Using an 8 sector spinner, let E be the event of getting an even. What is the probability of getting a perfect square given you got an even, i.e. P(S/E)? Are the two events independent or dependent?
Answers
Two events are dependent since the probability of getting a perfect square is affected by the fact that we already know that we got an even number.
Describe Probability?Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, where 0 indicates that the event is impossible and 1 indicates that the event is certain. For example, the probability of rolling a 6 on a fair dice is 1/6, or approximately 0.167.
In probability theory, events are often expressed as sets of possible outcomes, and probabilities are calculated based on the number of outcomes in the event relative to the total number of possible outcomes. For example, the probability of rolling an even number on a fair dice is 3/6, or 0.5, because there are three even numbers (2, 4, and 6) out of a total of six possible outcomes.
Since the event E is the event of getting an even number, the possible outcomes are 2, 4, 6, or 8.
Out of these, only 4 is a perfect square. Therefore, P(S/E) = 1/4.
These two events are dependent since the probability of getting a perfect square is affected by the fact that we already know that we got an even number.

Order each triangle from shortest to longest. NO LINKS!!!!
Answers
Answers:
Problem 15) RS, RT , STProblem 16) BD, CD, BCThe side lengths are sorted from shortest to longest.
====================================================
Explanation:
For any triangle, the smallest side is opposite the smallest angle. Similarly, the largest side is opposite the largest angle.
With this in mind, for problem 15, the smallest side is side RS, due to angle T = 50 being the smallest angle. We don't know the value of side RS (nor the other sides so we can numerically compare them), but we don't need this info since the rule mentioned in the first paragraph is sufficient. You could use the law of cosines to help confirm the rule is true.
Also for problem 15, the longest side is side ST. This is because the opposite angle to this side is R = 70, which is the largest angle of the trio.
-------------
In problem 16, the shortest and longest sides are BD and BC respectively. This is because C = 50 and D = 70 are the smallest and largest angles (in that order) and these angles are opposite the mentioned sides in bold.

The retail price of a television set is $4,500. If the buyer pays by cash, the price is 10% below the retail price. If the set is bought on higher purchase, the buyer pays a down payment of $675 and 24 monthly installments of $212.50. Calculate for the television the:
cash price to the buyer, if he pays by cash.
amount payable.
outstanding balance.
hire purchase price.
interest.
difference between the hire purchase and the cash price.
percentage interest charged.
Answers
Cash price to the buyer, if he pays by cash:
The cash price would be 10% less than the retail price of $4,500:
Cash price = $4,500 - (10% * $4,500)
Cash price = $4,500 - $450
Cash price = $4,050
Amount payable:
If the buyer chooses to purchase the TV on higher purchase, the amount payable would be the sum of the down payment and the total amount of monthly installments:
Amount payable = Down payment + (24 * Monthly installment)
Amount payable = $675 + (24 * $212.50)
Amount payable = $5,175
Outstanding balance:
The outstanding balance would be the difference between the amount payable and the down payment:
Outstanding balance = Amount payable - Down payment
Outstanding balance = $5,175 - $675
Outstanding balance = $4,500
Hire purchase price:
The hire purchase price would be the sum of the down payment and the outstanding balance:
Hire purchase price = Down payment + Outstanding balance
Hire purchase price = $675 + $4,500
Hire purchase price = $5,175
Interest:
The interest charged on the hire purchase would be the difference between the hire purchase price and the cash price:
Interest = Hire purchase price - Cash price
Interest = $5,175 - $4,050
Interest = $1,125
Difference between the hire purchase and the cash price:
The difference between the hire purchase price and the cash price would be the interest charged:
Difference = Interest
Difference = $1,125
Percentage interest charged:
To calculate the percentage interest charged, we can divide the interest by the hire purchase price and multiply by 100:
Percentage interest charged = (Interest / Hire purchase price) * 100
Percentage interest charged = ($1,125 / $5,175) * 100
Percentage interest charged = 21.74%
Therefore, the cash price to the buyer is $4,050, the amount payable is $5,175, the outstanding balance is $4,500, the hire purchase price is $5,175, the interest charged is $1,125, the difference between the hire purchase and the cash price is $1,125, and the percentage interest charged is 21.74%.

