Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

Recall that the sample space for the results obtained by rolling a fair dice is {1,2,3,4,5,6}. So, the total number of outcomes is 6.

Since the desired outcome is rolling an odd number or a number less than 3, so the set of desired outcomes is {1,2,3,5}. Hence, the number of desired outcomes is 4.

Therefore, the required probability is:

[tex]\frac{\text{number of desired outcomes}}{\text{number of all outcomes}}=\frac{4}{6}=\frac{2}{3}[/tex]

Answer:

probability of rolling an odd number or a number less than 3 is [tex]\frac{2}{3}[/tex] or a 2 in 3 chance

Step-by-step explanation:

a die has 6 sides that are numbered 1 to 6.

3 of those sides are even numbers and 3 of those sides are odd numbers.

the question also states LESS THAN 3, which means that it does not include 3 itself, out of the 6 possible numbers, only two of them are less than 3 (1 and 2) so 2 out of 6 sides are less than 3, but one is already included in the probability, then we use the formula

[tex]\frac{number of desired outcomes}{number of total possible outcomes}[/tex] or [tex]\frac{4}{6}[/tex] which can be simplified to [tex]\frac{2}{3}[/tex]

The probability that the mean of the sample will be between 94.7 inches and 95.3 inches is approximately 0.436.

Option B is the correct answer.

We have,

To find the probability that the mean of the sample will be between 94.7 inches and 95.3 inches, we can use the Central Limit Theorem.

According to the Central Limit Theorem, the distribution of sample means approaches a normal distribution as the sample size increases.

In this case, the mean of the population (μ) is 95 inches and the standard deviation of the population (σ) is 0.52 inches.

Since the sample size is sufficiently large (n = 30), we can assume that the distribution of sample means will be approximately normal.

To calculate the probability, we need to standardize the sample mean using the z-score formula:

z = (x - μ) / (σ / √n)

where:

x = sample mean

μ = population mean

σ = population standard deviation

n = sample size

Let's calculate the z-scores for the lower and upper limits:

z1 = (94.7 - 95) / (0.52 / √30)

z2 = (95.3 - 95) / (0.52 / √30)

Now, we can use a standard normal distribution table or a calculator to find the probability associated with these z-scores.

Using a standard normal distribution table or a calculator, we find:

P(z1 < Z < z2) ≈ 0.436

Therefore,

The probability that the mean of the sample will be between 94.7 inches and 95.3 inches is approximately 0.436.

The value of x converges to approximately 2.5615

Given is an equation, we need to solve for x, xˣ = 4ˣ + 16

To solve the equation xˣ = 4ˣ + 16, we'll use algebraic methods. Unfortunately, this equation does not have an explicit algebraic solution that can be found using elementary functions.

However, we can use numerical methods or approximation techniques to find an approximate solution.

One common numerical method for solving equations is the Newton-Raphson method.

Let's apply it to this equation:

Start with an initial guess for x, let's say x = 1.

Iterate using the following formula:

x(n+1) = x(n) - f(x(n)) / f'(x(n))

where f(x) = x^x - 4^x - 16 and f'(x) is the derivative of f(x) with respect to x.

Repeat step 2 until the value of x converges to a solution.

Let's perform a few iterations:

1st iteration:

x(1) = 1 - (1^1 - 4^1 - 16) / (1 * 1^0 - 4 * 4^0)

= 1 - (-11) / (-3)

≈ 3.6667

2nd iteration:

x(2) = 3.6667 - (3.6667^3.6667 - 4^3.6667 - 16) / (3.6667 * 3.6667^2.6667 - 4 * 4^2.6667)

≈ 2.6141

3rd iteration:

x(3) = 2.6141 - (2.6141^2.6141 - 4^2.6141 - 16) / (2.6141 * 2.6141^1.6141 - 4 * 4^1.6141)

≈ 2.5615

By continuing these iterations, you can refine the solution to any desired level of accuracy.

In this case, the value of x converges to approximately 2.5615.

Answer:

In the equation y = 2 cos(5x + 3) - 6, we can ignore the coefficients 2 and -6 for the purposes of calculating the period because they do not change the period. They only change the amplitude (2) and vertical shift (-6) of the function.

The coefficient 5 in front of x inside the cosine function affects the period of the function. It is a horizontal compression/stretch of the graph of the function.

The period of the basic cosine function, y = cos(x), is 2π. When there is a coefficient (let's call it b) in front of x, such as y = cos(bx), the period becomes 2π/b.

