f of x equals negative 9 6 times x plus 205 54 and r squared equals 0 76   2018 WGU, Powered by GeoGebra Question 10 of 12 Question10 This is not a form  we suggest that you use the browse mode and read all parts of the question carefully  Based on this model, whatisthe weight of a man who is active 7 hours per day  Byf(7)151f(7)151, a man who is active 7 hours per day would weigh approximately 151 pounds  Byf(7)160f(7)160, a man who is active 7 hours per day would weigh approximately 160 pounds  Byf(7)132f(7)132, a man who is active 7 hours per day would weigh approximately 132 pounds  Byf(7)138f(7)138, a man who is active 7 hours per day would weigh approximately 138 pounds  Correct  Substitute x   7into the regression function to calculate the interpolation value  Jessica collected some monthly rent data in a local neighborhood to determine a reasonable price to rent a2000 squarefoot house  First, she made the following scatterplot and ran a linear regression   The graph plots Area in Square Feet on the horizontal axis and Rent in Dollars on the vertical axis  A line passes through the points (600, 680), (1000, 1200), and (1600, 2040)  A series of data points closely follows the line and the equation near the line reads  h of x equals 1 35 times x minus 140 54   2018 WGU, Powered by GeoGebra Question 11 of 12 Question11 This is not a form  we suggest that you use the browse mode and read all parts of the question carefully  Which statement is true about this regression  Byh(3,000)3,909h(3,000)3,909, the monthly rent for a3,000 square foot house is approximately $3,909  Byh(1,500)1,884h(1,500)1,884, the monthly rent for a1,500 square foot house is approximately $1,884  A quadratic regression should be used instead of a linearregression  Byh(200)129h(200)129, the monthly rent for a200 square foot house is approximately $129  Incorrect  The value x   3,000is too far away from the data range  This result should not be trusted  This is an extrapolation concern  The following scatterplot, with a linear regression, shows the relationship between the number of hours using a smartphone per day and the percentageof people with depression  Two outliers were investigated and then removed   The graph plots Number of Hours Using Smartphone per Day on the horizontal axis and Percent of People with Depression on the vertical axis  A line passes through the points (1, 10) and (10, 26)  A series of data points closely follows the line and the equation near the line reads  f of x equals 1 73 times x plus 8 34 and r squared equals 0 56
