Answer:

0.24

Step-by-step explanation:

From the information given:

Let's have a schematic view of a tree diagram

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)

$0.11 = \dfrac{13}{15}(0.09)+ \dfrac{2}{15}(x)$

$0.11 - \dfrac{13}{15}(0.09)= \dfrac{2}{15}(x)$

$0.032= 0.133(x)$

make x the subject of the formula:

x = 0.032/0.133

x = 0.24

Answer:

Below

Step-by-step explanation:

5^n = 0.2

First write the number in exponential form with the base of 5 :

5^n = 5^-1

Because the bases are the same, we can set the exponents as equal :

x = -1
