Find the surface area of the pyramid.
Monica [59]

Answer:

306 mi^2

Step-by-step explanation:

surface area = area of base + lateral area

surface area = s^2 + 4bh/2

surface area = (10 mi)^2 + 4(10 mi)(10.3 mi)/2

surface area = 306 mi^2

What is the probability of obtaining 5 heads from 5 coin flips? Give your answer to 5 decimal places.
katovenus [111]

Answer:

0.03125 = 3.125% probability of obtaining 5 heads from 5 coin flips.

Step-by-step explanation:

For each coin flip, there are only two possible outcomes. Either it is heads, or it is tails. The probabilities for each flip are independent from each other. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

In this problem we have that:

For each coin toss, heads and tails are equally as likely, so p = \frac{1}{2} = 0.5}

What is the probability of obtaining 5 heads from 5 coin flips?

This is P(X = 5) when n = 5.

So

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 5) = C_{5,5}.(0.5)^{5}.(0.5)^{0} = 0.03125

0.03125 = 3.125% probability of obtaining 5 heads from 5 coin flips.
