Pls help I’ll brainlest ASAP and add extra points

Answer:

1. A

2. B

3. A

4. his conclusion should be the juice made group A do less stacks than B

5. give the juice do group B and see if the result changes

Step-by-step explanation:

P.S. = the group A underperfomance actually had nothing to do with the juice, it was because Homer was in this group, lol (JK)

Explanation (2)

•The independent variable is the variable or the thing that the scientist/creator changes.

•the dependent variable is what we measure at the end and it depends on the independent.

•Controlled group/variable is the thing that should be constant in order to have an accurate results and it never changes even if anything changes in the experiment.

Answers:

1. Controlled: Number of stacks of paper

Amount of time

Amount of juice

Number of workers

2. Independent: Amount of juice given to workers

3. Dependent: Number of stacks at the end

•Explanation that helps with your conclution: The juice has nothing to do with how much stacks the workers finish. It depends on how each worker is handled to do their work even when on pressure, also. The juice may be a distraction to the workers because they drink it while working so they're consuming their energy without the help of the juice. Lastly, maybe some of the workers didn't drink the same amount of juice while working on finishing the stacks.

4. CONCLUSION: Group B had much higher results than Group A in 24% Even though they didn't drink the juice. Shows that workers do their job more efficiently and faster when their not distracted while working.

5. (a) Smith should make sure that the 50 workers drink the same amount of juice before they start their work and also make sure that both groups start doing their task at the same time and finish at the same time, for accurate changes.

(b) As Felipe said: try to give the juice to group B and see the result change.

(c) Do the experiment many times to see how long does the juice keep the workers productive while working, by the results change.

Which statement compares the two numbers correctly?

7 x 10 + 3 x 1 + 3 x 0.1 + 8 x 0.01 + 5 x 0.001 ________ 73.293

7 x 10 + 3 x 1 + 3 x 0.1 + 8 x 0.01 + 5 x 0.001 < 73.293
7 x 10 + 3 x 1 + 3 x 0.1 + 8 x 0.01 + 5 x 0.001 = 73.293
73.293 > 7 x 10 + 3 x 1 + 3 x 0.1 + 8 x 0.01 + 5 x 0.001
