ax2+2x3−24x+1=y

Step 2: Add -2x^3 to both sides.

ax2+2x3−24x+1+−2x3=y+−2x3

ax2−24x+1=−2x3+y

Step 3: Add 24x to both sides.

ax2−24x+1+24x=−2x3+y+24x

ax2+1=−2x3+24x+y

Step 4: Add -1 to both sides.

ax2+1+−1=−2x3+24x+y+−1

ax2=−2x3+24x+y−1

Answer:

y = 2/5x + 18.

Step-by-step explanation:

The line will have the same slope of 2/5.

Using the point-slope form of a line:

y - 12 = 2/5(x - -15)

y - 12 = 2/5(x + 15)

y = 2/5x + 6 + 12

y = 2/5x + 18.

Answer:

y  = (2/5)*x + 18

Step-by-step explanation:

Because the line is parallel to the line y = 2/5 x + 17, the slope of the new line has to be the same as well. So far, we have y = (2/5)*x .

Now what we can do is plug in -15 for x and see what we get for y. Because we get -6, we need 18 more to make it 12. Because of that, the y-intercept is 18 to make the equation of the line y  = (2/5)*x + 18.

Step-by-step explanation:

hcm is the highest common factor, also know as the gates common divisor.

in other words, what is the biggest expression that divides all given terms without remainder ?

3 divides 24 and 30. that is fine.

every term has one p and at least one r. only 2 out of the 3 terms have a q (so that is not part of it).

therefore, the hcm or gcd is 3pr

lcm is the lowest common multiple.

that means, what is the smallest expression that can be divided by all 3 terms without remainder ?

let's start with the numbers and use the prime factor approach :

3 = 3

24 = 2×2×2×3

30 = 2×3×5

lcm of these 3 numbers is then the combination of the longest streaks of the various prime factors :

2×2×2×3×5 = 120

about the variables

pq²r² can be divided by pqr and also by pr². and, of course, by pq²r² itself too.

so, we don't need to "add" anything.

so, the lcm is 120pq²r²

a) To find the probability that a bearing will wear-out before seven years of service, we need to calculate the area under the normal distribution curve to the left of x = 7. We can use the z-score formula to standardize the value of x:

z = (x - μ) / σ

where μ is the mean, σ is the standard deviation, and x is the value we want to find the probability for. Substituting the given values, we have:

z = (7 - 6) / 1 = 1

Using a standard normal distribution table or calculator, we can find that the probability of a z-score less than 1 is approximately 0.8413. Therefore, the probability that a bearing will wear-out before seven years of service is approximately 0.8413.

b) To find the probability that a bearing will wear-out after seven years of service, we need to calculate the area under the normal distribution curve to the right of x = 7. Using the same z-score formula and substituting the given values, we have:

z = (7 - 6) / 1 = 1

The probability of a z-score greater than 1 is the same as the probability of a z-score less than -1, which is approximately 0.1587. Therefore, the probability that a bearing will wear-out after seven years of service is approximately 0.1587.

c) To find the service life that will provide a wear-out probability of 10%, we need to find the value of x such that the area under the normal distribution curve to the left of x is 0.10. Using a standard normal distribution table or calculator, we can find the z-score that corresponds to a cumulative probability of 0.10, which is approximately -1.28.

Using the z-score formula and substituting the given values, we have:

-1.28 = (x - 6) / 1

Solving for x, we get:

x = 6 - 1.28 = 4.72

Therefore, the service life that will provide a wear-out probability of 10% is approximately 4.72 years

The slope of an inclined object is obtained as the division of the vertical distance of the street by the horizontal distance of the object.

The distances are classified as follows:

The slope of the street is given as follows:

-3.

The east distance is given as follows:

150 yards.

Thus the south distance can be identified applying the slope as follows:

-3 = S/150

S = -3 x 150

S = -450 yards.

The negative number represents that the direction is south, hence the distance is only of 450 yards.

The statement "secondary data should be gathered first because this type of information is less expensive to obtain" is actually false because it has already been collected, there are some important factors to consider.

Primary data is data that is collected specifically for the purpose of the research project at hand. This type of data can include surveys, interviews, experiments, and observations. On the other hand, secondary data is data that has already been collected by someone else for a different purpose.

Firstly, it's important to consider the quality of the data. Secondary data may not always be reliable or up-to-date, which could impact the accuracy of your research findings. In some cases, you may need to spend time and resources verifying the accuracy of the secondary data, which could end up being more expensive in the long run.

Additionally, it's important to consider the specific needs of your research project. Depending on your research question, primary data may be necessary to obtain the specific information you need. In other cases, secondary data may be sufficient.

Expenditure is divided by total GDP at market price multiplied by 100.

Real GDP is computed by subtracting the most recent year’s real GDP from the previous year’s real GDP. The difference is then divided by the previous year’s actual GDP. Real GDP may also be calculated if nominal GDP and the current inflation rate are known.

GDP at market value is the total of all expenditures. The GDP market price percentage rate is computed by dividing spending by total GDP at market price and multiplying by 100. GDP may be calculated in three ways: the value added technique, the income approach (how much money is made as revenue from resources utilized to manufacture things), and the expenditures approach (how much is spent on stuff).

We are wondering in how many distinct options there are to choose 4 subjects out of 20;

n = 20

r = 4.

Sequence is not important because the topics can be arranged in any order and still form the same group, hence we must use a combination:

Review the combination's definition:

²⁰C₄ = 20!/4!(20 - 4)!

²⁰C₄ = 20!/4!16!

You would compare the proportion of simulated samples with a proportion as extreme or more extreme than your sample proportion to estimate the p-value.

For one repetition of a simulation of the proportion of high school students who followed the Egyptian Revolution using blue and yellow poker chips, you would first need to determine the total number of high school students in your sample and the estimated proportion of them who followed the Egyptian Revolution.

Next, assign one color of poker chip (e.g. blue) to represent students who followed the revolution and the other color (e.g. yellow) to represent students who did not.

Then, mix the chips thoroughly and draw a sample of the specified size.

Count the number of blue chips in the sample and divide by the total sample size to calculate the proportion of students who followed the revolution in your sample.

Repeat this process several times to simulate multiple samples from the same population.

To estimate the p-value, you would need to compare the proportion of students who followed the revolution in your sample to the null hypothesis value.

If your null hypothesis is that the true proportion of students who followed the revolution is equal to some hypothesized value (e.g. 0.5), then you would calculate the probability of observing a proportion as extreme or more extreme than your sample proportion, assuming the null hypothesis is true.

To do this, you would need to calculate the difference between your sample proportion and the hypothesized value, divide this by the standard error of the proportion, and then look up this calculated value in a t-distribution table with n-1 degrees of freedom (where n is the number of samples you simulated).

The p-value would be the area under the curve of the t-distribution beyond the calculated value.

Alternatively, you could simulate a large number of samples from a null distribution assuming the hypothesized value for the proportion of students who followed the revolution.

Then, you would compare the proportion of simulated samples with a proportion as extreme or more extreme than your sample proportion to estimate the p-value.
