Answer:
0.6 = 60% probability that a randomly selected application from this distribution took less than 18 minutes.
Step-by-step explanation:
Uniform probability distribution:
An uniform distribution has two bounds, a and b.
The probability of finding a value of at lower than x is:
The probability of finding a value between c and d is:
The probability of finding a value above x is:
Uniform distribution between 15 and 20 minutes.
This means that
What is the probability that a randomly selected application from this distribution took less than 18 minutes?
0.6 = 60% probability that a randomly selected application from this distribution took less than 18 minutes.
Answer: No
Step-by-step explanation:
This is not an isosceles triangle because there are different angle measurements. The rule of an isosceles triangle is that it must always have two equal sides and angles.
