What are the answer choices ? Can you comment a picture of something so I can help you.
D. Y is negative and x is positive, so that means either B or D. Since y is negative, SUBTRACTING five would make a more negative number. So you want D.
Answer:
The experimental subjects are pine tree seedlings .
Step-by-step explanation:
The physical entity to which the treatment is assigned at random is known as experimental unit .
The same treatment cannot be received by two experimental units, they have to different treatments. The selection of experimental units plays an important role to determine the p-values in the statistical analysis. The experimental units are divided into different homogeneous groups called blocks.
From the question, the experimental subjects identified are pine tree seedlings.
We can start with the basics. What we know is that this entire trip took 6 hours. So the travelers were able to walk on the level, uphill, and downhill in a total of 6 hours.
A level mile takes 1/4 of an hour (15 minutes). An uphill mile takes 1/3 of an hour (20 minutes). A downhill mile takes 1/6 of an hour (10 minutes). So, to go and return over the same mile takes half an hour. This means that in 6 hours, they went 12 miles and came 12 miles back. So they went a total of 24 hours.
If the 12 miles had been all level, it would have taken approximately 3 hours. It the 12 miles had been all uphill, it would have taken approximately 4 hours. When reaching the peak, 3.5 hours would have been the approximate time it took them to reach the top since it is in between. <span />
