The following scatterplot gives the height and arm span of 20 students. Data of Height and Arm Span of 20 students 8 8 Arm Span (inches) 60 y = 1.1165x - 7.6429 o 50 55 60 65 70 75 Height (inches) Use the graph and the given trendline, y = 1.1165 x - 7.6429, to predict the arm span of a student who is 68 inches tall. (Round your answer to one decimal place) Numero inches As Kennedy arrived at the airport departure gate to fly home, her cell phone had almost no charge. She quickly located an outlet and plugged in her phone. Use the trend line and equation, y = -0.0024 x2 + 1.0595 x + 9.4716, to estimate the charge Kennedy can expect if her phone charged for 45 minutes? Cell Phone Charge over Time 100 Battery Charge (26) 585:88388 y =-0,0024x* + 1.0595x + 9.4716 20 40 60 80 100 120 Time Plugged In (minutes) (Round your answer to one decimal place) Numero %
