How do you find the standard deviation of a uniform distribution? The standard deviation of X is σ=√(b−a)212. The probability density function of X is f(x)=1b−a for a≤x≤b. The cumulative distribution function of X is P(X≤x)=x−ab−a. How do you find the standard deviation of a random variable X? For a discrete random variable the standard […]

How do you create a node in a linked list? make the last node => next as the new node. Declare head pointer and make it as NULL. struct node { int data; struct node *next; }; struct node *head = NULL; Create a new node. If the head node is NULL, make the new […]

What is axial coding in Grounded Theory? Within and inspired by grounded theory, axial coding is the process of relating pieces, or codes, of data to each other. In particular, axial coding makes connections between categories that reveal themes, new categories, or new subcategories. What is a grounded theory approach to research? Grounded theory is […]

What are the 4 uses of energy? We divide our energy use among four economic sectors: residential, commercial, transportation, and industrial. Heating and cooling our homes, lighting office buildings, driving cars and moving freight, and manufacturing the products we rely on in our daily lives are all functions that require energy. What do we use […]

What causes high total harmonic distortion? Harmonic distortions are usually caused by the use of nonlinear loads by the end users of electricity. Nonlinear loads, a vast majority of which are loads with power electronic devices, draw current in a nonsinusoidal manner. What does total harmonic distortion mean? From Wikipedia, the free encyclopedia. The total […]

When removing and replacing piston rings on a cast aluminum alloy piston, the technician should: Use the old ring and a feeler gauge to measure piston ring groove clearance. When installing a piston assembly the notch on the head […]

Why is poop hot sometimes? What’s hot going into your body is likely to be hot coming out. Spicy foods often contain natural substances, such as capsaicin, which impart a fiery flame to your tongue — and they do much the same to your anus during a bowel movement. What does your poop consist of? […]

What does the 1 stand for in E7018? The “E” in E7018 electrode indicates a tool used for an arc-welding process. The 70 means it makes welds that are very strong (70,000 psi). The 18 means two things: The “1” means the electrode can be used in any position, and the “18” means low hydrogen […]

How do you find the multiplicity of a root? The number of times a given factor appears in the factored form of the equation of a polynomial is called the multiplicity. The zero associated with this factor, x=2 , has multiplicity 2 because the factor (x−2) occurs twice. The x-intercept x=−1 is the repeated solution […]
