The labels on the x-axis indicate the type of card, and the percentages are listed on the y-axis.

Algebraic expression can be defined as combination of variables and constants.

To create a percent bar graph for the cards in the deck, we first need to determine the percentage of each type of card in the deck.

There are a total of 25 cards in the deck, and the breakdown of each type of card is as follows:

4 cards labeled with a "": (4/25) x 100% = 16%

6 cards labeled with a "": (6/25) x 100% = 24%

10 cards labeled with a "": (10/25) x 100% = 40%

5 cards labeled with a "": (5/25) x 100% = 20%

Now that we have the percentage for each type of card, we can create the percent bar graph.

Cards Label    

"" 16%  

""  24%  

""   40%

""    20%

In this graph, each bar represents a type of card in the deck, and the length of each bar represents the percentage of cards that fall into that category.

Therefore, The labels on the x-axis indicate the type of card, and the percentages are listed on the y-axis.

Answer:

1/4 x 4/1 x4/1= 2

6/1 x 6/1 x1/6=2

Step-by-step explanation:

The required probability that the mean height of a sample of sixteen men falls between 66 and 68 inches is approximately 0.6827.

We know that the sample size n = 16, the population mean μ = 67 inches, and the population standard deviation σ = 4 inches.

The sampling distribution of the sample mean can be approximated by a normal distribution with mean μ and standard deviation σ/√n.

Thus, the distribution of the sample mean can be expressed as:

[tex]$\bar{X} \sim \mathcal{N}(\mu, \frac{\sigma}{\sqrt{n}})$$[/tex]

Substituting the given values, we have:

[tex]$\bar{X} \sim \mathcal{N}(67, \frac{4}{\sqrt{16}})$$[/tex]

[tex]$\bar{X} \sim \mathcal{N}(67, 1)$$[/tex]

To find the probability that the sample mean falls between 66 and 68 inches, we need to find the z-scores corresponding to these values and calculate the area under the normal curve between these z-scores.

The z-score corresponding to a sample mean of 66 inches is:

[tex]$z = \frac{66 - 67}{1} = -1$$[/tex]

The z-score corresponding to a sample mean of 68 inches is:

[tex]$z = \frac{68 - 67}{1} = 1$$[/tex]

Thus, we need to find the probability that the z-score falls between -1 and 1. Using a standard normal distribution table or calculator, we can find that this probability is approximately 0.6827.

Therefore, the probability that the mean height of a sample of sixteen men falls between 66 and 68 inches is approximately 0.6827.

We are asked to find the measure of ∠CEB.

We already know that the 3 angles combined have a total sum of 163°.

Let's set the 3 angles equal to 163°.

[tex]x-10+4x +2x+5=163[/tex]

Now, we should Combine Like Terms.

Combining Like Terms is adding, or subtracting together 2 or more numbers or variables that are alike.

For example, if we were given the expression;

[tex]5x + 3 - 2x + 9[/tex]

We should combine 5x and 2x, 3 and 9 since they are like terms.

For our equation;

[tex]x-10+4x +2x+5=163[/tex]

We should combine x, 4x, and 2x. We also should combine -10, 5, and 163.

The area of the model on the right is 6.25 square centimeters.

What is area ?

Area is a measurement of the size of a two-dimensional surface or region. It is the amount of space inside a closed figure or shape, and is typically measured in square units such as square meters, square feet, or square centimeters.

Since the two models represent the same rectangular patio, they must have the same area.

Let A be the area of the model on the right in square centimeters.

Using the ratios given in the problem, we can write:

A/4 = (1.25 ft/1 cm)²

Simplifying the right-hand side, we get:

A/4 = 1.5625 ft²/cm²

Part D: the absolute value of -1.8 is the same as the absolute value of 1.8, we have shown that you hiked the same distance in both directions.

