Answer:
And we can find this probability on this way:
We expect around 68.27% between the two scores provided.
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 scores of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
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 on this way:
We expect around 68.27% between the two scores provided.
Ok here’s the equation you can run on the next one
A=P(1+rt) A is total P is current amount or starting amount r is annual interest and t is the amount of time
Your answer is
$297.60

Step-by-step explanation:
mark as Brainlist
If a+b= 2+11 then your sum will be 13.
heres an example...
If you have eleven dollars and I give you 2 more you can simply count up 2 more from 11 leaving you at 13.
you're welcome.
