Roster form : {8,12,16}
The Roster form of { 8,12,16 } is {X;X=4k ,k ∈ (2,34)}
Roster form:
A set's roster notation is a straightforward mathematical representation of the set. The elements (or members) of a set are listed in a row inside the curly brackets in the roster form. If the set contains more than one element, each pair of elements is separated by a comma symbol. Because the enumeration is done one by one, the roster form is also known as the enumeration notation.
Given a set in a set builder form i.e.{ 8,12,16 } and asked to convert into Roster form
Roster form of { 8,12,16 } ={X;X=4k, k ∈ (2,34)}

Step-by-step explanation:
Plug in both point values into each of the equations and see if the LHS = RHS.
Only eq A satisfies for both points
eq B satisfies for point (5,6) but not for (1,1)
Equations C and D satisfy for neither point
The equation of the straight line passing through the points (1, 1) and (5, 6) is 4y = 5x - 1.
What is the general equation of straight line?The general equation of a straight line is -
y = mx + c
Here {m} is the slope which also denotes the unit rate. Unit rate is the rate at which the value of {y} changes per unit change in the value of {x}.
Given is the table as shown in the figure.
The line passes through the points (1, 1) and (5, 6). We can write the slope of the line as -
m = (6 - 1)/(5 - 1)
m = 5/4
So, we can write the equation as -
y = 5x/4 + c
For the point (1, 1), we can write -
1 = 5/4 + c
c = 1 - 5/4
c = (4 - 5)/4
c = -1/4
So, the equation will be -
y = 5x/4 - 1/4
y = (5x - 1)/4
4y = 5x - 1
Therefore, the equation of the straight line passing through the points (1, 1) and (5, 6) is 4y = 5x - 1.

the median of 4 numbers is 48
3 of the numbers are:
42, 51, and 52
what is the other number
When 3 among four numbers are 42,52,52 and their median is 48 then the fourth number is 45.
What is Median?
Median is the middle number when the given numbers are arranged in ascending or descending order, basically it divides the data into two halves the one is higher half another is lower half of the data.
For even numbers of data we find median by first arranging the data in ascending order then we take average of the two middle terms.
Given that among 4 numbers three are 42,51,52
Assume that the fourth no be x and also Assume that it is among the middle two numbers as median is given 48 to find this number?

A sample of 40 CDs from a student's collection showed a mean length of 52.74 minutes with a standard deviation of 13.21 minutes. Construct a 95% confidence interval for the population standard deviation. (Round your answers to 4 decimal places.) The 95% confidence interval is from to .
Answer:
(48.65, 56.83)
Step-by-step explanation:
Given that :
Sample size (n) = 40
Mean (m) = 52.74
Standard deviation (s) = 13.21
α = 95%
Confidence interval around sample mean can be obtained using the relation :
Mean ± Zstatistic * s/√n
Z score for 95% confidence interval = 1.96 (Z probability calculator)
s / √n = 13.21 / √40 = 2.0886843
Lower limit of confidence interval :
52.74 - (1.96 * 2.0886843) = 48.646178772 = 48.65
Upper limit of confidence interval :
52.74 + (1.96 * 2.0886843) = 56.833821228 = 56.83

Double everything in the second equation to get 4x-2y+4z=6
Add this result to the first equation
[tex]x+2y-4z = 4\\4x-2y+4z = 6\\5x+0y+0z = 10[/tex]
The first two lines of that expression above shows us adding x+2y-4z=4 to the equation 4x-2y+4z = 6
The x terms add to x+4x = 5x
The y terms add to 2y+(-2y) = 0y
The z terms add to -4z+4z = 0z
The terms on the right hand side add to 4+6 = 10
That's how we end up with the new equation 5x+0y+0z = 10
That becomes 5x = 10 which solves to x = 2 when we divide both sides by 5.
------------------------
Use this x value in the third original equation to find z
3x-8z = -2
3(2)-8z = -2
6-8z = -2
-8z = -2-6
-8z = -8
z = -8/(-8)
z = 1
------------------------
Use the x and z values we found to find y
x+2y-4z = 4
2+2y-4(1) = 4
2+2y-4 = 4
2y-2 = 4
2y = 4+2
2y = 6
y = 6/2
y = 3
----------------------
Overall we get the solutions to be x = 2, y = 3 and z = 1
We can say the solution as an ordered triple is (x,y,z) = (2,3,1)

A discount store buys a shipment of playground slides at a cost of $290 each. The playground
slides will be sold for $783 apiece. What is the mark-up, as a percentage?
Write your answer using a percent sign (%).
The mark-up for the playground slides is 170%. The mark-up refers to the price added to the cost to find out the selling price of a product.
Mark-up is the difference between the selling price and cost price of a product.It is usually represented as a percentage, the mark-up percentage is calculated over the cost of the product. In other words we can say that mark-up is the profit gained from selling a particular product. Here it is said that the cost of a playground slide is $290 and the selling price of the playground slide is $783. We need to find the mark-up percentage of the playground slide.
Mark-up %=[tex]\frac{selling price-cost}{cost}[/tex]×100=[tex]\frac{783-290}{290}[/tex]x100=[tex]\frac{493}{290}[/tex]x100=170%
Therefore the mark-up percentage of the playground slide is 170%.

Rewrite 14 1/3 as an improper fraction
Answer:
Step-by-step explanation:
((14×3) + 1 )/3 = (43/3)
14 1/3 can be expressed as 43/3, which is an improper fraction.
To rewrite 14 1/3 as an improper fraction, we need to convert the mixed number into a fraction.
First, we multiply the whole number (14) by the denominator of the fraction (3) and add the numerator (1). This gives us the numerator of the improper fraction. The denominator remains the same.
14 × 3 = 42
Next, we add the numerator (1) to the result we obtained above.
42 + 1 = 43
Therefore, the improper fraction equivalent to 14 1/3 is 43/3.
In the fraction 43/3, the numerator (43) represents the total number of parts we have, and the denominator (3) represents the size of each part. It indicates that we have 43 equal parts of size 1/3.
