Answer:
19 days
Step-by-step explanation:
305 - 115 = 190
190 ÷ 10 = 19
Answer:
<u>The probability that carbon emissions from the factory are within the permissible level and the test predicts the opposite to be true is 19.338% (Rounding to the next thousandth place)</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Probability that carbon emissions from the company’s factory exceed the permissible level = 35% = 0.35
Accuracy of the test of emissions level = 85% = 0.85
2. The probability that carbon emissions from the factory are within the permissible level and the test predicts the opposite to be true is?
These two events, carbon emissions from the company’s factory and the accuracy of the test are independent events, therefore:
Probability that carbon emissions from the factory are within the permissible level = 1 - 0.35 = 0.65
Probability that the test predicts the opposite to be true = 0..35 * 0.85 = 0.2975 (The opposite is that the carbon emissions from the company exceed the permissible level)
Probability that carbon emissions from the factory are within the permissible level and the test predicts the opposite to be true is:
0.65 * 0.2975 = 0.193375
<u>The probability that carbon emissions from the factory are within the permissible level and the test predicts the opposite to be true is 19.338% (Rounding to the next thousandth place)</u>
You need to know that:
1 ounce = 28.35 grams
So, 1 tube contains
3.0 oz × 28.35 = 85.05g total mass
Mass of Benzyl salicylate =
2.40/100 = Percentage of Benzyl salicylate (in numerical value)
= 0.024
0.024 × 84 = Mass of Benzyl Salicylate
=2.016g
If one tube contains
2.016g × 425 tubes
=856.8g
Then,
Converting into kg by (dividing by 1000)
=856.8 ÷ 1000
= 0.8568 grams
= 0.857g (3sf)
