Answer: IQR=32

Step-by-step explanation:IQR=Q3-Q1

The 2x²- 4, expression is equivalent to 2(x²-2) with the same variable and exponent we multiply with their constant value.

Distribution property: Multiplying numbers by the sum or difference is the same as multiplying each number in the sum or difference and then adding or subtracting. Example: 6(2+4)= 6(2) + 6(4)

Equivalent Expressions: Expressions are equivalent if they are equal to each other when contracted or expanded. Steps to write equivalent expression using distributive Property,

Step 1 : A list of all the elements with coefficient a

Step 2: List all the factors of constant b.

Step 3: Compare the factors identified in a and b and identify the factors they have in common.

Step 4: Choose one of the factors f such that f(ax/f + b/f). We have, f(x) = 2x² - 4 . Using the above steps,

=> 2x² - 4 = 2 × x × x - 2× 2

As we see, 2 is common factor in both

=> 2( x² - 2)

So, required expression is 2( x² - 2) .

What is the equivalent of 2x² - 4?.

Answer:

On a logarithmic scale, numbers on the Y-axis don't move up in equal increments but instead each interval increases by a set factor – it's often 10 but could be a factor of 3 or 350 or 3,500, anything at all.

Step-by-step explanation:

The scale factor for the triangle is 8 : 1.

The first option is the correct option.

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).

Given:

A triangle with a perimeter of 24 meters was created from a triangle,

with a perimeter of 3 meters using a scale factor.

Then the scale factor,

= Actual triangle / scale triangle

= 24 / 3

= 8/1

The amount of money that each team raised are;

Amount raised by Back Street location = $200

Amount raised by Main Street location = $250

Amount raised by Washington Street = $150

We are told that the main street location raised $50 more than the Back Street location. Thus;

m.s = b.s + 50    ------(eq 1)

The Washington Street location raised $50 more than half the amount raised at the Back Street location. Thus;

w.s = ¹/₂b.s + 50    -------(eq 2)

Total raised = $600. Thus;

m.s + b.s + ws = 600    -------(eq 3)

-----------------------------

Plug in b.s + 50 for m.s and ¹/₂b.s + 50 for w.s in eq 3 to get;

(b.s + 50) + (¹/₂b.s + 50) + b.s = 600

Solve for b.s;

b.s + ¹/₂b.s + b.s + 50 + 50 = 600

(5/2)b.s + 100 = 600

(5/2)b.s = 500

b.s = $200 (amount raised by Back Street location)

m.s = b.s + 50

= 200 + 50

= $250 (amount raised by Main Street location)

w.s = (1/2)b.s + 50

w.s = 100 + 50

w.s = $150 (amount raised by Washington Street)

The formula of quadratic function at vertex form is  f(x) = a(x – h)² + k

The term vertex in math is referred as a point where two or more curved lines or edges meet.

Here as a consequence of this definition we know that the point where two lines meet to form an angle and the corners of polygons and polyhedral are vertices.

Here we need to identify the formula of quadratic function at vertex form

As we all know that If a parabola opens upward, then it has a lowest point.

Where as If a parabola opens downward, then it has a highest point.

Here this lowest or highest point is the vertex of the parabola.

Here we have take the parent function f(x) = x² has its vertex at the origin.

And now you can identify the vertex of other quadratic functions by analyzing the function in vertex form.

So, the vertex form of a quadratic function is written as

=> f(x) = a(x – h)² + k

Here a, h, and k are constants.

Answer:

700 meters.

Step-by-step explanation:

The actual distance between the two points can be determined by using the scale of the map. If the scale of the map is 1:10,000, it means that one unit of measurement on the map represents 10,000 units of the same measurement in reality.

Therefore, if the distance between the two points on the map is 7cm, the actual distance is 7cm * 10,000 = 70,000cm or 700 meters.

So, the actual distance between the two points is 700 meters.

Percentage of unemployment is 58.33 % in the total household of 60,000.

Although the abbreviations "pct.", "pct.", and "pct." are also used, the percent symbol, "%," is most commonly used. A percentage is a number with no dimensions and no standard measurement.

The English word "percentage" is derived from the Latin phrase "per centum," which means "by the hundred." Percentages are fractions with a numerator of 100. In other words, it is a relationship in which the total value is always assumed to be one hundred.

Percentage calculation is the process of determining a percentage of a whole in terms of 100. There are two ways to calculate a percentage:

Using the unitary approach

by adjusting fraction's denominator to 100.

It should be noted that when the denominator is not a factor of 100, the second technique of percentage calculation isn't applied. In these situations, we employ the unitary technique.

Total number of household is 60000

Total number of household which is unemployed is 35000

Percentage of unemployment = (35000/60000) * 100 = 58.33 %

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

Let x be the number of windows Savannah cleans.

The amount of window cleaner Savannah uses can be represented by the equation:

3.5x = oz

To represent the inequality that Savannah uses more than 18 windows, we can write:

x > 18

This inequality states that the number of windows Savannah cleans (x) is greater than 18.

Combining both the equation and the inequality we can write

3.5x > 63 oz

A reasonable prediction for the number of times a green or red bead will be drawn from the container of beads, after being replaced 60 times, would be 42.

A reasonable prediction for the number of times a green or red bead will be drawn from the container of beads, after being replaced 60 times, would be close to the proportion of green or red beads in the container. The container has 8 red beads and 6 green beads out of a total of 8 + 7 + 6 = 21 beads. The proportion of green or red beads is (8 + 6) / 21 = 14/21.

We can use this proportion to predict the number of times a green or red bead will be drawn from the container. By multiplying the proportion of green or red beads by the number of times the bead is replaced, we get (14/21) * 60 = 42.

In this scenario, we are using the concept of probability and proportion. The probability of drawing a green or red bead is 14/21, and by multiplying it by the number of trials (60), we get the expected number of times the green or red bead will be drawn. This concept is used in statistics and probability to make predictions based on the available data. It is important to note that this is only a prediction and actual results may vary.

The value of 'x' = 12°

A circle is a closed polygon and a two-dimensional object where every point in the plane is equally spaced from a central point. Examples are rings, discs, wheels, bangles, coins, etc.

In a circle angle at the center will always equal 360°. There is a number of circular items that we can observe in the real world.

Here we have

(x²)°, 10x°, and (5x+36)° angles made by 3 sectors in a circle

As we know the sum of the angles at the center of a circle = 360°

=> x² + 10x + 5x+36  = 360  

=> x² + 15x  +36 = 360  

=>  x² + 15x - 324 = 0

Now factorize the above equation for the 'x' value

=> x² + 27x - 12x - 324 = 0  

=> x(x + 27) - 12(x + 27) = 0

=> (x + 27) (x - 12) = 0  

=> (x + 27) = 0     or     (x - 12) = 0             144 + 96
