Question

The scatterplot shows the weight, in ounces, of the fruit on a certain truffle tree from days $55$ to $85$ after flowering. According to the line of best fit in the scatterplot, which of the following is the closest approximation of the number of days after flowering of a truffle fruit that weighs $5.75$ ounces?

• A. $63$
• B. $65$
• C. $55$
• D. $81$

Answer 1

The correct option is C $55$

Weight is shown on the vertical axis of the graph, given in ounces. Make your own mark indicating $5.75$ on this axis; then draw a horizontal line from that mark to the line of best fit. Once you hit it, draw a vertical line straight down to the horizontal axis. It should hit between $75$ and $80$ days, slightly closer to the mark for $75$.
Which gets us to closest conclusion to $55$ days.
Option C is correct.
