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
Taking point (0,-2) of graph one and replacing in the equation;
2x+3y=6
2(0)+3(-2)=6
-6=6
So graph isn't the required graph.
Taking point (0,2) of graph 2;
2x+3y=6
2(0)+3(2)=6
6=6
So, graph 2 is the required graph.
Answer:
60 and
x=4
Step-by-step explanation:
Answer:
$390+0.07s=$544+0.05s Subtract $390 from each side.
0.07s=$154+0.05s Subtract 0.05s from each side.
0.02s=$154 Divide each side by 0.02.
s=$7700 Both plans pay the same when sales=$7700
