Answer:
2 1/5
Step-by-step explanation:
First you make both fractions into 5 becomes 25/5. 2 4/5 becomes 14/5. Then you would just subtract 25/5 - 14/5 = 11/5 then make it a mixed number 2 1/5.
I think it’s 25???? i tried haha
It’s the first one, the coin wasnt flipped enough times
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.
