Answer:

problem 1. 53/20 problem 2. 24/27. Problem 3. 22/48

Step-by-step explanation:

to solve the first two, the process is similar. For the first one, they can be simplifed back into fraction form and not mixed form, so 1 2/5 can be simplified by multiplying 5 by one then adding it to 2, which gives you 7/5, and the same process for 2 1/2, multiply 2 by two, get 4 add it to one to get 5/2. Now we have 7/5 + 5/2, when we have fractions that we need to add or subtract, but down have the same bottom number, the easiest way to get a answer is to multiply both bottom numbers together then multiply the top number by the opposite bottom number, so 5x4 = 20, 4x7=28, 5x5=25, and we get 28/20 + 25/20 = 53/20. The process for problem two is the same, but just with subtraction and different numbers.

for problem three, the process is almost the same, but the steps differ. The bag is made up of R G and P counters, 3/8 of them are red, 1/6 are green, and the rest are purple because nothing else is in the bag. So another way of saying this is 3/8 + 1/6 + purple = Full Amount in bag. But now we need purple, so we know 1/2 one half and so does 2/4, and since we have fractions we can find the amount in the bag by adding them, 3/8 + 1/6 = 26/48, and we know the full bag is 1/1 or 48/48, and fhe only one left is purple, so to get purple, we subtract 48/48 from 26/48 and get 22/48 which is the amount of purple.

The approximation of Az using the total differential dz is Az ≈ 2021.4.

To find f(10, 6), we plug in x = 10 and y = 6 into the given function:

f(10, 6) = 10 cos(6) ≈ 9.6017

To find f(10.1, 6.05), we plug in x = 10.1 and y = 6.05 into the given function:

f(10.1, 6.05) = 10.1 cos(6.05) ≈ 9.8266

To calculate Az, we use the formula:

Az = [(f(10.1, 6.05) - f(10, 6)) / f(10, 6)] × 10000

Plugging in the values we found above, we get:

Az = [(9.8266 - 9.6017) / 9.6017] × 10000 ≈ -2245

To use the total differential dz to approximate Az, we use the formula:

dz = ∂f/∂x dx + ∂f/∂y dy

where ∂f/∂x and ∂f/∂y are the partial derivatives of f with respect to x and y, respectively. We evaluate these partial derivatives at (10, 6) and use dx = 0.1 and dy = 0.05 (the changes in x and y values from (10, 6) to (10.1, 6.05)):

∂f/∂x = cos(y) ≈ -0.2794

∂f/∂y = -x sin(y) ≈ -5.3211

So,

dz = (-0.2794)(0.1) + (-5.3211)(0.05) ≈ 0.1942

To approximate Az using dz, we use the formula:

Az ≈ (dz / f(10, 6)) × 10000

Plugging in the values we found above, we get:

Az ≈ (0.1942 / 9.6017) × 10000 ≈ 2021.4

Therefore, the approximation of Az using the total differential dz is Az ≈ 2021.4.

Since η² ≈ 0.33 and not 0.50, the statement "If an analysis of variance produces SS between = 20 and SS within = 40, then η² = 0.50" is false.

ANOVA, or Analysis of Variance, is a statistical method used to compare the means of two or more groups to determine if there are any statistically significant differences between them. It is commonly used in experimental and observational studies to analyze the variance between group means and within-group variability.

ANOVA tests the null hypothesis that the means of the groups are equal, against the alternative hypothesis that at least one of the group means is different. It calculates the F-statistic, which compares the between-group variability to the within-group variability. If the F-statistic is large enough and exceeds a critical value, it indicates that there is evidence to reject the null hypothesis and conclude that there are significant differences between the group means.

We can determine if η² = 0.50 is true or false by calculating the effect size η² using the provided SS between and SS within values.
η² = SS_between / (SS_between + SS_within)
η² = 20 / (20 + 40)
η² = 20 / 60

True, the eta-squared value is indeed 0.50, indicating that 50% of the total variance is accounted for by the between-group variation.

The formula to calculate eta squared (η2) is:
η2 = SSbetween / (SSbetween + SSwithin)
If SSbetween = 20 and SSwithin = 40, then:
η2 = 20 / (20 + 40) = 0.5
Therefore, η2 = 0.50, which means that 50% of the total variance in the dependent variable can be attributed to the independent variable (or factor) being analyze. The statement "If an analysis of variance produces SS between = 20 and SS within = 40, then η 2 = 0.50" is true. To determine η 2 (eta-squared), you'll need to calculate the proportion of total variance explained by the between-group variation. This can be done using the formula η 2 = SS between / (SS between + SS within). In this case, η 2 = 20 / (20 + 40) = 20 / 60 = 0.50. Therefore, the eta-squared value is indeed 0.50, indicating that 50% of the total variance is accounted for by the between-group variation.

