Answer:

4 km -> 400,000 mm

put a decimal point at the end of 4 and move it to the left 6 times because we know that 1 km is equal to 100,000 and it has zeros.

hence, it is proven that 4 km is equal to 4000,000.

Step-by-step explanation:

first of all, the first sign in the designations of the triangles is not an A. it is the Greek Delta (capital) sign. standing for "triangle" due to its shape.

as the diagram shows (and the description says correctly), ADL and AKM are similar triangles.

that means they have the same angles.

and in order to keep the same angles even when the lengths of the sides are different, the relative relation of the side lengths must be the same for all sides.

that means, if one side changes by a factor f, then both other sides must change by the same factor.

so, by checking the change factor for AD (to AK), we can then determine the change of AL to AM. and then we simply subtract AL from AM and get LM.

the original AD = 14.

AK = AD + DK = 14 + 21 = 35

the change factor f is then AK/AD = 35/14 = 5/2

in other words AD grew by a factor of 5/2.

AM is then created by applying the same factor to AL.

=> AM = 15 * 5 / 2 = 75 / 2 = 37.5

=> LM = AM - AL = 37.5 - 15 = 22.5

Research studies have shown that the estimated return to education does depend positively on parent education.

This means that children who have parents with higher levels of education are more likely to benefit from higher levels of education themselves. The null hypothesis that the return to education does not depend on parent education would be rejected based on this evidence.

It is important to note that there may be other factors that influence the return to education as well, but parent education is a significant predictor. This highlights the importance of parent education and its potential impact on the educational attainment and future success of their children.

Therefore, it is crucial to invest in parent education programs to improve the outcomes of future generations. To test the null hypothesis that the return to education does not depend on parent education, you can follow these steps:

1. Define your variables: Let 'y' be the estimated return to education, 'x1' be the individual's education, and 'x2' be the parent's education. 2. Formulate the null hypothesis (H0) and alternative hypothesis (H1): H0: The return to education does not depend on parent education (i.e., there is no relationship between 'y' and 'x2'),,

H1: The return to education depends positively on parent education (i.e., there is a positive relationship between 'y' and 'x2'). 3. Choose an appropriate test statistic and significance level (α): For example, you can use a linear regression analysis with a significance level of α = 0.05.

4. Collect data: Gather a sample of individuals with information on their return to education, their education level, and their parent's education level.

5. Perform the linear regression analysis: Conduct the analysis with 'y' as the dependent variable and both 'x1' and 'x2' as independent variables. This will provide you with the coefficients for the individual's education (β1) and parent's education (β2).

6. Test the null hypothesis: Check the p-value associated with the coefficient for parent's education (β2). If the p-value is less than the chosen significance level (α = 0.05), you can reject the null hypothesis and conclude that the return to education depends positively on parent education.

Remember that these steps assume you have access to a dataset with the relevant information to conduct this analysis. Once the analysis is complete, you can draw conclusions based on the results.

Bryant Industries uses forecasting to estimate the number of orders that will be placed by their customers. The table below gives the sales figures for the last four months.Month2345Sales92491942004There are different forecasting techniques used by companies like Bryant Industries to predict future sales.

One of the most widely used methods is the time-series method. This method is particularly useful when the demand for a product or service changes over time and when there are no external factors that affect the sales. In this case, we can use a time-series method called the moving average to estimate future sales. The moving average is a time-series method that uses the average of past sales data to estimate future sales. It is particularly useful when there are no external factors that affect the sales. In this case, we can use a 3-month moving average to estimate future sales. The 3-month moving average is calculated as follows: (924 + 919 + 420) / 3 = 754.33. This means that we can expect sales of around 754 units next month. The moving average method is easy to use and is a good way to get a quick estimate of future sales. However, it has some limitations. For example, it does not take into account external factors that may affect sales, such as changes in the economy or in consumer behavior.

In conclusion, Bryant Industries can use the moving average method to estimate future sales. However, they should also consider other factors that may affect sales, such as changes in the economy or in consumer behavior. By doing so, they can make more accurate forecasts and improve their overall performance.

Answer:

ik this alr up here, but the answer is 0.714286

Step-by-step explanation:

Here's why:

First, im put the problem up first.

(5/7)^10 · 1.4^9

Then ima multiply (5/7) 10 times and keep 1.4^9 and here's why

if you don't multiply the exponent your answer will be wrong and you will be confused. So always use the exponent to simplify your answer. if you do 1.4^9 already. you will not find the right answer to simplify. so don't do yet,because that's on the next step

so here's what i got

5/7=9765625/282475249(1.4^9)

Then i will multiply 1.4 9 times in order to find the answer

1.4^9=20.661047

So now we will do the rest

9765625/282475249 (20.661047)

the answer is 0.714286

When q = -17, the value of the equation, q - 7 would be: d. -24.

If we are given an equation to evaluate for a given value of a variable, we are to substitute the value of the variable into the equation and solve or simplify.

For example, if an equation is given as 3x + 4, and we are told that the x = 3, to determine the value of the equation, 3x + 4, substitute x = 3 into the equation as:

3(3) + 4

= 9 + 4

= 13

Here, we can now conclude that the value of the equation is 13.

