Solving for 'y'
2x - 2y + 5 = 0
Add 2y on both sides
2x + 5 = 2y
Divide by 2 on both sides
y = x + 5/2
y = x + 2.5
Solving for 'x'
2x - 2y + 5 = 0
Subtract 2x on both sides.
-2y + 5 = -2x
Divide 2x on both sides
x = y - 5/2
x = y - 2.5
Hi there, 18÷1000=.018. Therefore, the answer is .018
Answer:


Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Middle 85%.
Values of X when Z has a pvalue of 0.5 - 0.85/2 = 0.075 to 0.5 + 0.85/2 = 0.925
Above the interval (8,14)
This means that when Z has a pvalue of 0.075, X = 8. So when
. So




Also, when X = 14, Z has a pvalue of 0.925, so when 




Replacing in the first equation





Standard deviation:
