Answer: C. 82.26%
Explanation:
Given : The red blood cell counts of women are normally distributed with
Let X be the random variable that represents the red blood cell counts of randomly selected woman.
Z-score : 
For X=4.2
For X=5.4
Now, the probability that the women have red blood cell counts in the normal range from 4.2 to 5.4 million cells per microliter will be :-
Hence, 82.26% of women have red blood cell counts in the normal range from 4.2 to 5.4 million cells per microliter.
Petroleum Products
Petroleum and its products are mainly composed of carbon polymers (chains), as the backbone, with different structural and functional groups. Plastic, for example, is made of polypropylene and polybutylene which is mainly made of carbon atoms, whose monomers are linked in a chain to form polymers that make up the products.
Synthetic rubber on the other hand is made of copolymers of carbon and other addictives such as styrene. Synthetic fiber is made of nylon that is composed of a copolymer between carboxylic acid and amides.
The molecules in the sugar move from an area of higher concentration (sugar cube) to an area of lower concentration in the water.
That is exactly what diffusion is: the net movement of molecules or atoms driven by a gradient , which means that it doesn’t requires energy.
Answer:
its 30 N
since it didn't change it stays the same 30N.
