Answer:
1. She ate 4 times more pieces of candy on Tuesday than on Monday.
2. Brice earned $63
3. 48 people
4. Erin collected 4 times more coins than Luke.
5. They sold 96 pizzas.
Step-by-step explanation:
1. 24/6 = 4
2. 9 x 7 = 63
3. 12 x 4 = 48
4. 44/ 11 = 4
5. 32/8 = 4
6. 8 x 12 = 96
Answer:
36/(36+26+14+16)
probability is given by event/total possible outcomes
Slope is -3
y intercept is -6
Answer:
The probability is
Step-by-step explanation:
If she has n distinct password candidates and only one of which will successfully log her into a secure system, the probability that her first first successful login will be on her k-th try is:
If k=1
Because, in her first try she has n possibles options and just one give her a successful login.
If k=2
Because, in her first try she has n possibles options and n-1 that are not correct, then, she has n-1 possibles options and 1 of that give her a successful login.
If k=3
Because, in her first try she has n possibles options and n-1 that are not correct, then, she has n-1 possibles options and n-2 that are not correct and after that, she has n-2 possibles options and 1 give her a successful login.
Finally, no matter what is the value of k, the probability that her first successful login will be (exactly) on her k-th try is 1/n
