the order of the operands does matter, and thus, the commutative property does not apply.

Let's consider an example to demonstrate this:

Take the rational numbers 3/4 and 1/2.

If we subtract 3/4 from 1/2, we have: 1/2 - 3/4 = (2/4) - (3/4)

= -1/4.

If we subtract 1/2 from 3/4, we have: 3/4 - 1/2 = (3/4) - (2/4)

= 1/4.

As you can see, the results are different when the order of subtraction is changed, indicating that subtraction does not follow the commutative property for rational numbers.

The commutative property, which states that the order of operands does not affect the result of an operation, does not apply to subtraction for rational numbers. Changing the order of subtraction changes the result, making subtraction non-commutative for rational numbers.

The commutative property does not apply to the operation of subtraction with rational numbers. This is because changing the order of the numbers in a subtraction operation will give a different result.

In mathematics, the commutative property refers to the idea that the order in which numbers are used in an operation does not change the result of that operation. This property holds true for addition and multiplication but, unfortunately, it does not hold true for subtraction and division. For example, in subtraction, if we take two rational numbers such as 5 and 3, 5 - 3 is equal to 2, but 3 - 5 equals to -2. As you can see, changing the order of the numbers gives us different results, demonstrating that there is no commutative property of subtraction for rational numbers.

The total amount of revenue generated by the store's CD sales on April 18 is 21,144.2.

To find the total amount of revenue generated by the store's CD sales on April 18, we need to calculate the product of the number of CDs sold and the price per CD on that day.

First, let's find the number of CDs sold on April 18. We are given the function n(d) = 12d + 35, where d represents the number of days since April 8. Since we want to find the number of CDs sold on April 18, we substitute d = 18 into the function:

n(18) = 12(18) + 35
n(18) = 216 + 35
n(18) = 251

So, the store sold 251 CDs on April 18.

Next, we need to find the price per CD on April 18. We are given the function p(d) = 0.3d^2 - d + 5. Substituting d = 18 into the function:

p(18) = \(0.3(18)^2 - 18 + 5\)
p(18) = 0.3(324) - 18 + 5
p(18) = 97.2 - 18 + 5
p(18) = 84.2

So, the price per CD on April 18 is $84.2.

To find the total amount of revenue generated, we multiply the number of CDs sold by the price per CD:

Revenue = Number of CDs sold * Price per CD
Revenue = 251 * 84.2

Calculating this product, we find that the total amount of revenue generated by the store's CD sales on April 18 is 21,144.2.

In conclusion, the total amount of revenue generated by the store's CD sales on April 18 is 21,144.2.

Answer:

C. 159.0 square inches

Step-by-step explanation:

Given that

Ted ate 3 pieces of the pizza

We need to find out the area of the remaining pizza in the case when the pizza diameter is 18 inches

Since the large circular pizza is divided into 8 equal slices

Now the radius of a pizza is

= 18 ÷ 2

= 9 inches

Now the angle subtended by each pizza is

= 360 degrees ÷ 9 inches

= 45 degrees

Now the area of the each pizza is

= \(\theta\) ÷ 360 × πr^2

= 45 ÷ 360 × 3.14 × 9^2

= 31.7925

Now the area of the remaining pizza is

= 5 × 31.7925

= 158.9625

= 159 square inches

Step-by-step explanation:

B is asking how many years until you are 16; this is not statistical because it just a fact. F is pretty much the same because it's just asking a subjective fact-like question.

Statistical questions ask for a collection of varying data. If there is only one data point, it is non-statistical.

This exercise has nothing to do with inverse operations.

Let L represent the number of lawns Tyler mows, and D the number of dogs he walks.

If he earns $20 for each lawn mown, then mowing L lawns earns him $20L. For example, if he mows 1 lawn, he gets $20. If he mows 2 lawns, he earns $40. And so on.

The same could be said about dog-walking. If he earns $15 for each walk, then walking D dogs is worth $15D. For example, if he walks 1 dog, he gets $15; for 2 dogs, $30; and so on.

If after a week he has earned a total of $260, then

20L + 15D = 260

which can optionally be simplified a bit by dividing through both sides by 5 to get

4L + 3D = 52

Since you mentioned "inverse", I suspect you interpreted the question as asking how many lawns Tyler mowed and how many dogs he walked. This is impossible, you cannot determine exactly how many lawns or dogs were involved. But there are only 4 ways this can happen, since L and D must be counting numbers.

D = 4, L = 10

D = 8, L = 7

D = 12, L = 4

D = 16, L = 1

the larger of the two acute angles of the right triangle is π radians or 180 degrees.