It can be measured in various units such as meters, kilometers, feet, miles, etc. In mathematics, the distance between two points in a coordinate plane can be calculated using the distance formula, which is derived from the Pythagorean theorem. The distance formula is:

d = √[(x2 - x1)² + (y2 - y1)²]

Where (x1, y1) and (x2, y2) are the coordinates of the two points and d is the distance between them

Part A: The distance from the top of the waterfall to the place where you eat lunch is 1.3 miles, so the drone would need to fly up 1.3 miles

Part B: The distance from the top of the waterfall to the place where you go swimming is 1.8 miles, so the drone would need to fly up 1.8 miles

Part C: In this problem, the value of zero represents the top of the waterfall where you and your friend are currently located.

Part D: Let x be the distance you hiked to go swimming, and let y be the distance you hiked to go back to the top to meet your friend. Then, the total distance you hiked is the sum of the absolute values of x and y, which can be written as |x| + |y|. Since you hiked down 1.8 miles to go swimming and then hiked back up 1.8 miles to the top, x = -1.8 and y = 1.8. Substituting these values, we get |(-1.8)| + |1.8| = 1.8 + 1.8 = 3.6. Since the absolute value of -1.8 is the same as the absolute value of 1.8, we have shown that you hiked the same distance in both directions.

So the area of the shaded part of the rectangle is 125 square meters.

Area is the measure of the size of a two-dimensional surface or region. It is typically measured in square units, such as square meters or square feet. The area of a shape is the amount of space that it occupies within a defined boundary. The formula for the area of a shape varies depending on the shape, but for common shapes like rectangles, triangles, and circles, there are specific formulas that can be used to calculate the area. Knowing the area of a shape is important for many practical purposes, such as calculating the amount of paint needed to cover a wall or the amount of carpet needed to cover a floor.

Here,

To find the area of the shaded part of the rectangle, we need to subtract the area of the unshaded triangle from the total area of the rectangle. The rectangle has a length of 16 meters and a width of 10 meters, so its total area is:

Area of rectangle = length x width

= 16 m x 10 m

= 160 m²

The unshaded triangle has a base of 9 meters and a height of 10 meters, so its area is:

Area of triangle = 1/2 x base x height

= 1/2 x 7 m x 10 m

= 35 m²

Therefore, the area of the shaded part of the rectangle is:

Area of shaded part = Area of rectangle - Area of triangle

Answer: Let's call the portions that the second friend gets "x". Then, the third friend gets four times that amount, which is 4x. Finally, the first friend gets four times the third friend's portion, which is 4(4x) = 16x.

The sum of the portions is equal to the total prize money of $273,000, so:

x + 4x + 16x = 273000

21x = 273000

The Venn diagram for (D ⋃ E) ⋃ F will be the ovarlapped region of D,E and F.

A Venn diagram is a graphical representation of set theory that uses circles or other closed shapes to show the relationships between sets of objects. In a Venn diagram, each set is represented by a circle or other shape, and the area of the circle represents the total number of objects in that set.

The circles are usually drawn so that they overlap, with the overlapping region representing the objects that belong to both sets. Venn diagrams can be used to illustrate set operations such as union, intersection, and complement.

Now,

As i can not draw here

so i will explain it

To create the Venn diagram, we first draw three overlapping circles to represent the sets D, E, and F. We then shade the regions corresponding to the set operations in the expression, starting from the innermost operation and working our way out.

The expression (D ⋃ E) represents the union of sets D and E, so we shade the region where the circles for D and E overlap. This region represents all the elements that are in D or E or both.

Next, we take the union of (D ⋃ E) with F. This means we shade the region where the circle for F overlaps with the region we shaded in the previous step. This region represents all the elements that are in D or E or F or any combination of these sets.

The final Venn diagram should have three overlapping circles, with the region where all three circles overlap shaded to represent (D ⋃ E) ⋃ F.

Step-by-step explanation:

The trigonometric function that does not have a period of 2π is the tangent function, denoted by tan(x).

The period of a trigonometric function is the length of one complete cycle of the function. For the sine and cosine functions, the period is always 2π, which means that the function repeats itself every 2π units.

However, the tangent function has a period of π, which means that it repeats itself every π units. This is because the tangent function has vertical asymptotes at x = (n + 1/2)π, where n is an integer, and the function changes sign between these asymptotes. Therefore, the tangent function does not have a period of 2π.
