Answer:

42.6%

Step-by-step explanation:

The percent increase is calculated as

percent increase = \(\frac{increase}{original}\) × 100%

increase = $3.55 - $2.49 = $1.06

% increase = \(\frac{1.06}{2.49}\) × 100% ≈ 42.6% (to the nearest tenth )

The product of the two matrices Q₁Q₂ is orthogonal

In linear algebra, an orthogonal matrix, or orthonormal matrix, is a real square matrix whose columns and rows are orthonormal vectors. ... {\displaystyle Q^{\mathrm {T} }Q=QQ^{\mathrm {T} }=I,} where QT is the transpose of Q and I is the identity matrix.

It is said to be an orthogonal matrix if its transpose is equal to its inverse matrix, or when the product of a square matrix and its transpose gives an identity matrix of the same order.

If A is an n*n orthogonal matric, then A*A¹ = A¹*A

Therefore A*A¹ = A¹*A  = 1

This implies that the product Q₁O₂ is orthogonal.

Answer:

This is very simple . you can easily understand. hope it helps.

Answer:

m = 4

Step-by-step explanation:

We have similar trapezoids, so corresponding angles must be congruent, and the ratios of pairs of corresponding sides must be equal. For both of these to be true, we need to find the ratio of pairs of corresponding sides:

13 / 5.2 = 2.5, 12 / 4.8 = 2.5, 22.5/9 = 2.5,

15 / 6 = 2.5

So

\( \frac{10}{m} = 2.5\)

If the average of x and y is 11 and the average of x, y and z is 5, then the value of z is -7

Given,

The average of x and y = 11

We know average = Sum of the terms / Number of terms

Then, the equation will become

\(\frac{x+y}{2}=11\)
x+y =11×2

x+y =22

Average of x, y and z = 5

\(\frac{x+y+z}{3}=5\)

x+y+z = 5×3

x+y+z =15

Substitute the value of x+y

22+z=15

z =15-22

x = -7

Hence, If the average of x and y is 11 and the average of x, y and z is 5, then the value of z is -7

As the Percentage decreased, The Number of alligators in 2001 = 438972

What is the Percentage decrease?

A variable's value loss can be measured using the percentage decline formula. The variable might be anything from profit to population to cost. For a better understanding of the idea, the formula for percentage drop is provided below along with solved instances.

∴ Percent Decrease = (Decreased Value / Original Value) × 100

Number of alligators in 1992 = 285

Percentage of increase every year = 75%

Every year 75 increased per 100

2001 - 1992 = 9 years

Step: 3

So the population in 2001, as the percentage decreased, is:

\(\begin{aligned}&=285 \times\left(\frac{175}{100}\right)^9 \\&=285 \times\left(\frac{7}{4}\right)^9\end{aligned}\)

= 43871.986

Number of alligators in 2001 = 438972

Hence, The Number of alligators in 2001 = 438972

156.52 - x = 56.29

just flip x with 56.29

156.52 - 56.29 = x

x = 100.23

Answer: 212.81

Step-by-step explanation: You would, in this case, carry the 156.52 across the equal sign and then swap out the subtraction sign with an addition sign. You would then flip the equation around so it would like this: 156.52+56.29=??. All you would have to do now, is add the numbers and you have you answer. Good luck on your test!

Correction: Keep the subtraction sign and then you should get your answer.

Answer:

$261.80 Net pay

Step-by-step explanation:

340 x 0.23 =   $78.20 in taxes

$340 - $78.20 =  $261.80 Net pay

Answer:

$261.8 Is how much you take home.

Step-by-step explanation:

(* is multiply)

In order to find the percentage of a value, you multiply the value by the percent. Think of 100% as a scale of 1 to 0.00, since 100% of something has all of it's value, so 50% would be 0.5

23% of 340 is 78.2 ( 340 * 0.23)

Subtract 340 by 78.2, and you get your net pay, 261.8

Another way to do this is subtract 100% by 23%.

so 1 - 0.23= 0.77, which is how much percent of that pay you get to keep

so 340 * 0.77 = 261.8

The error in finding the measure of one exterior angle of a regular polygon lies in using the formula 360°/n, where n is the number of sides of the polygon.

The formula 360°/n is used to find the measure of each exterior angle of a regular polygon. It is based on the idea that the sum of all exterior angles of any polygon is always 360 degrees. However, this formula assumes that the polygon has internal angles of 180°, which is true only for regular polygons.

