The diameter is 48 feet. The radius is half of the diameter, so it is 24 feet. The area can be found using the formula pi r ^ 2. So, the area is 576 pi

suppose you toss 3 coins at one time. what is the probability that exactly two land with heads facing up?
mezya [45]

The probability of getting heads is 3/8.

<u>Probability:</u>

Probability is a branch of mathematics that quantifies the likelihood of an event occurring or the likelihood of a statement being true. Probability is a number between 0 and 1, with 0 generally indicating impossibility and 1 indicating certainty. that an event will occur. A simple example is tossing a fair (unbiased) coin. Since the coin is fair, the two outcomes (heads and tails) are equally likely. The probability of heads is the same as the probability of tails. Since no other outcome is possible, the probability of heads or tails is 1/2 (also written as 0.5 or 50%).

Since 3 is a small number, let's list out all possible combinations.

H represents a head while T represents a tail.

3 Heads

HHH

2 Heads

HHT

HTH

THH

1 Head

HTT

THT

TTH

0 Head

TTT

The answer is

3/1+3+3+1=3/8

                                            OR

In general, we will find that the list resembles a particular row of the pascal's triangle.

If you want to know the probability of getting r heads (or tails) from n flips, it is the sum of the rth  elements in the n + 1 line. All elements of the series n+1.

\left[\begin{array}{ccc}N\\\\R\end{array}\right]/ 2ⁿ = \frac{n!}{r! * (n - r)!* 2^{n} }

n this case,

N =3andR= 2

   3!/ 2!×1! × 2³

= 6/ 2× 1 × 8

= 3/8

If csc 0=8÷7 which equation represents cot 0
Dahasolnce [82]

Answer: Cot\theta =\frac{\sqrt{15} }{7}

Step-by-step explanation:

Since, given cosec\theta=\frac{8 }{7}

And we know that Cot\theta=\sqrt{cosec^2\theta-1}

Therefore, Cot\theta=\sqrt{cosec^2\theta-1} = \sqrt{(8/7)^2-1}= \sqrt{64/49-1}

⇒Cot\theta=\sqrt{64-49/49}=\sqrt{15/49}=\sqrt{15}/7

Thus,  Cot\theta =\frac{\sqrt{15} }{7}

What you have to do to find the median of the data is first put that data into order numerically. You can go largest to smallest or smallest to largest, it doesn't matter.   <span>

22, 24, 28, 28, 30, 31, 31, 32, 32, 35, 36, 37, 38, 41, 42, 42, 44, 44, 45, 46, 46, 47, 47, 49, 50

Once you put them into order, you count towards the middle. You have 25 data points, so the middle, which will be your median number, will be 13 points in. 

The median is 38</span>
