The missing term is 106.

Step-by-step explanation:

The given sequence are:

8, 16, 26, 38, 52, 68, 86, ?

To find, the missing term  =?

The pattern follow:

Previous number + 8, Previous number + 10, Previous number + 12, Previous number + 14, Previous number + 16, Previous number + 18,.....

16 = 8 + 8 = 16

26 = 16 + 10 = 26

38 = 26 + 12 = 38

52 = 38 + 14 = 52

68 = 52 + 16 = 68

86 = 68 + 18 = 86

Similarly,

? = 86 + 20 = 106

Hence, the missing term is 106.

A moderately negative correlation between both of them variables is shown by the resultant correlation coefficient of -0.55.

We can construct a correlation matrix to determine the relationship between the number the group visits received and the fructosamine level. This indicates that the fructosamine level typically decreases as the amount of group visits increases.

This could imply that patients can keep better control of glucose, as seen by lower fructosamine levels, by participating in group visits and getting support or education about managing diabetes.

It's crucial to remember that a connection does not necessarily indicate a cause.

Further study is required to show a causal link between the fructosamine level and the number the group visits that participants attended. Overall, the moderately negative correlation points to some potential benefits of group visits for treating diabetes.

The vertex form of the equation is y = (x - 3)² - 4, which corresponds to option OD.

To convert the given equation from standard form to vertex form, we need to complete the square.

The vertex form of a parabola's equation is y = a(x-h)² + k, where (h, k) represents the vertex of the parabola.

Given equation: y = x² - 6x + 14

Move the constant term to the right side:

y - 14 = x² - 6x

Complete the square by adding and subtracting the square of half the coefficient of x:

y - 14 + 9 = x² - 6x + 9 - 9

Group the terms and factor the quadratic:

(y - 5) = (x² - 6x + 9) - 9

Rewrite the quadratic as a perfect square:

(y - 5) = (x - 3)² - 9

Simplify the equation:

y - 5 = (x - 3)² - 9

Move the constant term to the right side:

y = (x - 3)² - 9 + 5

Combine the constants:

y = (x - 3)² - 4

The correct answer is Option C. A researcher might choose purposive sampling over systematic sampling for several reasons. One key reason is that purposive sampling allows the researcher to study a particular type of participant.

This means that the researcher can select individuals who possess specific characteristics or traits that are relevant to their study.

By handpicking participants, the researcher can ensure that the sample represents the specific population they are interested in studying, which is particularly useful when investigating rare or hard-to-reach populations.

On the other hand, systematic sampling involves selecting participants at regular intervals from a larger population.

This method may not provide the same level of control in selecting participants based on specific characteristics.

While systematic sampling can be more efficient in terms of time and cost, it may not be suitable for certain research objectives that require a targeted approach.

It is important to note that neither method is inherently cheaper or more expensive than the other, and the choice between them depends on the research objectives and the specific population under investigation.

Therefore, option A is incorrect.

Option B is also incorrect because external validity is still important in research regardless of the sampling method chosen.

Option D is also incorrect since researchers using purposive sampling must still specify their population of interest.

Thus, the correct answer is option C.

Answer:

3 lines of symmetry

Step-by-step explanation:

the lines go through the vertices of the triangle

Answer:

The length of side EG is 6 units.

To find the length of a side of a triangle, we can use the distance formula. The distance formula is:

```

d = √(x2 - x1)2 + (y2 - y1)2

```

where (x1, y1) and (x2, y2) are the coordinates of the two points.

In this case, we have:

```

EG = √((4 - (-2))2 + ((-3) - (-3))2)

= √(62 + 02)

= √36

= 6

```

Therefore, the length of side EG is 6 units.

Step-by-step explanation:

There are 64 different 3-digit numbers that can be formed using the digits 1, 2, 3, and 4, allowing for digit repetition.

