the domain is `R` and the range is `[18,∞)` in interval notation.

The given function is, `f(x)=2x²+18`.

The domain of a function is the set of values of `x` for which the function is defined. In this case, there is no restriction on the value of `x`.

Therefore, the domain of the function is `R`.

The range of a function is the set of values of `f(x)` that it can take. Here, we can see that the value of `f(x)` is always greater than or equal to `18`. The value of `f(x)` keeps increasing as `x` increases. Hence, there is no lower bound for the range.

Therefore, the range of the function is `[18,∞)`.

Hence, the domain is `R` and the range is `[18,∞)` in interval notation.

These are the numbers.

Given function is f(x,y)=sin(xy+y^2)−x^3y^2. We have to find fxy which means the partial derivative of f with respect to x and then with respect to y. The partial derivative of the function f(x,y) with respect to x and then with respect to y is fxy=cos(xy+y²)·(y)-6xy.

So, firstly we have to find fx which means the partial derivative of f with respect to x.

To find fx, we differentiate f with respect to x by considering y as constant.

The derivative of sin function is cos and the derivative of x³ is 3x².

So we have :

fx = cos(xy+y²)·(y) - 3x²y²

Now we differentiate fx with respect to y to obtain fxy.

Here is the second derivative:

fxy = cos(xy+y²)·(y) - 6xy

By combining these partial derivatives,

we can write that fxy

= cos(xy+y²)·(y) - 6xy.

Therefore, the fxy for the given function f(x,y)

= sin(xy+y²) - x³y² is fxy

= cos(xy+y²)·(y) - 6xy.

The partial derivative of the function f(x,y) with respect to x and then with respect to y is fxy=cos(xy+y²)·(y)-6xy.

Answer:

Here’s the answer! Best of luck.

Step-by-step explanation:

Mandy's actual direct labor rate per hour (AP), rounded to two decimal places, is approximately $42.00.

To find Mandy Company's actual direct labor rate per hour (AP), we need to use the given information and apply the formula for direct labor efficiency variance:

Direct Labor Efficiency Variance = (AQ - SQ) × AP

We are given the following information:

Standard direct labor hours allowed for units produced (SQ) = 3,800

Actual direct labor hours worked (AQ) = 3,650

Direct labor efficiency variance, favorable (F) = $6,300

We can rearrange the formula to solve for AP:

AP = Direct Labor Efficiency Variance / (AQ - SQ)

Substituting the values:

AP = $6,300 / (3,650 - 3,800)

AP = $6,300 / (-150)

AP ≈ -$42 per hour

However, a negative value of direct labor rate variance is called favorable direct labor rate variance, which is the result of the actual rate being less than the standard rate.

Therefore, Mandy's actual direct labor rate per hour (AP), rounded to two decimal places, is approximately $42.00.

The Regular Price is ( Original Price - $73.5).

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Gwen buys 3 identical pairs of shoes at Store.

She save $73.50 after the discount.

So, On each pair she saves= 73.5 /3

                                           = $24.5

The probability that both quartz and tourmaline will be found, but not aquamarine is P(A intersection B) = P(A)*P(B) = 0.80 * 0.36 = 0.29.

The Venn diagram for this situation is as follows:

A: Quartz specimens are found  _____

B: Tourmaline specimens are found  ____

C: Aquamarine specimens are found ____

The probability that both quartz and tourmaline will be found, but not aquamarine is P(A intersection B) = P(A)*P(B) = 0.80 * 0.36 = 0.29.

The probability that quartz will be found, but not tourmaline or aquamarine is P(A) – P(A intersection B) – P(A intersection C) = 0.80 - 0.29 - 0.24 = 0.27.

The probability that none of these types of specimens will be found is 1 – P(A) – P(B) – P(C) + P(A intersection B) + P(A intersection C) + P(B intersection C) = 1 - 0.80 - 0.36 - 0.28 + 0.29 + 0.24 + 0.16 = 0.17.

