Answer:
Wait. Then you try it again
Explanation:
You wait and try again later and if this still persists, you may have to check the optical drive from the drive manager peradventure there is an issue there probably a software issue, also you may have to clean the optical drive using the cleaner disc, likewise you may need to test an old disc on the optical drive to be sure the fault is not from the disc you inserted.
Solution:
Running computer programs and their data are stored in Rom.
ROM is "built-in" computer memory containing data that normally can only be read, not written to. ROM contains the programming that allows your computer to be "booted up" or regenerated each time you turn it on. Unlike a computer's random access memory (RAM), the data in ROM is not lost when the computer power is turned off. The ROM is sustained by a small long-life battery in your computer.
Answer:
The function is as follows:
def divisible_by(listi, n):
mylist = []
for i in listi:
if i%n == 0:
mylist.append(i)
return mylist
pass
Explanation:
This defines the function
def divisible_by(listi, n):
This creates an empty list
mylist = []
This iterates through the list
for i in listi:
This checks if the elements of the list is divisible by n
if i%n == 0:
If yes, the number is appended to the list
mylist.append(i)
This returns the list
return mylist
pass

Answer:
Let f be a function
a) f(n) = n²
b) f(n) = n/2
c) f(n) = 0
Explanation:
a) f(n) = n²
This function is one-to-one function because the square of two different or distinct natural numbers cannot be equal.
Let a and b are two elements both belong to N i.e. a ∈ N and b ∈ N. Then:
f(a) = f(b) ⇒ a² = b² ⇒ a = b
The function f(n)= n² is not an onto function because not every natural number is a square of a natural number. This means that there is no other natural number that can be squared to result in that natural number. For example 2 is a natural numbers but not a perfect square and also 24 is a natural number but not a perfect square.
b) f(n) = n/2
The above function example is an onto function because every natural number, let’s say n is a natural number that belongs to N, is the image of 2n. For example:
f(2n) = [2n/2] = n
The above function is not one-to-one function because there are certain different natural numbers that have the same value or image. For example:
When the value of n=1, then
n/2 = [1/2] = [0.5] = 1
When the value of n=2 then
n/2 = [2/2] = [1] = 1
c) f(n) = 0
The above function is neither one-to-one nor onto. In order to depict that a function is not one-to-one there should be two elements in N having same image and the above example is not one to one because every integer has the same image. The above function example is also not an onto function because every positive integer is not an image of any natural number.
