Answer: a^8-b^8
Step-by-step explanation:
Answer:
b = 45 / 4 = 11 1 /4.
Step-by-step explanation:
We are dealing with a (30,60,90)-triangle, therefore z = 15 sqrt(3) / 2. So as well b = (15 sqrt(3) / 2) sqrt(3) / 2 = 45 / 4.
Answer: The first one or the second one but its the first one....
Step-by-step explanation:
Answer:
4.76% probability that a randomly selected person from the population has a positive test result
Step-by-step explanation:
We have these following probabilities:
4% probability of having the disease.
If a person has a disease, 95% probability of a positive test.
100-4 = 96% probability a person does not have the disease.
If a person does not have the disease, 1% probability of a positive test.
What is the probability that a randomly selected person from the population has a positive test result
95% of 4% and 1% of 96%. So
p = 0.95*0.04 + 0.01*0.96 = 0.0476
4.76% probability that a randomly selected person from the population has a positive test result
Answer:
Therefore, the final form
p+/-E = 0.666+/-0.333
Step-by-step explanation:
Given:
Confidence interval = 0.333 < p < 0.999
To express the confidence interval in the forn p+/-E, where;
p is the midpoint of the confidence interval
E is the error.
The midpoint of the confidence interval is
p = (0.333+0.999)/2 = 1.332/2
p = 0.666
The error can be calculated using the formula:
Error = interval width/2
E = (0.999-0.333)/2 = 0.666/2
E = 0.333
Therefore, the final form
p+/-E = 0.666+/-0.333
