Step-by-step explanation:
For \(g(x)=(x-4)^2+2\), the graph of \(f(x)=x^2\) would need to move 4 units to the right and 2 units up. Hence, the vertex would be \((4,2)\) if we compare the function g(x) with the form \(y=a(x-h)^2+k\).
A circular plate has circumference 23.3 inches. What is the area of this plate? Use 3.14 for pi.
Show steps.
Answers
The area of the circular plate is approximately 43.14 square inches.
What is circle?
A circle is a geometric shape that consists of all points in a plane that are equidistant from a fixed point called the center.
The circumference of a circle can be calculated by the formula:
C = 2πr
where C is the circumference, π (pi) is a constant value approximately equal to 3.14, and r is the radius of the circle.
We are given that the circumference of the circular plate is 23.3 inches, so we can use this information to find the radius:
23.3 = 2πr
Dividing both sides by 2π, we get:
r = 23.3 / (2π) ≈ 3.71 inches
Now that we know the radius, we can use the formula for the area of a circle:
A = πr²
Substituting the value we found for r, we get:
A = π(3.71)²
A = 3.14 × 13.76
A ≈ 43.14 square inches
Therefore, the area of the circular plate is approximately 43.14 square inches.

Please use the following for the next 6 questions. Suppose that the average weekly earnings for employees in general automotive repair shops is $450, and that the population standard deviation for the earnings for such employees is $50. A sample of 100 such employees is selected at random.
1) What is the probability distribution of the average weekly earnings for employees in general automotive repair shops?
2) Find the probability that the average weekly earnings is less than $445.
3) Find the probability that the average weekly earnings is exactly equal to $445.
4) Find the probability that the average weekly earnings is between $445 and $455.
5) In answering the previous 3 questions, did you have to make any assumptions about the population distribution?
6) Now assume that the weekly earnings for employees in all general automotive repair shops is normally distributed, obtain the probability that a given employee will earn more than $480 in a given week.
Answers
1) The probability distribution of the average weekly earnings for employees in general automotive repair shops is the sampling distribution of the sample mean. According to the Central Limit Theorem, if the sample size is large enough, the sampling distribution of the sample mean is approximately normal, with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size.
2) To find the probability that the average weekly earnings is less than $445, we can standardize the sample mean and use a z-table. The z-score for $445 is calculated as follows: z = (445 - 450) / (50 / sqrt(100)) = -1. Using a z-table, we find that the probability that the average weekly earnings is less than $445 is approximately 0.1587.
3) Since we are dealing with a continuous distribution, the probability that the average weekly earnings is exactly equal to any specific value is zero.
4) To find the probability that the average weekly earnings is between $445 and $455, we can subtract the probability that it is less than $445 from the probability that it is less than $455. The z-score for $455 is calculated as follows: z = (455 - 450) / (50 / sqrt(100)) = 1. Using a z-table, we find that the probability that the average weekly earnings is less than $455 is approximately 0.8413. Therefore, the probability that it is between $445 and $455 is approximately 0.8413 - 0.1587 = 0.6826.
5) In answering questions 2-4, we made an assumption about the population distribution based on the Central Limit Theorem. We assumed that since our sample size was large enough (n=100), our sampling distribution would be approximately normal.
6) If we assume that weekly earnings for employees in all general automotive repair shops are normally distributed with a mean of $450 and a standard deviation of $50, then we can calculate the z-score for an employee earning more than $480 in a given week as follows: z = (480 - 450) / 50 = 0.6. Using a z-table, we find that the probability that an employee will earn more than $480 in a given week is approximately 1 - 0.7257 = 0.2743.
Suppose a population contains 20,000 people. All else being equal, a study
based on a population sample that includes which of the following numbers
of respondents would be the most reliable?
A. 200
OB. 20
C. 2000
D. 2
Answers
A study based on a population sample that includes 2000 respondents would be the most reliable out of the given options.
In statistical analysis, the reliability of a study depends on the representativeness and size of the sample.
A larger sample size generally provides more reliable results as it reduces the sampling error and increases the precision of the estimates.
Given that the population contains 20,000 people, we need to consider which number of respondents would yield the most reliable study.
Option A: 200 respondents
This represents only 1% of the population.
While it is better than having just 2 respondents, it may not be sufficient to accurately capture the characteristics of the entire population.
Option B: 20 respondents
This represents only 0.1% of the population.
With such a small sample size, the study would likely suffer from a high sampling error and may not provide reliable results.
Option C: 2000 respondents
This represents 10% of the population.
While it is a larger sample size compared to the previous options, it still only captures a fraction of the population.
The study may provide reasonably reliable results, but there is room for potential sampling error.
Option D: 2 respondents
This represents an extremely small sample size, accounting for only 0.01% of the population.
With such a small sample, the study would be highly susceptible to sampling bias and would likely yield unreliable results.
Based on the options provided, option C with 2000 respondents would be the most reliable study.
Although it does not include the entire population, a sample size of 2000 respondents provides a larger representation of the population and reduces the potential for sampling error.
However, it's important to note that the reliability of a study depends not only on sample size but also on the sampling method, data collection techniques, and other factors that ensure representativeness.

To determine the value of x, we can use the concept of similarity between shapes.
Similar shapes have corresponding sides that are proportional to each other.
Given the dimensions of the first shape as 5, x, and 5, and the dimensions of the second shape as 30, 24, and 30, we can set up the following proportion:
5/x = 30/24
To solve for x, we can cross-multiply:
30 · x = 5 · 24
30x = 120
Dividing both sides of the equation by 30:
x = 120 / 30
x = 4

Answers
Given:
The cost of mixture per pound, M= $5.91.
The quantity of nuts taken first , n=13 pounds.
The cost of nuts per pound, which was taken first, N=$3.10.
The cost of nuts per pound taken second, P=$7.50.
Let p be the quantity of nuts taken second.
Hence, we can write,
\(M(n+p)=Nn+Pp\)Now, put the values in the above equation.
\(\begin{gathered} 5.91\times(13+p)=3.1\times13+7.5\times p \\ 5.91\times13+5.91p=3.1\times13+7.5\times p \\ 5.91p-7.5\times p=3.1\times13-5.91\times13 \\ -1.59p=13(3.1-5.91) \\ -1.59p=13\times(-2.81) \\ -1.59p=-36.53 \\ p=\frac{-36.53}{-1.59} \\ p\cong23\text{ pounds} \end{gathered}\)Therefore, 23 pounds of nuts that cost $7.50 per pound is added to make the mixture.

Given:
Given the conditional statement "If an object weighs 3 kilograms, then the object weighs 300 grams".
Required: Converse, contrapositive and inverse of the statement
Explanation:
The converse of a conditional statement, "If p, then q" is "If q then p".
So, the converse of the given statement is,
"If an object weighs 3000 grams, then the object weighs 3 kilograms".
The contrapositive of a conditional statement, "If p, then q" is "If not q, then not p".
So, the contrapositive of the given statement is "If an object not weighs 3000 grams, then the object not weighs 3 kilograms".
The inverse of a conditional statement "If p, then q" is "If not p, then not q."
So, the inverse of the given conditional statement is "If an object not weighs 3 kilograms, then the object not weighs 3000 grams".
