1. Growth
2. Decay
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.

Find the mean of the three numbers at the right 2 1/3 3 2/3 5 1/4
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.

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.
What are equations?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.

Line m represents a translation of line L3 units down and 2 units left. Which equation represents line L?
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.
How to find the equation of line L?
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
So the correct option is the last one.

D. significance level
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.

FIND THE EQUATION OF THE LINE THAT IS PERPENDICULAR TO 2Y - 3X = 10 THROUGH POINTS (-8,-1).
First you turn the equation into y=mx+b form.
2y-3x=10
2y=3x+10
2y/2=(3x+10)/2
y=3/2x+5
Next you take the opposite of the slope.
Slope = 3/2
Opposite = 2/3
Then you insert your values into y-y1=m(x-x1)
y+1=2/3(x+8)
y+1=2/3x+16/3
The answer is

in calculating which means differ, each pair of means needs a unique range. t/f
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.

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.

How to Find the Perimeter of a Rectangle?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

we have length, L = 10
and breadth, B = 20
Perimeter, P = 2(10+20)
P = 60 cm

Which step is the most efficient way to find the solution of x + 4 > -8?
A. Add 4 to both sides.
B. Substitute 1 for x and see if it works.
C. Subtract 4 from both sides and switch the inequality symbol.
D. Subtract 4 from both sides.
Answer:The most efficient step to finding the solution to the given inequality is, to subtract 4 from both sides. Option D is correct.
Given that,
To determine which step is the most efficient way to find the solution of x + 4 > -8.
Step-by-step explanation:

Answer:
(d) 3 + x = 14
Step-by-step explanation:
You want to know an equation that can help you find the number who arrived late, if the total of an initial 3 and the number who arrived late is 14.
EquationYou want to express that an unknown number, added to three, makes a total of 14:
3 + x = 14
