If the population was 40,000 at the beginning of 2009, at the end of 2009 it has increased by 10% and became 44,000.
By the same way, at the end of 2010, it became
At the end of 2011, the population was
Well the formula for finding the volume of rectangular prisms, is length x width x height, so any 3 numbers multiplied by each other that equal 64 could be the measurements. For example, a length of 2 units, height of 2 units and a width of 16 units has a volume of 64 so that could be your answer.
Answer:
b. 2.333
Step-by-step explanation:
Test if the mean transaction time exceeds 60 seconds.
At the null hypothesis, we test if the mean transaction time is of 60 seconds, that is:
At the alternate hypothesis, we test if it exceeds, that is:
The test statistic is:
In which X is the sample mean, 
is the value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.
60 is tested at the null hypothesis:
This means that 
A sample of 16 ATM transactions shows a mean transaction time of 67 seconds with a standard deviation of 12 seconds.
This means that 
Value of the test statistic:
Thus, the correct answer is given by option b.

Suppose the 3 squirrels all wanted to store acorns for the winter.
Depending on how motivated. Each squirrel was they would end up with
different amounts. For instance suppose the brown squirrel took 4 trips,
the gray squirrel took 2 trips, and the black squirrel took 2 trips.
The Brown squirrel would end up with 8 acorns, the gray squirrel would
have 6 acorns and the black squirrel would have 10. Between them they
took every one of the 24 acorns.
Hope it helps.
