Find the cardinal number of set A = { a, b, c, d, e, f}
if answered correctly and answer is explained I will give brainliest!!!!
Answer:
What is the cardinal number of a set?
The number of distinct elements in a finite set is called its cardinal number. It is denoted as n(A) and read as ‘the number of elements of the set’.
For example:
(i) Set A = {2, 4, 5, 9, 15} has 5 elements.
Therefore, the cardinal number of set A = 5. So, it is denoted as n(A) = 5.
(ii) Set B = {w, x, y, z} has 4 elements.
Therefore, the cardinal number of set B = 4. So, it is denoted as n(B) = 4.
(iii) Set C = {Florida, New York, California} has 3 elements.
Therefore, the cardinal number of set C = 3. So, it is denoted as n(C) = 3.(iv) Set D = {3, 3, 5, 6, 7, 7, 9} has 5 element.
Therefore, the cardinal number of set D = 5. So, it is denoted as n(D) = 5.
(v) Set E = { } has no element.
Therefore, the cardinal number of set D = 0. So, it is denoted as n(D) = 0
Step-by-step explanation:
Using the cardinality concept, it is found that the cardinal number of the set is of 6.
------------------------------------------------------
The cardinality of a set is given by the number of unique elements in the set.For example: set {a,a,a} has cardinality 1, as there is only one unique element, which is a.set {a,b,c} has cardinality 3, as there are three unique elements, which are a,b and c.set {a,a,b} has cardinality 2, as there are two unique elements, which are a and b.------------------------------------------------------
set {a,b,c,d,e,f} has cardinality 6, as there are 6 unique elements, which are: a, b, c, d, e and f. Thus, the cardinal number of the set is of 6.https://brainly.com/question/23976339

Answer:
I need the values of either X or Y to solve this. I can solve for what X is though.
Step-by-step explanation:
A: X = -12
B: X =78
C: X = 12.13

In a grocery store, a $12 case of 24 soda is labeled, "Get a 20% discount." If you pay a 9.15% tax on the final price, how much will you pay per soda?
(please tell me how you did it)
Answer:
Soooo....
$0.44
Step-by-step explanation:
24 soda in one case and $12 for one case
20% off 12$ = 9.60
9.60 + 9.15% tax = 10.48
10.48 divided by 24
would could be about $0.44 each

What is the value of y if x is 8 in the linear equation graphed?
A) 4
B) 5
C) 7
D) 13
Answer:
When x = 8, our y-value is equal to 13.
Step-by-step explanation:
We are given a graph that shows a linear relationship between our variables x and y.
In math, the slope-intercept form of an equation is written as:
[tex]\bullet \ y=mx+b, \text{where m is our slope and b is our y-intercept.}[/tex]
We also can note that there is another way to state a function: [tex]f(x)[/tex]. This replaces the y in the slope-intercept form and they can be used interchangeably.
[tex]\bullet \ f(x) = mx + b[/tex]
So, when we look at our graph, we can see that we have x-values on the bottom horizontal axis and y-values on the left vertical axis.
When we check this, we see that our x-values range from 0 to 9 and our y-values range from -2 to 14.
Therefore, we can see that since x is supposed to be equal to 8, we are going to draw a vertical line from x = 8 and see what point this intersects.
We see that the line would intersect the rightmost point and it is located between y = 12 and y = 14.
Therefore, we can just take the median of these two values and find our y value.
[tex]\displaystyle 12 + 14 = 26\\\\\frac{26}{2} = 13[/tex]
Therefore, y is equal to 13 and our answer is Choice D.

18 ÷ x = -2
x = _____
Answer:
-9
Step-by-step explanation:
18÷x = -2
18 = -2×x
18 = -2x
-9 = x
x = -9
Answer:
-9
Step by step explanation:
it can also be written as; 18 over x is equal to -2 over 1
you cross multiply to get 18 = -2x
then multiply through with -2; 18 over -2 = -2x over -2
you cross out; -2 cancels itself and -2 goes into 18 , -9 times
Therefore; the answer is -9

A ladder is placed against a wall. The foot of ladder is 3 feet away from the wall and the top of the latter hits the wall 15 feet of the ground. What is the slope of the ladder?
RIGHT ANSWERS ONLY!
Answer:
5
Step-by-step explanation:
The slope of the ladder is 5.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
Given that, the foot of ladder is 3 feet away from the wall and the top of the ladder hits the wall 15 feet of the ground.
We know that, slope = Rise/Run
Now, slope =15/3
= 5
Therefore, the slope of the ladder is 5.
