Answer = 2.00
Z score is a statistical that corresponds to the standardization of the regular score to a normal distribution
The formula for Z score is Z = [X - mean ]./ (standard deviation)
Here X = 930.00; mean = 900.00; and standard deviation = 15.00
Then, Z = [930.00 - 900.00] / 15.00 = 30.00 / 15.00 = 2.00
Therefore, your answer is 2.00
Hope I helped :)
Explanation:
For every problem, plug in the number where the variable is.
For example:
Evaluate the following expression by substituting 8 for x.
x + 9
You would take the x and turn it into 8, then you would do 8 + 9.
Answer:
117 units cubed.
Step-by-step explanation:
I have attached the work to your problem.

3x = 9y
9y = 3x
y = 3x/9
y = 1/3x
<span>The slope is 1/3</span>
If you want to find the probability, just make a fraction of the number of times that outcome happened over the total amount of tests:
Open: 3/50= 0.06 or 6%
Closed: 7/50=0.14 or 14%
Side: 40/50= 0.8 or 80%
Hope this helps!
