According to the given statement:
The computed value is significantly less than the given value.
The correct option is B.
What is standard deviation?The standard deviation serves as an indicator of how much a set of values can vary or be dispersed. The values are typically close to the set's mean when the standard deviation is low, while the values are dispersed over a wider range when the standard deviation is high.
According to the given information:The computed value, 14.5
The standard deviation, 11.1
finding the difference :
Percentage = (14.5 - 11.1)/11.1 * 100 = 30.6%
the value is greater than 20%. ,
so,
In comparison to the given value, the computed value is significantly lower.

Bob, Sue, Larry, Sally and Fred are waiting in lime to buy concert tickets.
(1) In how many different ways can they stand in line?
(2) How many ways can they line up if Larry insists on being in the middle?
Answer:
1) 120
2) 24
Step-by-step explanation:
This is a problem involving permutations: the number of different ways you can arrange stuff
If there are n items, n! represents the permutation of n and is given by the formula : 1 x 2 x 3 x........x (n-1) x n also sometimes written in the form
n x (n-1) x (n-2) x........x 3 x 2 x 1
In this case there are 5 people. So the number of different ways they can stand in line is 5! = 5 x 4 x 3 x 2 x 1 = 120 ways Answer to (1)
Answer to (2)
If Larry insists on being in the middle the other 4 have to arrange themselves around Larry in 4! ways = 4 x 3 x 2 x 1 = 24 ways

Answer
A y = 2x + 10

C y = 3x - 9
Dy - 3x + 6
Answer:
Choice D
Step-by-step explanation:
For this one I would find if the point lands on the line.
Choice A:
What we have to do is to plug in -4 for x and 4 for y.
[tex]y=2x+10\\(4)=2(-4)+10\\4=-8+10\\4\ne2[/tex]
The point is not on this line so this cannot be it.
Choice B:
We pug what we know again.
[tex]y=\frac{1}{3}x+1\\(4)=\frac{1}{3}(-4)+1\\(4)=-\frac{4}{3}+1\\4\ne-\frac{1}{3}[/tex]
The point is not on this line so it can't be it.
Choice C:
We pug in what we know again.
[tex]y=3x-9\\(4)=3(-4)-9\\(4)=-12-9\\4\ne-21[/tex]
The point is not on this line so it can't be it.
The next one has to be it, but we'll check it just in case.
Choice D:
We plug in what we know again.
[tex]y= \frac{1}{2}x+6\\(4)=\frac{1}{2}(-4)+6\\(4)=-2+6\\4=4[/tex]
The point is on this line so this is the line.

K is the midpoint of JL. KL= a -24 and JL=48. Find a, JK, and KL.
If K is the midpoint of JL, and (JL = 48), then (JK = KL = 24) and (a = 88).
As per the question statement, K is the midpoint of JL, and (JL = 48).
We are required to calculate the values of JK and KL and, also the value of "a" if [KL = (a - 24)].
Since, K is the midpoint of JL, then K divides JL into two equal line segments, JK and KL.
Therefore, lengths of JK and KL will be [tex]\frac{JL}{2}=\frac{48}{2}=24[/tex], i.e., (JK = KL = 24).
Also, since [KL = (a - 24)],
[tex]24 = (a -24)\\or, a = [24-(-24)]\\or,a = (24+24)\\or,a = 88[/tex]

Problem Solving: The function LaTeX: f\left(x\right)=50x+6500\:f ( x ) = 50 x + 6500represents the amount of money in a bank account over time. The function LaTeX: g\left(x\right)=-25x+9300\:g ( x ) = − 25 x + 9300represents the amount of money in another account over time. Write a rule for the total amount of money in the two accounts over time.
Answer:
25x + 15800
Step-by-step explanation:
Given
The amount of money in both banks over time represented by the functions;
f ( x ) = 50 x + 6500 and g( x ) = − 25 x + 9300
The total amount of money in the two accounts over time is expressed as;
h(x)= f(x) + g(x)
Substitute;
h(x) = 50 x + 6500 + (− 25 x + 9300)
h(x) = 50x - 25x +6500+9300
h(x) =25x + 15800
Hence the sum of the money in the account over time is 25x + 15800

