A bag has six balls labeled A, B, C, D, E , F.
One ball will be randomly picked, and its letter will be recorded as the outcome.
Give the sample space describing all possible outcomes. Then give all of the outcomes for the event of choosing a letter from D to F.
If there is more than one element in the set, separate them with commas.
Answers
The sample space for the events are given as follows -
Picking up a one ball randomly from six balls -
S [1] = {A, B, C, D, E , F}
Picking up a one ball randomly from balls D to F -
S [2] = {D, E , F}
What is Probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur.
Given in the question a bag has six balls labeled A, B, C, D, E , F and one ball is randomly picked.
Sample space is defined as the set of all the outcomes for a given event. In the question given, the event is picking up of a ball randomly. A total number of six balls are there in the bag. Therefore, if a ball is picked up randomly, it could be any of the six. Therefore - the sample space for this event will be -
S [1] = {A, B, C, D, E , F}
Now, for the event of choosing a letter from D to F, we have total three outcomes. So in this case the sample space will be -
S [2] = {D, E , F}
Therefore, the sample space for the events are given as follows -
Picking up a one ball randomly from six balls -
S [1] = {A, B, C, D, E , F}
Picking up a one ball randomly from balls D to F -
S [2] = {D, E , F}

3. For the sequence
60, 90, 135, 202.5 ...
A. Find the next term (write your answer as a decimal):
B. Is the sequence arithmetic or geometric?
C. Write a recursive function for the sequence.
Answers
a. The next term in the sequence is 303.75.
b. The sequence is a geometric sequence.
c. The recursive function for the sequence is: aₙ = aₙ₋₁ (1.5) for n≥2.
Given the sequence is : 60,90,135,202.5,....
a. the next term in the sequence is:
Find the common ratio by dividing any term in the sequence by the term that comes before it:
a₂/a₁ = 90/60 = 1.5
a₃/a₂ = 135/90 = 1.5
a₄/a₃ = 202.5/135 = 1.5
The common ratio (r) of the sequence is constant and equals the quotient of two consecutive terms.
r = 1.5
find the sum:
To find the sum of the series, plug the first term: a = 60, the common ratio(r): 1.5 and the number of elements n = 4 into the geometric series sum formula:
Sₙ = a(1₋rⁿ/1₋r)
Sₙ = 60(1 ₋ 1.5⁴/1₋1.5)
Sₙ = 60(1 ₋ 5.0625/1₋1.5)
S₄ = 60(8.125)
S₄ = 478.5
To find the general form of the series, plug the first term:
aₙ = 60×1.5ⁿ⁻¹
use the general form to find the next term:
a₁ = 60
a₂ = a₁rⁿ⁻¹ = 60(1.5)¹ = 90
a₃ = a₁rⁿ⁻¹ = 60(1.5)² = 135
a₄ = a₁rⁿ⁻¹ = 60(1.5)³ = 202.5
a₄ = a₁rⁿ⁻¹ = 60(1.5)⁴ = 303.75
hence the required next term is 303.75
(b) The above sequence is geometric sequence.
(c) recursive function for the sequence : aₙ = aₙ₋₁ (1.5) for n≥2.
Hence we get the required answers.

The value of term a11 is 21k - 43.
How to find the value of term a9?The difference between any two consecutive integers in an arithmetic progression (AP) sequence of numbers is always the same value.
The formula of Arithmetic progression is

a) $17.25
b) $23.50
c) $75.00
d) $200.00
Answers
The amount that you earned last month would be the total of $17.25
How to solve for the earningWe have the following data
online pay bill per month = 50
The monthly online deposit = 50
The points that are made per car payment = 100
The point that is made per credit card = 1.5 points
The monthly credit card charges of $1,400
The monthly point would be 1400 * 1.5 = $2100
We have to solve for the total points
= 50 + 50 + 100 + 2100
= 2300
We have $75 per 10,000
For 2300 points, this would be 75/10000 * 2300