Let's begin by using the identity cos(θ) = sin (π/2 - θ) to write:

cos(8x) = sin (4x + 3) = sin (π/2 - (4x + 3))

We can simplify sin (π/2 - (4x + 3)) using the identity sin (π/2 - θ) = cos(θ), so we have:

cos(8x) = cos (4x + 3)

Now we can use the identity cos(θ) = cos(-θ) to write:

cos(8x) = cos (-4x - 3)

This means that either 8x = -4x - 3 + 2πn or 8x = 4x + 3 + 2πn for some integer n.

Solving the first equation, we get:

12x = 2πn - 3

x = (2πn - 3)/12

Solving the second equation, we get:

4x = 2πn - 3

x = (2πn - 3)/4

We want to find the larger of the two acute angles of the right triangle, which is the angle opposite the longer leg. Let's call this angle A. We know that:

\(cos(A) = adjacent/hypotenuse\)

\(sin(A) = opposite/hypotenuse\)

We can use the Pythagorean theorem to relate the sides of the triangle:

\(opposite^2 + adjacent^2 = hypotenuse^2\)

Let's set up the equations for the two possible values of x:

For x = (2πn - 3)/12:

cos(8x) = cos (2πn - 3 - 2πm) = cos (3 - 2πm) = cos (2πm - 3)

cos (4x + 3) = cos (2πn + 3π/2) = 0

So, we have:

cos(A) = cos (2πm - 3)

sin(A) = 0

\(opposite^2 + adjacent^2 = hypotenuse^2\)

This means that either A = 0 or A = π. However, A cannot be 0 because that would make the triangle degenerate. Therefore, A = π.

For x = (2πn - 3)/4:

cos(8x) = cos (2πn - 3 - 2πm) = cos (3 - 2πm) = cos (2πm - 3)

cos (4x + 3) = sin (2πn + 3π/2) = -1

So, we have:

cos(A) = cos (2πm - 3)

sin(A) = -1/hypotenuse

\(opposite^2 + adjacent^2 = hypotenuse^2\)

From the equation sin(A) = -1/hypotenuse, we can see that A is the angle opposite a side with length -1, which is impossible. Therefore, there are no solutions for this case.

In summary, the larger of the two acute angles of the right triangle is π radians or 180 degrees.

The profit of Aslam is Rs. 31,474.50 and the profit of Akram is Rs. 35,025.50.

To find the profit of each person, we can use the concept of ratios.

First, let's find the total investment made by both Aslam and Akram:
Total investment = Aslam's investment + Akram's investment
Total investment = 27000 + 30000 = 57000

Next, let's calculate the ratio of Aslam's investment to the total investment:
Aslam's ratio = Aslam's investment / Total investment
Aslam's ratio = 27000 / 57000 = 0.4737

Similarly, let's calculate the ratio of Akram's investment to the total investment:
Akram's ratio = Akram's investment / Total investment
Akram's ratio = 30000 / 57000 = 0.5263

Now, we can find the profit of each person using their respective ratios:
Profit of Aslam = Aslam's ratio * Total profit
Profit of Aslam = 0.4737 * 66500 = 31474.5

Profit of Akram = Akram's ratio * Total profit
Profit of Akram = 0.5263 * 66500 = 35025.5

Therefore, the profit of Aslam is Rs. 31,474.50 and the profit of Akram is Rs. 35,025.50.

The area of the triangle whose vertices are (-3, 5), (3, -6), and (7, 2) is 14.

To find the area of a triangle given the coordinates of its vertices, we can use the formula:

Area = 1/2 * |(x1y2 + x2y3 + x3y1) - (y1x2 + y2x3 + y3x1)|

where (x1,y1), (x2,y2), and (x3,y3) are the coordinates of the three vertices.

Substituting the given coordinates, we get:

Area = 1/2 * |(-3*-6 + 32 + 75) - (5*3 - (-6)7 + 2(-3))|

= 1/2 * |(-18 + 6 + 35) - (15 + 42 - 6)|

= 1/2 * |23 - 51|

= 1/2 * |-28|

= 14

The statement is false. The repeated-measures ANOVA is more likely to detect a treatment effect compared to the independent-measures ANOVA due to its ability to control for individual differences. By measuring the same subjects under different conditions, the repeated-measures design reduces the influence of individual variability and increases the sensitivity to detect treatment effects.

Bootstrap analysis is a statistical method used to determine the reliability and robustness of phylogenetic trees' topologies. In bootstrap analysis, a series of random resampling with replacement is used to assess how well the observed data fit the phylogenetic hypothesis.

Bootstrap values range from 0 to 100 and reflect the proportion of times that a particular node or branch occurs in the bootstrap replicate trees. Bootstrap values greater than 70% are usually considered strong evidence that a particular node or branch exists in the phylogenetic tree.
