Consider the set t = {1, 2, 3, 4, 5, 6}. let r = {(a, b) | a divides b} be a relation on the set t. the tabular representation for the ordered pairs of the given relation r on the set t is:_________
The ordered pairs of the given relation r on the set t is ungrouped data.
What is ungrouped data?The data you initially collect from an experiment or study is known as ungrouped data. The data is unsorted, unclassified, or otherwise grouped; it is therefore considered to be raw. A list of numbers is an ungrouped piece of data.
Ungrouped data is a distribution type where each piece of information is presented in its rawest form. For instance, a batsman's five most recent scores are 45, 34, 2, 77, and 80.

Find the geometric mean between pair of numbers.
3√5/4 and 5√5/4
The geometric mean of 3√5/4 and 5√5/4 is 5√3/4.
Geometric mean, like arithmetic mean, is a kind of average and a measure of central tendency.
To solve for the geometric mean, we multiply the numbers together and then take a square root (for two numbers), cube root (for three numbers) etc. In other words, geometric mean is the nth root of the product of n values.
The formula for the geometric mean is given by:
GM = n√x1 x2 . . . xn
Solving for the geometric mean between 3√5/4 and 5√5/4 using the formula:
GM = n√x1 x2 . . . xn
where n = 2, x1 = 3√5/4, and x2 = 5√5/4
GM = √(3√5/4)(5√5/4)
GM = √(75/16)
GM = 5√3/4
Hence, the geometric mean of 3√5/4 and 5√5/4 is 5√3/4.

Using it's concept, the average rate of change of the function in the intervals is given by:
a. 1.
b. -5/3.
c. -1.
d. 4.
e. -3.
f. 0.
What is the average rate of change of a function?
The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:
[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]
For item a, we have that:
f(-3) = 0.f(-2) = 1.Hence the rate is:
r = (1 - 0)/(-2 - (-3)) = 1.
For item b, we have that:
f(-2) = 1.f(1) = -4.Hence the rate is:
r = (-4 - 1)/(1 - (-2)) = -5/3.
For item c, we have that:
f(0) = -3.f(1) = -4.Hence the rate is:
r = (-4 - (-3))/(1 - 0) = -1.
For item d, we have that:
f(1) = -4.f(2) = 0Hence the rate is:
r = (-0 - (-4))/(2 - 1) = 4.
For item e, we have that:
f(-1) = 0.f(0) = -3.Hence the rate is:
r = (-3 - 0)/(0 - (-1)) = -3.
For item f, we have that:
f(-1) = 0.f(2) = 0.Hence the rate is:
r = (0 - 0)/(2 - (-1)) = 0.

What is inequality ?
In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size.
Plan 1: $23 per month for unlimited calls
Plan 2: $19 per month + $0.04 per call
Let the number of calls be x
a. 19 +0.04x >23
0.04x >4
x > 100
b. If Plan 1 should be more economical, then the above inequality represents that cost of plan 2 should be more than plan 1. therefore, the plan 2 is greater than plan 1.

Consider the inequality 38 ≤ bx + 8
What value of b will result in the solution x ≤ - 6?
For the value of (b = -5) the result of the solution is x ≤ - 6.
What is termed as the inequality?The term inequality refers to a mathematical equation wherein the sides are not equal. An inequality equates any two values and shows that one is less, greater, or equal to the value on either side of the equation.
Rule 1: When inequalities are connected, they can be crossed. As a result, if an is greater than b and b is greater than c, a will be greater than c as well.Rule 2: When you swap the values, the sign as well reverses.Rule 3: An inequality can be either > or, but not both at the same time.Rule 4: Reversing the sign by multiplying both sides of the inequality by the a negative sign.Consider the given expression;
38 ≤ bx + 8
Simplify the equation;
38 - 8 ≤ bx
30 ≤ bx
Multiply both side with negative sign; by the rule four, the sign of inequality will also change.
- 30 ≥ -bx
or -bx ≤ - 30
For converting the value to the expression x ≤ - 6; the value which should be divide the 30 is 5.
Thus,
-(-5)x ≤ - 30
Thus, the value of b is found as (b = -5).

