Answer:
you saved $3.20
Step-by-step explanation:
16 x 20/100
16 x 0.2
= 3.20
so 16-3.20= 12.80
final price is 12.80
The probability that he would have done at least this well if he had no ESP is 0.99979
<h3>What is the probability of determining that he would have done well with no ESP?</h3>
To determine the probability, we need to first find the probability of doing well with ESP.
The probability of having 20 correct answers out of 23 coin flips is:

Since we have 20 correct answers, we also need to find the probability of getting 3 answers wrong, which is:

There are
= 1771 ways to get 20 correct answers out of 23.
Therefore, the probability of doing well with ESP is:

= 0.00021
The probability that he would have at least done well if he had no ESP is:
= 1 - 0.00021
= 0.99979

so the answer is B
Step-by-step explanation:
5 squared = 6 squared + x squared
x squared = 36 - 25
x squared = 11
x = radical 11
