if the diameter of a sphere is 160 what is the volume

Answer:

x = -3.57

Step-by-step explanation:

First, subtract the answer and the other interger: -5.37 - (-1.8). Two negatives equal a negative. So, your answer would be -3.57

To double check, you would add -3.57 + (-1.8) [-+-=-] Equals, -5.37.

True, to calculate the average of numeric values in the list, the first step is to get the total of values in the list.

Steps to calculate the Average:

Let’s assume there are 4 numbers having values of 2,8,22,48 respectively.

To find the average we first have to take the total of all values.

2+8+22+48=80.

Our next step will be to divide this total by the number we have in our question i.e., 4.

so, our average will be 80/4= 20.

So, 20 will be our average.

So yes, it is true that to calculate the average of numeric values in the list, the first step is to get the total of all values in the list.

The best description of the relationship between the y-axis and the line connecting F to F' after reflection over the y-axis is that they are perpendicular to each other.

When a triangle is reflected over the y-axis, its vertices swap their x-coordinates while keeping their y-coordinates the same. Let's consider the points F and F' on the reflected triangle.

The line connecting F to F' is the vertical line on the y-axis because the reflection over the y-axis does not change the y-coordinate. The y-axis itself is also a vertical line.

Since both the line connecting F to F' and the y-axis are vertical lines, they are perpendicular to each other. This is because perpendicular lines have slopes that are negative reciprocals of each other, and vertical lines have undefined slopes.

Therefore, the best description of the relationship between the y-axis and the line connecting F to F' after reflection over the y-axis is that they are perpendicular to each other.

-10 is closer to zero therefore -10 is the answer

Answer:

-10 is greater than -31

Step-by-step explanation:

To compare numbers, place them on the number line. A number is greater than a number to its left.

Example of the range of a function is given as follow:

f(x) = 2x + 1 , x∈N, x < 5 then its range is equal to { 3, 5, 7, 9}.

As given in the question,

Range of any given function is defined as collection of all the output values of the given function.

Let us consider an example to represent the range of the given function:

f(x) = 2x + 1 where x ∈ N , x < 5

Here x belongs to natural numbers less than 5 which implies x is equal to 1, 2, 3, 4.

Substitute the values of x to get the range (output values ).

f(1) = 2(1) + 1

    = 3

f(2) = 2(2) + 1

     = 5

f(3) = 2(3) + 1

     = 7

f(4) = 2(4) + 1

     = 9

Range of f(x) = { 3, 5, 7, 9 }.

Therefore, the range of any function is its output values example

f(x) = 2x + 1 , x ∈ N , x < 5 have range = { 3,5,7,9}.

Step-by-step explanation:

area of rectangle =l×b

A statistical analysis is internally valid if option B is correct, meaning that the statistical inferences about causal effects are valid for the population studied. Internal validity refers to the accuracy of conclusions drawn from a study, specifically focusing on causal relationships within the population being analyzed.

Statistical analysis is a method of examining data to identify patterns and trends, which can help researchers make informed decisions. Regression is a technique used to determine the relationship between two or more variables, where one variable (the dependent variable) is affected by one or more other variables (independent variables).

The population refers to the entire group of individuals or objects being studied. In order to have internal validity, the statistical analysis must accurately represent the population's characteristics and the causal relationships between variables.

R² (option A) is a measure of how well the regression model fits the data but doesn't necessarily imply internal validity. Option C, t-statistics, is related to hypothesis testing and helps determine if a relationship between variables is statistically significant. However, having all t-statistics greater than |1.96| doesn't guarantee internal validity.

Lastly, option D states that the population is small (less than 2,000) and can be observed. While having a smaller population might make it easier to gather data, this does not guarantee internal validity.

In summary, internal validity is achieved when the statistical inferences about causal effects are valid for the population studied (option B). It ensures that the conclusions drawn from a study are accurate and represent the true relationships within the population.

Answer:

x= -4

Step-by-step explanation:

Subtract 7 from both sides

-5x + 7 - 7 = 27 - 7

-5x =  20

Divide both side by -5

-5x/-5 = 20/-5

x = - 4

Jutin chooses a function J(x) = 3x - 1 that when he uses the number 7 as an input, then the output is 20.

As per the given data, Jutin chooses a function in which he uses the number 7 as an input, then the output is 20.

Here we have to determine which function Jutin has to use.

Now we have to substitute the value that x = 7 in all the given functions.

First function:

F(x) = 2\(x^{5}\)

F(7) = 2 \((7)^{5}\)

F(7) = 2 (16807)

F(7) = 33614 which is not equal to 20.

Second function:

G(x) = \(x^{2}\) - 19

F(7) = \((7)^{2}\) - 19

F(7) = 49 - 19

F(7) = 30 which is not equal to 20.

Third function:

H(x) = 13 - x

H(7) = 13 - 7

H(7) = 6 which is not equal to 20.

Fourth function:

J(x) = 3x - 1

J(7) = 3(7) - 1

J(7) = 21 - 1

J(7) = 20

The correct function is J(x) = 3x - 1

x = 2

x = -1/3

Step-by-step explanation:

Hi there!

You'll notice that this equation is a quadratic. When graphed, this equation looks like a parabola that crosses the x-axis at two points, which can be written as ordered pairs with an x value and a y value.

We know that both of these points will have a y value of 0, but we don't know what the x values of the points are—these are what we want to find.

(Check out the graphing program Desmos—type in your equation and it will graph it out for you.)

Notice that your equation follows this structure:

\(ax^2+bx+c=0\)

In our case,

\(a=3\\b=-5\\c=-2\)

We can plug our values of a, b, and c into the quadratic equation to find the two x values.

I've attached a picture of my work. At the top is the quadratic equation. I substituted our values in and solved.

You'll notice that the answer I ended up with has a ± symbol. We have to simplify this down two different ways to get our two answers: once using the plus sign, once using the minus sign. This will give us two different values for x.

We'll start with the plus sign:

\(\frac{5+7}{6} \\=2\)

So: one of our x values is 2.

Now the minus:

\(\frac{5-7}{6} \\=-\frac{1}{3}\)

Our other x value is -1/3.

You can check to make sure these answers work by plugging them back into the original equation for x. If they work, the left side of the equation should boil down to 0.

Step-by-step explanation:

All angles of a triangle add up to 180 degrees.

Two angle measures are provided, 100 and 35 (?)

Add up the two to get 135, and subtract from 180

180 - 135 = 45 degrees.

I might be seeing the rightmost angle measure wrong but I think it's 35, if it's not you can still apply the same strategy, just add the two given angles and subtract that from 180 to find x.

Answer:

True

Step-by-step explanation:

The statement is true. If a finite number of terms are added to a convergent series, then the new series is still convergent.

A convergent series is a series whose sum approaches a finite limit as the number of terms increases. When you add a finite number of terms to a convergent series, the sum of the series is simply increased by the sum of those additional terms. Since the original series converges to a finite limit, adding a finite sum to that limit will result in another finite limit, meaning that the new series will also be convergent.

In summary, adding a finite number of terms to a convergent series does not change its convergence properties and will result in a new convergent series with an updated finite limit.
