<h2>Answer:</h2>
The probability that it will land in the unshaded region in the nearest percent is:
67%
<h2>Step-by-step explanation:</h2>We know that a full circle covers a angle of 360° or 2π radians.
The angle that is covered in the unshaded region is: 240°
Hence, the probability is calculated as the ratio of the number of favorable outcome to the total number of outcomes.
The probability in percentage that the dart will land in the unshaded region is:
<em> Ratio of the angle of unshaded region to the angle of the total circle.</em>
Hence, to the nearest percent the probability is:
67%

Answer:
Step-by-step explanation:
given that a laptop company claims up to 11.0 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 10.5 hours and standard deviation 27 minutes.
convert into same units into hours.
X is N(10.5, 0.45)
a) the probability that the battery life is at least 11.0 hours
(b) the probability that the battery life is less than 10.0 hours
=
(c) the time of use that is exceeded with probability 0.97
=97th percentile
= 11.844
d) The time of use that is exceeded with probability 0.9 is
is 90th percentile = 10.885
To find the sum:
Therefore the answer is a^3+12a^2+14a+5.
