I need help ASAP!!! Which of the following represents a valid probability distribution?
2 answers:
Answer:
Probability distribution B
Step-by-step explanation:
Probabilities cannot be negative numbers. This means we can exclude distributions A and C.
Probability can be a maximum of 1.0. This means we can eliminate distribution D.
This leaves distribution B.
We can double check by finding the sum of the distribution. The sum of a probability distribution is 1.0. Adding these probabilities together, we have
0+0.45+0.16+0.39 = 1.00
B is correct.
The answer is the second option, just took the test.
answer is B

Answer:
x²/121 + y²/21 = 1
Step-by-step explanation:
x²/a² + y²/b² = 1
a = 11
c² = a² - b²
b² = a² - c²
b² = 11² - 10²
b² = 21
x²/11² + y²/21 = 1
x²/121 + y²/21 = 1
Answer:
Her monthly salary is $4395.83
Step-by-step explanation:
Annual = 12 months
12 months = $52 750
1 month = $52 750 ÷ 12
