To calculate the total amount of rainfall recorded by Chase based on the line plot provided, we will add up the individual contributions from each measurement represented by the dots.
-
Zero inches: 1 dot (0 inches)
- Contribution: \( 1 \times 0 = 0 \) inches
-
Three-eighths inch: 2 dots (0.375 inches)
- Contribution: \( 2 \times \frac{3}{8} = \frac{6}{8} = \frac{3}{4} \) inches
-
Four-eighths inch: 1 dot (0.5 inches)
- Contribution: \( 1 \times \frac{4}{8} = \frac{4}{8} = \frac{1}{2} \) inches
-
Five-eighths inch: 1 dot (0.625 inches)
- Contribution: \( 1 \times \frac{5}{8} = \frac{5}{8} \) inches
-
Seven-eighths inch: 1 dot (0.875 inches)
- Contribution: \( 1 \times \frac{7}{8} = \frac{7}{8} \) inches
Next, we add all these contributions together:
\[ 0 + \frac{3}{4} + \frac{1}{2} + \frac{5}{8} + \frac{7}{8} \]
To add these fractions, we need a common denominator. The least common multiple of 4, 2, 8, and 8 is 8. We will convert each fraction:
- \( \frac{3}{4} = \frac{6}{8} \)
- \( \frac{1}{2} = \frac{4}{8} \)
- \( \frac{5}{8} = \frac{5}{8} \)
- \( \frac{7}{8} = \frac{7}{8} \)
Now we can add them together:
\[ \frac{6}{8} + \frac{4}{8} + \frac{5}{8} + \frac{7}{8} = \frac{6 + 4 + 5 + 7}{8} = \frac{22}{8} = \frac{11}{4} \]
Converting \( \frac{11}{4} \) to a mixed number gives:
\[ \frac{11}{4} = 2 \frac{3}{4} \]
Thus, the total amount of rainfall recorded is \( 2 \frac{3}{4} \) inches.
However, the answer choices provided don't seem to include \( 2 \frac{3}{4} \). Considering typographical variations such as fractions or whole number representations, it is important to ensure careful alignment with the choices laid out.
If it's a case of 2 6/8 inches as listed, it stands verified \( \frac{6}{8} = \frac{3}{4} \) hence the best closest interpretation leads to:
Final Answer: 2 6/8 inches
It appears necessary to align to the closest selectable information in relation to conjectured display and ensure understanding amidst misrepresentations. Please continue to evaluate ongoing determinants and permutations should any explanatory direction prompt new findings.
