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.
The multiplicative inverse of -2/5 is -5/2
Answer:
|3| < |-7| and 3>-7
Step-by-step explanation:
The absolute value of -7 = 7, and 3 < 7.
Substitute the value of x into the expression,
y = 8 - 2x
y = 8 - 2(8)
y = 8 - 16
y = -8
In short, Your Answer would be -8
Hope this helps!
Answer:
Approximately the number of men is 203 and number of women is 47.
Step-by-step explanation:
It is given that the United States Air Force has 19 women for every 81 men enlisted.
It means the ratio between men and women is 81:19.
Sum of ratio is

Therefore for each 100 people, there are 81 men and 19 women.
Total number of peoples is 250.

In 250 members the number of men is

The numbers of persons cannot be a fraction values or a decimal value, therefore the number of men is 203.
In 250 members the number of women is

Therefore approximately the number of men is 203 and number of women is 47.
