Sun Gives off UV rays which are harmful to the human skin causing the cells to get damaged which can cause a mutation in the cell why the Flashlight give off light based on battery’s and an Electrical system
Answer:
It takes 10.5 minutes to kill all the bacteria.
Only 1 cell would remain after 9 minutes.
Explanation:
It will take 1.5 minutes to kill 90% of the cells. So, after 1.5 minutes, only 10% would remain. After 3 minutes, only 1% remain. So, to figure out how long it would take to kill a million cells, we have to multiply 1 million by 0.1 repeatedly until the final value is less than 1 that is because when the value is less than 1, it means there are no more bacteria.
So:
= 0.1
So, you need 10.5 minutes of killing to kill one million cells.
Time taken= 7 x 1.5 minutes = 10.5 minutes.
After 9 minutes you would have:
= 1 cell left
Organic materials continue to be the largest component of MSW. Paper and paperboard account for 27 percent and yard trimmings and food account for another 28 percent. Plastics comprise about 13 percent; metals make up 9 percent; and rubber, leather, and textiles account for 9 percent.
This is a normal distribution and we can use the standard score to compute for probabilities. We compute the standard score of the given.
z = (x - mu)/sd
z = (2625 - 2600)/50 = 25/50 = 0.5.
Consulting the z-table, P(z <= 0.5) = 0.6915.
P(z > 0.5) = 1 - P(z <= 0.5) = 1 - 0.6915 = 0.3085.
