Total pay = Regular pay + Overtime pay = $280 + $616 = $896. Therefore, if Lisa works 42 hours in one week, she would be paid $896

The first step is to calculate Lisa's regular pay for the week. We know that her regular hourly rate is $8 per hour. If she works 35 hours or less in a week, then her pay is simply her hourly rate times the number of hours worked. Therefore, her regular pay for a week where she works 35 hours or less would be:

Regular pay = $8/hour * 35 hours = $280

However, we know that Lisa worked 42 hours in one week, which is more than 35 hours. This means she also worked 7 overtime hours. According to the problem, Lisa is paid 11 times her regular salary for any overtime hours worked. This means her overtime pay for the 7 overtime hours would be:

Overtime pay = $8/hour * 11 * 7 hours = $616

To get Lisa's total pay for the week, we simply add her regular pay and overtime pay together:

Total pay = Regular pay + Overtime pay = $280 + $616 = $896

Answer:

\(\dfrac{1}{729}\)

Step-by-step explanation:

\(\left(\dfrac{}{}(-3)^2\dfrac{}{}\right)^{-3}\)

First, we should evaluate inside the large parentheses:

\((-3)^2 = (-3)\cdot (-3) = 9\)

We know that a number to a positive exponent is equal to the base number multiplied by itself as many times as the exponent. For example,

\(4^3 = 4 \, \cdot\, 4\, \cdot \,4\)

       ↑1 ↑2 ↑3 times because the exponent is 3

Next, we can put the value 9 into where \((-3)^2\) was originally:

\((9)^{-3}\)

We know that a number to a negative power is equal to 1 divided by that number to the absolute value of that negative power. For example,

\(3^{-2} = \dfrac{1}{3^2} = \dfrac{1}{3\cdot 3} = \dfrac{1}{9}\)

Finally, we can apply this principle to the \(9^{-3}\):

\(9^{-3} = \dfrac{1}{9^3} = \boxed{\dfrac{1}{729}}\)

To determine if the population mean life span for Honolulu is less than 77 years based on the sample information, we can conduct a hypothesis test.

Let's set up the hypotheses: Null hypothesis (H₀): The population mean life span for Honolulu is 77 years. Alternative hypothesis (H₁): The population mean life span for Honolulu is less than 77 years.

We have a sample of 20 obituary notices, and the sample mean and sample standard deviation are not provided in the question. Without the specific sample values, we cannot calculate the p-value directly. However, we can still discuss the general approach to finding the p-value. Using the given assumption that life span in Honolulu is approximately normally distributed, we can use a t-test for small sample sizes. With the sample mean, sample standard deviation, sample size, and assuming a significance level (α), we can calculate the t-statistic.

The t-statistic can be calculated as: t = (sample mean - population mean) / (sample standard deviation / sqrt(sample size))

Once we have the t-statistic, we can determine the p-value associated with it. The p-value represents the probability of obtaining a sample mean as extreme as (or more extreme than) the observed value, assuming the null hypothesis is true. If the p-value is less than the significance level (α), we reject the null hypothesis and conclude that the population mean life span for Honolulu is less than 77 years. If the p-value is greater than α, we fail to reject the null hypothesis.

Without the specific sample values, we cannot calculate the t-statistic and p-value.

Step-by-step explanation:

a. The marginal PMFs of U and V can be obtained by summing over all possible values of the other random variables: P(U = u):\(= sum_{v=-u}^{u} P(U = u, V = v), P(V = v) \\\\= sum_{u=|v|}^{2-|v|} P(U = u, V = v).\)

and b. P(V = -1) = P(X = 1, Y.

a. The joint probability mass function (PMF) of U and V, we can use the definition of U and V and the fact that X and Y are independent Bernoulli(0.5) random variables:

For U = X + Y and V = X - Y, we have:

U = 0 if X = 0 and Y = 0

U = 1 if (X = 0 and Y = 1) or (X = 1 and Y = 0)

U = 2 if X = 1 and Y = 1

V = 0 if X = 0 and Y = 0

V = 1 if (X = 0 and Y = 1) or (X = 1 and Y = 0)

V = -1 if X = 1 and Y = 1

Using the above equations, we can write the joint PMF of U and V as:

P(U = u, V = v) = P(X = (u+v)/2, Y = (u-v)/2)

Since X and Y are independent Bernoulli(0.5) random variables, we have:

P(X = x, Y = y) = P(X = x) * P(Y = y) = 0.5 * 0.5 = 0.25

Therefore, we can write the joint PMF of U and V as:

