Answer:
39/37 and 6/5
Step-by-step explanation:
To start, let's assume that 9-8x is positive (we will do this to get rid of the absolute value, but then check later). We get 9(9 - 8x) = 2x + 3, or 81 - 72x = 2x + 3, so 74x = 78 and x = 39/37. If we assume 9-8x is negative, the |9-8x| will turn into 8x-9, so we get 9(8x - 9) = 2x + 3, or 72x - 81 = 2x + 3 , so 70x = 84 and x = 6/5. If we plug the values back in, 9-8(39/37) needs to be positive, which works, and 9-8(6/5) needs to be negative, and this works, so the answers are 39/37 and 6/5.
Answer:
27
Step-by-step explanation:
In this case we associate in total value from 225 to 100%, and they tell us that foreign currencies represent 88%, therefore, in quantity this would be:
225 * 88/100
198
The rest of the coins would then refer to the other coins I collect, which would be:
225 - 198 = 27
That is, 27 coins are the remaining coins.
In a randomized block design, it is expected treatments are randomly assigned within each block.
<h3>What does a randomized block design imply?</h3>
- Subjects are divided into blocks based on a specific features such as age, gender, education, etc.
- Within each block subjects that receive treatment and does who do not are randomly assigned.
- The treatment in all blocks is the same. For example, if the purpose is to study the effect of medicine all treatment subjects should receive the same medicine and dose.
<h3>What is the purpose of this design?</h3>
The purpose is to minimize the effect of certain factors such as age.
Based on the above, it is expected in this experiment the treatment is randomly assigned to a specific number of subjects within each block.
