I'm sorry but I don't see any questions?
Twenty-seven minus 3/2of a number (x) is not more than 36.
27 - (3/2)X = 36
What is the number?
(3/2)X = 27 - 36 = - 9
X = (- 9x2)/3 = -18/3 = -6
Check
36 = 27 - (3/2)X = 27 - (3/2)x(-6) = 27 - (-18/2) = 27 - (-9) = 36
The difference between 100 and 75 is 25.

First, lookup a standard normal table and see what the z-score is for 0.025 (one half of 100% - 95%) to allow for equal sized tails. You should find that the z-score is 1.96. That means that 95% of the time, the value should be within 1.96 standard deviations of the mean. Now let's calculate the standard deviation.
800 is 800 - 1200 = -400 to the left of the mean of 1200.
1600 is 1600 - 1200 = 400 to the right of the mean of 1200.
So we are an equal distance of 400 on both sides of the mean. And we know from the z-score of 1.96, that we're 1.96 standard deviations from the mean. So a little division will give us the standard deviation. Which is:
400 / 1.96 = 204.0816327
So the standard deviation of the light bulbs is 204</span>
