Answer:
67,600 possible outcomes
Step-by-step explanation:
In total, it's a four digit password.
For the first digit, which is a letter, there are 26 possibilities. The same goes for the second digit, so first multiply 26 x 26 (because that's the number of possibilities for the first two digits alone).
! if the letters have to be different then it would be 26 x 25 because there's one less letter for the second digit.
Next, 2 one digit numbers. There are 10 individual digits: 0,1,2,3,4,5,6,7,8,9, so after 26 x 26 x 10 x 10 for the total number of possibilities. If the numbers have to be different (and the letters too) then it'd be 26 x 25 x 10 x 9
so 26 x 26 x 10 x 10 = 67,600
hope this helps!

Answer:
Step-by-step explanation:
y - 1 = 3(x + 4)
y - 1 = 3x + 12
y = 3x + 13
or
slope -3
y - 1 = -3(x + 4)
y - 1 = -3x - 12
y = -3x - 11
Answer:
Andrew takes a test for the disease that has an accuracy rate of 75%. What is the probability that Andrew has heart disease and the test accurately predicts it? The two events are independent, so you need to find the product of their probabilities: 0.9 × 0.75 = 0.675.
