The depth of the water in the cylinder container is 120.9inches.

Given:

The frustum's vertical depth (h) is 30 cm.

Top frustum radius (r1) = 18 cm

Frustum's bottom radius (r2) is 28 cm.

The following formula determines the volume of a cone's frustum:

[tex]V = \frac{1}{3}* \pi * h * (r1^2 + r2^2 + (r1 * r2))[/tex]

calculating the frustum's volume

V=[tex]\frac{1}{3} *\pi *30(18^2+28^2+18*28)\\[/tex]

V=50642.5[tex]in^3[/tex].

The following formula determines a cylinder's volume:

Volume of cylinder = [tex]\frac{1}{3} \pi r^2h[/tex]

[tex]50642.5 = (1/3) *\pi *20^2*h[/tex]

h=[tex]50642.5*\frac{3}{\pi *20^2}[/tex]

Manova (Multivariate Analysis of Variance) tests whether mean differences among groups on a combination of dependent variables (DVs) are statistically significant. If there is at least 20 cases in the smallest cell, the test is robust to violations of the assumption of multivariate normality.

In Manova, multiple dependent variables are analyzed simultaneously to determine if there are significant differences among groups. The test examines whether the mean vectors of the groups are equal across the DVs. The assumption of multivariate normality implies that the data should follow a multivariate normal distribution.

Some alkenes have geometric cis-trans isomers because of the presence of a double bond between two carbon atoms. In a carbon-carbon double bond, the carbon atoms are connected to two different groups of atoms, which can be oriented differently in space. In the cis configuration, the two substituent groups on each carbon atom are on the same side of the double bond, while in the trans configuration, the two substituent groups on each carbon atom are on opposite sides of the double bond.

The cis-trans isomerism arises due to the restricted rotation around the carbon-carbon double bond. In the case of cis isomers, the substituent groups are too bulky to rotate around the double bond, and they remain on the same side of the double bond. In contrast, in the trans isomers, the substituent groups are oriented on opposite sides of the double bond, which allows them to rotate freely around the bond.

The presence of cis-trans isomers has important consequences for the physical and chemical properties of alkenes, including their reactivity, solubility, and melting points. The two isomers can have different properties and can exhibit different biological activities, making them important targets for drug design and synthesis.

Answer. The correct option is (E). 9.5 and 14.5

Explanation for step 1This is because 95% of the mean weights from samples of size 100 cats from this population will fall between 9.5 and 14.5 pounds. The other answers are incorrect because they do not fall within the range of 95% of the mean weights from samples of size 100 cats from this population

About 95% of the mean weights from samples of size 100 cats from this population would fall between approximately 11.51 pounds and 12.49 pounds.

To determine the range within which 95% of the mean weights from samples of size 100 cats would fall, we can use the concept of the confidence interval.

Given:

Population mean weight (μ) = 12 pounds

Population standard deviation (σ) = 2.5 pounds

Sample size (n) = 100 cats

Since the population distribution is assumed to be approximately normal, the sampling distribution of sample means will also be approximately normal. To calculate the range, we can use the formula for the confidence interval:

Confidence Interval = sample mean ± (z * standard error)

The standard error can be calculated using the formula:

Standard Error = σ / √n

Using a 95% confidence level, the corresponding z-value is approximately 1.96 (obtained from standard normal distribution table).

Plugging in the values:

Standard Error = 2.5 / √100 = 0.25

Confidence Interval = 12 ± (1.96 * 0.25)

Calculating the values:

Lower limit = 12 - (1.96 * 0.25) ≈ 11.51 pounds

Upper limit = 12 + (1.96 * 0.25) ≈ 12.49 pounds

We have,

1.

GCH and ECD are alternate angles.

This means,

GCH = 125 = ECD

And,

ECG and DCH are alternate angles.

This means,

ECG = DCH = x

Now,

GCH + ECD + ECG + DCH = 360

125 + 125 + x + x = 360

250 +2x = 360

2x = 360 - 250

2x = 110

x = 55

Now,

ECG = ECF + FCG

55 = ECF + FCG

ECF and FCG are equal.

So,

m∠FCG = 55/2 = 27.5

2.

The straight angles are formed by (5x + 20) and (2x - 5).

So,

5x + 10 + 2x - 5 = 180

7x + 5 = 180

7x = 180 - 5

7x = 175

x = 25

3.

2x + 43 and 2x - 3 are on the same side of the parallel lines.

So,

2x + 43 + 2x - 3 = 180

4x + 40 = 180

Scatter charts are useful in identifying patterns and relationships between the two variables. The strength and direction of the relationship between the variables can be determined by examining the pattern of the scatter chart. If the data points are tightly clustered around a straight line, then there is a strong linear relationship between the two variables. On the other hand, if the data points are scattered without any pattern, then there is no relationship between the two variables.

A ratio is a comparison of two or more quantities expressed as a fraction. For example, if we say that the ratio of apples to oranges is 2:3, it means that for every two apples, there are three oranges. Ade received an amount of 1500 from the total sum of 4000 .

In order to find out the amount Ade received, we need to first understand the concept of ratio. A ratio is a comparison of two or more quantities expressed as a fraction. For example, if we say that the ratio of apples to oranges is 2:3, it means that for every two apples, there are three oranges.

In this problem, we are given that Ade and Ola share a sum of 4000 in the ratio of 3:5. This means that the total ratio is 3+5 = 8.

To find out the amount Ade received, we need to first find the fraction of the total sum that belongs to Ade. We can do this by dividing Ade's ratio by the total ratio.

Ade's ratio is 3, so the fraction of the total sum that belongs to Ade is 3/8.

Now, we can find the amount Ade received by multiplying this fraction by the total sum:

Amount Ade received = (3/8) x 4000 = 1500.

1.Add the ratio parts: 3 (Ade's part) + 5 (Ola's part) = 8 total parts.

2. Divide the total sum (4000) by the total parts (8): 4000 ÷ 8 = 500. This gives us the value of one part.

3. Multiply Ade's ratio part (3) by the value of one part (500): 3 × 500 = 1500.

So, Ade received an amount of 1500 from the total sum of 4000.

The rule that represents the dilation of the original triangle with a scale factor of 12 centered at the origin is (x, y) → (12x, 12y).

The coordinates of the vertices of the original equilateral triangle can be found by dividing the perimeter by the length of each side, which is 4/3. Thus, each vertex is located at a distance of 4/3 units from the adjacent vertices.

Let's assume that the original triangle is centered at the origin (0,0) and its vertices are (2/3, 0), (-1/3, √3/3), and (-1/3, -√3/3).

Multiply the x and y coordinates of each vertex by the scale factor of 12.

Thus, the vertices of the dilated triangle would be:

(2/3) × 12, 0 × 12 = (8, 0)

(-1/3) × 12, √3/3 × 12 = (-4, 2√3)

(-1/3) × 12, -√3/3 × 12 = (-4, -2√3)

(B(9) - B(2) divided by 7),

the amount of weight Puppy B gained in ounces during the seven-week interval ending at

t=9 (B(9) - B(2)),

Acute Angle - Acute angles are angles that measures less than 90° degrees

Obtuse Angle - Obtuse angles are any angles that greater than 90° with the exception of an 180° angle

Right Angle - Right angles are angles that are exactly equal to 90°

Straight Angle -  Straight angles are defined angles that are exactly 180 ° degrees.

Since a straight angle is 180° degrees. Therefore, this angle would be defined as a straight angle. Hope this helps!
