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".
Part a
Let X the random variable of interest for this case. We define the z score with the following formula:
And for this case we know that 
If we solve for x from the z score formula we got:

And replacing we got:

Part b
Let X the random variable of interest for this case. We define the z score with the following formula:
And for this case we know that 
If we solve for x from the z score formula we got:

And replacing we got:

Part c
Let X the random variable of interest for this case. We define the z score with the following formula:
And for this case we know that 
If we solve for x from the z score formula we got:

Answer:
6 team members
Step-by-step explanation:
<h3>We know that 2 team members can solve 13 problems in an hour. So, all you have to do is find what 39÷13 is, and multiply that by 2.</h3><h3>
</h3><h3>39÷13= 3</h3><h3 /><h3>3*2= <u>6</u></h3><h3>And we have our answer!</h3><h3><u /></h3><h3>I hope this helps! If it did, it would mean a lot to me if you could mark me brainliest :D</h3><h3 /><h3>Have a nice day!</h3>
Answer:
(-6, -3)?
Step-by-step explanation:
The value of c is { c | c ∈ R, c ∉ {-1,0,2,12} }.
c is a number such that it is not in the set {-1,0,2,12} else we end up with a domain value having multiple range values, contradicting with the definition of a function.
