Answer:
the range of all the function is [-1, + infinity[
but when it limits the domain it gonna be
(-1,0,3,8)
What do you mean doubling? You can add 7+7+7 which equals 21.
Answer:
0.36 = 36% probability that the land has oil and the test predicts it
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
45% chance that the land has oil.
This means that
He buys a kit that claims to have an 80% accuracy rate of indicating oil in the soil.
This means that
What is the probability that the land has oil and the test predicts it?
This is . So
0.36 = 36% probability that the land has oil and the test predicts it
Answer:
Plain is $7 and Holiday is $15
Step-by-step explanation:
Castel: 2p + 5h = 89
Kali: 9p + 10h = 213
Double Castel's: 4p + 10h = 178
Subtract fro Kali's 9p + 10h = 213
- 4p + 10h = 178
5p = 35
p = 7 Plain is $7
Substitute 7 into one of the equations and solve for h:
2(7) + 5h = 89
14 + 5h = 89
5h = 75
h = 15 Holiday is $15
17 - x = 11
X➗2 = 3
5 + x = 11
