A landowner wanted to determine the change in the water levels of his pond over time. First, he filled the pond to a water level of five feet. After two weeks, the water level was at 3.4 feet.
If the water level continues to change at that same rate, which of the following statements applies?
A.
For each week that passes, the water level increases by 1.6 feet.
B.
For each week that passes, the water level decreases by 0.8 foot.
C.
For each week that passes, the water level decreases by 1.6 feet.
D.
For each week that passes, the water level increases by 0.8 foot.

The change in the water level over the two-week period is 5 feet - 3.4 feet = 1.6 feet. This means that the water level decreases by 1.6 feet over a two-week period, which is equivalent to a decrease of 1.6/2 = 0.8 feet per week.
Therefore, the correct statement is:
B. For each week that passes, the water level decreases by 0.8 foot.
Patrick noticed a correlation between the number of hours he spends studying and his exam score. The table below shows his findings.
No. of Hours 1 2 3 4
Exam Score 82 87 92 97
What will he score on an exam if he doesn't spend any time studying?
A.
102
B.
72
C.

Based on the data provided in the table, we can observe that the exam score tends to increase as the number of hours studying increases. However, we cannot accurately determine what Patrick's exam score will be if he doesn't spend any time studying.
None of the given choices (A, B, C, or D) can be determined based on the information given.