The error occurs when this formula is applied to a non-regular polygon, as non-regular polygons have varying internal angles. Using the formula 360°/n for a non-regular polygon will give incorrect results because the internal angles are not all equal.

For regular polygons, each exterior angle is indeed 360°/n, and the sum of all exterior angles will be 360 degrees. However, for non-regular polygons, this formula cannot be used, and the measures of exterior angles must be calculated differently based on their internal angles and sides.

The error in finding the measure of one exterior angle of a regular polygon is they divided 360 by 10 instead of 5.

Given that,

There are a total of 10 exterior angles, two at each vertex, so the measure of one exterior angle is 360°/10 = 36°.

Here, at each vertex there are two angles.

So, there must be 5 vertices and 5 sides.

Then, the measure of one exterior angle = 360°/5

= 72°

The dimensions of a rectangular prism are length, width, and depth.

Volume = length * width * depth

Here, V = 3y3 + 16y2 + 5y. If you can factor that into three terms, those could be the dimensions of the prism.

How do you factor it? Do all three terms have something in common? Sure, they all have a y, so factor a y out of each term.

V = y(3y2 + 16y + 5)

Then, factor what's left.

V = y(3y + 1)(y + 5)

The dimensions of the prism are y, (3y + 1), and (y + 5).

Answer: The product of (abc) is (-2/3)(1/3)(-1) = 2/9.

Answer:

(0,1) is not the solution to the equation

Step-by-step explanation:

Given:

−3x − 8y = −8 (1)

y = 2 − x ​ (2)

Substitute (2) into (1)

−3x − 8y = −8 (1)

- 3x - 8(2 - x) = -8

- 3x - 16 + 8x = -8

- 3x + 8x = -8 + 16

5x = 8

x = 8/5

Substitute x = 8/5 into (2)

y = 2 − x ​ (2)

= 2 - 8/5

= (10-8) / 5

= 2/5

y = 2/5

Solution to the equation:

(x, y) = (8/5, 2/5)

Therefore,

(0,1) is not the solution to the equation

If the CI includes the value 1, we cannot reject the null hypothesis

If we are testing the null hypothesis H0: σ1² = σ2² against the alternative hypothesis H1: σ1² ≠ σ2² and we develop a 1-α percent confidence interval (CI) on σ1²/σ2², the number that would be in the CI if we failed to reject H0 would be 1.

This is because, under the null hypothesis, the ratio of the variances σ1²/σ2² equals 1 (since σ1² = σ2²).

So, if the CI includes the value 1, we cannot reject the null hypothesis.

the solution to the system of equations is x = 2 and y = 1.

To solve the system of equations by substitution, we will solve one equation for one variable and substitute it into the other equation.

Given the system of equations:

1) y = 6x - 11

2) -2x - 3y = -7

Step 1: Solve equation (1) for y.

  y = 6x - 11

Step 2: Substitute the value of y from equation (1) into equation (2).

  -2x - 3(6x - 11) = -7

Step 3: Simplify and solve for x.

  -2x - 18x + 33 = -7

  -20x + 33 = -7

  -20x = -7 - 33

  -20x = -40

  x = (-40)/(-20)

  x = 2

Step 4: Substitute the value of x into equation (1) to find y.

  y = 6(2) - 11

  y = 12 - 11

  y = 1

Therefore, the solution to the system of equations is x = 2 and y = 1.

The solution to the system of equations y = 6x - 11 and -2x - 3y = -7 is x = 2 and y = 1. This is achieved by substituting y into the second equation, simplifying, and solving for x, then substituting x back into the first equation to solve for y.

To solve the system of equations y = 6x - 11 and -2x - 3y = -7 by substitution, we start by substituting the equation y = 6x - 11 into the second equation in place of y, giving us -2x - 3(6x - 11) = -7. Next, simplify the equation by distributing the -3 inside the parentheses to get -2x - 18x + 33 = -7. Combine like terms to get -20x + 33 = -7. Subtract 33 from both sides to obtain -20x = -40, and finally, divide by -20 to find x = 2.

Once we find the solution for x, we substitute it back into the first equation y = 6x - 11. Substituting 2 in place of x gives y = 6*2 - 11, which simplifies to y = 1.

Therefore, the solution to the system of equations is x = 2 and y = 1.
