A. 5 digit code with digits from 0-9 with no repetition.
Choices for 1st digit=10, and choices for successive digits are 9,8,7,6.
Probability of guessing it correctly on first try is
1/(10*9*8*7*6) = 1/30240
B. If zero is not in the combinations, then the domain of digits is 1-9, or 9 choices. Digits can repeat means every digit in the code has 9 choices.
Number of arrangements = 9^5 = 59049
Probability of guessing at first try = 1/59049
Y = -1/3x + b
then plug it in
-4 = (-1/3 x 6) + b. (6 times -1 divided by 3)
-4 = -2 + b. (move -2 to other side)
b = -2. (now put em all together)
y = -1/3x -2
Answer:
Loaves of bread: b can't be a negative value, then the first table doesn't include viable solutions.
The number of loaves of bread must be a whole number, then the second table doesn't include viable solutions.
c=3.5b
if b=0→c=3.5(0)→c=0
If b=3→c=3.5(3)→c=10.5
If b=6→c=3.5(6)→c=21
If b=9→c=3.5(9)→c=31.5
The third table includes viable solutions
Answer: 0.074
Step-by-step explanation:
It’s simple actually! Just do 0.72/9.72 and it gives you 0.074.
Hope this helps!
