The perimeter of the shape is approximately 20.57 inches.

The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape. The perimeter of different figures can be equal in measure depending upon the dimensions.

The shape consists of two shapes; a square and 2 semi-circles

Perimeter of square = 4L

where L = 2 inches

Perimeter = 4(2)

Perimeter = 8 inches

Perimeter of Semi-circle = [tex]\pi r}[/tex]

where [tex]\pi = 3.142[/tex]

r = 2 inches

Perimeter of Semi-circle = 3.142 x 2

Perimeter of Semi-circle = 6.284 inches

Perimeter of shape = Perimeter of square + 2 x Perimeter of Semi-circle

Perimeter of shape = 8 inches + 2 x  6.284 inches

Perimeter of shape = 8 inches + 12.568 inches

The range of probability is:

​c. ​zero to one

Probability is a measure of the likelihood of an event occurring. It is a value that ranges between 0 and 1, where 0 represents an impossible event, and 1 represents a particular event. In other words, a probability of 0 means that an event will not happen, and a probability of 1 means that an event will happen. Any probability value between 0 and 1 can be written as a decimal or a percentage. For example, a probability of 0.5 can also be written as 50%.

It is important to note that probability values cannot be negative or greater than 1. In probability theory, events that are impossible to happen have a probability of 0, and events that are certain to happen have a probability of 1. For example, a probability value of 0.5 means a 50% chance of an event and a 50% chance of it not happening. Therefore, the range of probability is between 0 and 1, as any value outside of this range would not be a valid probability.

Step-by-step explanation:

The high category cost in Spain is 57.8% lower than the high category cost in the United States, while the medium category cost in Spain is 61.0% lower than the medium category cost in the United States.

We can use the following calculations to determine the percentage by which Spain's high category and medium category costs are less than those of the United States' categories:

(High in the US - High in Spain)/High in the US * 100%

Spanish medium/US medium * 100% for the medium division.

 The first formula determines the percentage difference between the high category costs in the United States and Spain. The second calculation determines the percentage difference between the medium category costs in the United States and Spain.

 Calculate, for instance, the percentage difference between the high category costs in Spain and the United States. The values can be entered into the formula in the following way:

High category: (19.97)/(34.48 - 14.51)/(34.48 * 100%) = 57.8%

This indicates that the high category cost in Spain is 57.8% cheaper than the high category cost in the United States.

The similar method can be used to determine how much less Spain's medium category cost is than America's medium category cost:

(22.46 - 8.79)/22.46 * 100% = (13.67)/22.46 * 100% = 61.0% for the medium group.

   As a result, the medium category cost in Spain is 61.0% cheaper than the medium category cost in the United States.

Compare the costs for the two programs and results are when the number of classes are more, canoeing is less expensive and when the number of classes are less, fishing is less expensive.

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

The graph and the table show the total costs of two different summer programs, y, as functions of the two different summer programs, y, as a function of the number of classes, x.

For canoeing program,

And number of class 1 then cost is $32.

The number of classes 2 then y = 44

For each, 44/2 = $22

The number of classes 3 then y = 56

For each, 56/3 = $18.67

The number of classes 2 then y = 68

For each, 68/4 = $17

So,

When the number of classes are more, canoeing is less expensive.

And number of class 1 then cost is $20.

The number of classes 2 then y = 40

For each, 40/2 = $20

The number of classes 3 then y = 60

For each, 60/3 = $20

The number of classes 2 then y = 80

For each, 80/4 = $20

So,

When the number of classes are less, fishing is less expensive.

Therefore, when the number of classes are more, canoeing is less expensive and when the number of classes are less, fishing is less expensive.

First, we can get rid of the fraction on the left side of the equation by multiplying both sides by 5:

5 * (x + 28) / 5 = 5 * (3x) / 5

This simplifies to:

x + 28 = 3x

Then, we can subtract x from both sides to get:

x + 28 - x = 3x - x

This simplifies to:

28 = 2x

Finally, we can divide both sides by 2 to find the value of x:

By applying the polar equation of a rose curve, we can conclude that the rose curve will have 3 petals whose each length is 10 units. The endpoints of each petal occur when θ = 0, π/3, 2π/3. The corresponding values of the endpoint of each petal (r,θ) are (-10,0), (10,π/3), (-10,2π/3).

The polar equation of a rose curve is either:

r = a cos (nθ) or r = a sin (nθ)

where

a = constant that determines the size

n = half of the number of petals (n is even) or number of petals (n is odd)

We take a look at the given function: r = 10 sin 3θ

By applying the rule above, we can conclude that the rose curve will have 3 petals whose each length is 10 units.

Now we want to know the starting point of the petals, we assume the r = 0.

r = 10 sin 3θ

0 = 10 sin 3θ

0 = sin 3θ

3θ = 0 + nπ

θ = nπ/3   n = number of petal + 1 = 0, 1, 2, 3

The equation y=ax^b, where a and b are constants. If the points follow this equation, then the set of points is an exponential function.

An exponential function is a function in which the output is proportional to the exponent of the input. Exponential functions follow the equation y=ax^b, where a and b are constants. To determine if a set of points is an exponential function, you must look for a pattern in the points that follows the equation. If the points follow the equation, then the set of points is an exponential function. If the points do not follow the equation, then the set of points is not an exponential function. An example of an exponential function is y=2^x, where the output, y, is proportional to the exponent of the input, x.

The volume of a conical tank can be calculated using the formula V = 13r2h, where r is the radius and h is the height. Using this formula, we can calculate the volume of the tank to be 13(12)2(26) = 7584 ft3.

Next, we need to calculate the rate at which the depth of the water is increasing. This can be done by dividing the rate at which water is flowing into the tank (20 ft3/min) by the volume of the tank (7584 ft3). This gives us a rate of 0.0026 ft3/min. To get the rate at which the depth is increasing, we need to divide this number by the area of the tank's base (113 ft2). This gives us a rate of 0.167 ft.
