Answer:
0.097 is the probability that the entire batch will be rejected
Step-by-step explanation:
The total number of CDs = 6500
Number of defective CDs = 110
Number of good CDs = 6500-110 = 6390
Out of this batch, 6 are randomly selected, then the probability that the entire batch is rejected is
1 – [probability of accepting the entire batch]
1 – [6390/6500 * 6389/6499*6388/6498*6387/6497*6386/6496*6385/6495]
= 0.097
D. 300 it is. is there more?
Answer:
Elimination method
Step-by-step explanation:
We have a choice to eliminate the y or x:
I chose x
So now we double the second equation to make the co efficient of x the same:
6x-5y = -3
6x+4y = 24
Now we subtract both equations to eliminate the x's:
6x-5y = -3
- - -
6x+4y = 24
-9y = -27
y = 3
Now we substitute this value into either equation 1 or 2:
I chose 2
3x + 2(3) =12
Simplify:
3x + 6 =12
Subtract 6 from both sides:
3x + 6 -6 = 12 -6
Simplify:
3x = 6
Divide both sides by 3:
3x÷3 = 6÷3
Simplify:
x = 2
Answer:
y=1/3x+5 hope it helps you
