Answer: 0.0497870 ; 0.87754
Step-by-step explanation:
Given that :
λ = 0.0003
Defining a continuous distribution function :
F(x) = 1 - e^-λx = 1 - e^-0.0003x ; x ≥ 0
a. What proportion of the fans will last at least 10,000 hours?
P(x ≥ 10000) = e^-0.0003(10000) = 0.0497870
b. What proportion of the fans will last at most 7000 hours?
P(x ≥ 7000) = 1 - p(x ≤ 7000) = 1 - e^-0.0003(7000)
1 - 0.12245642825 = 0.87754

Answer: x = -8
Step-by-step explanation:
Move all terms that don't contain x to the right side and then solve
Answer:
(2 1/4, 1 1/2) A
(-1 1/4, 1 1/2) B
(-2 1/2, 1/4) C
Step-by-step explanation:
We can determine that each tick mark represents 1/4 based off the given numbers. Now we just determine the points.
(2 1/4, 1 1/2) A
(-1 1/4, 1 1/2) B
(-2 1/2, 1/4) C
