What do indepeendent variable mean?
The x coordinate. The y coordinate is the dependent variable.
What is the probability of an observation being above the mean?
For a continuous variable it is 0.5 but for a discrete variable the answer depends on the probability of the variable taking the mean value. It is half of the rest of the probability. If the discrete variable X has mean m and Prob(X = m) is p then Prob(X > m) = (1 - p)/2.
What does the word variable mean in mathmatics?
Variable means x=time and y=# of something
What does 9x mean?
9 times a variable x
What does c x b mean?
The variable c times the variable b simply equals cb. Just as the variable x times the variable y would equal xy, and so on.
What does x mean in a math problem?
X could be a sign for multiplication, or it could also be a variable. A variable is a letter representing a number.
The mean of the discrete random variable X is 18.59 What is the variance of X?
23.18
How do you solve the variable x-8 3?
If you mean: x-8 = 3 then x = 11
What do you call signs like or x?
I think you mean ' variable. '
What does x equals 2n mean?
It means that the variable x is twice as much as variable n. x is in direct proportion to n (or x varies directly as n) with the constant of proportionality = 2.
What does define mean in math terms?
The mean is sometimes also known as the arithmetic average. For a finite number of observations, it is he sum of their values divided by the total number. It can also be described as the expected value of a variable. If a discrete numerical variable X can take the values x, then the mean is the sum [x*pr(X = x)] where the summation is over all possible values of x. For a continuous variable, replace the summation by integration.
What does a cumulative relative frequency of .4 mean?
If the cumulative relative frequency when the variable X takes the value x, it means that 0.4 (or 40%) of the values of the variable X are less than or equal to x.
