The answer is 768 (you just multiply by 4)
Answer:
0.0816
Step-by-step explanation:
Given:
- Total number of students = 5000
- Number of students taking an online class = 1200
- Number of students prefer watching baseball to football = 1700
Let O = Students taking an online class
Let B = Students prefer watching baseball to football
Therefore,
P(O) = 1200/5000 = 0.24
P(B) = 1700/5000 = 0.34
If events O and B are independent,
⇒ P(O ∩ B) = P(O) · P(B)
= 0.24 × 0.34
= 0.0816

Let's look at an example
x^2 + 6x + 3 = 8
Take the "b" coefficient of the quadratic equation, which is 6 and divide in half and square it.
6/2 = 3
3^2 = 9
9 is what we need to be the constant on the left side not 3. We can add 6 to the 3 to make 9 ... but what ever you do to the left side must also be done to the right side to keep the equation the same. .
think of it in simple terms: 5 = 5
if you add 3 to the left but not the right it is not valid 5+3 does not equal 5 anymore
x^2 + 6x + 3 + 6 = 8 + 6
x^2 + 6x + 9 = 14
( x + 3)^2 = 14