Answers
Answer:
C. True; by the Invertible Matrix Theorem if the equation Ax=0 has only the trivial solution, then the matrix is invertible. Thus, A must also be row equivalent to the n x n identity matrix.
Step-by-step explanation:
The Invertible matrix Theorem is a Theorem which gives a list of equivalent conditions for an n X n matrix to have an inverse. For the sake of this question, we would look at only the conditions needed to answer the question.
There is an n×n matrix C such that CA=\(I_n\).There is an n×n matrix D such that AD=\(I_n\).The equation Ax=0 has only the trivial solution x=0.A is row-equivalent to the n×n identity matrix \(I_n\).For each column vector b in \(R^n\), the equation Ax=b has a unique solution.The columns of A span \(R^n\).Therefore the statement:
If there is an n X n matrix D such that AD=I, then there is also an n X n matrix C such that CA = I is true by the conditions for invertibility of matrix:
The equation Ax=0 has only the trivial solution x=0.A is row-equivalent to the n×n identity matrix \(I_n\).The correct option is C.

Graph that line with slope -1 passing through the point (-2,4)
Answers
Answer:
To graph the line with slope -1 passing through the point (-2,4), we can use the point-slope form of the equation of a line, which is:
y - y1 = m(x - x1)where m is the slope of the line, and (x1, y1) is the given point on the line. Substituting the given values, we get:
y - 4 = -1(x - (-2))Simplifying this equation, we get:
y - 4 = -x - 2y = -x + 2Now we can graph this line by plotting the given point (-2,4), and then using the slope of -1 to find one or more additional points on the line. We can do this by starting at the given point and then moving one unit down (since the slope is negative) and one unit to the right (since the slope is -1). This gives us the point (-1,3). We can then connect these two points to graph the line.

Think About the Process You have 30 quarters. You find 20% more quarters in your room. Then you go shopping and spend 50% of the total number of quarters. Write an expression to represent the total number of quarters you take with you shopping. Calculate, in dollars, the amount of money you have left.
Answers
Answer: $4.5 left.
Step-by-step explanation:
You have 30 quarters, and find 20% more. To convert percentages to decimals for calculations, simply move the decimal two spaces to the left.
20% is 20. ---> 2.0 ---> .20
30 * 0.2 = 6. Now add 6 (found) to 30 (original) to get the total.
30+6 = 36 total quarters.
You spend 50% of the quarters, 36 * 0.5 = 18.
This means you have 18 quarters left (or you spent 18).
18 quarters, each quarter is worth 0.25 dollars, so multiply the number left by how much each is worth.
18 * 0.25 = $4.5.
$4.50 is the amount left

Number on ants on Earth = 1.2 × 10¹⁵
Step-by-step explanation:
1 quintillion = 10¹⁸ or (1000000000000000000)
∴ 12 quintillion = 12 × 10¹⁸
12 quintillion = 10,000 × Number of ants on Earth
Let the number of ants on Earth = n
12 quintillion = 10,000 × n
dividing both sides by 10,000
12 quintillion ÷ 10,000 = n
\(n = \frac{12\ \times\ 10^{18} }{10,000} \\n = \frac{12\ \times\ 10^{18} }{10^{4}}\\n = 12\ \times\ \frac{10^{18}}{10^{4}} \\applying\ the\ second\ law\ of\ indices\ (\frac{x^m}{x^n} = x ^{m-n})\\ n = 12\ \times\ 10^{(18 - 4)\\n = 12\ \times 10^{14}\\in\ standard\ form\\n = 1.2\ \times 10\ \times\ 10^{14}\\\therefore n = 1.2\ \times\ 10^{15}\)

What is the slope of the line that passes through the points (-2,8) and (-22,8)? Write your answer in simplest from
Answers
Answer:
\(\boxed{\tt m=0}\)
Step-by-step explanation:
The slope formula is:
\(m=\frac{y_{2} -y_{1}}{x_{2}-x_{1}}\)
where (x₁, y₁) and (x₂,y₂) are the points on the line.
The points given are (-2,8) and (-22,8). Therefore,
\(x_{1}=-2\\y_{1}=8\\x_2=-22\\y_2=8\)
Substitute the values into the formula.
\(m=\frac{8-8}{-22--2}\)
Solve the numerator. Subtract 8 from 8.
\(m=\frac{0}{-22+2}\)
Zero divided by any number is zero, so we automatically know the slope is zero.
\(m=0\)
The slope of the line is 0
Answer: 0
Step-by-step explanation:
To find the slope, you need to use the formula \(m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\). You use the given points to plug in and solve.
\(m=\frac{8-8}{-22-(-2)} =\frac{0}{-20}=0\)
Now, we know that the slope is 0 meaning this is a horizontal line.

The theorem is expressed as follows:
c² = a² + b².
In which:
c is the length of the hypotenuse.a and b are the lengths of the other two sides (the legs) of the right-angled triangle.Considering the geometric mean theorem, the triangle has bases of 7 and 14 - 7 = 7, hence the altitude BD is given as follows:
BD² = 7 x 7
BD² = 7²
BD = 7.
The segment BC is the hypotenuse of a right triangle of two sides with length 7, hence:
