Given the following which is the mean and standard deviation of
the dune’s movement over one year and need to find out what the ten year mean
and the standard deviation will be.
The ten-year mean is ten times the one year mean or 110 feet per
decade. The ten-year standard deviation is somewhat more complicated. Multiple independent
trials accumulate standard deviation as the square root of the number of trials
since an unusually high level of movement ten years in a row. The decade is
going to be 2 feet per year x square root of ten will result to 6.32 feet.
The answer will to question A. will be:
<span> 90 < 110 + z (6.32 feet)</span>
<span> -20 < z (6.32 feet)</span>
<span> z > - 3.16</span>
<span>By using the z table, it shows the probability of 0.9992. This
result shows that as 90 feet is lesser than the mean travel that is expected
over decade. </span>
It is: 27/8 = 3 with a remainder of 3
Answer:
82
Step-by-step explanation:
you multiply 4(25)
which is 100

Answer:
10 fruit snacks were in the packet.
Step-by-step explanation:
lets look at the numbers, we have 5 and 2. your answer is 8 because 5x2=10
it would basiclly be the same as dividing. say your question was you have a packet of fruit snacks, there are 10 fruit snacks in the packet and 4 friends and you how many did you each have the answer would be 2.
your probably wondering why its 5 and not 4 well the question says... You had a bag of fruit snacks that you shared with 4 friends, it says you shared so that is why its 5 and not 4.
HOPE THIS HELPS!!!!!! :)
