Step-by-step explanation:
-|-5|-|-7-28| The given equation.
-|-5|-|-35| The absolute value "|" sign is just like the parenthesis.
-5-35 "Convert" the numbers in between the absolute value signs to positive numbers because the absolute value means how many values away from zero. It cannot be a negative.
-40 Solve!
5000
First, let's determine how many standard deviations from the mean the value
(163+1) = 164 is:
(164 - 125)/15 = 39/15 = 2.6
Now using a standard normal table, look up 2.6 to determine the percentage of points that would be that far from the mean. I find a value of 0.49534. Note that is is a half value. So the percentage that will be higher than that will be 0.5 - 0.49534= 0.00466
Now multiply by the number of points overall, getting
0.00466 * 1000000 = 4660
So there will be approximately 5000 pixels brighter than 163 gray levels.
