a
b
c
Step-by-step explanation:
The number of vehicles available is 
The number of vans is k = 5
The number of cars is n = 13
Generally P(E) is mathematically represented as
=> 
=>
Generally P(F| E) means the probability that the second vehicle assigned is a van given that the first one selected is a van this mathematically calculated as
Generally 
is also mathematically represented as
=> 
=> 
=>
4 times 2 is 8 and 8-4 is 4 so 4 X10 is 40 plus 8 is 48

Step-by-step explanation:
Answer:
The correct answer is A) x^6y^8
Step-by-step explanation:
The easiest way to find this is to first square the second term.
(-x^2y^3)^2 = (x^4y^6)
Now we multiply that by the first parenthesis.
(x^2y^2)(x^4y^6) = x^6y^8
1) 2x = +/- 4 so x = +/- 2
2) x-3 = 7 OR x - 3 = -7
so x = 10 or x = -4
3)2x + 5 = 21 OR 2x + 5 = -21
so x = 8 or x = -13
4) x + 4 = 6 OR x + 4 = -6
so x = 2 or x = -10
5) x + 2 = -(2x+4) OR x + 2 = 2x + 4
x = -2 or x = -6
6) x + 7 = 0
x = -7
7) you forgot the equal sign somewhere in this problem
