Step-by-step explanation:

x^2-7x=30

x^2-7x-30=0

a = 1, b = -7, c = -30

sqrt(b^2-4ac)

sqrt(49+120)

sqrt(169)

13

-b +/- 13

7 + 13 = 20

7 - 13 = -6

2a = 2

20/2 = 10

-6/2 = -3

we know x>0, so it cant be -3. so now its just 10 - 5

Answer:

The other two co-ordinates are (-3, 5) and (-8, 5).

Step-by-step explanation:

Consider the rectangle ABCD.

A = upper-left coordinates = (-8, 8)

B = upper-right coordinates = (-3, 8)

C = lower-left coordinates

D = lower-right coordinates

Let the side AB form the length of the rectangle.

Compute the distance between the points A and B as follows:

\(AB=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}\)

      \(=\sqrt{(-3+8)^{2}+(8-8)^{2}}\\=\sqrt{(5)^{2}}\\=5\)

The length of the rectangle ABCD is 5 units.

The are of ABCD is given as 15 square units.

Compute the breadth of the rectangle as follows:

\(\text{Area}=\text{l}\times\text{b}\\15=5\times\text{b}\\b=3\)

So, the breadth of the rectangle is 3 units.

Then from point B, 3 units below would be (-3, 5).

And from point A, 3 units below would be (-8, 5).

The rectangle on the coordinate plane is attached below.

Step-by-step explanation: The other answer makes no sense, so here is a better view.

Answer:

The operations you see with you eyes are multiplication and addition.

4 times X plus 2 = 10

The operations you don't see are Subtraction and Division.

4x+2=10

Subtract 2 from both sides.

4x+2−2=10−2

4x=8

Divide both sides by 4.

4x/4  =  8/4

x=2

4x plus 2 equal to 10

4x equal to 10 minus 2 which is 8

X is equal to 4 divided by 8

X is equal to 2

The opposite operations are subtraction and division

The fundamental difference between a sample survey with nonresponse and a volunteer sample is the way participants are selected and the biases that may result from each approach. While nonresponse in a sample survey can lead to nonresponse bias, volunteer samples are more susceptible to selection bias.

The fundamental difference between a sample survey of human beings that may suffer from nonresponse and data using a volunteer sample is the way participants are selected and the potential biases that may arise.
In a sample survey, a random selection of individuals is chosen from the target population. However, nonresponse can occur when some of these selected individuals fail to participate or provide incomplete information. This can lead to nonresponse bias, which affects the representativeness of the sample and the accuracy of the results. To minimize nonresponse bias, researchers should ensure that their survey design and data collection methods encourage participation and provide clear instructions for respondents.
On the other hand, a volunteer sample consists of participants who willingly choose to participate in the study, usually in response to an open invitation. This approach is more prone to selection bias, as the individuals who volunteer may not be representative of the target population. They may have certain characteristics or attitudes that motivated them to participate, leading to biased results that may not generalize to the broader population. To address selection bias, researchers should carefully consider the recruitment method and the potential impact of volunteerism on their findings.
In summary, the fundamental difference between a sample survey with nonresponse and a volunteer sample is the way participants are selected and the biases that may result from each approach. While nonresponse in a sample survey can lead to nonresponse bias, volunteer samples are more susceptible to selection bias. Researchers must be mindful of these biases when designing and conducting their studies.

The dilation of the geometric figure with a scale factor of 1/4 about the origin is: J' (-0.5, -0.25), K' (-0.25, 1), L' (0.75, 0.25), M' (0.75, -0.75).

Dilation simply refers to a type of transformation which changes the size of a geometric object, but not its shape. This ultimately implies that, the size of the geometric object would be increased or decreased based on the scale factor used.

Note: Each interval on this graph represents 1 unit.

For the given coordinates, the dilation with a scale factor of 1/4 about the origin or center of dilation (0, 0) should be calculated as follows:

Point J (-2, -1) → Point J' (-2 × 1/4, -1 × 1/4) = Point J' (-0.5, -0.25).

Point K (-1, 4) → Point K' (-1 × 1/4, 4 × 1/4) = Point K' (-0.25, 1).

Point L (3, 1) → Point L' (3 × 1/4, 1 × 1/4) = Point L' (0.75, 0.25).

Answer:

y = -x + 2, B is the answer

b = 2

The position, s(t), of the particle at time t if initially s(0) = 3 is (2) s(t) = 10 - 7 cos(t) - 6 sin(t).

