Answer:

Hexagonal Prism

Answer:

96feet

Step-by-step explanation:

Given the height, in inches, of a spray of water is given by the equation ℎ(x)=160−16x^2

x is the number of feet away from the sprinkler head the spray

To get the height of the spray 2 feet away from the sprinkler head, we will simply substitute x =2 into the function and et the height h as shown;

From the equation

ℎ(x)=160−16x^2

h(2) = 160-16(2)²

h(2) = 160-16(4)

h(2) = 160-64

h(2) = 96feet

Hence the height will be 96feet if the spray is 2feet away from the sprinklers head

-3x+2c = -3

-3 = -3x + 2c

3x = 2c + 3

x = (2c + 3)/3

The solution of the linear equation -3x+2c=-3 for the value of x will be x = (2c + 3)/3.

The equations have the degree of the variables equal to one. In other words, the highest power of the variables will be one. It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

The given linear equation -3x+2c=-3 will be solved as below:-

-3x+2c = -3

Take the two variables to the same side of the equation.

-3 = -3x + 2c

Separate the variable x from the other terms to get the value of x.

3x = 2c + 3

Divide both the sides of the equation by 3 and calculate for the value of x.

x = (2c + 3)/3

Therefore, the solution of the linear equation -3x+2c=-3 for the value of x will be x = (2c + 3)/3.

The 98% confidence interval for the true mean noise level is approximately (55.9, 57.1).

To find the 98% confidence interval for the true mean noise level, we can use the formula:

CI = mean ± Z * (σ / sqrt(n))

Where:

CI is the confidence interval,

mean is the sample mean,

Z is the z-score corresponding to the desired confidence level,

σ is the population standard deviation,

n is the sample size.

In this case, we have:

mean = 56.5 (sample mean)

σ = 3.5 (population standard deviation)

n = 180 (sample size)

Confidence level = 98%

First, we need to find the z-score corresponding to a 98% confidence level. The remaining 2% is split equally between the two tails of the distribution, so we have 1% in each tail. We can find the z-score using a standard normal distribution table or a graphing calculator. For a 98% confidence level, the z-score is approximately 2.33.

Now we can calculate the confidence interval:

CI = 56.5 ± 2.33 * (3.5 / sqrt(180))

CI = 56.5 ± 2.33 * (3.5 / 13.416)

CI = 56.5 ± 2.33 * 0.261

CI = 56.5 ± 0.607

CI ≈ (55.9, 57.1)

Therefore, the 98% confidence interval for the true mean noise level is approximately (55.9, 57.1).

The system of inequalities did not have any solution, but after reversing the  sign we will get a solution of the system of inequalities.

The inequalities are : y > 2x + 2/3 and y < 2x + 1/3

There is no intersection and no solution to the system since the region above the line y = 2x + 2/3 and the region below the line y = 2x + 1/3, respectively, are the solutions to the inequality y > 2x + 2/3 and y <2x + 1/3, respectively.

Now when the signs are changed we get:

y < 2x + 2/3 and y > 2x + 1/3

The region below the line y = 2x + 2/3 is the solution of the inequality

y= 2x + 2/3, and the region above the line y = 2x + 1/3 is the solution of the inequality y > 2x + 1/3. This implies that the area between the two lines is where the system's solution lies.

Cohen's conventions for interpreting d, this effect is small. Therefore, the correct answer is a. small.

According to Cohen's conventions for interpreting the effect size (d), the effect described in the study is considered "small." Cohen's conventions provide a general guideline for categorizing the magnitude of an effect size.

In this case, the effect size (d) is calculated to be 0.02. Cohen's conventions typically classify effect sizes as follows:

Small effect: d = 0.2

Medium effect: d = 0.5

Large effect: d = 0.8

Since the effect size of 0.02 is significantly smaller than the threshold for a small effect (0.2), it falls into the "small" category. This means that the difference in the number of words uttered per day between men and women, as reported in the study, is relatively small or negligible in practical terms.

To find the median time between breakdowns, we need to use the fact that the distribution of breakdown times follows an exponential distribution. The exponential distribution has a probability density function of f(x) = λe^(-λx), where λ is the rate parameter and x is the time between breakdowns.

