John's purchasing power increased by 0.97%.

What is the inflation?

The definition of inflation in the field of economics is "mean increased money supply, but the general public often refer to a sustained increase in the general price level of goods and services in an economy over a period".

If the inflation rate was 3% and John's salary grew 4%, his salary increased more than the rate of inflation. However, his real increase in purchasing power depends on the difference between his salary growth rate and the inflation rate.

To calculate the change in John's purchasing power, we can use the following formula:

Change in purchasing power = (1 + Salary growth rate) / (1 + Inflation rate) - 1

Plugging in the values, we get:

Change in purchasing power = (1 + 0.04) / (1 + 0.03) - 1

Change in purchasing power = 1.01 / 1.03 - 1

Change in purchasing power = 0.0097 or 0.97%

Hence, John's purchasing power increased by 0.97%.

The scale factor of the preimage to the image is 5/2

The length of BC is 10 units

The scale factor is the size by which the shape is enlarged or reduced. It is used to increase the size of shapes like circles, triangles, squares, rectangles, etc.

The scale factor of the preimage to the image can be found by finding the ratio of the corresponding sides of the preimage to the image. That is:

scale factor = DC / D'C'

scale factor = 5/2

Also, the scale factor = BC / B'C' and the scale factor is constant (i.e. 5/2)

scale factor = BC / B'C'

5/2 = BC/4

BC = 5/2 * 4

Therefore, one container can hold 20/9 tons of sugar.

To simplify this expression, we can convert the mixed number 3 3/5 to an improper fraction:

3 3/5 = (5*3 + 3)/5 = 18/5

So the expression becomes:

8 tons / (18/5) containers

To divide by a fraction, we can multiply by its reciprocal:

8 tons / (18/5) containers = 8 tons * (5/18) containers

Now we can simplify the expression and solve for the amount of sugar in one container:

The new average salary of the people on the bus is $84,44,96,111.11  and the median salary will not change and will remain same.

Given, we know that average salary of the 9 people on the bus is $65,000.

Formula for Average = sum of salary of all people/ the number of people.

Let us say average salary of first 8 people is 'S'. Given, salary of the 9th guy on the bus is $120,000 Now, we can write it like this :

⇒$65,000  = (S + $120,000)/9

⇒585,000 = S + $120,000

⇒S = $465,000

Therefore, average salary of 8 people is $465,000 after the 9th guy gets off. Now Bill Gates enters the bus with a salary of $7,600,000,000. New average salary :

⇒ (S + $7,600,000,000) / 9

⇒$84,44,96,111.11

Median will not change since, The median of a set of numbers is the number in the middle when you list them in order. For example, the median of {1, 3, 6, 9, 13} is 6. If you replace the highest number with a different number, the median will not change. In this example, {1, 3, 6, 9, 100} still has a median of 6.

Therefore, the new average yearly income of the people on the bus along with Bill Gates is $84,44,96,111.1111.

Answer:

I think the system has infinite solutions.

Step-by-step explanation:

David has drawn a total of 177 cm of lines.

We can use the Pythagorean theorem, which tells us that in a right triangle, the square of the length of the hypotenuse (the diagonal line) is equal to the sum of the squares of the lengths of the other two sides (the lines along the long edge and the width).

In this case, the length of the hypotenuse is the distance from the starting corner to the end of the diagonal line, which we can calculate as follows:

d = √(77² + 36²) ≈ 85.99 cm

Therefore, David has drawn a total of 77 cm + 36 cm + 85.99 cm = 198.99 cm of lines. However, we should subtract the length of the starting corner to the end of the first line, which is 77 cm, since it was counted twice (once as part of the diagonal line and once as part of the line along the long edge).

So, the total length of lines that David has drawn is 77 cm + 36 cm + 85.99 cm - 77 cm = 177 cm.

Pythagoras' theorem is a fundamental theorem in mathematics that relates to the sides of a right triangle. It states that in any right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

This can be expressed as:

a² + b² = c²

where a and b are the lengths of the two legs of the right triangle, and c is the length of the hypotenuse.

Pythagoras' theorem can be used to solve a variety of problems involving right triangles, such as finding the length of a missing side or determining whether a triangle is a right triangle. It is also the basis for the distance formula in two and three-dimensional Euclidean space.

Pythagoras' theorem has applications in many fields, including physics, engineering, and computer graphics, and it is one of the most important and widely used theorems in mathematics.

We enter x=0 into the equation to obtain the y-intercept:

[tex]y = (x + 2)^2 - 4[/tex]

[tex]y = (0 + 2)^2 - 4[/tex]

y = 4 - 4

y = 0

The correct option is A: A linear pair is two adjacent, supplementary angles.

Supplementary angles are a pair of angles whose measures add up to 180 degrees. In other words, if we place two angles side by side, and their measures add up to 180 degrees, then they are said to be supplementary.

For example, if we have an angle with a measure of 120 degrees, then its supplementary angle would have a measure of 60 degrees, since 120 + 60 = 180. It's important to note that the two angles in a pair of supplementary angles do not have to be adjacent, meaning they can be located anywhere in a figure, as long as their measures add up to 180 degrees.

Supplementary angles play an important role in geometry and mathematics, especially when it comes to solving problems involving angles. For instance, if we know that two angles are supplementary, and we know the measure of one of the angles, we can easily calculate the measure of the other angle by subtracting the known measure from 180 degrees.

In addition, supplementary angles are often used in real-life situations, such as when designing buildings, bridges, or other structures that require precise measurements of angles.

arr = np.array([[1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12]])

# get the number of columns in the array

num_cols = arr.shape[1]

# create a list of column indices

col_indices = np.arange(num_cols)

# shuffle the column indices randomly

shuffled_col_indices = np.random.permutation(col_indices)
