A dog eats soft food out of a 16oz packet. Every day the dog eats its meals split into three dishes breakfast, lunch, and dinner. If the dog needs to eat 11oz daily, how many oz would be in each dish?

Answers

A dog eats soft food out of a 16oz packet. Every day the dog eats its meals split into three dishes breakfast, lunch, and dinner. If the dog needs to eat 11oz daily, each dish would have 3.67oz of food.

To find out  oz would be in each dish, we need to divide the total amount of food the dog needs to eat daily (11oz) by the number of dishes (3). This will give us the amount of food in each dish.

Here's the math:

11oz ÷ 3 dishes = 3.67oz per dish

Choose the sample size and significance level that will lead to a test having the highest power. N=20 n=60 n=120 a=0. 01 a=0. 05 a=0. 10

Answers

The sample size of N=120 and significance level of α=0.01 would be the most likely to lead to the highest power.

To maximize statistical power, we want to select the sample size and importance degree in order to maximize the likelihood of detecting a real effect if one exists. Better pattern size and a decreased importance degree each tend to increase statistical energy.

Assuming a -tailed test and equal variances, we will use a power analysis to determine the sample size needed to acquire a favored degree of power. Based totally on the impact size we count on to examine, we will estimate the minimum sample size required for the take look to have 80% energy (that is regularly considered acceptable).

For instance, if we count on a small impact length (d=0. 2) and an importance level of α=0. 05, we might need a pattern size of about n=128 to reap 80% power. Growing the sample length in addition would retain increased strength, however, the marginal returns could diminish.

As for significance level, lower alpha degrees tend to cause higher strength due to the fact they lessen the possibility of a type I error (false wonderful), which frees up extra of the kind I error rate for detecting genuine outcomes. However, excessively low alpha tiers can boom the chance of kind ii errors (fake negatives), which decreases strength.

Answers

Answer:4. (a) BMN = 75°(b) AMP = 105°Explanation:Given that ABC is an isosceles triangle with base BC, and ABC = 75°. Also, BC = MB = PM and MN || BC.(a) To find BMN, we can use the fact that MN || BC. This means that ∠BMN = ∠ABC = 75°. Therefore, BMN = 75°.(b) To find AMP, we can use the fact that BC = MB = PM. This means that triangle BMP is an isosceles triangle with base MP. Since BMN = 75°, we can find ∠BMP by using the fact that the sum of the angles in a triangle is 180°:∠BMP = (180° - 75°)/2 = 52.5°Now, we can find AMP by using the fact that the sum of the angles in a triangle is 180°:AMP = 180° - 75° - 52.5° = 52.5°Therefore, AMP = 105°.

(a) The angle BMN is 30°.

(b) The angle AMP is 15°.

The total angle of a triangle is 180°.

How to find the angle in a triangle?

We have an isosceles triangle ABC with base BC and ∠ABC is 75°. We construct point M on AC and N, P on AB. It makes BC = MB = PM and MN || BC.

Since ABC is an isosceles triangle, ∠ACB is also 75°. See the picture attached!

Since BC = MB, the triangle MBC is isosceles with base MC. So, BMC is 75°.

The angles of triangle MBC will sum up to 180°. So,

∠MBC = 180 - (75 + 75) = 30°

The angle BMN and MBC is alternate interior angles, so

BMN = ∠MBC = 30°

Now, we have ∠NBM = 75 - 30 = 45°. Since MB = PM, it makes BMP an isosceles triangle. The angle BPM will be the same with PBM. It is 45°.

The angle PMN will be

= 180 - (45 + 45 + 30)

= 60°

The angle CMB, BMN, NMP, and AMP are supplementary. So, the angle AMP is

= 180 - (75 + 30 + 60)

= 15°

Elise has $15 to spend on a paddle boat ride she uses this inequality to determine x the number of hours she can afford to rent the paddle boat

1.25x + 6.50 ≤ 15

What is the solution to the inequality?

x ≥ 17.2
x ≥ 6.8
x ≤ 17.2
x ≤ 6.8

Answers

The solution to the inequality is x ≤ 6.8. This means that Elise can afford to rent the paddle boat for a maximum of 6.8 hours if she has $15 to spend.        

Why does inequality matter?

Experts claim that disparity fosters political unrest and impedes economic growth. Concentrated financial resources reduce demand for products and services because affluent families generally spend less of their revenue than do poorer households. If low-income people have fewer choices, the company might suffer.

