Answer:
i believe it’s graph A
Step-by-step explanation:
Okay, so let's find the actual failure rate first. 6/1000 times 100 (to give over a 100%) equals to 0.6. The actual failure rate is 0.6%. The theoretical probability is 0.2% 0.6-0.2=0.4. The difference is 0.4%.
Hope that helped!
Solutions
⇒9/12
1) To see if 9/12 is in simplest form you have to find 9 and 12's GCF.
The GCF of 9 and 12 is 3
2) Divide by the GCF
9 ÷ 3 = 3
12 ÷ 3= 4
3/4 is answer
8 x 64
=64 x 2 x 4
=128 x 2 x 2
=256 x 2
=512
