Answer:
He did not control for lurking variables and their impacts on the results of his experiment. Amount of sunlight and water received are two outside variables(or confounding variables) that may impact the growth of his plants and influence the results. He needs to apply the same amount of sunlight and water to each plant within a different planting soil in order to rule out the influence of those two variables and test the sole effect of the soil brand on the plant growth. Otherwise, it would be hard to determine whether his plant growth was because of the soil brand or the different amounts of sunlight and water received
Answer:
4
Step-by-step explanation:
- Add up your data. 3+13+11+5=32
- Divide the sum by the number of data you have. In your case you would divide 32/4/
- This will give you 8, which is your mean. Now, subtract 8 from each value and put the difference to its absolute value.
- Now, add up each of these values (5+5+3+3=16), then divide by 4. This will give you an answer of 4.
Hope this helps! Have a great day :)
So first you would have to work with the y's since they are consecutive angles.Consecutive angles would add up to 180 so the problem would be
5(y+11)^0+4y-10=180 then simplify
10+4y-10=180
4y=180
y=45
Then plug in the y for the top problem and the add the answer to the x problem and set them to 180 because they are also a linear pair and you should get your answer
I got x=34
Either the first or third are positive
