Answer:

1. Growth

2. Decay

3. Decay

Step-by-step explanation:

Growth means as x increases, y increases too. On the other hand, decay means as x increases, y decreases. There's the theory for exponential function regarding this growth and decay.

Growth

If the base is not a decimal or a fraction then it's growth.

Decay

If the base is a decimal or a fraction then it's decay.

From the problem, first function has base of 5. Hence, it's growth. On the other hand, second and third function both have decimal and fraction as the base. Hence, it's decay.

When considering growth or decay graph, we can ignore the coefficient since it doesn't determine the growth and decay. The only thing that determines if a function increases or decreases is the base under the exponent.

It is true that in calculating which means differ, each pair of means needs a unique range.

To determine if two means are different, a statistical test such as a t-test or an ANOVA is typically used. These tests compare the means of two or more groups and require a unique range for each group. This range is typically represented by the variance or standard deviation of the group's data.

For example, if we have two groups of data, group A and group B, and we want to determine if the mean of group A is different from the mean of group B, we would need the range of data for group A and the range of data for group B. The range of data includes the variance or standard deviation which is used to calculate the t-value or the F-value which is used to determine if the means are significantly different. Without this information, we cannot accurately compare the means and determine if they are different.

The iterated integral is obtained by repeatedly integrating multivariate functions with a single variable each time. The given iterated integral is [tex]\int\limits^{\pi}_b\int\limits^1_0\int\limits^{\sqrt{1-z^2}}_0 z\sin(x)\;dy\;dz \;dx[/tex]. This integral is evaluated in the following order [tex]\int dy[/tex], [tex]\int dz[/tex], and [tex]\int dx[/tex].

Option D is the correct answer. The probability that a test correctly rejects a false null hypothesis is called the significance level.

The significance level, also known as alpha or α, is a measure of the strength of the evidence that must be present in your sample before you will reject the null hypothesis and conclude that the effect is statistically significant.

The probability of making a type II error (failing to reject the null hypothesis when it is actually false) is called β (beta). The quantity (1 - β) is called power, the significance level is the probability of rejecting the null hypothesis when it is true.

For example, a significance level of 0.05 indicates a 5% risk of concluding that a difference exists when there is no actual difference. Lower significance levels indicate that you require stronger evidence before you will reject the null hypothesis.

The quadratic equation is y = -25.42x² + 106.66x + 2.06 which fits the given points.

What is Quadratic regression?

Quadratic regression is a method of finding the equation of a parabola that best fits a set of data points. The equation for a parabola is y = ax² + bx + c, where a, b, and c are constants.

A quadratic equation that fits the given points can be found using quadratic regression.

To find the equation that fits the given points (0, 6.1), (1, 71.2), (2, 125.9), and (3, 89.4), we can use the method of least squares.

The method of least squares is a method of finding the equation that minimizes the sum of the squares of the differences between the actual y-values and the predicted y-values.

Using this method, we can find that the equation of the parabola that best fits the given points is y = -25.42x² + 106.66x + 2.06

This equation is in the form of y = ax² + bx + c, where a = -25.42, b = 106.66, and c = 2.06.

This equation can be used to predict the y-value for any x-value within the domain of the given points.

Hence, the quadratic equation is y = -25.42x² + 106.66x + 2.06 which fits the given points.

On solving the provided question related to rectangle we can say that the Perimeter, P = 2(10+20); P = 60 cm

The formula for the perimeter of a rectangle is, P = length + breadth + length + breadth The perimeter of a shape is always calculated by adding up the length of each of the sides. To find the perimeter of a rectangle, we add the lengths of all four sides. Since opposite sides of a rectangle are always equal, we need to find the dimensions of length and width to find the perimeter of a rectangle. We can write the perimeter of the rectangle as twice the sum of its length and width.

In order to find the perimeter, or distance around the rectangle, we need to add up all four side lengths.

This can be done efficiently by simply adding the length and the width, and then multiplying this sum by two since there are two of each side length. Perimeter=(length+width)×2 is the formula for perimeter

Step-by-step explanation:

After rewriting the given equation, we have the resultant equations as (B) -2.3p - 10.1 = 6.49p - 4 and (C) -230p - 1010 = 650p - 400 - p.

Two expressions joined by an equal sign form a mathematical statement known as an equation.

An equation is, for instance, 3x - 5 = 16. We can solve this equation and determine that the value of the variable x is 7.

So, we have the equation:
2.3p - 10.1 = 6.5p - 4 - 0.01p

Now, we can rewrite them as follows:

-2.3p - 10.1 = 6.49p - 4

-230p - 1010 = 650p - 400 - p

Therefore, after rewriting the given equation, we have the resultant equations as (B) -2.3p - 10.1 = 6.49p - 4 and (C) -230p - 1010 = 650p - 400 - p.

Occasionally, the acronyms "pct.," "pct," and "pc" are also used. But it is commonly indicated by the percent sign, "%." The % amount has no dimensions. Percentages are essentially fractions when the denominator is 100. Use the percent sign (%) to indicate that a number is a percentage by placing it next to it. For instance, you score a 75% if you properly answer 75 out of 100 questions on a test (75/100). Divide the money by the total and multiply the result by 100 to calculate percentages. The formula for calculating the percentage is (value/total) x 100%.

Answer:

To find the mean (average) of a set of numbers, we add them together and divide by the number of items in the set.

The first step is to convert all the fractions into a common denominator. In this case, the least common multiple of 3, 3, and 4 is 12.

2 1/3 = 7/3

3 2/3 = 11/3

5 1/4 = 21/4

Now we can add these numbers together:

7/3 + 11/3 + 21/4 = (7 + 11 + 21) / 3 = 39/3 = 13

There are three numbers, so we divide by 3.

Mean = 13/3 = 4 1/3

So the mean of 2 1/3, 3 2/3 and 5 1/4 is 4 1/3.

Step-by-step explanation:

The linear equation L, which is a translation of line M, can be written as:

y = (2/3)*x - 2

So the correct option is the last one.

First, we need to find the equation of line M.

Remember that the general linear equation is:

y = a*x + b

Where a is the slope and b is the y-intercept.

On the graph we can see that the y-intercept is y = -2, then we wll get:

y = a*x - 2

And we can also see that the line passes through (-3, -4)

Replacing these values we will get:

-4 = a*-3 - 2

-4 + 2 = -3a

-2/-3 = a

2/3 = a

So line M is:

y = (2/3)*x - 2

And line M is a translation of 3 units down and 2 units left of L, then L is a translation of 3 units up and 2 units to the right, then we can write line L as:

y = (2/3)*(x - 2) - 2 + 3

y = (2/3)*x + (2/3)*-2 - 2 + 3

y = (2/3)*x - 4/3 + 1

y = (2/3)*x - 1/3
