The option that is true about opposite numbers is; Option D: Point B and Point G are opposite rational numbers because they are the same distance away from zero.
What are the Opposite Numbers?Opposite numbers are numbers that, when placed on a number line, are the exact same distance away from the 0, but on opposite sides, or in opposite directions.
We are given the points on the number line as;
A = -3/2
B = -4/3
C = -3/4
D = -2/3
E = 2/3
F = 3/4
G = 4/3
From the above, we can tell that;
Points B and G are opposite numbers
Points C and F are opposite numbers
Points D and E are opposite numbers
Looking at the given options, the only correct one is; Option D: Point B and Point G are opposite rational numbers because they are the same distance away from zero.

A random number generator will pick a whole number from 1 to 20 ten times. Predict how many times you think it will pick two numbers that are 8 or less. Explain.
The prediction of the number of times it will pick two numbers that are 8 or less is 4 times
How to predict the number of times it will pick two numbers that are 8 or less?The given parameters are
Sample space = Whole number from 1 to 20Number of trials, n = 10Probability values: Values that are 8 or lessThe sample size of whole number from 1 to 20 is
Sample Size = 20
While the sample size of the probability values that are 8 or less is
Probability Size = 8
So, the probability of selecting a value that is 8 or less is
P = Probability Size/Sample Size
So, we have
P = 8/20
The prediction of the number of times it will pick two numbers that are 8 or less is
Prediction = P * n
So, we have
Prediction = 8/20 * 10
Evaluate the product
Prediction = 4
Hence, the prediction of the number of times it will pick two numbers that are 8 or less is 4 times

Jaun's age, x, is 4 times his age 15 years ago
The expression of the mathematical statement given as "Jaun's age, x, is 4 times his age 15 years ago" is x = 4 * (x - 15)
How to rewrite the statement as an expression?The mathematical statement is given as
Jaun's age, x, is 4 times his age 15 years ago
From the statement, we have:
x represent Juan's current age
This means that his age 15 years ago is
15 years ago = x - 15
4 times his age 15 years ago is
4 * 15 years ago = 4 * (x - 15)
The above equation is equivalent to his current age
So, we have
x = 4 * (x - 15)
Hence, the expression of the mathematical statement given as "Jaun's age, x, is 4 times his age 15 years ago" is x = 4 * (x - 15)

Answer: x =
Answer:
A) 2 + 8x = -134
B) x = -17
Step-by-step explanation:
Note: I am assuming the question says use x as a variable, not z. Otherwise part B does not make sense
If we let variable x be the number then
8 times a number ==> 8x
2 and 8 times a number ==> 2 + 8x
2 and 8 times a number is -134 ==> 2 + 8x = -134
A) Equation form is 2 + 8x = -134
B) Equation is
2 + 8x = -134
Subtract 2 from both sides:
2 - 2 + 8x = -134 - 2
8x = -136
Divide both sides by 8 to give
8x/8 = -136/8
x = - 17

Among the four options provided in the reference diagram for the question attached thereby along with the question statement, {(-5, 8), (-5, 2), (-3, 3), (-3, 1), (0, 4), (0, 5), (-5, 7), (-3, 6)} is the relation that has a domain of {(-5), (-3), 0} and a range of {1, 2, 3, 4, 5, 6, 7, 8}.
As per the question statement, we are required to determine the relation which has a domain of {-5, -3, 0) and a range of {1, 2, 3, 4, 5, 6, 7, 8).
To solve this question, we will use the trial-and-error method on the options provided. We have to find out possible (x, y) combination, where "x" belongs to the set of {(-5), (-3), 0} and "y" belongs to the set of {1, 2, 3, 4, 5, 6, 7, 8}, and match these combinations with the options.
The first option has x values from the set of {1, 2, 3, 4, 5, 6, 7, 8} and y values from the set of {(-5), (-3), 0}. Hence, it is not the correct answer.
The second option has x values from the set of {(-5), (-3), 0} and y values from the set of {1, 2, 3, 4, 5, 6, 7, 8}. Hence, it is one possible correct answer.
The third and fourth options have values out of the sets of {(-5), (-3), 0} and {1, 2, 3, 4, 5, 6, 7, 8}. Hence, they are not the correct answers.
Therefore, {(-5, 8), (-5, 2), (-3, 3), (-3, 1), (0, 4), (0, 5), (-5, 7), (-3, 6)} is the relation that has a domain of {(-5), (-3), 0} and a range of {1, 2, 3, 4, 5, 6, 7, 8}.

The value of the probability of hitting the target is 0.1736.
According to the statement
We have to find that the value of the probability.
So, For this purpose, we know that the
Probability is the branch of mathematics that studies the possible outcomes of given events together with the outcomes' relative likelihoods and distributions.
From the given information:
A circular dartboard with a diameter of 24 inches has a circular bullseye at its center. The diameter of the target is 10 inches.
Then
Area of a circular dartboard = [tex]\pi r^{2}[/tex]
Area of a circular dartboard = [tex](3.14)* 12^{2}[/tex]
Area of a circular dartboard = [tex](3.14) *144[/tex]
Area of a circular dartboard = 452.16 inches
And then
Area of a circular bullseye = [tex]\pi r^{2}[/tex]
Area of a circular bullseye = [tex](3.14)* 5^{2}[/tex]
Area of a circular bullseye = [tex](3.14) * 25[/tex]
Area of a circular bullseye = 78.5
Then
Probability of hitting the target = Area of a circular bullseye / Area of a circular dartboard
Probability of hitting the target = 78.5 / 452.16
Probability of hitting the target = 0.1736.
So, The value of the probability of hitting the target is 0.1736.

A dinner set can be bought for $110000 cash or by a deposit of $37000 and 24 equal monthly installments of $4600 each. How much more will the dining set cost using the hire purchase method of payment?
The difference between the dining set cost using the hire purchase method of payment is $37400.
How to calculate the cost?It should be noted that when the hire purchase is used and there is a deposit of $37000 and 24 equal monthly installments of $4600 each.
The total amount will be:
= $37000 + ($4600 × 24)
= $37000 + $110400
= $147400
On the other hand, the dinner set can be bought for $110000 cash.
Therefore, the difference will be:
= Hire purchase - Cash.
= $147400 - $110000.
= $37400
Therefore, the difference between the dining set cost using the hire purchase method of payment is $37400.

The value of x is 6 is proved by equating line segment PM and MR as M is the midpoint of line PR.
What is midpoint of line segment?
The midpoint divides the line segment into two equal parts. As the number line progresses, the leftmost numbers become smaller, and the rightmost numbers become larger. Adding, subtracting, and multiplying can also be done using a number line like for addition move towards right and for subtraction move towards left.
It is given that M is the midpoint of line segment PR which implies M will divide PQ into two equal parts that is PM (2x + 5) equals MR (4x - 7). now calculating x value first :
PM = MR
2x+5 = 4x -7

Put both equations in the same format
x - 6y = 2
Manipulate the equations so that they have a common coefficient
6y = 30
Solve for one coefficient
(x - 6y = 2) + (6y = 30)
x + (-6y + 6y) = 2 + 30
x = 2 + 30
x = 32
Solve for the other coefficient
