Answer:

Expression: \(\pi(\frac{D}{2})^{2}h-\pi(\frac{d}{2})^{2}h\)

Volume: \(339.29cm^{3}\)

Step-by-step explanation:

The formula for the volume of a cylinder is: \(\pi r^{2}h\). Since we are given the diameters instead of the radius, we divide the diameters by 2 to get the radius.

∴ The expression for the volume of the large cylinder after the hole was removed is \(\pi (\frac{D}{2})^{2}h - \pi(\frac{d}{2})^{2}h\)

Approximate volume:

Substitute the numbers in:

\(\pi(\frac{8}{2})^{2}\times9-\pi(\frac{4}{2})^{2}\times9=339.29cm^{3}\) (to the second decimal place)

∴ The volume of the big cylinder after removing the cylindrical hole is approximately \(339.29cm^{3}\)

Answer:

AZ = 12.80

Step-by-step explanation:

There are 2 triangles in the square XARS. Squares are always congruent, all sides are the same. Given that WT is 6, we can assume that RS is also 6 (because of congruency). RA is is the hypotenuse of the triangle ARS. To find AS, we can plug in the pythagorean theorem 6^2+x=^2=10^2. We end up getting square root of 64 which simplifies to 8. AS is now 8. We also know that ST is 6 since the square WRST has all congruent sides. 8+6=14 gives us line AT. TZ is 8 due to triangle XAR and the congruency theorem. Now we plug in pythagorean theorem to find AZ and we get 8^2+10^2=x^2. After simplifying the square root of 164, we see that AZ is equal to 12.80

How might snakes running out of food affect other organisms such as hawks? please help

Answers

Answer:

The population of Hawks and other species would likely start to edge off.

Step-by-step explanation:

Commonly, a Food Chain is dependent on all the parts of it sataying at a perfect point. If the food that the Snakes eat starts to run out, more of them will die off. With less Snakes, the Hawks will then have less food, and that continues throughout the chain. The same thing would happen if there was too much food, except instead of the populations of species dying off, the Snake population would spike.

the null hypothesis for anova posits no difference among population means, as in other hypothesis tests, but the research hypothesis in this case is a bit different. why?

Answers

Because it involves the comparison of means across three or more groups or populations rather than just two.

Why the research hypothesis is different?

In anova, the null hypothesis posits that there is no difference among the population means of the groups being compared, while the research hypothesis proposes that at least one of the population means is different from the others.

This is because anova is typically used when there are multiple groups or treatments being compared, and the research question of interest is whether there is a significant difference in the means of these groups. Therefore, the research hypothesis in ANOVA is concerned with differences between multiple means rather than just two, as in other hypothesis tests such as the t-test.

Answers

The volume of the cylnder is  9,728.5 ft³

How to find the volume of the cylinder?

For a cylinder of radius R and height H, the volume is given by:

V = pi*R^2*H

Where pi = 3.14

Here we know that the height is.

H = (20 + 1/2) ft = 20.5 ft

And the diameter is (1 + 1/5) times the height, then:

D = (1 + 1/5)*(20 + 1/2) ft = (1.2)*(20.5)ft = 24.6ft

And the radius is half of that, so:

R = 12.3ft

Then the volume is:

V = 3.14*(12.3ft)^2*20.5ft = 9,728.5 ft³

The alternative hypothesis if you are trying to find out if you have enough evidence to conclude that the mean of population 1 exceeds the mean of population 2 would be what?

Answers

If you are trying to find out if you have enough evidence to conclude that the mean of population 1 exceeds the mean of population 2, the alternative hypothesis would be that the mean of population 1 is greater than the mean of population 2. This is because the alternative hypothesis always represents the opposite of the null hypothesis, which in this case would be that the mean of population 1 is not greater than the mean of population 2.

In order to test this hypothesis, you would need to collect data from both populations and use statistical methods to analyze the data. This would involve calculating the sample means and standard deviations, and using techniques such as hypothesis testing and confidence intervals to determine whether there is a significant difference between the two populations.

The evidence you would need to support the alternative hypothesis would depend on the level of significance you choose for your test, as well as the size and variability of the samples. Generally, you would need a large enough sample size and a significant difference in means between the two populations to reject the null hypothesis and conclude that the alternative hypothesis is true.

Overall, the process of testing a hypothesis involves careful planning, data collection and analysis, and interpretation of results. By using sound statistical methods and relying on strong evidence, you can determine whether your hypothesis is supported by the data and draw meaningful conclusions about the populations you are studying.

