Answer:
The answer is "2793 miles"
Step-by-step explanation:
In this firstly we convert degrees to radians, which can be defined as follows:


Now calculating the distance:


The triangle to solve for has a leg or 12 feet, hypotenuse of 20 feet, so solve for Pythagoras

for a

a = 16 feet
Answer:
0.3898 = 38.98% probability that there will be 4 failures
Step-by-step explanation:
A sequence of Bernoulli trials forms the binomial probability distribution.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
Let the probability of success on a Bernoulli trial be 0.26.
This means that 
a. In five Bernoulli trials, what is the probability that there will be 4 failures?
Five trials means that 
4 failures, so 1 success, and we have to find P(X = 1).
0.3898 = 38.98% probability that there will be 4 failures
The answer is 4.7 x 10^-4
If you move the decimal to the right, the exponent will be negative. If you move it to the left, the exponent will be positive.
