A spinner is divided into two equal parts, one red and one blue. The set of possible outcomes when the spinner is spun twice is S = {RR, RB, BR, BB}. Let X represent the number of times blue occurs. Which of the following is the probability distribution, PX(x)? A 2-column table has 3 rows. The first column is labeled x with entries 0, 1, 2. The second column is labeled P x (x) with entries 0. 25, 0. 5, 0. 25. A 2-column table has 3 rows. The first column is labeled x with entries 0, 1, 2. The second column is labeled P x (x) with entries 0. 33, 0. 33, 0. 33. A 2-column table has 3 rows. The first column is labeled x with entries 0, 1, 2. The second column is labeled P x (x) with entries 0. 5, 0. 5, 0. A 2-column table has 3 rows. The first column is labeled x with entries 0, 1, 2. The second column is labeled P x (x) with entries 0, 0. 5, 0. 5.
A 2-column table that has 3 rows. The first column is labeled x with entries 0, 1, 2. The second column is labeled P x (x) with entries 0. 25, 0. 5, 0. 25.
What is Probability?The probability helps us to know the chances of an event occurring.
[tex]\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
We know about the probability, therefore, let's find the probability of each of the cases.
When the number of success of the spinner landing on blue is none, therefore, the spinner does not land on the blue color at all.
[tex]\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
Now, as it is given that there is only one case when the spinner does not land on the blue side(RR) in the set, S = {RR, RB, BR, BB}. therefore,
[tex]\rm{Probability(X=0)=\dfrac{1}{4} = 0.25[/tex]
When the number of success of the spinner landing on blue is just once, therefore, the spinner does land on the blue color only once out of the two spin.
[tex]\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
Now, as it is given that there are two cases when the spinner does land on the blue side(RB, BR) in the set, S = {RR, RB, BR, BB}. therefore,
[tex]\rm{Probability(X=1)=\dfrac{2}{4} = 0.25[/tex]
When the number of success of the spinner landing on blue is twice, therefore, the spinner does land on the blue color both the times the spinner is spun.
[tex]\rm{Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
Now, as it is given that there is only one case when the spinner does land on the blue side twice(BB) in the set, S = {RR, RB, BR, BB}. therefore,
[tex]\rm{Probability=\dfrac{1}{4} = 0.25[/tex]
Now, if we draw the table of the data and the probability we will get the following table,
x P(X)
0 0.25
1 0.50
2 0.25
Hence, the table that is correct is table A, which is A 2-column table that has 3 rows. The first column is labeled x with entries 0, 1, 2. The second column is labeled P x (x) with entries 0. 25, 0. 5, 0. 25.

D. 26
Answer:
A. 8
Step-by-step explanation:
The angle shown is a 90 degree right angle (shown by the box where the vertex is)
We see that the first angle inside the right angle is 50 degrees, so the other angle must be 40 because the degrees must add up. We can set up an equation here.

5. The corners of triangle PQR lie on a circle. PQ = 3i + 4j and PR = -8i + 6j. By showing that the triangle is right-angled, or otherwise, find the area of the circle. [8]
The formed triangle is not right angled triangle. The area of circle is 19.64 square units.
What is the general equation of a Straight line? State the area of circle? How do we express vectors.The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The area of circle is -
A = πr² = π(d/2)²
A vector is represented by -
A = A[x] i + A[y] j + A[z] k
We have the following problem -
The corners of triangle PQR lie on a circle. PQ = 3i + 4j and PR = -8i + 6j.
|PQ| = 5 units
|PR| = 10
PR + RQ = PQ
RQ = PQ - PR
RQ = 11i - 2j
|RQ| = 11.18
It can be seen that it is not a right angled triangle.
Equation of the diameter of the circle -
y = 4/3x {Assuming it pass through origin}
Diameter length = 5
Radius length = 5/2
Area of circle = 22/7 x 5/2 x 5/2 = 19.64 square units.
Therefore, the formed triangle is not right angled triangle. The area of circle is 19.64 square units.

Answer:
x = 55° (nearest degree)
Step-by-step explanation:
Trig ratios:
[tex]sin(\theta)=\dfrac{O}{H} \ \ \ cos(\theta)=\dfrac{A}{H} \ \ \ tan(\theta)=\dfrac{O}{A} \ \ \[/tex]
where [tex]\theta[/tex] is the angle, O is the side opposite the angle, A is the side adjacent to the angle, and H is the hypotenuse of a right triangle
Given:
[tex]\theta=x[/tex]A = 3.3H = 5.7[tex]\implies cos(x)=\dfrac{3.3}{5.7}[/tex]
[tex]\implies x=\arccos \dfrac{3.3}{5.7}=54.623459...[/tex]
⇒ x = 55° (nearest degree)
Answer:
54.6° OR 55° rounded up.
Step-by-step explanation:
So it is a fact that 3.3 is adjacent to x. And 5.7 is the hypotenuse.
Now, let's think of SOHCAHTOA: *Always remember that*
SOH: Sin = Opp/Hyp
CAH: Cos = Adj/Hyp
TOA: Tan = Opp/Adj
We will be using CAH since we have the adjacent and the hypotenuse.
Now, you need to plug in the numbers to the correct placement, in this case, it will look like this:
Cos(x) = 3.3/5.7
*If I were you, I'd use a Cosine calculator online or just your handy-dandy standard calculator because you can't just plug in 3.3/5.7 like that and expect to get the answer.*
*In order to find the cosine on a regular calculator, you must press the inverse button, followed by the cos button. Or just use the "arccos" button if it's on there*

What is permutation?A permutation is a mathematical technique that determines the number of possible arrangements in a set when the order of the arrangements matters.
Permutation Formula[tex]nP_{r} =\frac{n!}{(n-r)!}[/tex]
Where,
P is the number of arrangements.
r is the of objects selected.
n is the total numbers of object.
According to the question.
We have a word "COUNT".
Total number of letters in word "COUNT" is 5.
⇒ Total number of objects, n = 5
Since, we have to form different words by using 5 letters of count.
⇒ Total number of objects we have to select, r = 5
Therefore, the total number of ways to arrange the letters of "COUNT" is given by
[tex]5P_{5}=\frac{5!}{(5-5)!}[/tex]
⇒[tex]5P_{5} =\frac{5!}{0!}[/tex]
⇒[tex]5P_{5} =\frac{5!}{1}[/tex] (because,0! = 1)
