Which absolute value equation represents the graph?

 The region that lies inside the cylinder between the planes z = −2 and

z = 5 is 324π

Using cylindrical coordinates,

the integral becomes

∫∫∫ (r2) drdθdz, E

where E is the region that lies inside the cylinder r2 = 9 and between the planes z = −2 and z = 5.

The integral can be evaluated as follows:

=  ∫₋₂⁵∫₀²π∫₀³ [tex]r^2[/tex]drdθdz

= ∫₋₂⁵∫₀²π(3[tex]r^3[/tex]/3) dθdz

=  ∫₋₂⁵ (2π × (3 × 93/3)) dz

=  ∫₋₂⁵ (108π) dz

= (108π × (5 − (−2)))

Answer:

a+k =7

Step-by-step explanation:

In the given system of equations, ax + 3y = 10 and kx - 3y = 6, we are told that the solution to the system is (2,1). This means that when we plug the values x = 2 and y = 1 into the equations, we get two true statements.

To find the value of a + k, we can start by plugging the values x = 2 and y = 1 into the first equation to get:

a(2) + 3(1) = 10

Next, we can solve for a by dividing both sides of the equation by 2:

a + 3/2 = 5

a = 5 - 3/2 = 5/2

Next, we can plug the values x = 2 and y = 1 into the second equation to get:

k(2) - 3(1) = 6

Next, we can solve for k by dividing both sides of the equation by 2:

k - 3/2 = 3

k = 3 + 3/2 = 9/2

Finally, we can add the values of a and k to find the value of a + k:

a + k = (5/2) + (9/2) = 14/2 = 7

Therefore, the value of a + k is 7.

The statement that is true about Denzel's experiment is that D. The outcomes do not appear to be equally likely, so a uniform probability model is not a good model to represent probabilities in Denzel's experiment.

Uniform models are only useful for equally likely probabilities, so they are ineffective here. In statistics, a uniform distribution is a type of probability distribution in which every possible outcome has an equal chance of occurring. Because each variable has an equal chance of being the outcome, the probability is constant.

All events have an equal chance of occurring in a uniform probability mode. Rolling any one side of a six-sided fair die, for example, has the same probability: one out of six. In this situation, when Denzel randomly selects a single card, writes down the number, and then places it back in the bag, the probability are different.

Therefore, the correct option is D.

The test statistic calculated for this scenario is the test of the significance of the mean.

Mean is a measurement of a probability distribution's central tendency along the median and mode. It also goes by the name "anticipated value."

For example, if there are 3 students getting numbers 10, 20, and 30 in math then their mean is 10 + 20 + 30 / 3 = 60 / 3 = 20.

Given:

What is a triangle?

A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.

Given that the height of the cheese is 2.5 inches and the base is 4.75 inches.

The value of 1 inch is 2.54 centimeters.

Now convert 2.5 inches and 4.75 inches into centimeter:

2.5 inches = (2.5 × 2.54) centimeters = 6.35 centimeters

4.75 inches = (4.75 × 2.54) centimeters = 12.065 centimeters

The area of triangle is (1/2) × base × height

The inequality expression y ≥ 0 means that

The value of y is atleast 0

The probability that the buyer waits more than 10 minutes means that

y = 10

So, we have the following representation

y = 10 in fy(y)=0.2e^(-0.2y)

Substitute the known values in the above equation, so, we have the following representation

Let's now list every perfect square from 1 to 10 in the following order: 1, 4, 9, 16, 25, 36, 49, 64, 81, and 100.

As a result, we can observe that 25 is equal to the product of 1 plus 49.

The possible outcomes are 1, 25, and 49.

If x = 49 and z = 1, then

x + z / 2 = y

49 + 1 / 2 = y

Step-by-step explanation: because its ascking to describe the formation.

This z-score tells you x = 34 is 2.75 standard deviations to the right of mean. And the mean is 23.

What is standard deviation?

The standard deviation is a statistic that expresses how much variation or dispersion there is in a set of values. While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the set mean.

Given:

Annie averages 23 points per basketball game with a standard deviation of 4 points.

Suppose Annie's points per basketball game are normally distributed.

Let X = the number of points per basketball game.

By Notation,

X ~ N(23,4) means E(X) = 23, SD(X) = 4

Mean = 23 , Standard deviation = 4

So,

[tex]Z_s_c_o_r_e = \frac{Value - Mean}{Sd}\\Z_s_c_o_r_e = \frac{34-23}{4}\\ = \frac{11}{4} Z_s_c_o_r_e = 2.75[/tex]

mean = 23

This z-score tells you x = 34 is 2.75 standard deviations to the right of mean.

Step-by-step explanation:

you marked the important pieces of information correctly.

a parallel line must have the same slope. otherwise it is tilted differently, and it is therefore not parallel.

the slope in a y = ... equation is always the factor of x.

in our case therefore 1/5.

so, the parallel line starts with

y = (1/5)x + b

and to get b we use the x and y coordinates of the given point :

3 = (1/5)×5 + b = 5/5 + b = 1 + b

b = 2

and our equation is

y = (1/5)x + 2

The value of the standard deviation does not change and remains the same.

Given, a retired statistic professor has recorded final exam results for decades. the mean final exam score for the population of a student is 82.4 with a standard deviation of 6.5.

The mean μ = 82.4

The standard deviation σ = √[ ((x - μ)2 + (y - μ)2 + (z - μ)2)/3 ]

we have to find the variance,

We now add a constant k to each data value and calculate the new mean μ'.

μ' = ((x + k) + (y + k) + (z + k)) / 3 = (x + y + z) / 3 + 3k/3 = μ + k

We now calculate the new mean standard deviation σ'.

σ' = √[ ((x + k - μ')2 +(y + k - μ')2+(z + k - μ')2)/3 ]

Note that x + k - μ' = x + k - μ - k = x - μ

also y + k - μ' = y + k - μ - k = y - μ and z + k - μ' = z + k - μ - k = z - μ

Therefore σ' = √[ ((x - μ)2 +(y - μ)2+(z - μ)2)/3 ] = σ

If we add the same constant k to all data values included in a data set, we obtain a new data set whose mean is the mean of the original data set PLUS k. The standard deviation does not change.

Hence, the standard deviation does not change.

Given,

Suppose that there are 5 children in a gymnastics class.

One day, they count the number of steps each person takes while walking on their hands until they lose balance and come down.

The mean number of steps these children took while walking on their hands is 20 steps.

Here we need to find the the population and parameter.

Based on the given question,

We know that the parameters are descriptive measures of an entire population and their values are usually unknown because it is infeasible to measure an entire population.

Therefore, you can take a random sample from the population to obtain parameter estimates.

Similarly, for the population could simply be referred to as the total number or set of similar objects or subjects related to a certain study or research.

Here the given scenario described above, the area of interest is a particular gymnastic class, therefore all individuals or children belonging to this particular gymnastic class makes up the population.

And then the parameter on the other hand are statistical metrics, values or calculations derived from the population figure or information.

So, the mean value of steps obtained from the step counts of the population data is called the parameter.

And the parameter is a value that describes a characteristic of an entire population, such as the population mean.

Therefore, the population mean and standard deviation are two common parameters.

A load charge is a sales commission that investors pay when they buy (front-end load) or redeem (back-end load) shares in a mutual fund.

NAV means net asset value.

NAV refers to the difference between the investee company's total assets and its total liabilities.

The total number of mutual fund shares bought by Bill = 800
