A box contains 3 coins. One coin has 2 heads and the other two are fair. A coin is chosen at random from the box and flipped. If
Blababa [14]

Answer: Our required probability is \dfrac{1}{2}

Step-by-step explanation:

Since we have given that

Number of coins = 3

Number of coin has 2 heads = 1

Number of fair coins = 2

Probability of getting one of the coin among 3 = \dfrac{1}{3}

So, Probability of getting head from fair coin = \dfrac{1}{2}

Probability of getting head from baised coin = 1

Using "Bayes theorem" we will find the probability that it is the two headed coin is given by

\dfrac{\dfrac{1}{3}\times 1}{\dfrac{1}{3}\times \dfrac{1}{2}+\dfrac{1}{3}\times \dfrac{1}{2}+\dfrac{1}{3}\times 1}\\\\=\dfrac{\dfrac{1}{3}}{\dfrac{1}{6}+\dfrac{1}{6}+\dfrac{1}{3}}\\\\=\dfrac{\dfrac{1}{3}}{\dfrac{2}{3}}\\\\=\dfrac{1}{2}

Hence, our required probability is \dfrac{1}{2}

No, the answer is not \dfrac{1}{3}

The sets of numbers 7,24,25 and 9,40,41 are Pythagorean triples. Use what you know about the Pythagorean Theorem and explain or
ololo11 [35]

Answer:

Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

7-24-25

7² + 24² = 25²

49 + 576 = 625

625 = 625

9-40-41

9² + 40² = 41²

81 + 1600 = 1681

1681 = 1681

What is the area of a semi circle that has a diameter of 1 1/2?
SVEN [57.7K]

Answer:

A=0.8836

Step-by-step explanation:

Area of circle:

\pi r^2

By using the area of a circle, we can get the area of a semicircle:

\frac{\pi r^2}{2}

Let's convert the mixed fraction to an improper fraction and then a decimal:

1\frac{1}{2} = \frac{3}{2} = 1.5

Now, we solved for the diameter, to get the radius, we need to divide the diameter by 2:

\frac{1.5}{2} =0.75

Now we have the radius, so we can plug in our values and find the area:

\frac{\pi0.75^2}{2} = 0.88357293

A=0.88357293

The distance in the x-coordinates from A(–2, 2) to the center of dilation F(1, 1) is unit(s).
lilavasa [31]

Answer:

The distance in the x-coordinates from A(–2, 2) to the center of dilation F(1, 1) is 3 unit(s)

Step-by-step explanation:

Give points:

A(-2,2)

Center of dilation F(1,1)

The distance in the x-coordinates fro A to F can be given by =\ |x_2-x_1\ |=\ |1-(-2)\ |=\ |1+2\ | = 3\ units.