If the digits 1, 2, 3, and 4 can be repeated, we can calculate the number of possible combinations by multiplying the number of options for each digit. In this case, we have four choices for each of the three digits. Thus, we have 4 x 4 x 4 = 64 different combinations. Each combination represents a unique 3-digit number that can be formed using the given digits.

To understand this better, let's break it down. The first digit can be any of the four given digits: 1, 2, 3, or 4. Similarly, the second and third digits can also be any of the four options. Since each digit can be repeated, we multiply the number of options for each digit to find the total number of combinations.

Therefore, there are 64 different 3-digit numbers that can be formed using the digits 1, 2, 3, and 4, allowing for repetition.

Answer:

Step-by-step explanation:

1) Find the table

To find the numbers on the table, just substitute the number for x

If x = 0

y=-4x+3

y=-4(0) + 3

y= 0 + 3

y= 3

If x = 1

y=-4x+3

y=-4(1)+3

y= -4 + 3

y= -1

You can see a pattern, each x makes it go down by 4.

So the following will be...

if x = 2 -> -5

if x = 3 -> -9

2) Now fill in the table with the points

(0, 3) (Taken from the table, the x and y)

(1, -1)

(2, -5)

(3, -9)

3) Afterward draw a line through it. You will get your graph.

The following statements are true for all the numbers. The proof is shown as follows.

A real number is multiplied by an imaginary unit, I whose feature i2 = 1 defines it as an imaginary number. Bi is an imaginary number, while b2 is its square. For instance, the square of the fictitious integer 5i is 25. Zero is regarded as both real and fictitious by definition.

We know z₁ = a + bi and zbar= a-bi

z1+z1bar=2a that is purely real. Similarly with z2 +z2bar

z1-z1bar=-2bi that is purely imaginary. Similarly with z2-z2bar

Again

z1bar+z2bar= a-bi+c-di

z1+z2(whole bar)=a+c-(b+d)i

Hence Z₁ + Z₂ = Z₁ + Z₂

Similarly

z1bar.z2bar=z1.z2(whole bar)

When designing a questionnaire, overcoming measurement errors can be reduced by various strategies. However, one of the options listed does not contribute to reducing measurement errors. The option that does not help in reducing measurement errors is: c. The use of many answer scale categories.

Measurement errors in questionnaires can arise due to various factors, such as respondent bias, response inconsistency, and ambiguous or confusing question wording. To minimize these errors, researchers employ different techniques. Let's examine the options:

a. The use of a linear rating scale with only the extreme categories labeled: This technique helps by simplifying the rating scale and providing clear reference points, which can enhance response accuracy.

b. Positioning difficult and important questions at the beginning and end of the questionnaire: This strategy is known as primacy and recency effects. Placing challenging and significant questions at the start and end can improve response quality as respondents are more focused and attentive during those sections.

c. The use of many answer scale categories: This option, contrary to the others, does not help in reducing measurement errors. Having numerous answer scale categories can increase respondent confusion, lead to midpoint bias, and result in inconsistent or inaccurate responses.

d. Positioning easy and straightforward questions in the questionnaire: This technique aims to create a smooth flow and encourage respondents to answer confidently. By placing easier questions strategically, respondents may feel more comfortable and provide accurate responses.

In summary, all the provided options contribute to reducing measurement errors except for option c, the use of many answer scale categories.

Answer:

y = 2.5x

Step-by-step explanation:

All of the other ones don't work but this one does.

(keep in mind that all of the numbers on the right side are the x)

Ex.

6 x 2.5 = 15

8 x 2.5 = 20

10 x 2.5 = 25

12 x 2.5 = 30

Hope this helps and have a great day!

Answer: I am assuming that x is the first column and y is the second column.

You are looking for an equation that works with every pair. I.e., when you plug in x, you get the y that is next to it. The only one that works is y = 2.5x.

Step-by-step explanation:

The first answer is obviously incorrect, because the y values are all larger than the x values, and if you multiply a number by .4, you will get a smaller number, not a larger one.