Four siblings whose ages are consecutive odd integers. If the sum of their ages is 112 then The eldest sibling is 31, followed by siblings 29, 27, and 25.

What is consecutive integers ?

Consecutive means in order.  Integers are a collection of whole integers and their antipodes, such as -3, -2, 1, 0, 1, 2, 3, etc.

Let x = the 1st sibling

Let x -2 = the second sibling

Let x -4 = the third sibling

Let x-6 = the fourth sibling.

If you add the four siblings together they equal 112

(x) +(x-2)+(x-4)+(x-6) = 112  Combine like terms

4x - 12 = 112

add 12 from both sides

4x - 12 + 12 = 112 + 12

The perimeter of triangle ∆XYZ must measure 135 units, while its area amounts to 600 square units.

Since ∆ABC possesses side lengths of 10 units, 20 units, and 24 units, and ∆XYZ is similar to ∆ABC but with the length of its longest side being 60 units, we can apply the principle of similarity to determine the perimeter and area of ∆XYZ.

The perimeter of ∆XYZ:

To find the scale factor between two similar triangles, you can take the ratio of the corresponding sides. In this case, the longest side of ∆ABC is 24 units, and the longest side of ∆XYZ is 60 units.

Scale factor = (Longest side of ∆XYZ) / (Longest side of ∆ABC)

Scale factor = 60 / 24

Scale factor = 2.5

Now, we can determine the other two sides of ∆XYZ using the same scale factor:

The shortest side of the ∆XYZ = (Scale Factor * Shortest side of ∆ABC)

The shortest side of the ∆XYZ = ((5/2) * 10 units)
                                            = 25 units

Middle side of ∆XYZ = Scale Factor * Middle side of ∆ABC

Middle side of ∆XYZ = (5/2) * 20 units
                                     = 50 units

Now, calculate the perimeter of ∆XYZ:

The perimeter of ∆XYZ = Sum of all three sides

Perimeter of ∆XYZ = 60 units + 25 units + 50 units
                               = 135 units

Therefore, the perimeter of ∆XYZ is 135 units.

Area of ∆XYZ:

Because ∆XYZ and ∆ABC are similar, their corresponding side ratios are equal to the scale factor, which is 5/2.

Now,

Given the triangle ∆XYZ, it is established that the ratio of their areas is equivalent to the square of the scale factor when determining the area.

Area of ∆XYZ / Area of ∆ABC = (Scale Factor)²

Area of ∆XYZ / Area of ∆ABC = (5/2)²

Area of ∆XYZ / Area of ∆ABC = 25/4

Since we're given the height of ∆ABC with respect to its longest side, we can find the area of ∆ABC:

Area of ∆ABC = (1/2) * Base * Height

Area of ∆ABC = (1/2) * 24 units * 8 units
                       = 96 square units

Now, calculate the area of ∆XYZ:

Area of ∆XYZ = (Area of ∆ABC) * (Area ratio)

Area of ∆XYZ = 96 square units * 25/4

Area of ∆XYZ = 600 square units

Therefore, the area of ∆XYZ is 600 square units.

Answer:

x =4

Step-by-step explanation:

First we need to find the length of RT

Since the triangle on the left (RST) is a right triangle, we can use trig functions

sin theta = opp / hyp

sin 60 = 2 sqrt(3) / RT

RT sin 60 = 2 sqrt(3)

RT = 2 sqrt(3) / sin 60

RT = 2 sqrt(3) / (sqrt(3)/2)

RT = 4

Now we can find x

Since the triangle on the right (QRT) is a right triangle, we can use trig functions

tan theta = opp /adj

tan 45 =  x/ RT

tan 45 = x / 4

4 tan 45 = x

4 (1) = x

The correct option is 20.

The score found for the sample is 20.

A standard error is a statistic that is applied to test the distribution of data. This metric is comparable to standard deviation. We can calculate the standard error if we know the sample size & standard deviation. It assesses the mean's precision.

Now, according to the question;

Sample mean; \(\bar{x}=40\)

Sample variance; \(s^{2}=20\)

Thus, \(s=\sqrt{20}=4.47\)

Standard error SE = 1

The amount of scores with in sample must be determined here.

The standard error formula is as follows:

\(S E=\frac{s}{\sqrt{n}}\)

We might rearrange the formula as follows:

\(\begin{aligned}\sqrt{n} &=\frac{s}{S E} \\n &=\left(\frac{s}{S E}\right)^{2}\end{aligned}\)

Substituting the values;

\(\begin{aligned}&n=\left(\frac{4.47}{1}\right)^{2} \\&n=19.98\end{aligned}\)
