When it's x²/a² - y²/b²=1 it's the one with zeros on the x axis, at x=±a, y=0.
Here the zeros are at (±5,0) so that's the first page, second graph.
Answer:
16
Step-by-step explanation:
Turn 10% into a decimal, so 0.1
160 x 0.1 = 16
I made a probability tree. Pls. see attachment.
Based on the probability tree I made, below are the probabilities
Probability of a student accepted at both Dartmouth and Harvard is:
50% x 40% = 20%
Probability of a student accepted at Dartmouth but not Harvard is:
50% x 60% = 30%
Probability of a student not accepted at Dartmouth but accepted in Harvard is:
50% x 20% = 10%
Probability of a student not accepted in both schools is:
50% x 80% = 40%
As you can see, these probabilities total 100%
I hope this help you with what you need
