Step-by-step explanation:

The appropriate statistic test should be ANOVA and The degree of freedom is 12.

What are Statistical tests?

An instrument for making quantitative judgments about a process or processes is a statistical test. The goal is to decide whether there is sufficient data to "reject" a theory or hypothesis on the process.

In the given problem the average age of the corporate executives at the three locations is being calculated, it means more than two groups are being compared. hence, The appropriate statistic test would be ANOVA.

In order to calculate the degree of freedom, we must know the no. of observations.

here,  no. of observations are 15 ( 3 × 5 ) and the no. of groups are 3.

∴ Degree of freedom = no. of observations - no. of groups

                                    = 15 - 3 = 12.

Step-by-step explanation:

\(4 \sqrt{7} + 3 \sqrt{28} \\ \\ 4 \sqrt{7} + 3(2 \sqrt{7} ) \\ \\ 4 \sqrt{7} + 6 \sqrt{7} = 10 \sqrt{7} \)

The correct answer is: III only. Variance investigation is typically based on a cost-benefit analysis.

Statement I is incorrect because the relative size of a variance, in comparison to other variances, can be important in understanding its significance.

Statement II is incorrect because variance investigation does not focus solely on unfavorable variances. Both favorable and unfavorable variances are considered during the investigation.

Statement III is true. Variance investigation is typically based on a cost-benefit analysis, where the potential benefits of investigating and addressing variances are weighed against the associated costs.

We can calculate the values of the angles given that the sum of the interior angles is equal to 180 degrees:

With the value of x, we can calculate the value of each of the angles:

As we have 2 equal angles, we can think of the triangle as having a axis of symmetry, bisecting the angle that has a unique value (mC=70 deg).

Then, as we have an axis of symmetry, two of the sides of the triangle are equal.

Then, the triangle is isosceles (Option 3).

Answer:

A) 12

Step-by-step explanation:

3/2=x/8

2x=24

x=12

cos ∠G = (0.3420) sin ∠G + (15.21 - 19.44 cos (180° - ∠F - ∠G)) / 28.475. Since the sum of the angles in a triangle is 180°, we can find the measure of ∠E by subtracting ∠F and ∠G from 180°:

∠E = 180° - ∠F - ∠G

We can then use the Law of Cosines to solve for the length of side e:

e² = f² + g² - 2fg cos ∠E

e² = (3.9)² + (5.6)² - 2(3.9)(5.6)cos ∠E

Next, we can use the Law of Cosines again to solve for the cosine of ∠G:

g² = f² + e² - 2fe cos ∠G

cos ∠G = (f² + e² - g²) / 2fe

cos ∠G = (3.9² + e² - 5.6²) / (2 × 3.9 × e)

cos ∠G = (15.21 + e² - 31.36) / (7.8e)

cos ∠G = (e² - 16.15) / (3.9e)

Now we can substitute the expression for ∠E into the equation, and then use that result to solve for cos ∠G:

e² = (3.9)² + (5.6)² - 2(3.9)(5.6)cos (180° - ∠F - ∠G)

e² = (3.9)² + (5.6)² + 2(3.9)(5.6)cos (∠F + ∠G)

cos (∠F + ∠G) = (e² - 3.9² - 5.6²) / (2 × 3.9 × 5.6)

cos (∠F + ∠G) = (e² - 50.65) / 30.24

Now we can use the identity for the cosine of a sum to solve for cos ∠G:

cos (∠F + ∠G) = cos ∠F cos ∠G - sin ∠F sin ∠G

cos 156° cos ∠G - sin 156° sin ∠G = (e² - 50.65) / 30.24

(0.9397) cos ∠G - (0.3420) sin ∠G = (e² - 50.65) / 30.24

Solving for cos ∠G, we get:

cos ∠G = (0.3420) sin ∠G + (e² - 50.65) / (30.24 × 0.9397)

Substituting the expression for e² from the earlier step, we get:

cos ∠G = (0.3420) sin ∠G + (3.9² + (5.6² - 2(3.9)(5.6) cos (180° - ∠F - ∠G)) - 50.65) / (30.24 × 0.9397)

cos ∠G = (0.3420) sin ∠G + (15.21 - 19.44 cos (180° - ∠F - ∠G)) / 28.475

The  95% confidence that the true proportion of people who favor the tax plan in the town is between 0.314 and 0.366.

A confidence interval is a statistical range of values that is likely to contain an unknown population parameter with a specified level of confidence. In other words, it is a measure of the uncertainty surrounding an estimate of a population parameter, such as the mean or the proportion.

To calculate a confidence interval for the proportion of people who favor the tax plan, we can use the following formula:

CI = p ± zsqrt(p(1-p)/n)

where CI is the confidence interval, p is the sample proportion (i.e., the proportion of respondents in favor of the tax plan), z is the z-score associated with the desired confidence level (in this case, 95%), and n is the sample size.

First, we need to calculate the sample proportion:

p = 663/1950

p ≈ 0.340

Next, we need to find the z-score associated with a 95% confidence level. We can use a standard normal distribution table or calculator to find that the z-score for a 95% confidence level is approximately 1.96.

Now we can plug in the values and calculate the confidence interval:

CI = 0.340 ± 1.96sqrt(0.340(1-0.340)/1950)

CI ≈ 0.314 to 0.366

Therefore, we can say with 95% confidence that the true proportion of people who favor the tax plan in the town is between 0.314 and 0.366.

If the same condition is described as both acute and chronic and separate subentries exist in the icd-10-cm alphabetic index at the same indentation level is True

What is alphabetical index?

An alphabetical index, often known as an index, is a list of words or phrases that appear frequently in a text and which, if listed alphabetically, may assist readers in finding information more quickly.

What is indentation level ?

The much-despised formatting method of indentation gives readers a sense of continuity.

Reasons:

The Alphabetic Index's sub term entries and the Tabular List's inclusion and exclusion notes can both be used to find combination codes.

Only use the combination code when it accurately describes the diagnostic conditions in question or when the Alphabetic Index instructs you to. When the categorization offers a combination code that unambiguously identifies all of the components listed in the diagnosis, multiple coding shouldn't be employed. An additional code should be utilised as a secondary code when the combination code does not provide the requisite specificity in characterising the symptom or problem.

1. Identify the categorical variables and list their possible categories.

cat, no cat, dog, no dog

2. Count the number of observations for each combination of categories.

cat = 17

no dog = 20

no cat no dog = 7

3. Organize the counts in a table with the categories of one variable as rows and the categories of the other variable as columns.

          | dog | no dog | total

cat      |        |              |   17  |

no cat |        |     7       |        |

total    |        |     20    |   41  |