Determine whether each set of numbers can be the measure of the sides of a triangle. If so, classify the triangle as acute, right, or obtuse. Justify your answer.
a. 11,60,61
The following set of numbers, 11, 60, and 61, can be the measures of the sides of a right triangle.
A triangle is a polygon with three sides and three vertices.
To know if a set of number is a valid measure of the sides of a triangle, it must follow the Triangle Inequality Theorem which states that the sum of any two sides must be greater than the third side, such that a + b > c, a + c > b, and b + c > a.
let a = 11, b = 60, and c = 61
a + b > c 11 + 60 > 61 71 > 61 True
a + c > b 11 + 61 > 60 72 > 60 True
b + c > a 60 + 61 > 11 121 > 11 True
To know what type of triangle based on the length of its side:
1. Take the sum of the squares of the two smaller sides.
11^2 + 60^2 = 3721
2. Compare it to the square of the largest side.
61^2 = 3721
3721 = 3721
If the sum of the squares of the 2 is larger than the square of the 3rd, it is an acute triangle.
if they are equal, it is a right triangle.
if they are smaller, then it is an obtuse triangle.
Hence, 11, 60, and 61 can be the measure of the sides of a right triangle.

A bag of jelly beans contains 7 red, 11 yellow, and 13 green. Victoro picks two jelly beans from the bag without looking. What is the probability as a percent rounded to the nearest tenth that Victoro picks a green one and then a red one?
The probability, expressed as a percentage rounded to a nearest tenth, that Victoro chooses a green jelly then a red one is 0.1.
What is defined as the combinations in a probability?A combination is a preference of all or part of a group of objects, regardless of their order of selection.
You can choose the items in just about any order in combinations. Permutations and combinations are often confused.
Now, as per the given question;
The total number of red jelly beans in a bag is 7.
The total number of yellow jelly beans in a bag is 11.
The total number of green jelly beans in a bag is 13.
Thus, the total number of jelly beans in a bag is;
7 + 11 + 13 = 31.
First, Victoro picks the green one;
Thus, the probability of picking a green jelly out of total 13 green jellys is;
¹³C₁/ ³¹C₁ = 13/31
Now, as the second jelly picked by Victoro is red which is without replacement.
Thus, the probability for getting a red jelly out of total 30 left jellys is;
⁷C₁/ ³⁰C₁ = 7/30
Therefore, the total probability that Victoro picks a green one and then a red one is ;
= 13/31×7/30
= 91/930
= 0.097
= 0.10 (rounded to the nearest tenth)
Therefore, the probability of getting the red jelly after the green jelly is 0.10.

The sum of the given arithmetic series 5+6+7+ . . . . . . +11 is 56.
Suppose we are given an arithmetic series:
a(1) + a(2) + a(3) + a(4) + .... + a(n)
Then, each term of the series follow the general formula:
a(n) = a(1) + (n-1) . d
Where:
a(n) = nth term
a(1) = first term
d = common difference = a(n) - a(n-1)
We are given:
5+6+7+ . . . . . . +11
Parameters we get from this series:
a(1) = 5
d = 6 - 5 = 1
a(n) = 11
We need to find n that results in a(n) = 11
Substitute a(n) = 11, a(1) = 5, and d = 1:
a(n) = a(1) + (n-1) . d
11 = 5 + (n-1) . 1
11 = n + 4
n = 7
The sum of the first n terms of an arithmetic series is:

Write the standard form of the equation of the circle that passes through the given point and whose center is at the origin.
(-6,0)
The equation of the circle that passes through the point (-6 , 0) and has a center located at the origin is x^2 + y^2 = 36.
Using the distance formula, get the radius of the circle by solving for the distance between the center and the point (-6 , 0).
radius = distance = √(x2 - x1)^2 + (y2 - y1)^2
radius = √(-6 - 0)^2 + (0 - 0)^2
radius= √36
radius = 6
The standard form of the equation of the circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.
Given the radius and center of the circle, substitute these values to the standard form of the equation of the circle.
(x - h)^2 + (y - k)^2 = r^2
