The value of z-score for a score that is three standard deviations above the mean is 3.
In this question,
A z-score measures exactly how many standard deviations a data point is above or below the mean. It allows us to calculate the probability of a score occurring within our normal distribution and enables us to compare two scores that are from different normal distributions.
Let x be the score
let μ be the mean and
let σ be the standard deviations
Now, x = μ + 3σ
The formula of z-score is

⇒ 
⇒ 
⇒ 
Hence we can conclude that the value of z-score for a score that is three standard deviations above the mean is 3.

Answer:
13.31 x 
Step-by-step explanation:
So, if we take the two equations, and add the normal numbers together, we have: 5.97 + 7.34 = 13.31
Then if we add the two tens together it would be:
+
= 10 to the power of 46.
The equation would be 13.31 x
