A survey on battery life reported by customers shows that it follows a normal distribution with mean 9.5 hours and standard deviation 30 minutes.
If X is the battery life then X is N(9.5, 0.5)
(we convert into one unit for calculations purpose here hours)
a) the probability that the battery life is at least 10.1 hours
=
we get the probability that the battery life is at least 10.1 hours is 0.1151

Answer:
A.
Gradient: 4
x-intercept: (1,0)
y-intercept: (0,-4)
B.
Gradient: - 3
x-intercept: (-1,0)
y-intercept: (0,-3)
Line y=5x=40
x-intercept: 8
y-intercept: 40
Step-by-step explanation:
y -5x = 40
x-intercept: 0-5x=40
-5x = 40. x = 40/-5
x = -8
y-intercept: y -0 = 40
y = 40
