select the correct answer\na geologist gathered data about the total shoreline and maximum depth of several area lakes and organized the data into the table\n| total shoreline (miles) | 22 | 17 | 10 | 23 | 12 | 35 | 7 |\n| maximum depth (feet) | 101 | 85 | 59 | 113 | 64 | 158 | 33 |\nshe then used a graphing tool to display the data in a scatter - plot, with x representing the total miles of shoreline and y representing the maximum depth. she also used the graphing tool to find the equation of the line of best fit.\ny = 4.26x+10.908\nbased on the line of best fit, what is the approximate maximum depth of a lake that has 31 miles of shoreline?\na. 121 feet\nb. 132 feet\nc. 138 feet\nd. 143 feet
Answer
Explanation:
Step1: Identify the values
We are given the equation of the line of best - fit $y = 4.26x+10.908$ and $x = 31$ (miles of shoreline).
Step2: Substitute $x$ into the equation
Substitute $x = 31$ into $y = 4.26x+10.908$. So, $y=4.26\times31 + 10.908$. First, calculate $4.26\times31$: $4.26\times31=(4 + 0.26)\times31=4\times31+0.26\times31=124+8.06 = 132.06$. Then, $y=132.06+10.908=142.968\approx143$.
Answer:
D. 143 feet