The probability of A intersection (B union C) is P(A)*P(B union C) = P(A)*(P(B) + P(C) – P(B intersection C)) = 0.80 * (0.36 + 0.28 – 0.16) = 0.41.

Using the probability, if you choose two cards out of a deck of cards, then the chances one is a red face card and the other is a black non-face card is 1/2.

In the given question,

If you choose two cards out of a deck of cards, then we have to find the chances one is a red face card and the other is a black non-face card.

As we know that in a deck having 52 cards. In which 26 are red and 26 are black.

We have to choose a red face card.

As we know that in a deck have 12 face cards. In which 6 red face cards and 6 black face cards.

So the chance of getting red face card is

P(R)=Total number of red face cards/Total number of cards

P(R)=6/52

We have to choose a black non-face card.

We know that in a deck have 6 black face cards and total black cards are 26. So the non face cards are 20.

So the chance of getting black non-face card is

P(B)=Total number of black non-face cards/Total number of cards

P(B)=20/52

Now the chances of getting one is a red face card and the other is a black non-face card is

P(R or B)=P(R)+P(B)

P(R or B)=6/52+20/52

P(R or B)=(6+20)/52

P(R or B)=26/52

P(R or B)=1/2

Hence, if you choose two cards out of a deck of cards, then the chances one is a red face card and the other is a black non-face card is 1/2.

The null hypothesis (H0) states that the average age is equal to or greater than 30.8 years, while the alternative hypothesis (Ha) states that the average age is less than 30.8 years.

In hypothesis testing, we set up the null hypothesis (H0) and the alternative hypothesis (Ha) to investigate a claim or conjecture. In this case, the conjecture is that the average age of a senior surgical resident in the United States is less than 30.8 years old.

The null hypothesis (H0) assumes that the average age is equal to or greater than 30.8 years, and any difference observed in the sample is due to random chance or sampling variability. Therefore, the null hypothesis can be stated as:

H0: The average age of senior surgical residents in the United States is greater than or equal to 30.8 years.

The alternative hypothesis (Ha) represents the claim or the opposite of the null hypothesis. In this case, the alternative hypothesis states that the average age is less than 30.8 years, indicating that there is a significant difference or evidence against the null hypothesis. Therefore, the alternative hypothesis can be stated as:

Ha: The average age of senior surgical residents in the United States is less than 30.8 years.

The given statement "In performing a lower-tailed z-test for one mean, the value of the test statistic was z=0.51, which would yield a p-value of 0.695." is true because we perform null hypothesis.

In a lower-tailed z-test for one mean, we test a null hypothesis that the population mean (μ) is greater than or equal to a certain value, against an alternative hypothesis that the population mean is less than that value.

To perform the test, we calculate the z-test statistic using the sample mean, sample standard deviation, sample size, and the hypothesized population mean. If the calculated z-test statistic falls in the rejection region (below the critical value), we reject the null hypothesis and conclude that the population mean is less than the hypothesized value.

In this case, the calculated z-test statistic is 0.51, which falls in the non-rejection region (above the critical value) for a lower-tailed test with a significance level of 0.05. Therefore, the p-value is greater than 0.05, and we do not reject the null hypothesis. The statement that the p-value is 0.695 is consistent with this conclusion.

a. The unemployment rate is 20%.

b. The labor-force participation rate is 60%.

According to the question,

Working age population- 100,000

Labour force - 60,000

Unemployed - 12000 instructions

a) The unemployment rate is the percentage of the labor force that is unemployed and it is calculated as follows:

Unemployment Rate = \(\frac{Number of unemployed People}{Labor force}\) × 100

When an unemployed population is 12,000 and the labor force is 60,000,

the unemployment rate is  = \(\frac{12000}{60000}\) × 100 = 20%

b) labor force participation rate is the percentage of working adult population that participates in labor either by actively looking for a job, or working. It is calculated as follows:

Labor Force Participation Rate = \(\frac{Labor force}{working age population}\) × 100

When the labor force is 60,000 and the working-age population is 100,000

Labor Force Participation Rate = \(\frac{60000}{100000}\) × 100 = 60%