To solve the inequality 1.25x + 6.50 ≤ 15, we can start by isolating x on one side of the inequality:

1.25x + 6.50 ≤ 15

Subtract 6.50 from both sides:

1.25x ≤ 8.50

Divide both sides by 1.25:

x ≤ 6.8

Therefore, the solution to the inequality is x ≤ 6.8. This means that Elise can afford to rent the paddle boat for a maximum of 6.8 hours if she has $15 to spend.

Work out the value of x?​

Answers

Using angle theorems the value of x = 67.5°

What are angle theorems?

Angle theorems are rules that govern the properties of angles.

Given that we have the figure and we desire to find angle x, we proceed as folllows.

Now, we notice that one angle is a right angle and it is equal to 90°.

Also, we notice that all the angles meet at the same point.

So, we have that

x + 3x + 90° = 360° (sum of angles at a point)

Solving for x, we have that

x + 3x + 90° = 360°

4x + 90° = 360°

4x = 360° - 90°

4x = 270°

x = 270°/4

x = 67.5°

So, the value of x = 67.5°

Question 19 If $50,000 is invested in an account earning 5% compounded continuously, determine how long it will take the money to Wruble Write vour answer as an exact value.

Answers

It will take approximately 13.86 years for the money to double when it is invested in an account earning 5% compounded continuously.

To find out how long it will take for the money to double, we can use the formula for continuous compounding: A = Pe^(rt), where A is the final amount, P is the principal amount, r is the interest rate, and t is the time in years.

We are given that P = $50,000, r = 5%, and A = 2P = $100,000. We need to solve for t.

Plugging in the given values, we get:

$100,000 = $50,000e^(0.05t)

Dividing both sides by $50,000, we get:

2 = e^(0.05t)

Taking the natural logarithm of both sides, we get:

ln(2) = 0.05t

Solving for t, we get:

t = ln(2)/0.05

t ≈ 13.86 years

Therefore, it will take approximately 13.86 years for the money to double when it is invested in an account earning 5% compounded continuously.

Write a EM wave and EM wave equation?

Answers

An EM wave is written line E = E0 sin(kx - ωt) and EM wave equation is written as ∂²E/∂x² = μ₀ε₀∂²E/∂t²

An electromagnetic wave (EM wave) is a type of wave composed of an electric field and a magnetic field that propagate at the speed of light. The equation for an EM wave is given by E = E0 sin(kx - ωt), where E0 is the peak electric field, k is the wavenumber, ω is the angular frequency, x is the position, and t is time.

An ELECTROMAGNETIC WAVE, or EM wave, is a type of wave that travels through space and carries energy from one point to another. EM waves are created when electric and magnetic fields interact with one another. These waves are categorized by their frequency, which determines their energy and their wavelength.

The EM wave equation, also known as the wave equation, is used to describe how EM waves propagate through space. The equation is typically written in the form:

∂²E/∂x² = μ₀ε₀∂²E/∂t²

Where E is the electric field, μ₀ is the permeability of free space, ε₀ is the permittivity of free space, x is the position, and t is the time. This equation shows how the electric field changes over time and space, and is used to predict the behavior of EM waves.

Volume = πr2h

= 15,444.4 cubic feet

15,444.4 cubic feet x 7.48 gallons/cubic feet = 115,511.17 gallons

115,511.17 gallons - 54,000 gallons = 61,511.17 gallons

61,511.17 gallons + 54,000 gallons = 115,511.17 gallons

115,511.17 gallons is the total capacity of the tank.

The tank is able to hold up to 90,000 gallons of water, since it already contains 54,000 gallons and 60% of that is food. This means that the tank can still hold up to 36,000 gallons of water, giving it a total capacity of 90,000 gallons. This is possible because the tank is in the shape of a cylinder, which means that the volume of the tank is determined by the formula V = πr2h, where V is the volume, r is the radius, and h is the height. This means that the tank can be adjusted accordingly to increase or decrease the amount of water it can hold. In this case, the tank is able to hold up to 90,000 gallons of water because the capacity of the tank is determined by the size of its radius and height, and can be adjusted accordingly to increase or decrease the amount of water it can hold.

If the selection is made randomly, there are 30045015 ways to select a committee of size 10 from a group of 10 men and 20 women. The probability that the committee consists of 5 men and 5 women is 0.129. The probability that there is no woman in the committee is  0.000000033.

1. The total number of ways to select a committee of size 10 from a group of 10 men and 20 women is given by the combination formula:
C(n,k) = n! / (k! * (n-k)!)
Where n is the total number of people (10 men + 20 women = 30) and k is the size of the committee (10).
C(30,10) = 30! / (10! * (30-10)!)
C(30,10) = 30! / (10! * 20!)
C(30,10) = 30045015
Therefore, there are 30045015 ways to select a committee of size 10 from a group of 10 men and 20 women.

