Find the value of x.
A) 10
B) 5√2 (5 radical 2)
C) 5√3 (5 radical 3)
D) 5

Answer:

(D) 72

Step-by-step explanation:

A factor is an integer that divides into a whole number without a remainder.

In this case, both 4 and 9 need to be the result of a division of 72 by some number. 4 is a factor of 8, since 8 divided by 2 is 4, but 9 isn't. 9 is a factor of 18, but 4 isn't. Neither 4 nor 9 is a factor of 49. If you divide 72 by 18, you get 4. If you divide 72 by 8, you get 9.

4 and 9 are factors of 72.

Answer:

y = -4x

Step-by-step explanation:

First, for an equation of form y=mx+b, m represents the slope. Therefore, for y=x/4+2 = (1/4)*x + 2, 1/4 is the slope. For perpendicular lines, the negative reciprocal of the slope is the slope of the line perpendicular to it. Therefore, the slope of our line is the negative reciprocal of 1/4.

To find the reciprocal of something, we can just divide 1 by it (another way to do this would be to flip the numerator and denominator, so 1/4 turns into 4/1). Therefore, 1/(1/4) = (1/1)/(1/4) = (1/1) * (4/1) = 4. The negative reciprocal is thus -4.

Our equation is therefore of form y = (-4) x + b. To solve for b, we can plug in the point given and solve for b in our equation. We have

-4 = (-4) * 1 + b

-4 = -4 + b

add 4 to both sides to isolate the b

0 = b

Therefore, our equation is

y= (-4)x + 0

y = -4x

the area of the surface that corresponds to the part of the plane 13x + 5y + z = 65 lying in the first octant is 32.5 square units.

To find the area of the surface that corresponds to the part of the plane 13x + 5y + z = 65 lying in the first octant, we need to find the equation of the portion of the plane that lies in the first octant and then calculate the surface area of that portion.

First, we need to find the intercepts of the plane with the x, y, and z-axes. Setting x = 0, we get:

5y + z = 65

Setting y = 0, we get:

13x + z = 65

Setting z = 0, we get:

13x + 5y = 65

Solving these three equations simultaneously, we get:

x = 5, y = 13, z = 0

So the plane intersects the x-axis at (5,0,0), the y-axis at (0,13,0), and the z-axis at (0,0,65).

The part of the plane that lies in the first octant is bounded by the x-axis, the y-axis, and the line connecting (5,0,0) and (0,13,0). This triangular region has a base of length 5 and a height of 13, so its area is (1/2)513 = 32.5.

Based on the given options, the relation that is symmetric is option A: {(a,b)|a=b}.

A relation is symmetric if for every (a, b) in the relation, (b, a) is also in the relation. In this case, for the relation to be symmetric, every element (a, b) in the relation must have its corresponding element (b, a) in the relation.

In option A, {(a,b)|a=b}, every element (a, b) in the relation is such that a is equal to b. For example, (1, 1), (2, 2), and (3, 3) are all part of the relation. Since the relation includes the corresponding elements (b, a) as well, it is symmetric.

Answer:

y=3/2x-2

Step-by-step explanation:

Since it is parallel it will have the same slope. Put the equation into y=mx+b form in order to easily identify the slope. 3x-2y=14. Subtract the 3x and divide by -2......From there you can see that the equation is y=-7 +3/2x. We cannot keep the -7 since it is parallel and wont have the same y intercept. Plug in the -11 for the y and the -6 for the x and solve for b (the new y int.) It should look like -11= 3/2(-6) +b....From there b should be -2. Final step is to rewrite the equation to be y=3/2x-2!

The required, rate of change of function B is greater than the rate of change of Function A.

Rate of change is defined as the change in value with rest to another entity is called rate of change.

Here,
For function 1 rate of change is given by the slope of the function,

m = (y₂ - y₁) / (x₂ - x₁)
m = 2 - 1 / 4 - 0
m = 1/4

m = 0.25

For function B, y = 0.75x - 2 rate of change has defined the slope of the function from the equation slope is m = 0.75.

So Slope of function B > Slope of function A

Thus, the rate of change of function B is greater than the rate of change of Function A.

The given error function E(z), with its z-transform E(z) = 3z³ / (z³ - 9z² + 27z - 27), can be expressed as the product of two z-transform equations E₁(z) and E₂(z), where E₁(z) and E₂(z) are fractional polynomials of z with first-order numerators.

