The best information we can use is the ratio of defectuosity, 2/150
Applying it to the size of the batch
N=3000*2/150 = 40
Answer: out of the batch of 3000 products, likely 40 products are defective, if the products are drawn from the same production run.
1.60
2. 70
3. 12 x 2, 8 x 3, 6 x 4
4. 18 x 2 , 12 x 3, 4 x 9
not sure for the first 2 but hope this helps
w = width
l = length
w = 1/3 length
l = 7 3/4
w = 1/3 * length
w = 1/3 ( 7 3/4)
change the mixed number to an improper fraction
7 3/4 = (4*7+3)/4 = 31/4
w = 1/3 ( 31/4) = 31/12
12 goes in to 31 2 times with 7 left over
w = 2 7 /12
Math is a important factor to law. You have to be able to know how many people , cars , and the amount of cash thats involved.
