The probability of hitting the bull's-eye all three times when throwing darts can be calculated using the multiplication rule of probability as P(3 hits) = p x p x p = \(p^3\),

where p is the probability of hitting the bull's-eye on each throw.

When throwing darts at a dart board, the probability of striking the bull's-eye is affected by many factors, such as the player's skill, the distance from the board, the type of dart used, and so on.

However, assuming that the probability of hitting the bull's-eye is the same for each throw and independent of previous throws;

We can calculate the probability of hitting the bull's-eye all three times using the multiplication rule of probability.

Suppose the probability of hitting the bull's-eye on each throw is p. Then, the probability of missing the bull's-eye on each throw is 1 - p.

The probability of hitting the bull's-eye all three times can be calculated as follows:

P(3 hits) = p x p x p = \(p^3\)

For example, if p = 0.05 (or 5%), then the probability of hitting the bull's-eye all three times would be:

P(3 hits) = 0.05 x 0.05 x 0.05 = 0.000125 or 0.0125%

This means that the chance of hitting the bull's-eye all three times is very low, and it would require a lot of skill and luck to achieve such a feat.

However, the probability of hitting the bull's-eye at least once in three throws would be much higher, and it would depend on the player's skill and consistency.

Overall, the probability of hitting the bull's-eye all three times is quite low, and it is more likely that a player will hit it once or twice or miss it altogether.

Nonetheless, the thrill of the game lies in the challenge and the unpredictability of each throw, making darts a popular game of skill and chance.

The value of the postfix expression 6 3 2 4 + - * is 18, which falls between 15 and 100. Therefore, the correct answer is d) Something between 15 and 100.

Here is the step-by-step  of how to evaluate the postfix expression:

1. Start with the first two numbers, 6 and 3, and the first operator, *. Multiply 6 and 3 to get 18.
2. Move on to the next two numbers, 2 and 4, and the next operator, +. Add 2 and 4 to get 6.
3. Now you have 18 and 6, and the last operator, -. Subtract 6 from 18 to get 12.
4. The final result is 12.

Therefore, the value of the postfix expression 6 3 2 4 + - * is 12, which falls between 15 and 100. The correct answer is d) Something between 15 and 100.

The integer that represents the given situation is a positive 31.

The temperature being 31 degrees above zero means that it is warmer than the freezing point of water. In this context, "above zero" refers to the Celsius or Fahrenheit scale, where zero represents the freezing point of water. Therefore, a temperature of 31 degrees above zero is a positive value indicating a warm temperature.

In this case, it can be assumed that the temperature is being measured in Celsius since 31 degrees above zero on the Fahrenheit scale would correspond to a very high temperature of approximately 87 degrees Fahrenheit. Overall, the integer that represents this situation is positive 31, which signifies a warm temperature above the freezing point.

To find the surface area of a rectangular prism, we need to find the area of each face and add them up.

The prism has six faces: two identical rectangular faces on the top and bottom, and four rectangular faces on the sides.

To find the area of each face, we multiply the length and width of the face.

Top and bottom faces:

Length = 6 ft

Width = 3 ft

Area = 6 ft x 3 ft = 18 ft^2

Since there are two of these faces, their combined area is 2 x 18 = 36 ft^2

Side faces:

Length = 9 ft

Width = 3 ft

Area = 9 ft x 3 ft = 27 ft^2

Since there are four of these faces, their combined area is 4 x 27 = 108 ft^2

To find the total surface area, we add up the areas of all six faces:

Total surface area = 2(top and bottom faces) + 4(side faces)

Total surface area = 2(36 ft^2) + 4(108 ft^2)

Total surface area = 72 ft^2 + 432 ft^2

Total surface area = 504 ft^2

Therefore, the surface area of the given rectangular prism is 504 square feet.

Here, we want to get the probability that the number chosen is less than 5

There are 10 numbers to choose from

The numbers less than 5 are 1,2, 3, 4

Thus, we have the probability as:

(fog)(2) = f(g(2)) = f(√(2-2)) = f(√0) = f(0) = 0² + 14 = 14, (gof)(2) = g(f(2)) = g(2² + 14) = g(18) = √(18-2) = √16 = 4, (fog)(x) = f(g(x)) = f(√(x-2)) = (√(x-2))² + 14 = x - 2 + 14 = x + 12,(gof)(x) = g(f(x)) = g(x² + 14) = √((x² + 14) - 2) = √(x² + 12)

To find (fog)(2), we first evaluate g(2) which gives us √(2-2) = √0 = 0. Then, we substitute this result into f(x), giving us f(0) = 0² + 14 = 14.

For (gof)(2), we first evaluate f(2) which gives us 2² + 14 = 18. Then, we substitute this result into g(x), giving us g(18) = √(18-2) = √16 = 4.

To find (fog)(x), we substitute g(x) = √(x-2) into f(x), resulting in (√(x-2))² + 14 = x - 2 + 14 = x + 12.

Similarly, for (gof)(x), we substitute f(x) = x² + 14 into g(x), resulting in g(x² + 14) = √((x² + 14) - 2) = √(x² + 12).

The particular solution to the given differential equation is: y = x^2 - (2^x)(ln2)/ln2 - 1.

The differential equation is dy/dx = 2x - (2^x)(ln2). To find the particular solution, we need to integrate both sides of the equation with respect to x.

∫dy = ∫(2x - (2^x)(ln2))dx

y = x^2 - (2^x)(ln2)/ln2 + C

To find the value of C, we can use the initial condition that y = -2 when x = 0.

-2 = 0^2 - (2^0)(ln2)/ln2 + C

-2 = -1 + C

C = -1

Therefore, the particular solution to the given differential equation is:

y = x^2 - (2^x)(ln2)/ln2 - 1

In summary, the particular solution to the given differential equation is y = x^2 - (2^x)(ln2)/ln2 - 1, obtained by integrating and using the given initial condition.

Answer:

{− 4 1/2,  −3/4, 0}

Step-by-step explanation:

In mathematics, a number is considered to be "even" if it is divisible by 2, and "odd" if it is not divisible by 2. The numbers from 1 to 100 can be divided into two groups: even numbers and odd numbers.

Even numbers are numbers that are divisible by 2, such as 2, 4, 6, 8, and so on. When you divide an even number by 2, the remainder will always be 0. Some examples of even numbers between 1 and 100 include: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 98, and 100.

Odd numbers are numbers that are not divisible by 2, such as 1, 3, 5, 7, and so on. When you divide an odd number by 2, the remainder will always be 1. Some examples of odd numbers between 1 and 100 include: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73, 75, 77, 79, 81, 83, 85, 87, 89, 91, 93, 95, 97, and 99.

It is important to note that 0 is not a positive or negative number and it is not considered as odd or even.

Knowing the difference between even and odd numbers is an important concept in math, especially when working with patterns, sequences, and operations. Understanding even and odd numbers can help you better understand the properties of numbers and how they can be used in different contexts.

Step-by-step explanation:

Let \(f(x) = x^{2}+10\), the average rate of change on the interval \([a,b]\) is represented by the definition of the secant line:

\(\bar f = \frac{f(b) -f(a)}{b-a}\) (1)

Where:

\(a\), \(b\) - Lower and upper bounds, dimensionless.

\(f(a)\), \(f(b)\) - Function evaluated at lower and upper bounds, dimensionless.

Now we proceed to check each option:

A. \(a = -3\), \(b = 3\)

\(\bar f = \frac{19-19}{3-(-3)}\)

\(\bar f = 0\)
