When two variables vary along with each other but the data points are loosely scattered around the line of best fit, the correlation is weak correlation.

We need to find the type of correlation when two variables vary along with each other but the data points are loosely scattered around the line of best fit.

A scatter plot helps find the relationship between two variables. This relationship is referred to as a correlation. Based on the correlation, scatter plots can be classified as follows.

A weak positive correlation indicates that, although both variables tend to go up in response to one another, the relationship is not very strong. A strong negative correlation, on the other hand, indicates a strong connection between the two variables, but that one goes up whenever the other one goes down.

Therefore, when two variables vary along with each other but the data points are loosely scattered around the line of best fit, the correlation is weak correlation.

A jacket with an original cost of $82 is on sale. The cost of the deal is $74.50. The percentage change does the discount represent is 9%.

Percentage change = (amount of increase or decrease) / original amount

= original amount-new amount/ original amount

= (82.74.50)/82

=7.5/82

≈0.09

=9%

What is percentage change?

A quantity's percentage change is equal to the ratio of the difference between the quantity's current value and its starting value multiplied by 100. When a quantity's ultimate value is determined by increasing or decreasing a percentage of its original value, there is always a change in the quantity's percentage change (or percent change).

The difference that results from subtracting the old value from the new value, dividing by the old value, and multiplying the result by the old value is the percentage change. Typically, we multiply a fraction by 100 to create a percent.

Step-by-step explanation:

Based on the line of best fit, the approximate maximum depth of a lake that has 31 miles of shoreline is; 142.968 ft

The line of best fit is defined as a straight line which is drawn to pass through a set of plotted data points to give the best and most approximate relationship that exists between such data points.

Now, we are given a table of values that shows the total shoreline in miles which will be represented on the x-axis and then the maximum depth of several area lakes which will be represented on the y-axis.

However, when the geologist found the graph, she arrived at an equation of best fit as;

y = 4.26x + 10.908.

Thus, for 31 miles of shoreline, the approximate maximum depth is;

Approximate maximum depth = 4.26(31) + 10.908.

The dU/dT at constant P and V is simply nR/P.

According to the ideal gas law, PV = nRT, so we can write P = nRT/V. Using this relationship, we can express the internal energy U as a function of P, V, and T:

U = f(P,V,T) = f(nRT/V, V, T)

To find dU/dP at constant V and T, we can use the chain rule:

dU/dP = (∂U/∂P)V,T + (∂U/∂V)P,T(dP/dP)V,T + (∂U/∂T)P,V(dT/dP)V,T

Since V and T are being held constant, we can simplify the second and third terms to just 0:

dU/dP = (∂U/∂P)V,T

To find (∂U/∂P)V,T, we can differentiate f(nRT/V, V, T) with respect to P, keeping V and T constant:

(∂U/∂P)V,T = (∂f/∂P)nRT/V(-nRT/V²) = -nRT/V²

So, dU/dP at constant V and T is simply -nRT/V².

To find dU/dT at constant P and V, we can again use the chain rule:

dU/dT = (∂U/∂T)P,V + (∂U/∂V)P,T(dV/dT)P,V + (∂U/∂P)V,T(dP/dT)P,V

Since P and V are being held constant, we can simplify the third term to just 0:

dU/dT = (∂U/∂T)P,V + (∂U/∂V)P,T(dV/dT)P,V

To find (∂U/∂T)P,V, we can differentiate f(nRT/V, V, T) with respect to T, keeping P and V constant:

(∂U/∂T)P,V = (∂f/∂T)nRT/V(1) = nR/V

To find (∂U/∂V)P,T, we can differentiate f(nRT/V, V, T) with respect to V, keeping P and T constant:

(∂U/∂V)P,T = (∂f/∂V)nRT/V(-nRT/V²) + (∂f/∂V)V,T = nRT/V² - nRT/V² = 0

Since the ideal gas law shows that PV = nRT, we can write V = nRT/P. Using this relationship, we can simplify the second term of dU/dT to just:

dU/dT = (∂U/∂T)P,V = nR/P

So, dU/dT at constant P and V is simply nR/P.

a. To find dU/dPv, we need to differentiate U with respect to both P and V while treating T as a constant. Using the chain rule, we have:

dU/dPv = (∂U/∂P)v + (∂U/∂V)p * (dV/dP)v

Since U is a function of P, V, and T, we can express it as U(P,V,T). Using the ideal gas law, we substitute P = nRT/V into U:

U = f(P,V,T) = f(nRT/V, V, T)

Differentiating U with respect to P while treating V and T as constants, we get (∂U/∂P)v = -nRT/V².

Similarly, differentiating U with respect to V while treating P and T as constants, we get (∂U/∂V)p = nRT/V.

Hence, dU/dPv = -nRT/V² + nRT/V * (dV/dP)v.

b. To find dU/dTv, we differentiate U with respect to both T and V while treating P as a constant. Using the chain rule:

dU/dTv = (∂U/∂T)v + (∂U/∂V)t * (dV/dT)v

Differentiating U with respect to T while treating V and P as constants, we get (∂U/∂T)v = (∂f/∂T)v.

Similarly, differentiating U with respect to V while treating T and P as constants, we get (∂U/∂V)t = (∂f/∂V)t.

Hence, dU/dTv = (∂f/∂T)v + (∂f/∂V)t * (dV/dT)v.

Note: The specific form of the function f(P,V,T) is not provided, so we cannot determine the exact values of (∂f/∂T)v, (∂f/∂V)t, and (dV/dT)v without additional information.

Let the number of seats in one row be \(x\), then the number of rows will be \(5x\).

So the total number of seats will be \(x*5x=5x^2\), and that's equal to 180.

We have

\(5x^2=180\\x^2=36\)

The series satisfies the hypotheses of the alternating series test. By using the alternating series test, we can find the value of n for which the nth partial sum of the given series approximates the sum of the series to the desired accuracy. This approach is useful when we need to estimate the sum of a series but cannot evaluate it directly.

To find the value of n for which the nth partial sum of the given series approximates the sum of the series with an error less than 0.00001, we can use the alternating series test.

This test states that if a series satisfies the hypotheses of the alternating series test, then the error between the nth partial sum and the actual sum of the series is less than or equal to the absolute value of the (n+1)th term in the series.
For the given series, the nth term is\([(-1)^{n+1}]/n!,\) which is decreasing and approaching zero as n increases.

Therefore, the series satisfies the hypotheses of the alternating series test. Now, to find the value of n for which the error is less than 0.00001, we need to find the smallest value of n such that the absolute value of the (n+1)th term is less than 0.00001.

We can use a calculator or a computer program to find that value, which is n = 11. This means that the 11th partial sum of the series approximates the sum of the series with an error of less than 0.00001.

In summary, by using the alternating series test, we can find the value of n for which the nth partial sum of the given series approximates the sum of the series to the desired accuracy. This approach is useful when we need to estimate the sum of a series but cannot evaluate it directly.
