The ordered pair which is a solution to the system of linear equations (0,2).

In mathematics, a system of linear equations refers to a collection of one or more linear equations which involve the same variables. In order to solve the system of linear equations, multiply each equation by a constant such as the coefficient of one variable becomes the same.

Hence, multiply 2x + 3y= 6 by 3 and –3x + 5y = 10 by 2.

3 (2x + 3y= 6)

6x + 9y = 18

2(–3x + 5y = 10)

-6x + 10 y = 20

Adding the two equations

6x + 9y = 18

-6x + 10 y = 20

19y = 38

y = 2

Substitute y in either of the equations:

2x + 3(2)= 6

2x = 6 – 6 = 0

x = 0

Hence, the solution is (0, 2)

The ordered pair (0,0) is not a solution as it will invalid the given linear equation.

90% confidence interval for positive difference between means that there is a 90% probability that the confidence interval will contain the true population mean

The difference in sample means is used to calculate the difference in population means. A confidence interval reveals how accurate the estimate is.

We will make three assumptions in order to build a confidence interval:

1. The variance between the two populations is equal. The second assumption of homogeneity of variance is what this premise is known as.

3. The populations are evenly distributed.

4. Each value is sampled separately from every other value.

The following formula is used to construct a confidence range for the mean difference:

As Company will not invest in both cases, decision to invest is not sensitive over this annual revenue range.

In the given question, Decker scientific is considering an investment of $850,000 in a new product line.

The company will make the investment only if it will result in a rate of return of 20% per year or higher.

If the revenue is expected to be between $290,000 and $325,000 per year for each of 5 years, we have to determine if the decision to invest is sensitive to the projected range of income using an annual worth analysis.

AW of investment when expected revenue is

290000 = -1080000*(A/P,20%,4) + 290000

A/P = -1080000*0.386289 + 290000

A/P = -127192.12

A/P = -127192

AW of investment when expected revenue is

369000 = -1080000*(A/P,20%,4) + 369000

a) A is better for the better experiment. A creates similar with respect to forest exposure. This are because of the orthogonal effect in quadratic main model.

b) Randomization of variety of trees to plot within each block reduces any bias due to comforting variable.

Blocking Scheme:

In this subsection, the goal is to construct a blocking design such that the blocking effects are orthogonal to the terms in the linear main effects model so that a linear plus quadratic main effects model can be estimated. Assume that all m-factors are quantitative and an m0-factor DSD is constructed. where m0 = m + k and n = 2(m + k) + 1 runs.  Removing the intermediate run from  results in a 2(m + k) run design.

Randomization:

When you randomize an experiment, you select subjects at random. For example, you can use simple random sampling. In this case, participant names are randomly drawn from a pool with each having an equal probability of being selected. You can also randomly assign treatments to participants by assigning random numbers from a random number table.

If you use randomization in your experiments, protect yourself from bias. For example, selection bias (where some groups are underrepresented) is eliminated and accidental bias (where random imbalance occurs) is minimized. If your sample is random, you can also run various statistical tests on the data (to test hypotheses).

In the given question, we have to find a parametrization of the boundary curve as with positive orientation if

1. S is the part of the surface of the paraboloid z = 6-X^2-y^2 above the plane z=-3 with a normal vector pointing upward.

a. (√6 cos(t), √6 sin(t), 0)

b. (√6 cos(t), √6 sin(t), -3)

c. (3 cos(t), – 3 sin(t), -3)

d. (3 cos(t), 3 sin(t), -3)

e. (3 cos(t), 3 sin(t),0)

The given paraboloid is z = 6-X^2-y^2 above the plane z=-3.

Now convert Cartesian form to the polar equation.

In polar form x=rcost, y=rsint z=z and x^2+y^2=r^2

Now z = 6-X^2-y^2

z = 6-(X^2+y^2)

z = 6-r^2

Now put z=-3

-3 = 6-r^2

Subtract 6 on both side, we get

-r^2 = -9Now r^2 = 9

Taking square root on both side, we get

r=3

Now x=3cost, y=3sint, z= -3

So ∂S = (3cost, 3sint, -3) t=0→2π

Answer:

D) On average, Jennie makes $232.50 less than Paul in a typical cruise.

Step-by-step explantion

Answer:

Before we declare what happens, we must have an understanding of outliers and standard deviation. Outliers are certain points that are x deviations away from the mean. Standard deviation is a measurement of dispersion in relations to the mean you are identifying. Given this information, when outliers are removed, the standard deviation becomes a lower amount, because you have to think of standard deviation as a population measurement in a way. So imagine the outliers are a prestigious group of people, and if they leave the community, the population is indeed lower. Outliers affect deviation by a measure of extremity. The more extreme an outlier, the more or less a standard deviation will be affected. When outliers are removed, they will lower the standard deviation, which changes the data in respect to population. A high outlier, however, will increase both mean and median no matter what.

The given cube root expressions are:

1. [tex]\sqrt[3]{81}[/tex]

Simplifying the first expression, we get

[tex]\sqrt[3]{81}=\sqrt[3]{3\times3\times3}[/tex]

⇒ [tex]\sqrt[3]{81}[/tex] = 3∛3 = 4.3267....

Thus, the cube root of 81 gives an irrational number since it is a non-terminating decimal and has no repeated decimals in it.

Now, simplifying the second expression, we get

[tex]\sqrt[3]{-64}=\sqrt[3]{-4\times-4\times-4}[/tex]

⇒ [tex]\sqrt[3]{-64}[/tex] = -4

Since the result is an integer, the cube root of -64 is a rational number.

2- There are 0 or more child nodes of the root node.

3- There are zero or more child nodes for each child node, and so forth. As a result, the tree gains a subtree. Each node has a separate subtree that consists of its offspring and their offspring, etc. This implies that any node can function as a tree on its own.
