The probability is:
0.71
Let A denote the event it is defective
and B denote the event that it is not made by Ratten company.
Lens Defective Not Defective Total .
Greens 5% 55% 60% .
Parsons 10% 5% 15% .
Ratten 6% 19% 25% .
Total 21% 79% 100%
P(A)=0.21
( Since 21/100=0.21 )
P(A∩B)= 15%
( Since, 5%+10%=15%
and 15%/100%=0.15)
Hence, we are asked to find P(B|A)
We know that:
The answer is:
0.71
swim 36 laps an hour. Determine the
percent change
Answer:
D
Step-by-step explanation:
If the percent change is 30 to 36 you can already see that it is an increase
here is the work
36 - 30
30
x 100% = 20%
Answer:
20% increase, which corresponds to the light
Step-by-step explanation:
(y - x)/x * 100
(36 - 30)/30 * 100
(6 * 100)/30
600/30
20% increase
Answer:
The coefficient is 2
B. 48 sq meters
C. 24 sq meters
D. 7 sq meters
Answer: 69
Step-by-step explanation: Percent multiplied by the total number of students: 8/100 x 75 = 600/100. (remember it is 8/100 because it’s 8%.)
Then you simplify which will then get you 6.
Afterwards you need to subtract those 6 students from the group of 75. 75-6=69. So, 69 students.
