Answer:
be more pacific
Step-by-step explanation:
Step-by-step explanation:
3 more than twice n = 3+2n
3 more than twice n is atmost 50,
=> 3+2n <= 50 {(3+2n) is less than or equal to 50}
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
You bring the numerals on to the other side of the equation, therefore dividing 19 by 3 and 6.
3x + 6y = 19
3x + y = 19/6
x + y = 3.17/3
x + y = 1.1
Answer:
y = -3
Step-by-step explanation:
A horizontal line has all the same y values, but changing x values
y must equal -3 all the time if it goes through (3,-3)
y = -3
