=56 m²
Answer:
correct
Step-by-step explanation:
Answer:
C) S = {F, PF, PPF, PPP}
Step-by-step explanation:
For this case, we know that a person is trying to gain access to a bank vault and needs to go through 3 security doors, and we know that if the person does not pass a door, then he/she has no other attempts. We denote P= Successful pass , F= Failed pass
And we are interested on the sample space, we need to remember that the sample is the set with all the possible values for an experiment.
For this case the person can fail at the 1,2 or 3 try
For the case that fails at the 1 try we have F
For the case that fails at the 2 try we have PF
For the case that fails at the 3 try we have PPF
And the last option is that the person not fails at any try and we have PPP
So then the sample space would be given by:
C) S = {F, PF, PPF, PPP}
Answer:
1 or -9, depends on the problem, see below.
Step-by-step explanation:
-11--7+5
Two negatives make a positive so our new equation is:
-11+7+5
-11+7 is -4, so:
-4+5
And this leaves us with:
1
But I saw there was a parentheses, was it misplaced or was one not added? If one was not ended to the end, then the answer would be different.
(-11)-((-7)+5)
-7+5 is negative 2, so:
-11-(-2)
Once again, two negatives make a positive, so our new equation would be:
-11+2
Which gets us:
-9
