Answer:
Vulerability and Risk
Explanation:
Uncertainity is the vulnerability of an outcome and is not quantifiable whereas the risk is that the firm will be affected by an outcome which is quantifiable. So here the vulnerability of a system is its misconfiguration that has a loophole which would affect the firm and the hacker can hack these systems easily. Whereas the risk that the hacker will exploit the misconfiguration opportunity, such a hack using system misconfiguration is quantifiable and can be measured from past data and system configuration and security measures.
Let X be the time or period needed for an automobile center to finish an oil change.
X ∼ N (17, 2.5)
a)
P(X ≥ 20) = P((X - 17)/5 ≥ (20- 17)/2.5) = P(Z ≥ 1.2) = .1151 *100 = 11.51% is the answer
b)
P(X ≥ x) = 0.07
P (X - 17)/2.5 ≥ (x - 17)/2.5) = 0.07
P (Z ≥ z) = 0.07
look at the z table, 0.07 lies between 1.47 and 1.48, add and then divide you'll get:z = 1.475
1.475 = (x - 17)/2.5
x = 20.6875 ≈ 21 minutes
Answer:
Explanation: Cellular respiration is the process of breaking down sugar to give energy. It can also be said to be the process of takes in food thereafter using the food taken in it to create ATP (a chemical which the cell uses for energy).
This process starts when a glucose molecule(from consumed food) is converted into carbon dioxide and how its energy is harvested as ATP.
It involves 4 steps which are:
1. Glycolysis: Here, glucose undergoes a chemical transformation which at the end is converted to molecules of pyruvate.
2. Pyruvate Oxidation: At this step the pyruvate produced from glucose above is converted into a two-carbon molecule to Coenzyme A, known as acetyl CoA. Here carbon dioxide is produced as well.
3. Citric acid cycle: At this step, the acetyl CoA produced above combines with a four-carbon molecule and goes through a cycle of reactions. This reactions produces four carbon starting molecules which are: ATP, NADH, FADH
2 and carbon dioxide.
4. Oxidative phosphorylation: Here, the molecules produced above NADH, FADH
2 deposit their electrons in the electron transport chain thereby releasing energy. At the end of the electron transport chain, oxygen accepts electrons and takes up protons to form water.