To express E(z) as the product of two z-transform equations E₁(z) and E₂(z), we factorize the denominator of E(z):

E(z) = 3z³ / (z³ - 9z² + 27z - 27)

The denominator can be factored as follows:

z³ - 9z² + 27z - 27 = (z - 3)(z - 3)(z - 3)

Now, we define E₁(z) = 3z / (z - 3) and E₂(z) = z - 3. Multiplying them together, we obtain:

E₁(z) x E₂(z) = (3z / (z - 3)) x (z - 3) = 3z³ / [(z - 3)(z - 3)(z - 3)]

This expression is equal to E(z), as shown by the factored denominator. Therefore, we have proven that E(z) can be written as the product of two z-transform equations E₁(z) and E₂(z), where E₁(z) has a first-order numerator 3z and E₂(z) has a first-order numerator z - 3.

Answer:

Yes, people that taking part in an experiment are called variables.

There is normally one person called the dependent variable, and the other who is the independent variable.

The statement provided "people taking part in an experiment are called variables" is incorrect.

In an experiment, the individuals or subjects who participate and are observed or manipulated are not referred to as variables. Instead, they are called participants, subjects, or sometimes, respondents, depending on the context of the study.

Variables, on the other hand, are characteristics or properties that can vary or change among the individuals or subjects in the study. Variables can be classified as independent variables, dependent variables, or control variables.

Independent variables are manipulated or controlled by the researcher, while dependent variables are the outcomes or responses that are measured or observed.

Control variables are other factors that are held constant. Therefore, it is important to differentiate between the individuals participating in the experiment and the variables being studied.

The percentage of these funds are expected to be within ±6 standard deviations of the mean is 97.22% (approx).Hence, the required answer is 97.22.

The Chebyshev’s theorem is used to determine the percentage of observations that lie within a certain number of standard deviations of the mean in a set of data.

According to the Chebyshev rule, what percentage of these funds are expected to be within ±6 standard deviations of the mean can be calculated using the formula:

\($$1 - \frac{1}{k^2}$$\)

Where k is the number of standard deviations. For the question, the mean is 7.10 and standard deviation is 3.50.As per the given data, we can find that, the number of standard deviation from the mean is ±6.

Thus, k = 6.

The percentage of these funds are expected to be within ±6 standard deviations of the mean is:

\($$1 - \frac{1}{k^2} = 1 - \frac{1}{6^2} = 1 - \frac{1}{36} = 0.9722$$\)

The validity of short forms may be reduced because they contain fewer items compared to the full-length version. Short forms of tests or questionnaires are often used in research and clinical settings due to their convenience and efficiency.

This means that the short form may not fully capture the construct being measured and may not accurately reflect the individual's true scores. Additionally, the items selected for the short form may not be representative of the full range of the construct, leading to bias and limited generalizability.

Step-by-step explanation:

If you have a lot of problems with decimal coefficients (I know I do), you can get rid of them first.  Just multiply both sides of the equation by 10:

.3x² + 1 = .1

3x² + 10x = x

Answer:

1) False

2) True

3) True

4) False

Step-by-step explanation:

For the first statement, we can look at a graph with the line of y = 3.69x plotted. If we check the points (7.38, 2) and (11.07,3), they do not intersect with the line. So, the first statement is false.

For the second statement, we can check the equation for the line to find the slope. The equation, y = 3.69x, is in slope-intercept form, or \(y = mx + b\). In this form, \(m\) is the slope of the line. \(b\) is the y-intercept. In this line, there is no y-intercept specified, so we can take this to mean the y-intercept is 0. The slope, we can see, is 3.69. The slope, multiplied by x, shows us any point of the line. The second statement, then, is true.

The next statement can be verified by finding just how much 16 gallons will cost. Like we've seen before, the slope can be multiplied by x, the number of gallons, to see where that point will be plotted. So, we can multiply the slope by 16.

3.69 · 16 = 59.04

The (x) value, we already know, is 16. The (y) value, we've found, is 59.04. So 16 gallons will be plotted at  (16, 59.04). The third statement is true.

The last statement says that if the price increases by $0.05, the slope will be 3.64. We can tell this is false by adding 0.05 to the original slope, 3.69.

3.69 + 0.05 = 3.74

3.74 ≠ 3.64, so the last statement is false.
