The fourth listed answer:
Domain: All Real numbers
Range : { f{x) | f(x) 0, f(x) = 1 }
Step-by-step explanation:
The domain consists of all Real numbers (notice that you have a well defined f(x) value for all possible x on the horizontal axis.
The Range is associated with the set of those f(x) values (on the vertical axis) that are connected via the functional relationship with a value "x" of the domain. The line with positive slope extends to all f(x) values that are 0 (smaller than or equal to zero). While the flat horizontal line on the right of the plot corresponds to the line f(x) =1 (only one value of f(x) [1} connects with the x-values of the Domain that are larger than 3.
We seems to be being asked the probability of rolling at least one four in fifty tries, which should be pretty high. As usual with "at least" questions, we write
p = P(at least one 4) = 1 - P(no fours at all)
The probability of a four on one roll is of course 1/6, so the probability for "not a four" is 1-1/6=5/6. We want the probability of a conjunction of 50 independent events: no four on the first roll and no four on the second roll and...
For a conjunction of independent events we multiply their probabilities. That's 5/6 times itself 50 times. So our answer is
If we need a decimal approximation, it's
1. You can call to the cost of each one of Tanya's items and
to the cost of each one of Tony's items.
2. Based on the information given in the problem and knowing that both paid the same amount of money, you can write the following expression:
3. You must solve for :
4. The total amount of money that Tanya and Tony paid was:
dollars
5. Therefore, the amount of money that Tony paid for each item was:
dollars
The answer is: The individual cost of each Tanya's items is dollars and the individual cost of each Tony's items is
dollars.
