Answer:
Correct option: A -> 10/91
Step-by-step explanation:
If the password has only one number, it has three characters.
So first we can do a combination of 4 choose 3, as the characters and numbers can be at any position, then we multiply by the probability of each space having a character or number:
Combination of 4 choose 3: 4!/3! = 4
First character: 6 possibilities over a total of 16: 6/16 = 3/8
Second character: 5 possibilities over a total of 15: 5/15 = 1/3
Third character: 4 possibilities over a total of 14: 4/14 = 2/7
First number: 10 possibilities over a total of 13: 10/13
Probability: 4 * (3/8) * (1/3) * (2/7) * (10/13) = (2*5)/(7*13) = 10/91
Correct option: A
You meant "find the constant of proportionality"
Given <span>y=2 when x= -1/2, and looking for a formula such as y = k*x,
substitute the given value (2) for y and the given value (-1/2) for x:
2 = k * (-1/2). Solve this for k. Then write out the general formula y = k * x, and let x= -0.3.</span>

1. The first step is Distribution, a = 10a - 14. You can determine this by multiplying 2 into (5a - 7). 2*5a =10a, while 2*- 7 = - 14. Resulting in, a = 10a - 14.
2 . Now, subtract 10a on both sides, meaning 10a - 10a and a - 10a. The equation simplified is - 9a = - 14.
3. Divide by - 9 on both sides. The solution to the equation is a = 14/9
