What is fraction ?Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English.
An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a correct fraction is smaller than the denominator.
The three main sorts of fractions are as follows. Proper fractions, improper fractions, and mixed fractions are these three types. The expressions with a numerator and a denominator are called fractions. We categorize its kinds based on these two parameters.
The fractions are x/3y, x/6y and z(say)
so sum of all the fraction must be 1 so
x/3y + x/6y + z = 1
⇒z = (2y-x)/2y
The third girl recieve a land area equals to (2y-x)/2y.

The cost of manufacturing a particular videotape is C(x) = 9000 + 9x, where x is the number of tapes produced. The average cost per tape, denoted by overbar(C)(x), is found by dividing C(x) by x. Find (x→9000) is under (lim)overbar(C)(x).
The average cost per tape is 10.
What is average cost?The average cost is the ratio of the total of cost of all the products to the total number of products. We can calculate the average cost by dividing the total cost by the total output quantity.
The cost of manufacturing a particular videotape is :
C(x) = 9000+9x
Where
x is the number of tapes produced.
We need to find the value of average per tape i.e. lim x →9000 C (x)
C (x) = 9000 + 9x
x
= 9000 + 9
x
Lim n→ 9000 C (x) = 9000 +9
9000
= 1 + 9
= 10
So, the average cost per tape is 10

In a certain bag, the ratio of red to green to blue marbles is 1:2:3 . There are 5 red marbles. How many blue marbles are there?
Explanation
The ratio 1:2:3 refers to the idea we could have: 1 red, 2 green, 3 blue. The order of the colors is important. Follow the order mentioned in the 1st sentence of the instructions. That order being red:green:blue.
Then the instructions mention that there are actually 5 red (instead of 1 red). This means we multiply each part of the ratio by 5
1*5 = 5 red2*5 = 10 green3*5 = 15 blueThe ratio 1:2:3 scales up to 5:10:15
We see that there are 15 blue marbles
Hannah makes 5 out of 8 attempted free-throws! What is the average waiting time for Hannah to make her first basket, and what is the probability that she will make a basket on or before her last attempt within her average waiting time?
The probability that she will make a basket on or before her last attempt within her average waiting time are 1/8 and 2/8
How can we interpret probability?Probability of an event is a measurement of how likely an event can occur as an outcome of a random experiment.
Probability ranges from 0 to 1, both inclusive. Events whose probability is closer to 0 are rarer to occur than those whose probabilities are closer to 1 (relatively).
When converted to percentage, we just need to multiply its decimal representation by 100. In percentage form, the probability ranges from 0% to 100%.
Given;
Hannah makes 5 out of 8 attempted free-throws
Now,
The average waiting time of hannah to make her first basket=5/8
The probability of hannah making basket at her last attempt=1/8
The probability of hannah making basket before her last attempt= 2/8

The sampling method used was random sampling.
What was the sampling method used?This sample may not be representative of the entire class as it does not consider the individual characteristics of the students and only takes into account the row that they are seated on.
Additionally, there is a potential for bias as the sample size is quite small and may not accurately reflect the overall population. Therefore, it would be beneficial to use a larger sample size or use a stratified random sampling method to ensure a representative sample.
The sampling method used was random sampling.
This sample is likely to be representative, as it was chosen randomly and evenly from the seating chart. However, there could be potential issues if the student's Exam 1 scores are not evenly distributed among the rows.
For example, if all the higher scores are concentrated in one row, then the sample may not be representative of the entire class. To ensure an accurate estimation of the average Exam 1 score for the entire class, it may be better to use stratified sampling, where each row is given equal weight and students are selected from each row with the same probability.

Let us choose some number t and consider a point A(2t+3,24t+1).Prove that all such points make a line.What is the slope and the y intercept of this line?
The parametric vector represents a line, whose slope and intercept are 12 and - 35, respectively.
How to analyze and interpret parametric functions
Parametric functions are multi-dimensional functions in terms of a variable t that is a real number. In this problem we find a parametric function with coordinates, that is, a vector of the form (x, y) = (f(t), g(x)) and we are supossed to determine the rectangular form of such function, that is, a function of the form:
y = f(x)
The rectangular form of the function is a line if and only if the resulting expression is of the form:
y = m · x + b
Where:
m - Slopeb - Interceptx - Independent variabley - Dependent variableFirst, write the components of the parametric functions:
x = 2 · t + 3
y = 24 · t + 1
Second, clear variable t in each parametric expression:
t = (x - 3) / 2
t = (y - 1) / 24
Third, eliminate parameter t by transitive property:
(x - 3) / 2 = (y - 1) / 24
Fourth, obtain the equation of the line:
24 · (x - 3) = 2 · (y - 1)
24 · x - 72 = 2 · y - 2
24 · x - 70 = 2 · y
y = 12 · x - 35
Fifth, determine the slope and intercept of the equation of the line:
m = 12, b = - 35

