hello can you help me to understand this. 4 (18) it's 2 dots (19) 3 dots (20) 6 dots (21) 4 dots (22) 1 dots (23) 1 dot (24) ??? I don't get it
Explanation
to plot this, you need to count the numbers of weigth for that number, for example
for 18
count in the table all the 18
you will get 18 is 2 times in the table (2)
now, for 19
count the number of 19's in the table 3
and so on
Step 1
then, for 24
total = 0
so, as we have not 24 as a data, there is not need to plot it
I hope this helps you
Using the midpoint and distance formulas, calculate the coordinate of the midpoint and the length of the segment.
The midpoint formula [tex]\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2}[/tex] and the length of coordinates can be determined from the formula [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex].
What are coordinates?
Coordinates are a pair of integers (Cartesian coordinates), or sporadically a letter and a number, that identify a certain place on a grid, also referred to as a coordinate plane.
The x-axis & y-axis are the two axes that make up a coordinate plane (vertical).
The coordinates of the origin, which is the location where the two axes connect, are (0, 0).
The following formula is used to determine the separation between two coordinates :

What is midpoint of a segment?
The midpoint of a vertical line is known as the midpoint in geometry. It is the centroid of the segment and of the ends, and it is equal to the distance from both of them. It cuts the section in half.A midpoint is the position that is in the middle or center of a line connecting two points, often referred to as endpoints. The midpoint formula can be used to determine the other midpoint given one endpoint and a midpoint.The midpoint of AB = ( – 5, 4) = ( x ,y)
A = (0, – 9) ⇒ ( x₁ , y₁)
Let B = ( x₂, y₂ )
midpoint of AB ⇒ x = x₁ + x₂/2 , y = y₁ + y₂/2

Suppose a diver jumps from a ledge that is 115 feet above the ocean and the initial upward velocity is 8 feet per second. The vertical motion of the diver can be modeled by the function h = −t^2 + 8t + 115. How long will it take until the diver enters the water? How do you know?
The given function of the height of the diver is
[tex]h=-t^2+8t+115[/tex]h is the height in feet
t is the time in seconds
To find the time for the whole motion equate h by 0, as when the diver inter the water his jumper height will be zero. (The surface of the water is the initial position)
[tex]0=-t^2+8t+115[/tex]Switch the 2 sides and change all signs to opposite

The probability of a student eating at the cafeteria and a student living off campus is 0.07, and the probability of a student eating at the cafeteria given that the student lives off campus is 0.20, what is the probability of a student living off campus?
The probability of a student living off campus is 0.35.
What is the probability?It should be noted that probability simply means the likelihood that something will occur.
Remember the multiplication rule for conditional probability: P(B AND A)=P(B/A)P(A)
Rearranging, we find that P(A)=P(B AND A)P(B/A)
So if we think of A= the event a student lives off campus and B = event a student eats at the cafeteria, then we can plug in the known information to find:
P(A)=0.07 / 0.20

What would be the first step when solving using the substitution method?
2x + 3y = -12
x = 3y + 3
The first step of substitution method for given system is put x = 3y +3 in place of x into the equation 2x+3y=-12 .
What is the method of substitution for system of equation in two variables ?The system of the equations in two variables x and y consists of two equation of the form a₁ x + b₁ y = c₁
and a₂ x + b₂ y = c₂
where a₁, a₂, b₁, b₂ , c₁, c₂ are constants
For substitution method, first expression of one variable is found from one equation and then put this expression in another equation to create a linear equation in second variable. Solve the linear equation in one variable for second variable and then put the value of second variable in first equation to solve for first variable
Given system of equations is :
2x + 3y = -12 .....(1)
x = 3y + 3 .....(2)
So the first step will be take expression for one variable from one equation and put it into another equation.
Take x = 3y +3 which is an expression for x from equation (2),
Then put it into equation (1)
⇒ 2 (3y +3 ) + 3 y = -12 , This is the first step of substitution method for this variable

After making your 20th payment of $524.50 on your car loan, you wanted to find out how much is left of your original 5 years loan at 6.2% compounded monthly of $27,000.00. What is the amount of the remaining balance of your car loan?
The amount of the remaining balance of the car loan is $26293.1103.
Given,
The initial loan amount, P = 27000
The rate of interest, r = 6.2%
Time period, t = 5 years
Interest is compounded monthly.
The 20th payment of the loan = $524.50
We have to find the remaining balance of the car loan.
Here,
Amount, A = P[1 + r/n]^nt
Where,
A is the total amount = principal amount + compound interest
P is the principal amount
r is the rate of interest
n is the number of times compounded
t is the time period
So,
A = P[1 + r/n]^nt
A = 27000 × [1 + 6.2/100/12]^12 × 5
A = 27000 × [12.062/12]^60
A = 27000 × [1.005166]^60
A = 27000 × 1.362
A = 36783.1103
The total amount should be paid after 60 months is $36783.1103
Now,
The 20th payment = $524.50
That is,
524.20 × 20 = 10490
$10490 is paid and the balance amount;
36783.1103 - 10490 = 26293.1103
Therefore,
The amount of the remaining balance of the car loan is $26293.1103.

A space shuttle is moving in a straight line and is traveling at a constant speed. It takes 3 hours to get from A to B and 1 hour to get from B to C. Relative to a suitable set of axes, A is the point (4,-1,7) and B is the point (16,-10,10). Find the coordinates of C.
We will solve as follows:
First: We will use the i, j, k vector notation to describe each point as a vector:
[tex]A=4i-j+7k[/tex][tex]B=16i-10j+10k[/tex]Now, we have that the time it takes to get from A to B is 3 hours (t1). And the time it takes from B to C is 1 hour (t2).
Second: We determine the speed from A to B:
[tex]v=\frac{B-A}{t_1}\Rightarrow v=\frac{(16-4)i+(-10+1)j+(10-7)k}{3}[/tex][tex]\Rightarrow v=\frac{12i-9j+3k}{3}\Rightarrow v=4i-3j+k[/tex]Third: We now determine the value of C:
[tex]C=B+vt_2\Rightarrow C=(16+4)i+(-10-3)j+(10+1)k[/tex][tex]\Rightarrow C=20i-13j+11k[/tex]So, we would have that the coordinates of C are:
