It is true that when constructing a table with metric variables, you should absolutely include the average(s).

When constructing a table with metric variables, it is important to include the measures of central tendency such as the mean, median, and mode. The average or mean is particularly important as it provides a summary measure of the data set and is often used as a benchmark for comparison with other values. By including the average, the table can convey information about the typical or expected value of the metric variable.

The mean, or average, is a commonly used measure of central tendency. It is calculated by summing all of the values in the data set and dividing by the number of observations. The mean is useful because it is sensitive to all of the values in the data set and provides a benchmark for comparison with other values.

The study provides evidence that the type of feed supplement has a significant effect on the growth rate of chickens, and some feed supplements are more effective than others in promoting growth.

The experiment aimed to compare the effectiveness of different feed supplements on the growth rate of chickens. Newly hatched chicks were randomly assigned to six groups, each receiving a different feed supplement. The study recorded the weight of the chicks, and sample statistics and a visualization of the observed data were presented.

The hypothesis test conducted aimed to determine if there was sufficient evidence to conclude that the average weight of chicks varies across some or all groups. The null hypothesis assumes that there is no difference in the average weight of chicks on different diets, while the alternative hypothesis assumes that there is a difference.

To test the hypothesis, we need to check if the conditions for the ANOVA test are met. First, we need to assume that the population variances are equal across all groups, which we can verify by checking if the standard deviations of the groups are roughly equal.

In this case, the standard deviations range from 38.63 to 64.90, indicating that the assumption of equal variances may not be reasonable. However, we will still proceed with the ANOVA test, as the sample sizes are roughly equal and the assumption of equal variances is not critical when the sample sizes are equal.

Next, we can calculate the F-statistic by dividing the mean square between groups by the mean square within groups. The F-statistic is 15.4, with a p-value of less than 0.0001, indicating strong evidence against the null hypothesis.

Therefore, we can conclude that there is convincing evidence that the average weight of chicks varies across some or all groups.

To determine which groups differ significantly, we can perform post-hoc tests, such as Tukey's HSD test. These tests can identify which pairs of groups have significantly different mean weights.

Overall, the study provides evidence that the type of feed supplement has a significant effect on the growth rate of chickens, and some feed supplements are more effective than others in promoting growth.

[tex]\\\cos B =\dfrac{8\sqrt{79}}{79}[/tex]

Step-by-step explanation:

How do we find cosine of an angle in a right triangle?
In a right-angled triangle, if one of the angles is θ, then the cosine of θ is the length of the side adjacent to θ, divided by the length of the hypotenuse .

Here we are trying to find cos B

The side adjacent to B is BC with a length of [tex]8[/tex]

The hypotenuse is BD with a length of [tex]\sqrt{79}[/tex]

[tex]\therefore\\\cos B = \dfrac{8}{\sqrt{79}}\\[/tex]

[tex]79[/tex] is a prime number so it cannot be factored

To express in simplest radical form, we have to remove [tex]\sqrt{79}[/tex] from the denominator by  multiplying the numerator and denominator by [tex]\sqrt{79}[/tex]

Since his total earnings are £1072, which is greater than £294.80, we can conclude that Rory's claim is correct.

To see if Rory's assertion is correct, we must compute the mean average of his wages for the last four weeks.

By adding up the earnings for each week, the total earnings over the last four weeks may be calculated:

Total earnings = £307.50 + £235.75 + £287 + x (week 4 earnings)

We know that Rory's wages over the last four weeks should have averaged £268, thus we can solve the following equation:

(£307.50 + £235.75 + £287 + x) / 4 = £268

Simplifying this equation, we get:

£830.25 + x = £1072

x = £1072 - £830.25

x = £241.75

As a result, Rory's earnings for week 4 should be £241.75, for a total of £268 for the last four weeks.

