Answer: 0.3439
Step-by-step explanation:
Given :The last four digits for telephone numbers are randomly selected (with replacement).
Here , each position can be occupied with any of the digit independently .
Total digits = 10
Total digits other than 0 = 9
For each digits , the probability that it is not 0 =
If we select 4 digits , The probability of getting no 0 =
(By multiplication rule of independent events)
Now , the probability that for one such phone number, the last four digits include at least one 0. = 1- P(none of them is 0)
=1- 0.6561=0.3439
Hence, the probability that for one such phone number, the last four digits include at least one 0. is 0.3439 .
Answer:
There are Even, Odd and None of them and this does not depend on the degree but on the relation. An Even function: And Odd one:
Step-by-step explanation:
1) Firstly let's remember the definition of Even and Odd function.
An Even function satisfies this relation:
An Odd function satisfies that:
2) <u>Since no function has been given</u>. let's choose some nonlinear functions and test with respect to their degree:
3) Then these functions are respectively even and odd, because they passed on the test for even and odd functions namely, and
for odd functions.
Since we need to have symmetry to y axis to Even functions, and Symmetry to Odd functions, and moreover, there are cases of not even or odd functions we must test each one case by case.
