Find three consecutive numbers whose sum is 84
Answer:
27 28 29
Step-by-step explanation:
Let the first be n , and if they are consecutive then the next two numbers are n+1 and n+2.
n+(n+1)+(n+2)=84.
3n+3=84.
⇒3n=81.
⇒n=27.
Hence numbers are n,n+1,n+2→27,28 and 29

the age distribution of a population (relative proportions of people of different ages) is not important when considering the growth rate of that population.
It is False to state that the age distribution of a population is not important when considering the growth rate of that population.
What is the growth rate of a population?Population growth is the rise in the number of inhabitants in a population or scattered group and it is usually stated in percentage.
Researchers often focus on four primary elements when forecasting changes in population size:
Birth rates,Death rates (life expectancy),The beginning age profile of the population (i.e. elderly or relatively young individuals), and Migration.Other factors include:
Economic development Social and cultural factorsEducation, etcAge distribution and statistics allow the pace of population growth to rise or decline as it is linked to the level of economic development of a population. a fast-expanding country's population has a pyramid-shaped age structure, with a higher share of younger people of reproductive age.
Therefore, we can conclude that it is False to state that the age distribution of a population is not important when considering the growth rate of that population.

As captain of the cheer team Lily is choreographing a routine for a competition. The minimum allowable length for a routine is 3 minutes and the maximum allowable length for a routine is 5 minutes. Write an absolute value for which the two solutions are the minimum and maximum allowable lengths.
Lily, the cheer team's captain, is putting together a performance for a tournament. A routine may be no less than 3 minutes in length and no more than 5 minutes in total. For which the two solutions are the shortest and longest permitted lengths, write an absolute value.
The absolute value for 3 is 3 .
The absolute value for 5 is 5.
The two solutions are the shortest and longest permitted lengths, The absolute value |2x−5|+|2x−3|=2
Absolute value is the non-negative value of a real number x, independent of its sign, is its absolute value (or modulus), | x |.
For example, 5 has an absolute value of 5, and -5 has a value of 5. Another way to think about a number's absolute value is as its distance from zero on the real number line. In addition, the distance between two real numbers is the absolute value of their difference.
Given that,
A routine may be no less than 3 minutes in length and no more than 5 minutes in total.
By absolute value equation
we can get 2x−5|+|2x−3|=m
By solving we get 2 m values they are,
m={-8,2}
Here, -8 we can take but the answer will be in decimal soo we take 2.
|2x−5|+|2x−3|=2
We get

2) 2a + 4x when a is 2 and x is 8
Step-by-step explanation:
Which statement is true about the function f(x)=8^3
The function f(x) = 8 is even because f(x)= f(-x).
Given the function is f(x) = 8
Key to find if a function f(x) is even or odd is to replace the x with -x.
if the results comes out to be f(x) then it is even function.
if the results comes out to be -f(x) then it is odd function.
where as graphically even f(x) will be symmetric around the y-axis and odd f(x) will be symmetric around the origin.
In given case f(x)= 8
if we replace x with -x in above equation then results is 7
f(-x)= 8
hence f(x)= f(-x) = 8
Therefore, f(x) = 8, is an even function.

let a be the event that the sum of the faces showing is 6 and let b be the event that the face showing on one die is twice the face showing on the other die.
PABc = 3/36
PABc = 1/12.
Two dice are tossed.
Assume that each possible outcome has 1/36.
Let A be the event the probability of getting some of the faces showing is 6.
A = 1,5,5,12,44,23,3
Let B be the event that the face showing one die is twice on the other.
That is,
B =1,22,12,44,23,66,3
There are 36-6=30 events in Bc
However, A and Bc will only be having 3 pairs together = 1,55,13,3
Therefore,
PABc = 3/36
PABc = 1/12.
How many outcomes are possible for the sum of the faces showing?
There are countless outcomes that could occur. The sum of the faces shown has an endless number of outcomes. This is due to the fact that there are an endless number of ways to flip a coin, which will produce various combinations on the faces that are displayed. The sum of the faces and the tails has an endless number of outcomes. There are only two outcomes that can occur while tossing a coin because the total number of outcomes is always even.

