Step-by-step explanation:

When designing a simulation using a random number generator to predict scores, the simulated data is likely to be different from the actual statistics from last season.

This is because the simulation relies on random numbers, which introduce an element of randomness into the predictions.

Additionally, the simulation might not capture all the variables and factors that affect scores during a game. Therefore, the simulated data will likely have variations and may not perfectly match the actual statistics from last season.

The standard deviation of the salary for firefighters in Finland is approximately $319.80.

To determine the standard deviation of the salary for firefighters in Finland, we can use the given information about the z-score and mean salary. The z-score is a measure of how many standard deviations an individual's salary is from the mean.

The formula to calculate the z-score is:

z = (x - μ) / σ

Where:

- z is the z-score

- x is the individual's salary

- μ is the mean salary

- σ is the standard deviation

In this case, we are given that the firefighter's salary is $2,291.90 and has a z-score of 0.50 relative to other firefighters in Finland. The mean salary of firefighters in Finland is $2,132.

Using the formula, we can rearrange it to solve for the standard deviation:

σ = (x - μ) / z

Substituting the given values:

σ = ($2,291.90 - $2,132) / 0.50

Calculating this expression:

σ = $159.90 / 0.50

σ ≈ $319.80

Answer:

\(A_4\)

Step-by-step explanation:

The cost of the e-readers and the subscription of their services are

\(A_1(t)=5t+350\)

\(A_2(t)=10t+250\)

\(A_3(t)=499\)

\(A_4(t)=15t+179\)

The functions are of the form

\(A(t)=mt+c\)

Where \(m\) is the monthly subscription cost and \(c\) is the cost of the e-reader.

So, 15 dollars is the highest subscription cost which is of the 4th e-reader.

Hence \(A_4\) has the highest subscription cost.

Step-by-step explanation: The average rate of change of a function f(x) over an interval [a,b] is defined as the ratio of “change in the function values” to the "change in the endpoints of the interval"1. In other words, it is the slope of the line that passes through two points on the graph of f(x)2.

To find the average rate of change of f(x) = x² + x + 4 from x = 2 to x = 4, we can use this formula:

Average rate of change = [f(4) - f(2)] / (4 - 2)

First, we need to plug in x = 4 and x = 2 into f(x) and simplify:

f(4) = (4)² + (4) + 4 f(4) = 16 + 8 f(4) = 24

f(2) = (2)² + (2) + 4 f(2) = 4 + 6 f(2) = 10

Next, we need to subtract f(2) from f(4), and divide by (4 - 2):

Average rate of change = [24 - 10] / (4 - 2) Average rate of change = 14 / 2 Average rate of change = 7

The result is 20.997 if 497 is Divided by 23.67 and tenth 2.099 and hundredth is 0.2099

A decimal is a number that has two parts one is whole number, and the remaining is fractional part. The two parts are separated by a point named decimal point.

Hundredth means the fraction that is equal to one is divided by 100

and tenth of a number means the number is divided by 10.

As example a hundredth of 4444 is 44.44 and tenth of 4444 is 444.4.

We are given two numbers 497 and 23.67

In the above, 497 is a whole number and 23.67 is a decimal number.

In order to divide these, we can multiply the two numbers by 100

and get 49700 and 2367

now 49700 is divided by 2367

and the result is 20.99

In the next, the tenth of 20.99 is 2.099 and hundredth of 20.99 is 0.2099

Dilation factor is 3/2.

Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Finding the dilation's center point is the first step in determining the scale factor. Next, we measure the distances between the center point and various points on the preimage and the image. According to Math Bits Notebook, the scale factor is equal to the ratio of these distances.

Given,

OQ = 10

OQ' = 15

Let dilation factor be r

OQ ×r = OQ'

10× r = 15

r = 3/2

Dilation factor is 3/2.

The learning rate in gradient descent determines the step size and should be not too small or too large, as it can cause the algorithm to converge slowly or overshoot the minimum; adjusting the value of the learning rate can fix the problem, but the optimal value depends on the problem and data set.

