In order to factor a value out of an expression we must divide each term by this value, so ((1/3)*y - 3/2)/-(1/3) = (-1/3)*(-y + 9/2)
I don't know exactly what a fraction box is sorry
Answer:
I don't know 1
2. 3/4
3. y= 1000(0.75)^x
Step-by-step explanation:
The probability can be modeled using the following formula:
wherein X follows the density
Now for k = 3 we get:
The probability we are looking for is 0.15.
