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.
Answer:
7
Step-by-step explanation:
solving algebraically:
(x = the unknown number)
(our goal is to isolate x/get x by itself)
2x + 5 = 5x - 16 {equation written out}
-2x -2x
5 = 3x - 16
+ 16 + 16
21 = 3x
÷3 ÷3
7 = x
check:
(2)(7) + 5 = (5)(7) - 16
14 + 5 = 35 - 16
19 = 19
