Weeks of Training 10 Finishing Time (min) 45 1. Using Desmos technology and the data provided. create a scatter plot and find the line of best fit. What is the equation of this line in y=mx+b form? (LT#1.4, 1.5) 7 50 4 65 25 38 2. What is the slope (m) value? What does the slope mean in this context? Explain in words. (LT#1.10) 28 40 16 48 9 58 1 70 5 53 8 60 3. What is the y-intercept (b) value? Is it meaningful in this context? Why or why not? Explain in words. (LT#1.10) 25 45 30 39 21 45 7 58 15 49 4. According to the equation, if someone were to train for 72 weeks, what would their finishing time be? Is this reasonable in this context? Why or why not? SHOW YOUR WORK. (LT#1.6) 5. Using the equation for the line of best fit, if someone ran a 51-minute race, calculate how many weeks they trained. SHOW YOUR WORK. (LT#1.6)

Ican interpret and represent the remainder in division calculations sensibly for the context (eg if we wont to know how many 40 seat buses will be needed to transport 170 students for on excursion, we divide 170 by 40 and realise buses and another smaller vehicle to that we need 4 transport 10 more students) solve the following questions. show your work! 11) the zoo had 420 butterflies that needed to be transported to a new enclosure. the boxes that the butterflies would be moved in only hold 80 butterflies in each. how many boxes would they need? 2 12) each classroom in the school can have exactly 25 students, if there are 345 students in the school how many full classrooms are there?
