How do you find the expected value of X?
For a discrete probability distribution, you add up x*P(x) over all possible values of x, where P(x) is the probability that the random variable X takes the value x. For a continuous distribution you need to integrate x*P(x) with respect to x.
Does the probability that a continuous random variable take a specific value depend on the probability density function?
No. The probability that a continuous random variable takes a specific value is always zero.
If it takes 7 people 8 days to dig a ditch how many people would it take to dig a ditch in 12 a day?
That my friend would take 11 people to dig the ditch. thanku pls. X Wouldn't it be 3 to 4 people? 3.5 to be exact.
How long does it take to drive 112 miles at 70 mph?
It takes 112/70 = 1.6 hours.It takes 112/70 = 1.6 hours.It takes 112/70 = 1.6 hours.It takes 112/70 = 1.6 hours.
How long does it take to drive 240 miles at 50 mph?
It takes 240/50 = 4.8 hours.It takes 240/50 = 4.8 hours.It takes 240/50 = 4.8 hours.It takes 240/50 = 4.8 hours.
Difference between discrete and continuous?
A continuous variable is one that can take any value within an interval (or a set of intervals). A discrete variable is one that can only take certain values.Some further notes:* Often a discrete variable takes integer values, but that is not necessary.* Neither discrete nor continuous variables need be limited to a finite number of possible values.* Frequently, continuous variables are continuous only in principle, and the measuring instruments or recording make them discrete. Eg your height is continuous but as soon as it is recorded as 1.75 cm or 5'9", it is made discrete.
What is an analog signal?
An analog signal is a continuous signal that contains time-varying quantities. Unlike a digital signal, which has a discrete value at each sampling point, an analog signal has constant fluctuations. netonplus.com
What is the difference between continuous sampling and discrete sampling?
Continuous data is data that can theoretically be any amount at all. There may be a maximum and minimum value, but all numbers in between are possible. For instance, the amount of time it takes to complete a task, might be 13.4864 seconds. This makes the time continuous data. Discrete is data that can only be set amounts. For instance, how much money someone has, or how many times they've been to the cinema. You cannot have 13.4864 cents, or have visited the cinema 7.33 times. This is a discrete value.
Example of nominal variable and real variable?
A nominal variable is one where observations are classified to categories eg small, medium and large for t-shirts. A real variable is one that takes numerical values, such as shirt size 12, 14, 16 etc. A real value may be a continuous (as opposed to discrete) variable but the very act of recording the observation usually results in the continuous variable being replaced by a discrete one.
What are your expectations in mathematics?
In probability theory, the expectation of a discrete random variable X is the sum, calculated over all values that X can take, of : the product of those values and the probability that X takes that value. In the case of a continuous random variable, it is the corresponding integral.
Difference between the DFT and the FFt?
A Discrete Fourier Transform is simply the name given to the Fourier Transform when it is applied to digital (discrete) rather than an analog (continuous) signal. An FFT (Fast Fourier Transform) is a faster version of the DFT that can be applied when the number of samples in the signal is a power of two. An FFT computation takes approximately N * log2(N) operations, whereas a DFT takes approximately N^2 operations, so the FFT is significantly faster simple answer is FFT = Fast DFT
What type of conduction takes in unmyelinated axon?
continuous
What is the probability that a continuous random variable takes on a specific value?
Zero.
What type of conduction takes place in an unmyelinated axons?
Continuous conduction.
How do you find the expected value of X?
For a discrete probability distribution, you add up x*P(x) over all possible values of x, where P(x) is the probability that the random variable X takes the value x. For a continuous distribution you need to integrate x*P(x) with respect to x.
How much does a thought weigh?
A thought is a pattern, not a discrete thing made out of matter. As such, it weighs nothing, since it takes mass to weigh anything.
Is there a water cycle when it is cold?
Water cycle is a continuous process. It takes place even when it is cold.
