Answer:
a) 0.4286 = 42.86% probability that the battery life for an iPad Mini will be 10 hours or less
b) 0.2857 = 28.57% probability that the battery life for an iPad Mini will be at least 11 hours
c) 0.5714 = 57.14% probability that the battery life for an iPad Mini will be between 9.5 and 11.5 hours
d) 86 should have a battery life of at least 9 hours.
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X lower than x is given by the following formula.
The probability of being higher than x is:
The probability of being between c and d is:
Assume that battery life of the iPad Mini is uniformly distributed between 8.5 and 12 hours.
This means that
a. What is the probability that the battery life for an iPad Mini will be 10 hours or less (to 4 decimals)?
0.4286 = 42.86% probability that the battery life for an iPad Mini will be 10 hours or less.
b. What is the probability that the battery life for an iPad Mini will be at least 11 hours (to 4 decimals)?
0.2857 = 28.57% probability that the battery life for an iPad Mini will be at least 11 hours
c. What is the probability that the battery life for an iPad Mini will be between 9.5 and 11.5 hours (to 4 decimals)?
0.5714 = 57.14% probability that the battery life for an iPad Mini will be between 9.5 and 11.5 hours.
d. In a shipment of 100 iPad Minis, how many should have a battery life of at least 9 hours (to nearest whole value)?
Proportion of iPad Minis with a battery life of at least 9 hours.
Out of 100:
0.8571*100 = 85.71
To the nearest whole number
86 should have a battery life of at least 9 hours.
Answer:
10 m
Step-by-step explanation:
If the area of a square is 50 m2, then the length of each side will be m, to get the diagonal length, after dividing the square by joining the points of the diagonal with a line, it forms two right angles with length
m each.
the diagonal length represent the hypotenuse side of each of the right angle, knowing the pythagoras theorem:
, so we have:
diagonal = 10 m
