Use the image to answer the question.
A scatterplot on a coordinate plane of quadrant 1 is titled as Snow Accumulation in Inches per Hour.
"The plane shows the x-axis, labeled as Hours, ranging from 0 to 6 in increments of 1, and the y-axis, labeled as Snow Accumulation in Inches, ranging from 0 to 12 in increments of 1. Six points are plotted and an upward line is drawn through or near the points. The line passes approximately through the following unlabeled points: left parenthesis 0 comma 0 right parenthesis, left parenthesis 1 comma 1.5 right parenthesis, left parenthesis 2 comma 4 right parenthesis, left parenthesis 3 comma 5 right parenthesis, left parenthesis 4 comma 7.5 right parenthesis, and left parenthesis 6 comma 10 right parenthesis."
A meteorologist collected data on a recent snowfall. The meteorologist graphed the data and found the equation of the trend line to be y=1.7x+0.1
. If the snowfall continues at this pace, use the equation to predict the number of inches of snow after 10 hours. Round to the nearest tenth.
(1 point)
After 10 hours, the snowfall would be
inches.
1 answer
To predict the number of inches of snow after 10 hours using the equation of the trend line \( y = 1.7x + 0.1 \), we need to substitute \( x = 10 \) into the equation.
\[ y = 1.7(10) + 0.1 \] \[ y = 17 + 0.1 \] \[ y = 17.1 \]
After rounding to the nearest tenth, the prediction is:
After 10 hours, the snowfall would be 17.1 inches.
