Answer:
1. 70%
2. Yes
Step-by-step explanation:
1. there are 7 that are over 48, and 10 total. so, 7/10, or 70% would be our answer.
2. 70% is greater than 65%, so yes. he did it better than them.
1. The proportion of the reactions that were above the 48 grams threshold was 70 percentage.
2. The engineer was able to increase the proportion of useful product when compared to the other chemists.
A proportion is an equation in which two ratios are set equal to each other.
Percentage is a number or ratio that can be expressed as a fraction of 100.
It is given that a chemical engineer is trying to increase the amount of the useful product in a reaction
1. Out of the 10 results, 7 were above 48 grams.
Hence the proportion is
[tex]\frac{7}{10} \times 100 = 70\%[/tex]
2. Since the other chemists typically get 65 percentage of their proportion reactions to produce more than 48 grams, and the engineer got 70 percentage, she was able to increase the useful product when compared to the other chemists.
