= <u>62.32%</u>
<span>Say the code only needed to be one number long. Going from 0-9, there are ten digits. Therefore, there are ten unique codes.
Now say the code has to be two numbers long. There are ten possibilities
for the first digit, 0-9. But the second digit only has nine
possibilities, since each number has to be different. (The first number
might be 0, so the second can only go from 1-9) For each of the first
ten possibilities, there are nine possibilities for the second. We
multiply those two numbers together, 10 * 9, and we get 90.
Now we just extend the logic. The third number only has eight
possibilities, while the fourth number only has seven. 10 * 9 * 8 * 7 =
5040 possible codes. I hope this helped! has a great day! :)</span>
Answer:
D
Step-by-step explanation:
y=2x²+2x+1.... i
y=2x+3......... ii
Equating i and ii,
2x²+2x+1=2x+3
2x²+1-3=0
2x²-2=0
x²-1=0
x=1 or -1.
From ii, if x=1,y=5
If x=-1, y=1.
The points are (-1,1) and (1,5)
