Answer:
Two standard deviations
Step-by-step explanation:
The Z score is obtained using the mean and standard deviation, according to the empirical. Rule, which gives percentage of values that lie within an interval estimate in a normal distribution ;
one standard deviation lie within 68% of the mean
Two standard deviations lie within 95%
Three standard deviations lie within 99.7%
Hence, for the question given, 95% fall within 2 standard deviations of the mean

Answer:
y = -4
Explanation:
The initial expression is:
-13 = 4y + 3
So, we need to substract 3 from both sides of the equation:
-13 - 3 = 4y + 3 - 3
-16 = 4y
Then, dividing both sides by 4, we get:
-16/4 = 4y/4
-4 = y
Therefore, the solution of the system is y = - 4.
