The table shows the height of the tree that Margo planted over an 11-month period.

\begin{tabular}{|c|c|}
\hline \multicolumn{2}{|c|}{Growth of Margo's Tree} \\
\hline Month & Height of Tree (t) \\
\hline 1 & 1.4 \\
\hline 3 & 1.5 \\
\hline 6 & 2.1 \\
\hline 7 & 2.7 \\
\hline 9 & 3.0 \\
\hline 11 & 1.8 \\
\hline
\end{tabular}

Which statement can be supported by the information in the table?

A. The tree increased in height each month during the entire 11-month period.
B. The tree decreased in height each month during the entire 11-month period.
C. The tree increased in height each month until the time period between month 9 and month 11.
D. The tree decreased in height each month until the time period between month 9 and month 11.


Sagot :

Let's carefully examine the height of the tree over the given time period and analyze the statements provided.

The heights of the tree at different months are as follows:

- Month 1: 1.4
- Month 3: 1.5
- Month 6: 2.1
- Month 9: 2.7
- Month 11: 1.8

First, let's determine if the tree consistently increased in height throughout the entire 11-month period.

1. Check if the tree increased between each observation:
- From Month 1 (1.4) to Month 3 (1.5): 1.4 < 1.5 (True)
- From Month 3 (1.5) to Month 6 (2.1): 1.5 < 2.1 (True)
- From Month 6 (2.1) to Month 9 (2.7): 2.1 < 2.7 (True)
- From Month 9 (2.7) to Month 11 (1.8): 2.7 < 1.8 (False)

Since the height decreased from Month 9 to Month 11, the statement "The tree increased in height each month during the entire 11-month period" is not supported.

Next, let's determine if the tree consistently decreased in height throughout the entire 11-month period.

2. Check if the tree decreased between each observation:
- From Month 1 (1.4) to Month 3 (1.5): 1.4 > 1.5 (False)
- From Month 3 (1.5) to Month 6 (2.1): 1.5 > 2.1 (False)
- From Month 6 (2.1) to Month 9 (2.7): 2.1 > 2.7 (False)
- From Month 9 (2.7) to Month 11 (1.8): 2.7 > 1.8 (True)

Since the height did not consistently decrease between each observation, the statement "The tree decreased in height each month during the entire 11-month period" is also not supported.

Now, let's determine if the tree increased in height each month until the period between Month 9 and Month 11.

3. Check if the tree increased in height from Month 1 to Month 9:
- From Month 1 (1.4) to Month 3 (1.5): 1.4 < 1.5 (True)
- From Month 3 (1.5) to Month 6 (2.1): 1.5 < 2.1 (True)
- From Month 6 (2.1) to Month 9 (2.7): 2.1 < 2.7 (True)

Since the tree increased in height from Month 1 to Month 9 and then decreased from Month 9 to Month 11, the statement "The tree increased in height each month until the time period between month 9 and month 11" is supported.

Lastly, let's determine if the tree decreased in height each month until the period between Month 9 and Month 11.

4. Check if the tree decreased in height from Month 1 to Month 9:
- From Month 1 (1.4) to Month 3 (1.5): 1.4 > 1.5 (False)
- From Month 3 (1.5) to Month 6 (2.1): 1.5 > 2.1 (False)
- From Month 6 (2.1) to Month 9 (2.7): 2.1 > 2.7 (False)

Since the heights did not consistently decrease between Month 1 and Month 9, the statement "The tree decreased in height each month until the time period between month 9 and month 11" is not supported.

In conclusion, the statement that is supported by the information in the table is:
"The tree increased in height each month until the time period between month 9 and month 11."
