Let n be the number of expected free throw until she makes the first throw.
Suppose the number of throws are 10, Then she will make 8 of the 10 throws. On 5 throws, she make 4 (80% of 5) and on 2 throws, she makes 1.6, it means one throw. We deduce that the expected number of free throws until she makes one is 2.
It is rational because it is not negative
Answer:
10.48 miles.
Step-by-step explanation:
That is 4/5 * 13.1
= 10.48 miles.
So, we have two equations. The first one is a/b = 2, and the other one is to find the value of 4b/a. In order to solve this, let's find the value of b/a. As you can observe, b/a is the reciprocal of a/b. Therefore, b/a is also the reciprocal of 2. This means that b/a = 1/2. Now, substituting this to the second equation, the answer would be
4b/a = 4(1/2) = 2
The answer is 2.
