You toss a fair coin 10000 times. what are the odds of obtaining more than 5100 tails, approximately?
ella [17]
This can be solved by using the normal approximation to the binomial distribution.
mean = np = 10.000 * 0.5 = 5,000
The standard deviation is given by:
S.D.= \sqrt{npq} = \sqrt{5000\times0.5} =50
z=\frac{5100-5000}{50}=2
The probability of obtaining more than 5100 tails is 0.0228 and the probability of obtaining fewer than 5100 tails is 0.9772.
The odds of obtaining more than 5100 tails is therefore:
0.0228:0.9772 = 1:42.86.

Two similar solids have edges of 12 feet and 24 feet. If the smaller
nekit [7.7K]

Answer: 2,160\ ft^3

Step-by-step explanation:

The first step is to find the ratio of the lengths.

According to the information given in the exercise, one the solids has edges of  12 feet and the other solid has edges of 24 feet.

Therefore, the ratio of the length of the smaller solid to the length of the is the following:

k=\frac{24\ ft}{12\ ft}\\\\k=2

Now, the ratio to the volumes of the smaller solid to the other one is the following:

k^3=2^3=8

Then, knowing that the volume of the smaller solid is:

V_s=270\ ft^3

You get that the volime of the larger solid is:

V_l=270\ ft^3*8\\\\V_l=2,160\ ft^3
