Answer:
<h3>Therefore, So the correct answer is 0.3446</h3>
Step-by-step explanation:
Suppose parts A and B have a lifetime that is normally distributed with mean 110 hours and standard deviation 5 hours. Suppose further that parts A and B work independent of each other. What is the probability that the electric device works more than 112 hours
Here it is given that distribution is normal with
mean = 110 and standard deviation = 5
Now we need to find
P (x > 112)
As distribution is normal we can convert x to z
<h3>Therefore, So the correct answer is 0.3446</h3>

Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
Use the points to find a and b, that is
(2, 18)
18 = a → (1)
(4, 162)
162 = a → (2)
divide (2) by (1)
= = 9
b² = 9 ⇒ b = 3
substitute b = 3 into (1)
18 = 9a ⇒ a = 2
y = 2 ← exponential equation
