Answer:
C
Step-by-step explanation:
The inequality says greater than or equal to 8, which means the first two are automatically ruled out because they are both less than/equal to.
Then look at C and D, D starts at 3 and C starts at 8 so the answer should be C
Answer:
No solutions
Step-by-step explanation:
4(2x-3)=2(4x-6)
Same components are present on both sides of equal sign, therefore NO SOLUTIONS are possible.
Answer:
0.2752512
Step-by-step explanation:
The formula you are looking for is the binomial probability:
n!
P (X) = ------------ * (P)^X * (q)^n - X
(n- X)! X!
For your particular problem:
n=7
X=2
q = 1-p = .8
7!/(5!*2!)*(.2)^2*(.8)^5 = 0.2752512
Hope this helps, have a nice day/night! :D
