Then answer you seek is 133.
Answer:
Step-by-step explanation:
levels of organic pollutants with 99.7% accuracy
levels of volatile solvents with 99.92% accuracy
levels of chlorinated compounds with 89.7% accuracy
samples:
60% contaminated with organic pollutants
27% contaminated with volatile solvents
13% contaminated with traces of chlorinated compounds
a) probability that the test will signal?
P = 0.997*0.6 + 0.9992*0.27 + 0.897*0.13 = 0.5982
+ 0.269784 + 0.11661 = 0.984594 = 98.45%
b) If the test signals, the probability that chlorinated compounds are present?
P = 0.897*0.13/0.984594 = 0.11661/0.984594 = 0.1184346035 = 11.84%
Answer:
We need the chart.
Step-by-step explanation:
Answer: 4
Explaination: In order to fine the volume of a cube typically the formula is S to the power of three or the number multiplied 3 times ex 6x6x6
Since the volume in 64 you can plug that into you can take 64 divide that in half so by 2
64 divided by 2 and you will get 32 after that you can divide by 2 again since you need to do it 3 times Becuase it’s the opposite of multiplying. Then you will get 16. The square root of 16 is 4 is the side of a cube is 4 :). This was a very complicated way of doing it but it you know the formula for volume of a cube which is S to the power of three you can multiply a number 3 times and see if it equals 64.
