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.
What is X2 equals 100?
"x2 = 100" is an equation which, if solved for x, will give you two possible value: 10 and -10.
How do you complete a table of values with the equation -2y 6x-2?
Given a value for the variable x, you find (calculate) the corresponding value of y. These (x, y) pairs are part of the table. You cannot complete the table because there are infinitely many possible values of x.
If x equals 3 What is the value of x?
the value of x is 3
What is the absolute value of x minus the absolute value of x?
zero. The absolute value of a number is just the positive version of that number, so the absolute value of x is x, and x minus x is zero.
What is x if multiply by zero and result is 1275?
There is no possible value of x that will satisfy the given equation. There is no possible value of x that will satisfy the given equation. There is no possible value of x that will satisfy the given equation. There is no possible value of x that will satisfy the given equation.
What is the maximum possible value of x?
If x is the unknown or variable in an equation it can have many possible maximum or minimum values
What are the possible solutions for an absolute value equations?
Positive X or Negative X
What does it mean to find the value of x?
Given a situation, what are the possible values of X is what it is asking.
What is the absolute value of x equals -x?
It is not possible to be certain. If x >= 0 then abs(x) = x if x < 0 then abs(x) = -x
What is the smallest possible absolute value?
There is no such value since rational and irrational numbers are infinitely dense. If there was a positive number, x, that laid claim to having the smallest possible absolute value, it would immediately be challenged by x/2. Then that, in turn, would be challenged by x/4, and then x/8 and so on, and on, and on.
Let the function f x be defined by f x 2x-3 If p is real number what is one possible value of p for which f p p?
The only possible value of p is 3.
Pre increment and post increment?
Both increment the value of the variable by one. The difference is the value of the increments expression itself. With preincrement value is taken after incrementing, and with postincrement value is taken before incrementing. Example: Let x have value 5. y = ++x; Both y and x are assigned value 6. Again let x have value 5. y = x++; y is assigned value 5. x is assigned value 6.
For which value of x is the equation 2(1 plus x) x plus 3 true?
Without an equality sign the given terms can't be classed as an equation and so therefore finding the value of x is not possible.
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.
Which inequality has x0.8 as one of its solutions?
One possible inequality that has x = 0.8 as a solution is x ≤ 0.8. This means that any value of x that is less than or equal to 0.8 will satisfy the inequality.
The sum of x and 8 is less than 72 find all possible values of x?
-1 < x < 64, but if x is less than 0 then x can be any value.
