Viktor [21]

Answer:

0.1151

Step-by-step explanation:

Given that a laptop company claims up to 10.1 hours of wireless web usage for its newest laptop battery life. However, reviews on this laptop shows many complaints about low battery life. 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

=P(X\geq 10.1)\\=P(Z\geq \frac{10.1-9.5}{0.5} )\\= P(Z\geq 1.2)\\=0.1151

we get the probability that the battery life is at least 10.1 hours is 0.1151

Volgvan

• Im sorry but we doesnt know the x number :( but dont worry to plot the diagram:

- substitute the number x (given) into the equation f(x)

- example: f(x) = x + 9 / x - 3

- then x given is 4

- therefore, f(x) = (4) + 9 / (4) - 3

- f(x) = 13 / 1 or 13

- then you plot at 13 on the graph :)

hope this helps ;/
