X^2 + y^2 = 5
y = 2x
The second equation is solved for y, so substitute it in the first equation.
x^2 + (2x)^2 = 5
x^2 + 4x^2 = 5
5x^2 = 5
x^2 = 1
x^2 - 1 = 0
(x + 1)(x - 1) = 0
x = -1 or x = 1
Now substitute both values of x in the second equation and solve for y.
y = 2x
For x = -1
y = 2(-1)
y = -2
For x = 1
y = 2(1)
y = 2
Solution: (-1, -2), (1, 2)

Answer:
0.24
Step-by-step explanation:
From the information given:
Let's have a schematic view of a tree diagram
A
P(Santa Cruz) P(Isabella)
= 13/15 = 2/15
P(Success | Santa Cruz) = 0.09 P(Success | Isabella) = x
We are told that many have tried to locate the giant turtle, but 89% of them have failed.
This means the probability of success is:
P(success) = 1 - 0.89 = 0.11
We need to find P(Success | Isabella),
Suppose P(Success | Isabella) be x as shown above,
Then:
P (Success) = P(Santa) P((Success | Santa Cruz) + P(Isabella) P(Success | Isabella)
make x the subject of the formula:
x = 0.032/0.133
x = 0.24
