If X and Y are any random variables with E(X) = 5, E(Y) = 6, E(XY) = 21, V(X) = 9 and V(Y) = 10, then the relationship between x and y is a strong negative relationship.

A simple random sample can be defined as a subset of items that are selected from a statistical population or larger data set, and each member of the subset has an equal or the same probability of being selected.

This ultimately implies that, each member of the subset are selected randomly and by chance, and as such a simple random sample is an unbiased representation of a statistical population.

By calculating the covariance using the following expression, we have:

Cov(X, Y) = E(XY) - E(X)E(Y).

E(X) = 5, E(Y) = 6 and E(XY) = 21.

In conclusion, we can infer and logically deduce that the relationship between x and y is a strong negative relationship.

We reflect the point (-5, -3) over the x-axis to get (-5, 3), and then translate this point down by 2 units to get the final coordinates of (-5, 1).

To reflect a point over the x-axis, we keep the x-coordinate the same, but negate the y-coordinate. Thus, reflecting the point (-5, -3) over the x-axis gives us the point (-5, 3).

Next, we need to translate the result 2 units down. To do this, we subtract 2 from the y-coordinate of the reflected point. So, subtracting 2 from the y-coordinate of (-5, 3) gives us the final coordinates:

(-5, 3) translated 2 units down is (-5, 1).

In summary, we can reflect a point over the x-axis by negating the y-coordinate, and translate a point down by subtracting a value from its y-coordinate. So, we reflect the point (-5, -3) over the x-axis to get (-5, 3), and then translate this point down by 2 units to get the final coordinates of (-5, 1).

(a) Construct confidence intervals are : 90%: [428.95, 444.05], 95%: [427.13, 445.87], 99%: [423.67, 449.33].

(b) The 99% confidence interval has the widest interval.

(a) To construct confidence intervals for the mean breaking strength of the wool fibers, we shall use the given formula:

Confidence interval = sample mean ± (critical value * standard error)

The critical value here will depends on the level of confidence. For a 90% confidence level, the critical value is 1.645 (from the standard normal distribution). For a 95% confidence level, the critical value is 1.96, and for a 99% confidence level, the critical value is 2.576.

Standard error is obtained by dividing the sample standard deviation by the square root of the sample size.

Plugging in the values, we can calculate the confidence intervals:

90% confidence interval:

Lower bound = 436.5 - (1.645 * (11.9 / √20))

Upper bound = 436.5 + (1.645 * (11.9 / √20))

95% confidence interval:

Lower bound = 436.5 - (1.96 * (11.9 / √20))

Upper bound = 436.5 + (1.96 * (11.9 / √20))

99% confidence interval:

Lower bound = 436.5 - (2.576 * (11.9 / √20))

Upper bound = 436.5 + (2.576 * (11.9 / √20))

(b) The width of a confidence interval depends on both the critical value and the standard error. When aiming for a higher level of confidence, the interval becomes wider as it requires a larger critical value. Consequently, it can be concluded that among the given confidence intervals, the one with a 99% confidence level will have the broadest range.

i. By solving the given differential equation and using the initial condition, the expression for y in terms of x is y = 2x - x^2 + 5x + C, where C is the constant of integration. ii. The integral of 5(x+3)(x+5)dx can be found by expanding the expression and using the power rule of integration. The result is ∫5(x+3)(x+5)dx = (5/3)x^3 + 20x^2 + 75x + C, where C is the constant of integration.

i. To find the expression for y in terms of x, we first solve the given differential equation. We have dy = x/(3 - x)dx. By separating variables, we can rewrite the equation as dy/(x) = dx/(3 - x). Integrating both sides, we get ∫dy/(x) = ∫dx/(3 - x). This simplifies to ln|x| = -ln|3 - x| + C, where C is the constant of integration. Exponentiating both sides, we have |x| = e^(C - ln|3 - x|).

Since y = 11 when x = -1, we can substitute these values into the equation to find the value of the constant C. Solving for C, we get C = ln(4). Substituting C back into the equation, we have |x| = e^(ln(4) - ln|3 - x|). Simplifying further, we get |x| = 4/(3 - x). Solving for x, we get x = 3 or x = -5. Thus, the expression for y in terms of x is y = 2x - x^2 + 5x + C, where C is the constant of integration.

ii. To find the integral of 5(x+3)(x+5)dx, we expand the expression to get 5x^2 + 20x + 15x + 75. We can then integrate each term separately. Using the power rule of integration, we have ∫5x^2dx + ∫20xdx + ∫15xdx + ∫75dx.

Integrating each term, we get (5/3)x^3 + 10x^2 + (15/2)x^2 + 75x + C, where C is the constant of integration. Simplifying further, we have (5/3)x^3 + 20x^2 + 75x + C. Thus, the integral of 5(x+3)(x+5)dx is (5/3)x^3 + 20x^2 + 75x + C, where C is the constant of integration.

Answer:

(1/2, 9/2)

Step-by-step explanation:

Write the system as a column (not as a row of characters):

x − 3y = –13 and 5x + 7y = 34 =>

x − 3y = –13

5x + 7y = 34

Let's eliminate x using the method of addition and subtraction.  Multiply all terms of the first row by -5:

-5x + 15y = 65

5x + 7y = 34

The sum of these two equations is

         22y = 99, and so

               y = 9/2

Substituting 9/2 or y in the first equation, we get:

   x - 3(9/2) = -13, which simplifies to:

   x               =  27/2 - 13, or

   x               =  27/2 - 26/2, or x = 1/2

Then the solution is (1/2, 9/2)

As the per pound grown beans price is given than it is reasonable to find the cost price for the 3 pound grown beans by the farmer

So,

Price per pound of bean grown = $1.25

Price of 3 pound of bean grown = 3 x 1.25

By using unitary method, we found that the cost of 5m cloth is Rs. 1050.

According to the unitary method, the cost of 1 meter of cloth is equal to the total cost of 7 meters of cloth divided by 7. That is,

Cost of 1m cloth = Total cost of 7m cloth/7

We know that the total cost of 7m cloth is Rs. 1470. Therefore,

Cost of 1m cloth = 1470/7

Cost of 1m cloth = Rs. 210

This means that the cost of 1 meter of cloth is Rs. 210. Now, we need to find the cost of 5m cloth. To do that, we can use the unitary method again.

Cost of 5m cloth = Cost of 1m cloth x 5

Cost of 5m cloth = Rs. 210 x 5

Cost of 5m cloth = Rs. 1050

Therefore, the cost of 5m cloth is Rs. 1050.

Answer:

Paul should be wearing a light jacket appropriate for about 59 F or 15 °C

Step-by-step explanation:

If it is 4:00 a.m. in Honolulu when it is 2:00 p.m. in London, then the difference between times is:

\(d=14-4\\d=10\ hours\)

London is 10 hours ahead of Honolulu.

If Paul left Honolulu at 12:00 p.m, the corresponding time in London was:

\(t=12+10\\t=22 = 10:00\ p.m.\)

Since he arrived in London at 1:00 p.m. at Friday, the flight time was:

\(F= (24-22)+13\\F=15\ hours\)

The flight took 15 hours in total. If the temperature was 30°C when he boarded the flight and it decreases at a rate of 1°C per hour, the temperature when Paul arrives in London is:

\(T=30-(15*1)\\T=15^oC\)