The mean test score of 10 students is 50 marks.
A student joins the class.
The mean of all 11 students is now 55 marks.
Find the test score of the student who joined the class.
Answers
Answer:
105.
Step-by-step explanation:
Total score for 10 students = 50 * 10 = 500.
When 1 student joins:
mean score = (500 + x) / 11 = 55 where x is the test score of the new student.
500 + x = 55 * 11
x = 55*11 - 500
= 605 - 500
= 105.
In the given case , we can conclude The test score of the student who joined the class is 105 marks.
Let's solve this problem step by step:
The mean test score of the first 10 students is 50 marks. Therefore, the total marks scored by these 10 students is 10 x 50 = 500 marks.
When the new student joins, the mean score of all 11 students becomes 55 marks.
Therefore, the total marks scored by all 11 students is 11 x 55 = 605 marks.
To find the test score of the new student, we subtract the total marks of the first 10 students from the total marks of all 11 students: 605 - 500 = 105 marks.
Therefore, the test score of the student who joined the class is 105 marks.

The perimeter of a circle or an ellipse in geometry is known as the circumference. That is, if the circle were opened up and straightened out to a line segment, the circumference would be the length of the arc. The curve length around any closed figure is more often referred to as the perimeter. The term "circumference" can also refer to the circle's actual location, which corresponds to a disk's edge.
The circumference of a circle is calculated by the formula 2πr .
The given coordinates are A(2,3) and B(4,1)
Here A is the center of the circle and B is any point on the circumference.

Answers
The initial amount and rate of change given a table for a linear function are $1160 and -$30, respectively
How to find the initial amount and rate of change given a table for a linear function?The table of linear function represents the given parameter
On the table, we have the following points
(x, y) = (6, 980) and (12, 800)
The rate of change is calculated as
Rate = (y2 - y1)/(x2 - x1)
So, we have
Rate = (980 - 800)/(6 - 12)
Evaluate
Rate = -30
This means that the rate of change is -$22.5
The initial amount is calculated as
y = m(x - x1) + y1
Where
m = -30
So, we have
y = -30(x - x1) + y1
Using one of the points, we have
y = -30(x - 6) + 980
Set x = 0
So, we have
y = -30(0 - 6) + 980
Evaluate
y = 1160
Hence, the initial amount and rate of change given a table for a linear function are $1160 and -$30, respectively

Notice that the given series is an arithmetic series with:
first term, a(1) = -5
common difference, d = -25 - (-5) = -20

b. What information can you get from the function to find the maximum volume?
Answers
The dimension that give the maximum volume will be the sides.
The volume will be 324cm³.
How to calculate the value?It should be noted that the maximum value is when the rectangle is a square.
Let s be the side of the square.
The perimeter will be 4s.
Solving for s:
= 36/4
= 9cm
It should be noted that area = s²
where s = side
= 9² = 81cm
Therefore, the volume will be
= Area × Side
= 81 × 4
= 324cm³

What's total amount of rope that extends to the two stakes supporting tree in trigonometry?
Answers
According to the question, the total amount of rope needed to extend the two stakes supporting the tree in trigonometry can be determined by using the functions sine and cosine.
Explain trigonometric function with example.
If the rope can be tied with the tree trunk then the staked rope makes an angle with respect to the ground. And it can be calculated with the help of the trigonometric functions. And it states that the ratio of the length of the opposite sides and the hypotenuse of the right angle triangle. And the result of the ratio is sine function.
Therefore, the total amount of two ropes needed so that it extends to the two stakes of the supporting trees.

x+3y = 7 , 2x - 4y = 24
Answers
By substitution, the solution of the system of equations, x + 3y = 7 and 2x - 4y = 24, is (10 , -1).
A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.
There are three methods that can be used to solve system of linear equations.
1. Elimination
2. Substitution
3. Graphing
Using substitution method, given two linear equations in x and y,
x + 3y = 7 (equation 1)
2x - 4y = 24 (equation 2)
Using the first equation, find the value of one variable, lets say x, in terms of the other.
x + 3y = 7 (equation 1)
x = 7 - 3y
Substitute the equation of x to the second equation.
2x - 4y = 24 (equation 2)
2(7 - 3y) - 4y = 24
14 - 6y - 4y = 24
Combining all terms containing the variable y on one side and the constants on the other side of the equality, and solving for y.
14 - 6y - 4y = 24
-6y - 4y = 24 - 14
-10y = 10
y = -1
Substitute the value of y in the equation of x.
x = 7 - 3y
x = 7 - 3(-1)
x = 7 - (-3)
x = 10
Hence, the solution of the given system of equations is (10 , -1).
