What is the quadratic curve of best fit?y = .5 - 0.06x - 0.03y = .5x2 + 0.06x + 0.03y = .5x2 - 0.06x + 0.03y = .5x2 + 0.06x - 0.03 The distance a marble has traveled down a slantedboard was measured by a 3rd grade class. Based on the curve of best fit, estimate the distance the marble will travel in 20 seconds.152175199215 Bomani's math club has been fundraising to prepare for the upcoming Science Meets Math demonstration. What is the equation for the line of best fit?y = 17.27x + 23.255y = 17.27x + 25.181y = 17.27x + 27.893y = 17.27x + 30.112 Bomani's math club has been fundraising to prepare for the upcoming Science Meets Math demonstration. Based on the equation, how much money will they have saved at week 12?\$175.40\$163.25\$197.55\$230.50 The average hourly wage for a technical worker over a10-year period is shown belox.  What is the quadratic curve of best fit for the information?y = 0.002x2 + 1.246x + 5.633y = 0.002x2 + 1.246x + 8.279y = 0.002x2 + 1.246x + 10.675y = 0.002x2 + 1.246x + 13.772 The average hourly wage for a technical worker over a10-year period is shown belox.  Based on the curve of best fit, estimate the hourlywage of the worker at 20 years. \$25.25\$28.17\$34.12\$36.40