2. The probability that the committee consists of 5 men and 5 women is given by:
P(5 men and 5 women) = C(10,5) * C(20,5) / C(30,10)

11x-10+80=180 solve for x

Answers

Answer:

To solve for x, we need to isolate it on one side of the equation by performing inverse operations.

11x - 10 + 80 = 180

First, we combine the constant terms on the left side of the equation:

11x + 70 = 180

Next, we isolate the variable term by subtracting 70 from both sides:

11x = 110

Finally, we solve for x by dividing both sides by 11:

x = 10

Therefore, the solution to the equation 11x - 10 + 80 = 180 is x = 10.

11X=180+10-80
11X=110
11x/11=110/11

(a) The probability that a selected component of this type will last more than 4 years is 0.69.

(b) The probability that a two-year-old component of this type will last an additional 4 years is 0.57.

(c) The 25th percentile of the lifetimes of such components is 3.38 years.
Explanation:

(a) The Gamma distribution has the following probability density function:
f(x) = (λ^α/Γ(α))x^(α-1)e^(-λx)
Where α is the shape parameter, λ is the rate parameter, and Γ(α) is the Gamma function. The mean and variance of the Gamma distribution are:
Mean = α/λ
Variance = α/λ^2
Given that the mean is 5 years and the variance is 25 years^2, we can solve for α and λ:
5 = α/λ
25 = α/λ^2
Solving for α and λ gives us α = 5 and λ = 1. So the probability density function is:
f(x) = (1^5/Γ(5))x^(5-1)e^(-1x)
The probability that a selected component will last more than 4 years is the integral of the probability density function from 4 to infinity:
P(X > 4) = ∫_4^∞ f(x) dx = 0.69

(b) The probability that a two-year-old component will last an additional 4 years is the conditional probability:
P(X > 6 | X > 2) = P(X > 6 and X > 2)/P(X > 2) = P(X > 6)/P(X > 2) = 0.57

(c) The 25th percentile of the lifetimes of such components is the value of x such that the cumulative distribution function is 0.25:
F(x) = 0.25
∫_0^x f(x) dx = 0.25
Solving for x gives us x = 3.38 years.

Answers

matrix is 0.3 x 4 = 1.10

To determine the determinant of this 3 x 3 matrix, you can use the Laplace Expansion method. First, cross out the third column and calculate the determinant of the 2 x 2 matrix that remains:



0.6 0.8

0.5 0



The determinant of this 2 x 2 matrix is 0.6 x 0 - 0.8 x 0.5 = 0.3.



Next, multiply this result by the last element of the third column, which is 4. So the determinant of the 3 x 3 matrix is 0.3 x 4 = 1.10.

If the scale factor of a dilation is 8: 7, what kind of image does it create?

Answers

The required correct option out of given is B) This scale factor results in an enlarged image is correct.

What is scale factor of a dilation?

Finding the dilation's center point is the first step in determining the scale factor. Next, we measure the distances between the center point and various points on the preimage and the image. According to Math Bits Notebook, the scale factor is equal to the ratio of these lengths.

According to question:

When the scale factor of a dilation is greater than 1, the image is an enlargement.

In this case, the scale factor is 8:7, which means that every length in the image is 8/7 times larger than the corresponding length in the original figure. Therefore, the image is larger than the original figure.

So; B) This scale factor results in an enlarged image is correct.

Write a number to complete each sentence. The polynomial 7x^(7)-9x^(5)+3x^(4)+12x+1 has roots.

Answers

The polynomial 7x^(7)-9x^(5)+3x^(4)+12x+1 has four roots. Roots are the values of x that make the polynomial equal to zero. To find these values, one can use a variety of methods, such as factoring, graphing, and the quadratic formula.

Factoring is the simplest method to use, and it involves breaking the polynomial down into simpler terms. In this case, the polynomial can be broken down into the product of two linear polynomials (7x^(7)-9x^(5) and 3x^(4)+12x+1). By setting each factor equal to zero and solving for x, you can find the roots.

Graphing is also a useful tool for finding the roots of a polynomial. By graphing the polynomial, you can see the x-intercepts, which are the values at which the graph crosses the x-axis. These are the roots.

Finally, the quadratic formula can be used to find the roots of this polynomial. This formula is a general solution for any quadratic equation, and it can be applied to the polynomial by replacing the coefficients of x^2 with those of x^7 and solving for x.

In conclusion, the polynomial 7x^(7)-9x^(5)+3x^(4)+12x+1 has four roots. These can be found using factoring, graphing, or the quadratic formula.
