Answer:
We have 2 1/2 = 5/2 miles;
Then, (5/2) x (3/4) = 15/8 = 1 7/8 hours;
Step-by-step explanation:
Hello,
(u+v)^4= u^4+4^3v+6u²v²+4uv^3+v^4
with u=2x² and v=y²
(2x²+y²)^4=
16x^8 + 32x^6*y² +24x^4y^4 +8x²y^6 + y^8
Using it's concept, the experimental probability that in a group of 4 students, at least one of them has green eyes is of 0.45 = 45%.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>. An experimental probability is calculated considering the results of previous trials.
In this problem, there were 20 trials. The digit 9, which represents a student with green eyes, appears at least once in 9 of the the trials, hence the probability is:
p = 9/20 = 0.45 = 45%.