To find the position, s(t), of the particle at time t, we need to integrate the velocity function, v(t), with respect to time:

s(t) = ∫ v(t) dt

Since the velocity function is v(t) = 7 sin(t) - 6 cos(t), we have:

s(t) = ∫ (7 sin(t) - 6 cos(t)) dt

Integrating each term separately, we get:

s(t) = -7 cos(t) - 6 sin(t) + C

where C is the constant of integration.

To find the value of C, we use the initial condition s(0) = 3:

s(0) = -7 cos(0) - 6 sin(0) + C = -7 + C = 3

C = 10, and the position function is:

s(t) = -7 cos(t) - 6 sin(t) + 10

Rewriting this equation in the form of answer choices, we get:

s(t) = 10 - 7 cos(t) - 6 sin(t)

The position, s(t), of the particle at time t, given the initial condition s(0) = 3 and the velocity v(t) = 7sin(t) - 6cos(t), is s(t) = 9 - 7sin(t) - 6cos(t).

To find the position, we integrate the velocity function with respect to time. Integrating the velocity function v(t) = 7sin(t) - 6cos(t) gives us the position function s(t).

The indefinite integral of sin(t) is -cos(t), and the indefinite integral of cos(t) is sin(t). When integrating, we also take into account the initial condition s(0) = 3 to determine the constant term.

Integrating the velocity function, we get:

s(t) = -7cos(t) - 6sin(t) + C

To determine the constant term C, we use the initial condition s(0) = 3:

3 = -7cos(0) - 6sin(0) + C

3 = -7(1) - 6(0) + C

3 = -7 + C

C = 10

Substituting the value of C back into the position function, we obtain:

s(t) = 9 - 7sin(t) - 6cos(t)

Therefore, the position of the particle at time t, with the initial condition s(0) = 3, is given by s(t) = 9 - 7sin(t) - 6cos(t).

A regular octagon is formed by cutting an isosceles right triangle from each of the corners of a square. To find the length of the side of the octagon, we can use the Pythagorean theorem to calculate the length of the hypotenuse of the isosceles right triangle.

In an isosceles right triangle, the two legs have the same length and the hypotenuse is the side opposite the right angle. Since the square has sides of length 2000, half of the side of the square is the leg of the isosceles right triangle.

So the leg of the isosceles right triangle is 2000/2 = 1000.

Applying the Pythagorean theorem to find the hypotenuse of the isosceles right triangle:

c^2 = a^2 + b^2

c = sqrt(a^2 + b^2)

c = sqrt(1000^2 + 1000^2)

c = sqrt(1000000)

c = 1000*sqrt(2)

So the length of each side of the octagon is 1000sqrt(2)

An estimator is unbiased if its expected value equals the true value of the parameter being estimated.

In statistics, an estimator is a statistic that is used to estimate a population parameter. The expected value of an estimator is the average value of the estimator over all possible samples. The true value of the parameter is the value that the parameter would have if we had access to the entire population.

An estimator is unbiased if its expected value equals the true value of the parameter. In other words, an unbiased estimator is one that is not systematically over- or underestimating the true value of the parameter.

There are a number of ways to determine if an estimator is unbiased. One way is to use a mathematical formula to calculate the expected value of the estimator. Another way is to use a statistical software package to conduct a simulation.

If the expected value of the estimator is equal to the true value of the parameter, then the estimator is unbiased. If the expected value of the estimator is not equal to the true value of the parameter, then the estimator is biased.

It is important to note that an unbiased estimator is not necessarily the best estimator. An unbiased estimator may have a large standard error, which means that it is not very precise. A biased estimator with a small standard error may be more precise than an unbiased estimator with a large standard error.

In general, it is important to consider both the bias and the precision of an estimator when choosing an estimator to use.

the plumber will receive $14,630 from selling the promissory note to the bank, which is enough to pay the bill of $14,061.

To calculate how much the plumber will receive after selling the promissory note to the bank, we need to consider the original loan amount, the interest rate, and the time period.

The original loan amount is $14,000, and the promissory note is due in 9 months. However, the plumber sells the note to the bank after 3 months. This means that the bank will receive the remaining 6 months of interest.

To calculate the amount the plumber will receive, we first need to determine the interest accrued on the note. The interest is calculated using the formula: Interest = Principal × Rate × Time.

For the plumber, the interest accrued is: Interest = $14,000 × 9% × 6/12 = $630.

Next, we need to calculate the total amount the plumber will receive, including the interest. The total amount is the sum of the original loan amount and the interest accrued: Total Amount = Principal + Interest = $14,000 + $630 = $14,630.

Now, we can compare the total amount received by the plumber ($14,630) to the bill of $14,061. Since the total amount received is greater than the bill amount, the plumber will have enough to pay the bill.
