Emily has a coin with P(H) = pi and Pete has a coin with P(H) = P2. Emily tosses her coin n times, and denote the number of head

s by X. Now Pete tosses his coin X times. What should be the distribution of the number of heads that Pete gets? Try to answer this question from two different approaches.
(a) Answer this question by constructing suitable binomial experiments.
(b) Answer this question by direct calculation. This is a challenging task. Hint: Try to use the binomial expansion xkym-k = (x + y)", k k=o. which holds for ALL positive integers m and real numbers x, y.

What is the perimeter of a square which has the same area as a circle with circumference of 4π?
enot [183]

Answer:

perimeter = 8\sqrt{\pi }

Step-by-step explanation:

We require to calculate the area (A) of the circle

A = πr² ← r is the radius

circumference = 4π = 2πr, hence

2πr = 4π ( divide both sides by 2π )

r = 2, hence

A = π × 4 = 4π

The area of the square is therefore 4π and area = s² ← s is the side length

s² = 4π ( take the square root of both sides )

s = \sqrt{4\pi } = 2\sqrt{\pi }, hence

perimeter = 4 × 2\sqrt{\pi } = 8\sqrt{\pi }

The sum of the ages of Jeremy and Kimberly is 64 years. 8 years ago, Jeremy's age was 2 times Kimberly's age. How old is Jeremy
TiliK225 [7]

Answer:

36.666 (The six keeps going)

Step-by-step explanation:

In this question you'll be trying to find out what x is.

(x-8), this is from the amount of years ago and 2(56-x) is from subtracting 8 with 64 and the 2 came from the fact that Jeremy is twice the age.

(x-8)=2(56-x)

x-8=102-2x

Now we want to have x by itself  so we'll add 2x on both sides to remove the -2x from the right side.

3x-8=102 (Add up on both sides)

3x=110 (Divide by 3)

x=36.666

koban [17]

Answer:

6

Step-by-step explanation:

3(1)=3       3(2)=6          3(3)=9      3(4)=12     3(5)=15

3(6)=18     3(7)=21         3(8)=24

----------------------------------------------------

3(6)=18 is closest to 20

so the greatest number of batches Xiaoming can make is 6.
