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
=

Answer:
50
Step-by-step explanation:
Angle 1 is 110.
Angle 3 is 2x plus 10.
Angle 1 and 3 are vertically opposite angles.
And vertically opposite angles r equal.
Which means, angle 1=angle 3,and angle 2=angke 4.
Here we only Need angle 2 and 3.
Angke 2= angle 3.
Which is 2x plus 10=110.
Therefore 2x=110-10=100
Therefore x = 100÷2=50
There u have it ma'am.