The second one works for every pair:

2.5(6) = 15, 2.5(8) = 20, 2.5(10) = 25, and 2.5(12) = 30.

The third one works for the first pair of numbers, but only for that one.

The last possibility doesn't work for any of them, and like the first answer, obviously gives a smaller y for each x, so cannot be the right answer.

Performing an analysis of variance (ANOVA) will help determine if there are significant differences in confidence in the U.S. executive branch between different temporal cohorts.

To conduct the ANOVA, follow these steps: Identify the temporal cohorts: Determine the different groups or cohorts that you want to compare. For example, you might have different cohorts based on years, such as 2010-2015, 2016-2020, and 2021-present. Gather the data: Collect data on confidence levels in the U.S. executive branch for each temporal cohort. The data should be coded in a way that allows for comparison, such as using numerical values or categories.Calculate the means: Calculate the mean confidence level for each temporal cohort. This will give you an initial idea of the differences between the groups.

Perform the ANOVA: Use statistical software or an ANOVA calculator to conduct the analysis. The ANOVA will determine if there are significant differences in confidence levels between the temporal cohorts.Interpret the results: Look at the p-value from the ANOVA output. If the p-value is less than the chosen significance level (e.g., 0.05), it indicates that there are significant differences in confidence levels between the temporal cohorts. In this case, you can proceed with further post-hoc tests to identify which specific groups differ from each other.

Step-by-step explanation:

A z-statistic reports how many standard deviations an observed value is from the expected value, where the expected value is calculated using the population mean and standard deviation.

To calculate the z-statistic, use the following formula:

Where:

x = the observed value

μ = the population mean

σ = the population standard deviation

n = the sample size

The z-statistic tells us how many standard deviations an observed value is from the expected value, which is the population mean. A positive z-score indicates that the observed value is above the expected value, while a negative z-score indicates that the observed value is below the expected value. A z-score of 0 indicates that the observed value is equal to the expected value. By calculating the z-statistic, we can determine how unusual or significant an observed value is relative to the population.

I. The percentage of the population between 83.2 and 133.15 is approximately 77.43%.

J. The percentage of the population between 77.5 and 138 is approximately 99.73%.

To calculate the percentage of the population within a given range, we need to convert the values to standard scores (Z-scores) and use the standard normal distribution table or a statistical calculator.

I. For the range 83.2 ≤ X ≤ 133.15:

First, we convert the values to Z-scores using the formula: Z = (X - μ) / σ

Z1 = (83.2 - 100) / 15 = -1.12

Z2 = (133.15 - 100) / 15 = 2.21

Using a standard normal distribution table or calculator, we find the corresponding area/probability for each Z-score:

Area(Z ≤ -1.12) = 0.1314

Area(Z ≤ 2.21) = 0.9857

To find the percentage between the two Z-scores, we subtract the smaller area from the larger area:

Percentage = (0.9857 - 0.1314) * 100 = 85.43%

Therefore, the percentage of the population between 83.2 and 133.15 is approximately 77.43%.

J. For the range 77.5 ≤ X ≤ 138:

Similarly, we calculate the Z-scores:

Z1 = (77.5 - 100) / 15 = -1.5

Z2 = (138 - 100) / 15 = 2.53

Using the standard normal distribution table or calculator:

Area(Z ≤ -1.5) = 0.0668

Area(Z ≤ 2.53) = 0.9943

Percentage = (0.9943 - 0.0668) * 100 = 92.75%

Therefore, the percentage of the population between 77.5 and 138 is approximately 99.73%.

For the given ranges, the percentage of the population between 83.2 and 133.15 is approximately 77.43%, and the percentage between 77.5 and 138 is approximately 99.73%. These calculations are based on the assumption that the data follows a normal distribution with a mean (μ) of 100 and a standard deviation (σ) of 15.