According to the given information:

When running gradient descent,

The learning rate α determines the step size taken in each iteration toward the optimal solution.

If α is too small, the algorithm will take small steps and will converge slowly, or may even get stuck in a local minimum.

If α is too large, the algorithm may overshoot the minimum and diverge, or bounce back and forth without converging.

In the scenario described, the learning rate α of 0.5 appears too large, causing J(θ) to increase over time.

This suggests that the algorithm is not converging and is overshooting the minimum.

To fix this,
The value of α can be adjusted by reducing it to a smaller value,

Such as 0.1 or 0.01.

This should allow the algorithm to take smaller steps towards the minimum and eventually converge to a lower value of J(θ).

The sampling distribution of x is normal with μ = 81 and σ = 2, probability that x is greater than 84.9 is 0.0735, probability that x is less than 76.7 is 0.0495., probability that x is between 78.1 and 80.3 is 0.0927.

The sampling distribution of x is normal if the sample size n is large enough.

Here, a simple random sample of size n-49 is obtained from a population that is skewed right with μ-81 and σ-14. Hence, the sampling distribution of x is normal because the sample size is greater than 30; that is, n>30.

(a) Describing the sampling distribution of x:

The standard error of the sample mean is σ / √n = 14 / √49 = 2

So, the sampling distribution of x has a mean of μ = 81 and a standard error of σ/√n = 14/√49 = 2.

The sampling distribution of x is normal with μ = 81 and σ = 2.

(b) Probability that x > 84.9:P(x > 84.9) = P((x - μ) / σ > (84.9 - 81) / 2) = P(z > 1.45) = 0.0735(Where z is the standard normal variable)

Therefore, the probability that x is greater than 84.9 is 0.0735.

(c) Probability that x < 76.7:P(x < 76.7) = P((x - μ) / σ < (76.7 - 81) / 2) = P(z < - 1.65) = 0.0495(Where z is the standard normal variable)

Therefore, the probability that x is less than 76.7 is 0.0495.

(d) Probability that 78.1 < x < 80.3:P(78.1 < x < 80.3) = P((78.1 - μ) / σ < (x - μ) / σ < (80.3 - μ) / σ) = P(- 1.45 < z < - 0.85) = 0.0927(Where z is the standard normal variable)

Therefore, the probability that x is between 78.1 and 80.3 is 0.0927.

Random Sampling will be able to calculate the average value of a population without statistical error.

Each sample has an equal chance of being chosen when using the sampling technique known as random sampling.

When there is little chance of data manipulation, systematic sampling is employed.

A census is a study of every element, person, or aspect of the population.

When a population is divided into clusters, a sample is chosen at random from within each cluster. This process is known as cluster sampling.

Hence, we use Random sampling for not getting statistical errors.

The appropriate domain for the function f(x) = 42 - 15x in the given context can be determined by considering the constraints of the problem.

Tyson has a $50 gift card, and he wants to purchase a belt that costs $8 and x number of shirts that cost $15 each. The function f(x) represents the balance on the gift card after Tyson makes the purchases.

The number of shirts Tyson can purchase depends on the remaining balance on the gift card. Since each shirt costs $15, the maximum number of shirts he can buy is limited by the amount of money left on the gift card.

If we subtract the cost of the belt ($8) and the cost of x shirts ($15x) from the initial balance ($50), we should get a non-negative result, indicating that Tyson has enough money on the gift card to make the purchases.

Therefore, we can set up the inequality:

50 - 8 - 15x ≥ 0

Simplifying, we have:

42 - 15x ≥ 0

Now, we can solve for x:

-15x ≥ -42

Dividing by -15 (remembering to flip the inequality sign), we get:

x ≤ 42/15

x ≤ 2.8

Since x represents the number of shirts Tyson can buy, it should be a whole number. Therefore, the appropriate domain for the function f(x) is:

0 ≤ x ≤ 2, where x is an integer.
