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 = m
x + b
.
y = 6
x − 7
Hope this helped!
Answer:(3,0)
Explanation:To find the x substitute 0 in for y,7x+3*0=21.Next,multiply 3 and 0,and that gives you 0,7x+0=21 .After you do that you need remove 0 because when you add and subtract zero the quantity doesn’t change,7x=21.Lastly,divid both sides of the equation by 7,and that gives you x=3.