Given the equation, q - 7, to find the value of the equation when q = -17, substitute the value of q into q - 7.

The 90% confidence interval for the difference in mileage between Brand A and Brand B is approximately (-3,221.62, -978.38) kilometers.

To compute a 90% confidence interval for the difference in mileage between Brand A (HA) and Brand B (Hg), we can use the two-sample t-test formula:

CI = (X₁ - X₂) ± t × √((S₁²/n₁) + (S₂²/n₂))

Where:

X₁ and X₂ are the sample means of Brand A and Brand B, respectively.

S₁ and S₂ are the sample standard deviations of Brand A and Brand B, respectively.

n₁ and n₂ are the sample sizes of Brand A and Brand B, respectively.

t is the critical value from the t-distribution for a 90% confidence interval with (n₁ + n₂ - 2) degrees of freedom.

Given the following information:

Brand A:

X₁ = 35,000 kilometers

S₁ = 4,900 kilometers

n₁ = 14

Brand B:

X₂ = 37,100 kilometers

S₂ = 6,100 kilometers

n₂ = 14

We need to find the critical value for a 90% confidence interval with (n₁ + n₂ - 2) = 26 degrees of freedom. Let's assume you have the necessary table of critical values for the t-distribution.

Assuming you find the critical value to be t = 1.706 (rounded to three decimal places), we can calculate the confidence interval:

CI = (35,000 - 37,100) ± 1.706 × √((4,900²/14) + (6,100²/14))

CI = -2,100 ± 1.706 × √(2,352,100/14 + 3,721,000/14)

CI = -2,100 ± 1.706 × √(167,293.99 + 265,785.71)

CI = -2,100 ± 1.706 × √(433,079.70)

CI = -2,100 ± 1.706 × 657.96

CI = -2,100 ± 1,121.62

CI ≈ (-3,221.62, -978.38)

Therefore, the 90% confidence interval for the difference in mileage between Brand A and Brand B is approximately (-3,221.62, -978.38) kilometers.

The probability of getting a marble marked with a number greater than 4 is \(\frac{1}{9}\).

Probability is the measure of happening or non-happening of outcomes of random experiment.

P(E) = Number of favorable outcomes/Total number of outcomes

where,

P(E) is the probability of an event.

According to the given question.

Total number of marbles in jar = 18

⇒ Total number of outcomes = 18  

( 6 red marbles, 6 black marbles, and 6 green marbles)

But it is given that, black or red marble is randomly selected.

Therefore, the total number of outcomes reduced to 12.

Numbers which are greater than 4 among 1 to 6 are 5 and 6.

Total number of numbers which are greater than 4 in jar = 2 × 3 =6

But we have to select only black or red marble.

Therefore,

Total number of favorable outcomes = 4

The probability of selecting a marble greater than 4 which are red

= \(\frac{4}{12} =\frac{1}{3}\)

The probability of selecting a marble greater than 4 which are black

= \(\frac{4}{12} = \frac{1}{3}\)

Therefore, the probability of getting a marble marked with a number greater than 4 \(=(\frac{1}{3}) (\frac{1}{3} )=\frac{1}{9}\)

Hence, the probability of getting a marble marked with a number greater than 4 is \(\frac{1}{9}\).

The conclusion of hypothesis testing through the t-test is that the technical engineer have not statistically significant evidence to present to the university budget committee to purchase Krapple because it has, on average, a longer battery life. The p-value for t-test is equals to the 0.0074.

We have study related to battery life of two different laptops for student usage at a community college in california. There are two models, Krapple and Madroid. Engineer randomly assigned students to one of the laptop models and recorded the number of minutes the students were able to use the computer until the battery ran out. Here we have paired data so paired t test should be used.

Let d = Krapple - Madroid ( Sample sum of difference). Above table shows the calculations, Sample size, n = 15

Sample sum of difference, d = 1243

Sample mean of differences: Σα

= 1243/15 = 82.87

Sample standard deviation = \(\sqrt{\frac{488317.73}{15-1}}\)

= 186.76

The Null and alternative Hypotheses are defined as \(H_0 : \mu_1- \mu_2 = 0\)

\(H_a : \mu_1 - \mu_2 < 0\)

Level of significance, α = 0.05

Test is one tailed (right tailed) df = n- 1

=> Degree of freedom = 14

Using the t - test, \(t = \frac{\sum d }{ \sqrt{\frac{n\sum d² - (\sum d)²}{n - 1}}}\)

so, \( t = \frac{ 1243}{\sqrt{\frac{15× 488317.73 - (1243)²}{ 15 -1}}}\)

=> \(t =\frac{1243}{\sqrt{412836.925}}\)

=> t = 1.93

Now, using distribution table, P- value for t = 1.93, is 0.074. See, p-value > 0.05 , so result is not statistically significant. So, there is no evidence to reject the null hypothesis.

Conclusion: The technical engineer do not have statistically significant evidence to present to the university budget committee to purchase Krapple because it has, on average, a longer battery life.