Consider a pool of six I/O buffers. Assume that any buffer is just as likely to be available or occupied as any other. Compute the probabilities associated with the following events:
A = At least two but no more than five buffers occupied.
B = At least three but no more than five buffers occupied.
C = All buffers available or an even number of buffers occupied.
D = At least one of the events A, B, and C occurs.
The associated probabilities are A = At least two but no more than five buffers occupied.
There are a total of 2^6 = 64 possible outcomes when rolling 6 dice.
To find the probability of event A, we need to find the number of outcomes where at least two but no more than five buffers are occupied.
This can be done by summing the probabilities of each individual outcome where two, three, four, or five buffers are occupied and subtracting the probabilities where six or zero buffers are occupied.
The probability of two buffers being occupied is (6 choose 2)(1/64) = 15/64
The probability of three buffers being occupied is (6 choose 3)(1/64) = 20/64
The probability of four buffers being occupied is (6 choose 4)(1/64) = 15/64
The probability of five buffers being occupied is (6 choose 5)(1/64) = 6/64
So the probability of event A is (15/64) + (20/64) + (15/64) + (6/64) = 56/64.
B = At least three but no more than five buffers occupied.
To find the probability of event B, we need to find the number of outcomes where at least three but no more than five buffers are occupied.
This can be done by summing the probabilities of each individual outcome where three, four, or five buffers are occupied and subtracting the probability where six buffers are occupied.
The probability of three buffers being occupied is (6 choose 3)(1/64) = 20/64
The probability of four buffers being occupied is (6 choose 4)(1/64) = 15/64
The probability of five buffers being occupied is (6 choose 5)*(1/64) = 6/64
So the probability of event B is (20/64) + (15/64

Answer:
y- intercept = - 26
Step-by-step explanation:
to find the y- intercept, obtain the equation of the line in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (34, - 52) and (x₂, y₂ ) = (68, - 78) ← 2 ordered pairs from the table
m = [tex]\frac{-78-(-52)}{68-34}[/tex] = [tex]\frac{-78+52}{34}[/tex] = [tex]\frac{-26}{34}[/tex] = - [tex]\frac{13}{17}[/tex] , then
y = - [tex]\frac{13}{17}[/tex] x + c
to find c substitute any of the ordered pairs into the equation and solve for c
using (51, - 65 ) , then
- 65 = - [tex]\frac{13}{17}[/tex] (51) + c = - 39 + c ( add 39 to both sides )

Slope = 4/3
Step-by-step explanation:
The coordinates are,
→ x1 = 6, y1 = 0
→ x2 = 0, y2 = -8
Formula we use,
→ Slope(m) = (y2 - y1)/(x2 - x1)
Now required slope will be,
→ m = (y2 - y1)/(x2 - x1)
→ m = (-8 - 0)/(0 - 6)
→ m = (-8)/(-6)
→ m = 8/6
→ [ m = 4/3 ]
Hence, the slope is 4/3.

The inclusive range includes all numbers from 2 to 89, while the exclusive range includes all numbers from 3 to 88, excluding the two endpoints.
Inclusive Range: Low Score (2) = Low Score (7) + 1 = 7 + 1 = 8
High Score (89) = High Score (45) + 44 = 45 + 44 = 89
Exclusive Range: Low Score (3) = Low Score (7) + 1 = 7 + 1 = 8
High Score (88) = High Score (45) + 44 = 45 + 44 = 89
The inclusive range includes all values within a given set of numbers, including the endpoints. In this case, the low score is 7 and the high score is 45. Adding 1 to the low score gives us a low score of 8, and adding 44 to the high score gives us a high score of 89. This gives us an inclusive range of 8 to 89.
The exclusive range excludes the endpoints, so we add 1 to the low score and subtract 1 from the high score. This gives us a low score of 8 and a high score of 88, giving us an exclusive range of 8 to 88. This means that the range excludes the values of 7 and 89 from the set.

Suppose you have 6 homework assignments to complete one night.
In how many different orders can you complete all of the assignments
There are a total of 6 homework assignments that need to be completed one night. The number of ways to arrange n items in a specific order is n! (n factorial).
How many different orders can you complete all of the assignments?Therefore, for 6 homework assignments, the number of different orders in which they can be completed is 6! = 720.
This means that there are 720 different ways in which you can complete these 6 assignments on one night. Each permutation represents a unique order in which the assignments can be completed, such as starting with assignment 1, then 2, then 3, and so on, or starting with assignment 4, then 5, then 6, and then 1, and so on.
It is worth noting that this formula is only applicable when the order of the assignments matters. If the order of the assignments does not matter, then we would use the formula for combinations, which is n! / (r!(n-r)!).
Multiplying all of these options together results in 6 x 5 x 4 x 3 x 2 x 1 = 720 possible ways to complete the assignments in a different order. This is known as the permutation formula, which states that the number of ways to arrange n items in a specific order is n! (n factorial).
