Answer:
X = {0, 1, 2, 3, 4}
Step-by-step explanation:
If X is the number of nonzero digits in a 4-digit PIN with no restriction on the digits, the pin can have up to 4 nonzero digits.
Let's see some examples:
If the PIN is 0000 then X = 4
If the PIN is 2045 then X = 3
If the PIN is 7546 then X = 0
From the previous examples, we can see that the possible values for X are 0, 1, 2, 3, 4.
Thus X = {0, 1, 2, 3, 4}
Step-by-step explanation:
Answer 3
multiply 4 by -20
1/4×-20
= -20/-20
= 1 answer
I believe it would be 12/18 so that would be 2/3 and 0.6 in decimal form
I do not answer I mean College and I passed it