The median time between breakdowns is the time t such that the probability of the time between breakdowns being less than t is 0.5. Mathematically, this can be expressed as P(X < t) = 0.5.

In the case of the Vexing Manufacturing Company, we are given that the average time between breakdowns is 30 minutes. The rate parameter λ of the exponential distribution is the inverse of the average time, which is λ = 1/30.

Using the cumulative distribution function (CDF) of the exponential distribution, we can find the median time t by solving the equation:

P(X < t) = 0.5

1 - e^(-λt) = 0.5

e^(-λt) = 0.5

-λt = ln(0.5)

t = -ln(0.5)/λ

t = 30 ln(2) ≈ 20.8 minutes

Therefore, the median time between breakdowns at the Vexing Manufacturing Company is approximately 20.8 minutes.

Here are the general steps for using the u-substitution method to evaluate a definite integral:

1. Identify a part of the integrand that looks like the derivative of another function.

This is usually denoted as u, and u should be a function that is easy to integrate.

2. Replace the selected part of the integrand with u. In other words, substitute u for the expression inside the integral.

3. Take the derivative of u with respect to the variable of integration, and then multiply by dx to obtain du.

4. Replace dx with the expression in terms of du, using the relationship you found in step 3.

5. Rewrite the entire integral in terms of u and du, and simplify as much as possible.

6. Evaluate the integral using u and the limits of integration. Replace u with the original expression, and then evaluate the expression at the upper and lower limits of integration.

7. Substitute the values obtained in step 6 into the original equation to get the final answer.

The u-substitution method is a powerful technique for evaluating definite integrals.

The general idea behind the u-substitution method is to replace a complicated expression inside the integral with a simpler expression, which is equal to the original expression.

Here are the general steps for using the u-substitution method to evaluate a definite integral:

Let's take an example to illustrate these steps:

Evaluate the definite integral ∫\((2x + 1)^(3/2) dx from x = 1 to x = 2.\)

Let u = 2x + 1.

Replace 2x + 1 with u in the integral to get ∫\(u^{3/2} dx.\)

Take the derivative of u with respect to x to get du/dx = 2, and then multiply by dx to obtain du = 2dx.

Replace dx with 1/2 du.

Rewrite the entire integral in terms of u and du to get ∫\(u^{3/2} (1/2) du.\)

Evaluate the integral using u and the limits of integration to get (2/5) \(u^{5/2}\) from 3 to 5.

Substitute the values obtained in step 6 into the original equation to get the final answer, which is\((2/5) [(5^{5/2}- 3^{5/2}].\)

Therefore, the value of the definite integral ∫\((2x + 1)^{3/2}\)dx from x = 1 to x = 2 is approximately 6.243.

Step-by-step explanation:

Similar question to the previous one you asked, and I swear I will not make the same mistake again :)

First we will find the displacement at t = 0 and t = 1 to find both displacements.

t = 0,

\(x(0)=4cos(\pi (0)+\frac{\pi }{4} )=4cos(\frac{\pi }{4} )\\=4(\frac{\sqrt{2} }{2} )\\=2\sqrt{2} m\)

t = 1,

\(x(1)=4cos(\pi (1)+\frac{\pi }{4} )=4cos(\pi +\frac{\pi }{4} )\\=4(-\frac{1}{\sqrt{2} } )\\=-\frac{4}{\sqrt{2} }\)

Total Displacement = Final Position - Initial Position

The probability that a basketball player with an accuracy rate of 70% will miss the first free throw, but make the second one, can be calculated using the geometric distribution formula.So, in this case, the probability is 0.7 x 0.3^1 = 0.21, or 21%.

This means that the probability of missing the first free throw, but making the second one, is 21%. This probability is lower than the probability of making the first free throw, which is 70%. This lower probability reflects the fact that a player is likely to make the first free throw due to their higher accuracy rate, and then make the second free throw with a lower accuracy rate.

In conclusion, the probability that a basketball player with an accuracy rate of 70% will miss the first free throw, but make the second one, is 21%. This probability is lower than the probability of making the first free throw due to the player’s higher accuracy rate.
