Answer:

Pentagon and an OCTAGON

Step-by-step explanation:

Polygons are are plane figures with three or more sides. Since plane figures with 3sides are triangles and those with 4sides are quadrilaterals, I will take a plane figure of 5sides as one of the two polygons Ellen is drawing

A plane figure with 5sides and 5angles is a PENTAGON

If one of the polygons has 3 more angles than the other, then the other polygon she is drawing was a polygon with (5+3) i.e 8sides and 8angles. This polygon is known as an OCTAGON

Based on the conclusion, the shape Ellen could be drawing is a PENTAGON and an OCTAGON

Answer:

The correct option is 1. It means 11x is the area cut from the sheet of wrapping paper.

Step-by-step explanation:

The shape of sheet is square.

Let  x represents the length, in centimeters, of the sheet of wrapping paper before being cut.

The area of a square is

[tex]A=a\times a[/tex]

Where, a is side length.

The area of sheet before being cut is

[tex]A=x\times x=x^2[/tex]

The width of the piece cut from the sheet is 11 and length is x. So, the area of piece is

[tex]A=x\times 11=11x[/tex]

The remaining area of sheet is

[tex]A=\text{Area of sheet}-\text{Area of piece cut from the sheet}[/tex]

[tex]A=x^2-11x[/tex]

Therefore correct option is 1. It means 11x is the area cut from the sheet of wrapping paper.

Caleb is 11 years old, Baz is 22 years old, and Judi is 31 years old, which adds up to 64 years in total.

If Caleb's age is C, then Baz, being twice as old, is 2C. Judi is 9 years older than Baz, so her age is 2C + 9.

C + 2C + 2C + 9 = 64

5C + 9 = 64

Subtracting 9 from both sides gives:

5C = 55

C= 11

The probability that both selected boxes have the secret decoder ring is approximately 7.20%

To find the probability that both selected boxes have the secret decoder ring, we can use the concept of independent events. Since the boxes are randomly selected, the probability of selecting a box with the secret decoder ring is 13/47 for the first box. After selecting the first box, there will be 12 boxes with the secret decoder ring left out of 46 total boxes. So, the probability of selecting a second box with the secret decoder ring is 12/46. To find the probability of both events occurring, we multiply the probabilities: (13/47) * (12/46) = 156/2162 ≈ 0.07197 or about 7.20%

part A

the x intercept 0 is the point where the ball was hit, the x intercept 20 is the point where the ball fell back to the ground, 20 feet away from the kicker.

the function is increasing in the interval x∈(0, 10) and decreasing in x∈(10, 20) 
this means that the height is increasing in the interval  (0, 10) and decreasing as x goes through the interval (10,20)
the distance from the kicker is increasing during the whole interval (0, 20)

If two sets are negatively correlated, as the values in one of the sets increase, the values in the other set tend to decrease.

For a message to be processed by a certain orchestration, a correlation set specifies a collection of qualities and values for these properties. A maximum of three parameters are supported by each correlation set.

If two sets are negatively correlated, as the values in one of the sets increase, the values in the other set tend to decrease.

This means that there is an inverse relationship between the two sets, such that when one variable increases, the other variable tends to decrease.

This type of correlation is often expressed by a negative correlation coefficient,

which ranges from -1 to 0, with -1 indicating a perfect negative correlation.

Final answer:

We use reverse operations to solve Joseph's equation and find that the original number could have been either 8 or -8.

Explanation:

The question asks us to determine Joseph's original number based on a series of mathematical operations. We can set up an equation to represent the problem statement: let x be the original number. The sequence of operations given is:

Square x and subtract 8.

Divide this result by 7.

Add 12 to the result from step 2.

The final result is 20.

Representing this mathematically: ((x2 - 8) / 7) + 12 = 20. To find x, we need to work backward through these operations:

Subtract 12 from both sides: ((x2 - 8) / 7) = 8.

Multiply both sides by 7: x2 - 8 = 56.

Add 8 to both sides: x2 = 64.

Take the square root of both sides: x = 8 or x = -8 (considering both positive and negative square roots).

Therefore, Joseph's original number could have been either 8 or -8.

The y-intercept is the point where the line cuts the y-axis, hence the y-intercept is (0,3)

The formula for calculating slope of a line is expressed as:

Slope = y2-y1/x2-x1

Using the coordinate points (0, 3) and (4, 0)

Slope = 0-3/4-0
Slope = -3/4

Since the y-intercept is the point where the line cuts the y-axis, hence the y-intercept is (0,3)

see picture

Circle can be defined as a set of all points in a plane that are the same distance from a fixed point called the center.

A circle has defined the set of all points in a plane that are the same distance from a fixed point called the center. The circle is a 2D shape.

In geometry, the circle is defined as the closed 2-dimensional curved shape. The distance from between the center of the circle to any point on the circle is known as the radius of the circle.

As we have discussed the definition of a circle, therefore, the correct option is 'A circle is the set of all points in a plane that are the same distance from a fixed point called the center.'