P(U = u, V = v) =

{ 0.25 if u+v is even and u-v is even, and u+v >= 0

{ 0 otherwise

The marginal PMFs of U and V can be obtained by summing over all possible values of the other variable:

\(P(U = u) = sum_{v=-u}^{u} P(U = u, V = v)\\P(V = v) = sum_{u=|v|}^{2-|v|} P(U = u, V = v)\)

b. To check if U and V are independent, we need to show that their joint PMF factorizes into the product of their marginal PMFs:

P(U = u, V = v) = P(U = u) * P(V = v) for all u and v

Let's consider the case where u+v is even and u-v is even:

P(U = u, V = v) = 0.25

P(U = u) * P(V = v) =

\(sum_{v'=-u}^{u} P(U = u) * P(V = v') * delta_{v,v'}\)

= P(U = u) * P(V = v) + P(U = u) * P(V = -v) if u > 0

= P(U = u) * P(V = 0) if u = 0

delta_{v,v'} is the Kronecker delta function that equals 1 if v = v' and 0 otherwise.

Therefore, U and V are independent if and only if P(U = u) * P(V = v) = P(U = u, V = v) for all u and v.

Now let's compute the marginal PMFs of U and V:

P(U = 0) = P(X = 0, Y = 0) = 0.25

P(U = 1) = P(X = 0, Y = 1) + P(X = 1, Y = 0) = 0.5

P(U = 2) = P(X = 1, Y = 1) = 0.25

P(V = -1) = P(X = 1, Y

The vector field f(x,y) = 33x^2y^2i + 22x^3yj is conservative, and its potential function is φ(x,y) = 11x^3y^2 + 11x^2y^2 + C.

To determine if a vector field is conservative, we need to check if it is the gradient of a scalar function (i.e., a potential function). We can do this by taking the partial derivatives of each component with respect to their respective variables and checking if they are equal:

∂f_x/∂y = 66xy^2
∂f_y/∂x = 66xy^2

Since these partial derivatives are equal, the vector field is conservative. We can then find a potential function by integrating each component with respect to their respective variable:

φ(x,y) = 11x^3y^2 + 11x^2y^2 + C

where C is the constant of integration.

Therefore, the vector field f(x,y) = 33x^2y^2i + 22x^3yj is conservative, and its potential function is φ(x,y) = 11x^3y^2 + 11x^2y^2 + C.

There are 16 individuals in each sample.

To determine the number of individuals in each sample, we need to use the formula for calculating degrees of freedom for independent t-tests, which is df = (n1 + n2) - 2.

Since the researcher reports an independent-measures t statistic with df = 30, we can substitute this value into the formula and solve for the total number of individuals across both samples.

Thus, 30 = (n1 + n2) - 2, which simplifies to n1 + n2 = 32. Since the two samples are the same size (n1 = n2), we can divide the total number of individuals by 2 to get the size of each sample.

The joint probability, Prob(V1 < 0.5, V2 < 0.3), of two uniformly distributed variables V1 and V2, modelled using a Gaussian copula with a correlation coefficient of ρ = 0.5.

Given that V1 and V2 are uniformly distributed between 0.2 and 0.8, we need to transform these variables to standard normal variables before calculating the joint probability. The Gaussian copula is commonly used for this purpose.

The transformation from the uniform distribution to the standard normal distribution can be achieved using the inverse of the cumulative distribution function (CDF) of the standard normal distribution. Let Φ denote the CDF of the standard normal distribution. The transformed variables, denoted as U1 and U2, can be calculated as follows:

U1 = Φ^(-1)(V1)

U2 = Φ^(-1)(V2)

Since the correlation coefficient between U1 and U2 is ρ = 0.5, we can calculate the joint probability using the bivariate normal distribution function with mean 0, standard deviation 1, and correlation coefficient 0.5. Let Φ2 denote the cumulative bivariate normal distribution function.

\(Prob(V1 < 0.5, V2 < 0.3) = Prob(U1 < Φ^(-1)(0.5), U2 < Φ^(-1)(0.3))\)

\(= Φ2(Φ^(-1)(0.5), Φ^(-1)(0.3); ρ = 0.5)\)

Step-by-step explanation:

We can check if they are of equal distance apart by checking if the ratios of the given lines are equal...in other words we must check if LP/PN=MQ/QN

We know that triangle PNQ is inscribed inside triangle LNM

Using the information we have we see that side LP is 18 units, PN is 16 units, MQ is 27, and QN is 24. With this information we can write out LP/PN=MQ/QN and see if it's true.

LP= 18, PN= 16, 18/16= 1.125

MQ= 27, QN=24, 27/24= 1.125
