Answer:
B.2 1/41
Step-by-step explanation:
In a perfect square trinomial of the form ax+bx+c where a, b and c are constants, the value of (b/2)²=ac
In the provided equation the value of a=1, b=-3 c=?
Therefore, (-3/2)²=c since a-the coefficient of x²=1 and 1×c=c
c=2.25= 2 1/4
Thus the trinomial x² - 3x + 2 1/4 is a perfect square.
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