Rory now claims to have earned 10% more than the average over the last four weeks. The average wages over the last four weeks are £268, so 10% extra would be:

£268 + 10% of £268 = £268 + £26.80 = £294.80

Rory's earnings for the last four weeks are as follows: £307.50 + £235.75 + £287 + £241.75 = £1072

To see if he made 10% more than the average, we can take 10% of the average and multiply it by the average to get the expected value:

£268 + 10% of £268 = £268 + £26.80 = £294.80

1. The he intersection points A and B are:

A(-2, -1) and B(6, 7)

2. Midpoint is (7, -1)

3. length of AB is 4√5

To find the intersection points A and B, set y = x + 1 and y = x² - 3x - 11 equal to each other:

x + 1 = x² - 3x - 11

Now, rearrange the equation to set it equal to zero:

x² - 4x - 12 = 0

Factor the quadratic equation:

(x - 6)(x + 2) = 0

Solve for x:

x = 6, x = -2

Now plug the x-values back into the equation of either line (y = x + 1) to find the corresponding y-values:

For x = 6: y = 6 + 1 = 7

For x = -2: y = -2 + 1 = -1

So the intersection points A and B are:

A(-2, -1) and B(6, 7)

a) To find the midpoint of A(5,-5) and B(9,3), use the midpoint formula:

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

Midpoint = ((5 + 9)/2, (-5 + 3)/2) = (14/2, -2/2) = (7, -1)

b) To find the length of AB, use the distance formula:

Distance = √((x2 - x1)² + (y2 - y1)²)

Distance = √((9 - 5)² + (3 - (-5))²) = √(4² + 8²) = √(16 + 64) = √80

Length of AB = 4√5 (simplified

a) To find the length of AB, use the distance formula:

Distance = √((x2 - x1)² + (y2 - y1)²)

Distance = √((9 - 5)² + (-1 - 7)²) = √(4² + (-8)²) = √(16 + 64) = √80

Length of AB = 4√5 (simplified)

b) To find the equation of the line AB, first find the slope:

m = (y2 - y1)/(x2 - x1) = (-1 - 7)/(9 - 5) = (-8)/4 = -2

Next, use the point-slope form with one of the points (A or B), say A(5,7):

y - y1 = m(x - x1)

y - 7 = -2(x - 5)

Now, convert the equation to the slope-intercept form (y = mx + c):

y = -2x + 10 + 7

y = -2x + 17

Devin because the second side length is the square root of 3 times the measure of the smallest side length, and the largest side is twice the smallest side. Glenn's claim is incorrect because his triangle's side lengths do not match the 30-60-90 ratio, unlike Devin's triangle, which satisfies the conditions of a 30-60-90 triangle.

A 30-60-90 triangle has specific side length ratios: the sides opposite the angles measuring 30 degrees, 60 degrees, and 90 degrees are in the ratio 1:√3:2. Let's analyze the claims made by Devin and Glenn:

Devin's claim:

Devin states that a triangle with side lengths of 6, 6√3, and 12 is a 30-60-90 triangle. To verify this, we need to check if the side lengths satisfy the 30-60-90 ratio. If we divide the longest side by 2, we get 12/2 = 6, which matches the length of the shortest side. Also, the middle side (6√3) is indeed √3 times the length of the shortest side (6). Thus, Devin's claim is correct, and the triangle with side lengths 6, 6√3, and 12 is a 30-60-90 triangle.

Glenn's claim:

Glenn states that a triangle with side lengths 7, 7√3, and 49 is a 30-60-90 triangle. Again, we need to check if the side lengths satisfy the 30-60-90 ratio. However, upon examination, we find that dividing the longest side by 2 (49/2) does not result in the length of the shortest side (7). Also, the middle side (7√3) is not √3 times the length of the shortest side (7). Therefore, Glenn's claim is incorrect, and the triangle with side lengths 7, 7√3, and 49 is not a 30-60-90 triangle.

f(-x) = -x⁵ + 3x⁴ + 3x + 7

This shows that f(x) has 2 or 0 negative real zeros

Let's subtract the number of real zeros from degree of f(x) to determine the complex zeros

complex zeros = 5 - 2 = 3

This shows we have 2 positive zeros, 2 negative zeros and 3 complex zeros
