The Excel WEEKDAY function takes a date and returns a number between 1-7 representing the day of week. By default, WEEKDAY returns 1 for Sunday and 7 for Saturday. You can use the WEEKDAY function inside other formulas to check the day of week and react as needed.
Here we are going to see how to determine if the given table of data represents the exponential function or not. One method is to observe the shape of the graph. But the graph of an exponential function may resemble part of the graph of a quadratic function. Another way is to use the problem-solving strategy look for a pattern with the data.
Put simply, it is a function which tells you the probability of certain events occurring. The usual notation that is used is P(X = x) = something. The random variable (r.v.) X is the event that we are considering. So in the above example, X represents the number of heads that we throw. So P(X = 0) means "the probability that no heads are thrown".
Answer: A method to distinguish functions from relations. The vertical Line test. is a way to determine if a relation is a function. states that if a vertical line intersects the graph of the relation more than once, then the relation is a NOT a function. If you think about it, the vertical line test is simply a restatement of the definition of ...
And for it to be a function for any member of the domain, you have to know what it's going to map to. It can only map to one member of the range. So negative 3, if you put negative 3 as the input into the function, you know it's going to output 2. If you put negative 2 into the input of the function, all of a sudden you get confused.
The normal distribution density function f(z) is called the Bell Curve because it has the shape that resembles a bell. Standard normal distribution table is used to find the area under the f ( z ) function in order to find the probability of a specified range of distribution.
We are asked to find which of the following table represent an linear function. As the x-value is increasing by a constant value i.e. '1'. Hence, for the function to be a linear function the value of y must also increase or decrease by the same constant. This means the difference in the y-value from the preceding y-value must be same. 1)
