Batch size = 280 purifiers
Defectives = 12 purifiers
Then,
P(defective) = defectives/batch size = 12/280 =3/70
As a percentage:
P(defective) = (3/70)*100 = 4.29%
If you would like to simplify 21/78, you can do this using the following step:
21/78 = 7/26
<span><span>The result is </span>7/26 <span>(this is not a mixed number, because mixed
numbers can be made from numbers greater than 1 and 7/26 is less than 1).</span></span>
Answer:
697cm³
Step-by-step explanation:
Volume = Base area* Height
= 17 x 10* 4.1
= 697cm³
She has n+3 books. Best guess. Not sure if you have answer choices. If so those would help.
Total number of cards = 13 + 5 + 2 = 20
Total number of yellow or green cards = 13 + 2 = 17
P(yellow or green) = 17/20
.
Answer: 17/20
