Answer:
y=(x^2 -2x-3)/3
Step-by-step explanation:
f(x)= √3x+4 -1
x=√3y+4 -1
(x+1)^2=(√3y+4)^2
3y+4=x^2 +2x+1
3y=x^2 +2x-3
y=(x^2 +2x-3)/3
Answer:
x = 6
Step-by-step explanation:
The probability that this archer hits her first shot is given by t the probability of being windy and that she hits the shot added to the probability of not being windy and that she hits the shot:
If the probability that she hits the target on her first shot is 0.x1, the value of x is:
First pear Second pear probability
green (3/7)---------green (2/6) (3/7)*(2/6) = 1/7
---------red (4/6) (3/7) *(4/6) = 2/7
red (4/7)-------------green (3/6) (4/7)*(3/6) = 2/7
-------------red (3/6) (4/7)*(3/6) = 2/7
-------------------------
1/7 + 2/7 + 2/7 + 2/7 = 1
The probailities that two are green are: 1/7
The probabilities that one is green and the other is red are:2 /7 + 2/7 = 4/7
The probabilities that two are red are: 2/7
I think the best answer is 3 to 9 but thats not a answer so 3 to 6