Two hundred liters of a punch that contains 35% fruit juice is mixed with300 liters of another punch. the resulting fruit punch is 20% fruit juice. find the percent of fruit juice in the 300liters of punch

Answers

If two hundred liters of a punch that contains 35% fruit juice is mixed with 300 liters of another punch and the resulting fruit punch is 20% fruit juice, then the percent of fruit juice in 300 liters of punch is calculated to be 10%.

The percentage of fruit juice in 300 liters of punch can be calculated by forming a linear equation.

A linear equation also termed a first-degree equation is an equation with one or more variables that have the highest power of one.

A linear equation for this problem can be given as:

the volume of the first punch × percentage of fruit juice in the first punch + the volume of the second punch × percentage of fruit juice in the second punch = total volume × total percentage of fruit juice

Consider x = percentage of unknown fruit juice

Now add the given values in the equation:

200 × 35 + 300(x) = 500 × 20

7000 + 300(x) = 10000

300(x) = 10000 - 7000

300(x) = 3000

x = 3000 / 300

x = 10%

Hence, the percentage of fruit juice in 300 liters of punch is calculated to be 10%.

Apex A parabola opens upward. The parabola goes through the point (3,-1), and the vertex (2,-2). What are the values of hand v? (2 point)

Answers

Since the parabola opens upward, the standard form of the equation for the parabola is:

y = a(x - h)^2 + k

where (h, k) is the vertex of the parabola.

We know that the vertex of the parabola is (2, -2), so we have:

y = a(x - 2)^2 - 2

We also know that the parabola goes through the point (3, -1), so we can substitute these coordinates into the equation and solve for a:

-1 = a(3 - 2)^2 - 2
-1 = a - 2
a = 1

Therefore, the equation of the parabola is:

y = (x - 2)^2 - 2

The values of h and v are the coordinates of the vertex, which we already know to be (2, -2). Therefore, h = 2 and v = -2

for t = 0, 1, 2, · · · . Suppose we have the following parameter
values:
n = 0.01
δ = 0.1
A0 = 5
k0 = 10
For all t ≥ 0, the exogenous technological progress follows the
following

Answers

Given the parameter values n, δ, A₀, and k₀, the endogenous technological progress A(t) can be calculated using a recursive formula. The value of physical capital k(t) can also be determined using a separate recursive formula. The specific values depend on additional parameters not provided.

To compute the value of the endogenous technological progress A(t) at time t, we can use the following recursive formula:

A(t+1) = (1 - δ) * A(t) + n * k(t)^θ

where:

- A(t) represents the value of technological progress at time t.

- δ is the depreciation rate, which is 0.1 in this case.

- n is the exogenous growth rate of technological progress, which is 0.01 in this case.

- k(t) is the value of physical capital at time t.

- θ is the elasticity of output with respect to capital, which is not provided in the given information.

To compute k(t), we can use the following formula:

k(t+1) = (1 - δ) * k(t) + i(t)

where:

- k(t) represents the value of physical capital at time t.

- δ is the depreciation rate, which is 0.1 in this case.

- i(t) is the investment at time t.

Since the investment i(t) is not given in the provided information, we cannot determine the exact values of A(t) and k(t) for each time period. However, we can use the given initial values to compute their values for the initial time period (t = 0).

Using the provided initial values:

A(0) = 5

k(0) = 10

We can substitute these values into the recursive formulas to compute A(1) and k(1):

A(1) = (1 - 0.1) * 5 + 0.01 * 10^θ

k(1) = (1 - 0.1) * 10 + i(0)

The values of A(1) and k(1) can then be used to compute A(2) and k(2), and so on, by iteratively applying the recursive formulas. The specific values of A(t) and k(t) for each time period would depend on the values of θ and the investment i(t), which are not provided.

What is the range?

The range is the set of values that come out to an outcome for a certain mathematical operation.

Here,

First find the function g(x),
So,
g(x) = -2(10ˣ) + 1


To calculate the range of the function g(x) = -2(10ˣ) + 1, we need to determine the set of all possible output values that the function can produce.

Notice that the function f(x) is a linear function of the form y = mx + b, where m = -2 and b = 1. Since the exponent function, 10ˣ is always positive, the value of -2(10ˣ) is always negative, and adding 1 to a negative number results in a range of all real numbers less than or equal to 1.

Therefore, the range of the function is range = {y | y ≤ 1} or in interval notation, this can be written as range = (-∞, 1]
