Answer:
The probability of selecting randomly 6 packets such that the first 4 contain cocaine and 2 not is 0.3522.
Step-by-step explanation:
Probabilities of selecting 4 packets with the ilegal substance:
= 
Combinassions possible= 1365
Probabilities of selecting 2 packets with white powder:
= 
Combinations possible= 10
Probabilities of selecting 6 packets from the totality of them:
= 
Combinations possible= 38760
The probability of picking 4 with the substance and 2 with only white powder is:
= 0.3522

Hi Grant.
(3x + 5) + (2x - 9) is what we'll start with. Considering we cannot combine variables with numbers, we can only combine like-terms.
3x + 2x; 5 - 9; we result with: 5x - 4
Now, we are left with (5x - 4) - (4x + 3)
Remember to distribute the negative sign to everything to the right.
(5x - 4) - 4x - 3. We are now able to simplify and solve for our answer.
5x - 4x; -4 - 3; we result with x - 7.
Your answer is A.) x - 7.
I hope this helps!
Answer:

Answer:
4
Step-by-step explanation:
Based on the information you have given me, p = 1/3.
All we need to do is substitute that value into the expression:
12p = 12(1/3) = 4
Answer:
1.5 - it represents the time in seconds where the ball is highest
Step-by-step explanation:
There are 2 methods of approaching this.
The first method involves graphing, simply place into a graphing calculator and view the vertex. The horizontal line coming down from the vertex is the axis of symmetry (it splits the parabola in half).
The second method is finding the axis of symmetry (vertex) algebraically.
-b/2a is the equation used to find the x term of the vertex, and if we were to substitute our values in, we'd get -48/-32, giving us 1.5