What are the ordered pairs of the solutions for this system of equations? y=x^2-2x+3
y=-5x + 1
The ordered pairs of the solutions for this system of equations is (-2,11) and (-1,6)
Two integers written in a certain order make up an ordered pair. As a result, we may define an ordered pair as a pair of components that appear in brackets and in a specific order.
These equations are composed of a line and a parabola. The intersection points between them must be located:
[tex]y=x^2-2x+3[/tex]
y=-5x+1
Thus,
[tex]x^2-2x+3=-5x+1[/tex]
[tex]x^2-2x+5x+3-1=0[/tex]
[tex]x^2+3x+2=0[/tex]
[tex]x^2+x+2x+2=0[/tex]
[tex]x(x+1)+2(x+1)=0[/tex]
x+2=0, x=-2
x+1=0, x=-1
Since the quadratic expression may be factored out, the following x-values represent the system's solution:
x=-2 and x=-1
Now, we may obtain the corresponding y values using either of the system's original equations. We decide to use a linear equation as an illustration:
When x =-2,
y=11
x=-1,
y=6
Thus the two points solution us (-2,11) and (-1,6)

The missing value is
A. 904
B.9040
C.9240
Answer:
The answer is C
Step-by-step explanation:
The first step is to multiply 154 and 63 to find the product. The product of those two numbers is 9702.
So the the equation looks like...
462+ Blank = 9702
The easiest thing to do here is subtract 462 from both sides. So 9702-462 which would equal 9240.
So we'll say that the blank is x so now the equation says...
x = 9240

The two side pieces on both the right and left hand side are equal in measure. The sides can be parallel only if the sum of both side angles is equal to 180°
Hence,
One side of the interior angle=40º+50º
One side of the interior angle=90°
Both side of the interior angle=90°+90°
Both side of the interior angle=180°

What is dispersion in statistics?Dispersion in statistics refers to how far the data deviates from the mean.When measures of central tendency are insufficient to explain the data, it is highly helpful. Consider the case where the mean is the same across two completely different datasets. Then, in order to explain the variation in the datasets, we employ metrics of dispersion.Now,
The most common examples of statistical metrics of dispersion include:
Standard Deviation: A measurement of how widely apart data are from the mean is the standard deviation. It is the most typical method of measuring dispersion.Interquartile Range: The middle 50% of observations are described by the interquartile range (IQR). The middle 50% of observations are widely separated if the interquartile range is big. Extreme values have no impact on it. Consequently, is helpful when the extreme values are not precisely recorded.Range: The range of data is the distance between the largest and smallest observation. It does not use all of the observations in a data collection and is particularly sensitive to outliers. Therefore, giving the minimum and maximum values rather than the range is more instructive.Hence, The three additional commonly used statistical measures for the characterization of data dispersion are: Standard Deviation, Interquartile Range and Range.

Answer:
f'(1) = -64
Step-by-step explanation:
To find f'(1), we will be finding the f'(x) first which means the first derivative of f(x), we can find the derivative by using chain rule to this function.
The formula of chain rule is:
[tex]\displaystyle f(u) = u^n \to f'(u) = nu^{n-1}\cdot u'[/tex]
In simple explanation, we derive normally (power rule) then multiply by the derivative of inside (u).
Applying the formula, we will have:
[tex]\displaystyle{f'(x)=4(x^2-3)^{4-1}\cdot (x^2-3)'}\\\\\displaystyle{f'(x)=4(x^2-3)^{3}\cdot 2x}\\\\\displaystyle{f'(x)=8x(x^2-3)^{3}}[/tex]
Substitute x = 1 in the f'(x):
[tex]\displaystyle{f'(1)=8(1)(1^2-3)^3}\\\\\displaystyle{f'(1)=8(1-3)^3}\\\\\displaystyle{f'(1)=8(-2)^3}\\\\\displaystyle{f'(1)=8(-8)}\\\\\displaystyle{f'(1)=-64}[/tex]

What is rate of change of a function?To determine the slope of a graphed function, we use the average rate of change formula: Divide the change in y-values by the change in x-values to determine the average rate of change. Identifying changes in measurable parameters like average speed or average velocity calls for the knowledge of the average rate of change.Now,
Given:
For Function A, y = 9x + 4For Function B, rate of change = 4 and y intercept = 4To find: The number of times the rate of change of function A is, as compared to the rate of change of function B.
Finding:
According to the information given,
Rate of change = 3, i.e., b = 3 for function By- intercept = 4, i.e., c = 4Thus, by the slope-intercept form, given by: y = bx + c, the rate of change for function B is given by:
y = 3x + 4
