Answer:
The answer would be 39 campers.
Step-by-step explanation:
Think about before the 12 campers got off the bus. So, in addition to 27 campers that stayed inside the bus (12+27), it would equal 39 campers in total.
First location the diver dove = 6 3/5 meters below sea leavel.
Second location the diver dove = 8 1/5 meters below sea leavel.
Let us convert those mixed fractions into improper fraction.
6 3/5 =
= 33/5.
8 1/5 =
= 41/5.
Now, we need to find the difference in depths of locations diver dove.
41/5 - 33/5 = ![\frac{41-33}{5}=\frac{8}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B41-33%7D%7B5%7D%3D%5Cfrac%7B8%7D%7B5%7D)
So, we got 8/5.
Now, we need to convert 8/5 into mixed fraction.
Dividing 8 by 5, we get quotient=1 and remainder 3.
So, the mixed fraction would be
.
Therefore, we could say
meter is the difference in depths of locations diver dove.
Answer:
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the complement rule and with the normal standard distribution table:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the lenghts of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
