The student will analyze data following a normal distribution.
Given
The life of Sunshine CD players is normally distributed with a mean of 4.1 years and a standard deviation of 1.3 years. A CD player is guaranteed for 3 years. We are interested in the length of time a CD player lasts.
Normal distribution
Define the Random Variable
in words.
~
Find the probability that a CD player will break down during the guarantee period.
Sketch the situation. Label and scale the axes. Shade the region corresponding to the probability.
(Use zero (0) for the minimum value of x.)
Find the probability that a CD player will last between 2.8 and 6 years.
Sketch the situation. Label and scale the axes. Shade the region corresponding to the probability.
Find the 70th percentile of the distribution for the time a CD player lasts.
Sketch the situation. Label and scale the axes. Shade the region corresponding to the lower 70%.
Bacteria doesn't produce energy they are dependent upon their substrate in case of lack of nutrients they are able to make spores which helps them to sustain in harsh environments
_Adnan
But not all bacteria make spores, l mean Eukaryotic cells have Mitochondria which acts as powerhouse for them, since bacteria don't have it, what is the substitution for it?
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
There are nothing like emergency disease but there are some common medical emergency which can occur simultaneously like Bleeding,heart attack,Breathing difficulties,severe pain heart stock.Hope you will get my point .Have a nice day ❣️
