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)

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

correct answer is b. 27/8