[tex]-\frac{2}{3}[/tex]
Step-by-step explanation:
If I remember correctly, rate of change is basically slope.
So if you want, you can choose two points and use the slope formula. If you're lazy, or don't necessarily NEED to use the slope formula, then you can just choose two points and count the rise and run.
Slope = [tex]\frac{rise}{run}[/tex]
Rise = -2 (going down two)
Run = 3
Therefore the slope is:
[tex]-\frac{2}{3}[/tex]

Step-by-step explanation:
The following are the ages (years) of 5 people in a room: 23 , 19 , 12 , 21 , 13 A person enters the room. The mean age of the 6 people is now 19. What is the age of the person who entered the room?
The age of the person who entered the room is 26.
How to calculate the age?From the information, the ages of the people are
23 , 19 , 12 , 21 , 13. Therefore the addition of the ages will give 88.
When another person entered, the person enters the room, the mean age of the 6 people is now 19. Therefore, the total ages will be:
= 19 × 6
= 114
Therefore, the age of the last person will be:
= 114 - 88
= 26
Therefore, the age of the person who entered the room is 26.

An official playing feild(including end zones) for the indoor football league has a length 27yd longer than its width. the perimeter of the rectangular field is 134yd. find the length and width of the feild
The rectangular field that has a the perimeter of 134yd has a length of 47yd and width of 20yd
To solve this geometry exercise the equation and procedure we will use is:
P = (2*L) + (2*W)
Where:
P= perimeter L= length W= widthInformation about the problem:
P= 134 yd L= x + 27ydW= xApplying the perimeter equation of a rectangle, we have:
P = (2*L) + (2*W)
134 = [2*(x+ 27)] + (2*x)
134 = 2x+ 54 + 2x
134 - 54 = 2x + 2x
80 = 4x
x = 80/4
x = 20
Substituting the value of (x) in the data and we have:
W= x
W= 20yd
L= x + 27yd
L= 20yd + 27yd
L= 47yd

find three consecutive odd integers such that the sum of two times the first, one times the second, and three times the third is 296. list the numbers in order from smallest to largest.
The three consecutive odd numbers in order from smallest to largest are-
1st odd number = 47second odd number = 49third odd number = 51What is consecutive odd numbers?Consecutive numbers are numbers which follow each other in a frequent counting order or pattern.
We all recognize that odd numbers would be those that cannot be totally divided by two. We can see that when we organise them in increasing order, the difference between the two is always 2. The numbers 3, 5, 7, 9, and 11 are examples of consecutive odd numbers so because difference at all between the predecessor-successor pair is 2, as in 5 - 3 = 2 and 7 - 5 = 2.Now, as per the question;
Let the first odd number be 'n'.
Then, the second odd number will be '(n + 2)'.
And, the third odd number will be '(n + 4)'
Now, we have to take the two times the first = 2n.
one times the second = (n + 2)
three times the third = 3(n + 4).
Sum of all three is 296.
Thus,
2n + (n + 2) + 3(n + 4) = 296
Simplifying the equation;
2n + n + 2 + 3n + 12 = 296
6n = 296 - 14
6n = 282
n = 47 (1st odd number)
n +2 = 47 + 2 = 49 (second odd number)
n + 4 = 47 + 4 = 51 (third odd number)
Thus, the three consecutive odd numbers has be calculated.

How does an equation shows a relationship between variables and other quantities in a solution
An equation shows the relationship between variables and other quantities in a situation, by equating the constraints of the situation.
The variable is the unknown part of the equation that can take any value according to the equation.
Properties of an equation can be defined as-
They are the expression which consist the variables, coefficients of variables and constants having an equal sign in between.
The example of an equation can be given as:
y = 5 x + 10
Lets assume here that the variable (y) represent the charge of taxi and variable (x) represent the number of rides the taxi traveled.
Here the constant 10 is the fixed amount which is charged by the taxi driver and coefficient of (x) 5 is the rate by which the the value of x increases with respect to y.
Therefore, an equation shows the relationship between variables and other quantities in a situation, by equating the constants of the situation.

Use the Distributive Property to solve the equation below. Use pencil and paper. Describe what it means to distribute the 4 to each term inside the parentheses. 4(m+4)=28
Answer: m=3
Step-by-step explanation:
Distributing the '4' means multiplying it by everything within the parenthesis next to it. That means, in this circumstance, you are multiplying the 'm' and the '4' by the '4' on the outside the parenthesis.
4(m+4)=28
4m+16=28. Subtract the 16 on both sides.
4m=12
