A fair coin and a biased coin where the probability of obtaining a head is twice the probability of obtaining a tail. if both ar

Art [367]

Answer:

See below in bold.

Step-by-step explanation:

For the fair coin Prob(head) = 1/2 and Prob(Tail) = 1/2.

For the biased coin it is Prob(head) = 2/3 and Prob(Tail) = 1/3.

a) Prob(2 heads) = 1/2 * 2/3 = 1/3.

b) Prob(2 tails) = 1/2 * 1/3 = 1/6.

c) Prob(1 head ) = Prob(H T or T H) = 1/2 * 1/3 + 1/2 * 2/3) = 1/6+1/3 = 1/2.

d) Prob (at least one head) = prob (HH or TH or HT) = 1/3 + 1/2 = 5/6.

The volume of a cube is 27000 cubic inches. What is the length of one side?

anyanavicka [17]

Given:

Volume of a cube = 27,000 in^3

(Note: A cube has equal sides)

The volume of a cube = a^3

So,

$\begin{gathered} 27000=a^3 \\ \sqrt[3]{27000}\text{ = a} \\ a\text{ = 30 in.} \end{gathered}$

Therefore, the lenght of one side is 30 inches.

Manny Brought a brand new car in 2012 for $28750. if the car depreciates by 12% each year, write n exponential function to model

alexira [117]

The formula for exponential decay is
$y=a(1-r)^{x}$

where a is the initial value (28750)
r is the rate of decrease (0.12)
x is the time, in this case in years (6 . 2018-2012 = 6 years)

$y=28750(1-0.12)^{6}$

y ≈ 13351.62
