Probability is the chance or likelihood of a thing to happen. It is the extent to which an event is likely to occur. It is seen that how many times a thing occur out of the total one.

In this example, there are 5 vowels in MATHEMATICAL, these are, A, E A, I, A.

There are total 12 letters in this word. So the probability is 5/12. So there is 5/12 chances of vowels to occur whenever a piece of paper is taken out of the bag.

(5) Rhea ran 6 laps on a track. Each lap is 200 yards. Rhea's average speed for
sashaice [31]

Answer:

72 yd / min

Step-by-step explanation:

The first thing is to fully calculate the distance traveled, each lap is 200 yards and how 6 laps would be:

200 * 6 = 1200

Now, let's divide the race into how the statement tells us:

1200 * 2/3 = 800

1200 * 1/3 = 400

That is, in the first 800 yards it goes to 80 yd / min and then in the remaining 400 yards it goes to 60 yd / min, let's calculate the time Rhea lasted:

800/80 = 10 min

400/60 = 6,667 min

Which means that in total it would be:

10 + 6,667 = 16,667

In other words, Rhea took 16,667 minutes to travel 1,200 yards, so the speed would be:

1200 / 16,667 = 72

Therefore the average Rhea speed was 72 yd / min

If AD and BD are bisectors of CAB and CBA respectively. Find the sum of angles x and y.
olchik [2.2K]
The picture in the attached figure

step 1
we know that
It is given that AD and BD are bisectors of ∠CAB and ∠CBA respectively.
Therefore,
x = ∠CAB/2 -----> equation 1
y = ∠CBA/2 -----> equation 2

step 2
In triangle ABC,
∠CAB + ∠CBA + ∠ACB = 180° ----> [The sum of all three angles of a triangle is 180°]
∠CAB + ∠CBA + 110° = 180°
∠CAB + ∠CBA = 180° - 110°
∠CAB + ∠CBA = 70° ------> divide by 2 both sides
∠CAB/2 + ∠CBA/2 = 70/2 -------> equation 3
substitute equation 1 and equation 2 in equation 3
x+y=35

hence

the answer is
x+y =35°
⇒ x + y = 35° ...[From equation (1) and (2)]

Find the solution to the inaquality<br> N+35&lt;22
NikAS [45]

Step-by-step explanation:

N + 35 < 22

To find a solution to this inequality, we need to get N to one side of the equation by itself. Since we have N + 35 on the left-hand side of the equation, we can get

N + 35 < 22

N + 35 - 35 < 22 - 35

N < -13

The series will be:

4+16+64+.......+2^{50}

Hence, Option A is the right answer

Step-by-step explanation:

The series can be fount out by putting the values of i in the expression written with the summation

The expression is:

2^{2i}

while i = 1 to 25

Putting i = 1

2^{2(1)}\\= 2^2\\= 4

Putting i = 2

2^{2(2)}\\= 2^4\\= 16

Putting i = 3

2^{2(3)}\\= 2^6\\= 64

....

Putting i = 25

2^{2(25)}\\= 2^{50}

The series will be:

4+16+64+.......+2^{50}

Hence, Option A is the right answer