So, in your case, b = 5, so the period T of the function y = 2 cos(5x + 3) - 6 is:

T = 2π / 5

This is the simplest form for the period of the given function.

The function values are:

f(-1) = -9

f(1) = -5

We have,

From the graph,

We have the coordinates as:

(-1, -9) (2, 0), (-4, 0), and (1, -5)

Now,

The coordinates mean (x, y).

x is the x-axis and y is the function value.

f(x) = y

So,

We can have,

When x = -1, y = -9 or f(-1) = -9

And,

When x = 1, y = -5 or f(1) = -5

Answer:

k = 6 and k = -4

Step-by-step explanation:

To determine two integral values of k (integer values of k) for which the roots of the quadratic equation kx² - 5x - 1 = 0 will be rational, we can use the Rational Root Theorem.

The Rational Root Theorem states that if a rational number p/q is a root of a polynomial equation with integer coefficients, then p must be a factor of the constant term (in this case, -1) and q must be a factor of the leading coefficient (in this case, k).

Possible p-values:

Possible q-values:

Therefore, all the possible values of p/q are:

[tex]\sf \dfrac{p}{q}=\dfrac{\pm 1}{\pm 1}, \dfrac{\pm 1}{\pm k}=\pm 1, \pm \dfrac{1}{k}[/tex]

To find the integral values of k, we need to check the possible combinations of factors. Substitute each possible rational root into the function:

[tex]\begin{aligned} x=1 \implies k(1)^2-5(1)-1 &= 0 \\k-6 &= 0 \\k&=6\end{aligned}[/tex]

[tex]\begin{aligned} x=-1 \implies k(-1)^2-5(-1)-1 &= 0 \\k+4 &= 0 \\k&=-4\end{aligned}[/tex]

[tex]\begin{aligned} x=\dfrac{1}{k} \implies k\left(\dfrac{1}{k} \right)^2-5\left(\dfrac{1}{k} \right)-1 &= 0 \\\dfrac{1}{k}-\dfrac{5}{k}-1 &= 0 \\-\dfrac{4}{k}&=1\\k&=-4\end{aligned}[/tex]

[tex]\begin{aligned} x=-\dfrac{1}{k} \implies k\left(-\dfrac{1}{k} \right)^2-5\left(-\dfrac{1}{k} \right)-1 &= 0 \\\dfrac{1}{k}+\dfrac{5}{k}-1 &= 0 \\\dfrac{6}{k}&=1\\k&=6\end{aligned}[/tex]

Therefore, the two integral values of k for which the roots of the equation kx² - 5x - 1 = 0 will be rational are k = 6 and k = -4.

Note:

If k = 6, the roots are 1 and -1/6.

If k = -4, the roots are -1 and -1/4.

Answer:

3n = 9n - 110

Step-by-step explanation:

Let's suppose that Patrick and Hall play n number of songs to earn the same amount of money.

For Patrick, the amount of money he earns is given by:

Money earned by Patrick = 3n

For Hall, the amount of money he earns after paying the $110 fee is given by:

Money earned by Hall = 9n - 110

To find the number of songs they will have to play in order to earn the same amount of money, we need to set these two expressions equal to each other and solve for n:

3n = 9n - 110

Simplifying this equation, we get:

6n = 110

Dividing both sides by 6, we get:

n = 110/6

n = 18.33 (rounded to two decimal places)

Since n represents the number of songs, it cannot be a fractional value. Therefore, we can conclude that they will have to play 18 songs to earn the same amount of money.

Therefore, the equation that could be used to find n, the number of songs they will have to play in order to earn the same amount of money, is:

3n = 9n - 110

Algebraically, the amount of money the insurance company will pay, represented as P, is equal to the total value of the stolen items (2b + t) minus the deductible (d).

Let's denote the amount of money the insurance company will pay as P. In this scenario, if the value of the stolen items is greater than the deductible, the insurance company will cover the loss, and Ron will receive compensation for the stolen items.

The total value of the stolen items can be calculated by adding the value of the bicycles (2b) and the value of the tools (t). So, the total value of the stolen items is 2b + t.

If the total value of the stolen items is greater than the deductible (d), then the insurance company will pay the difference between the total value and the deductible. Mathematically, this can be represented as:

P = (2b + t) - d

Therefore, algebraically, the amount of money the insurance company will pay, represented as P, is equal to the total value of the stolen items (2b + t) minus the deductible (d).
