ns. Look at the Model Its. How is finding 14··40• 130 like solving 14··405 c···130?Why are both 45 and 46 reasonable predictions for the number of country songs played in 130 songs? When 40 songs were played, 30% were rock songs. Why should you not expect exactly 30% of the 130 songs played to be rock songs?How can you use data from an experiment to make a prediction about how often an event will happen in a future experiment with more or less trials?Can you use Luis’s results to predict how many times another person’s playlist will play country songs? Explain. Reflect Think about all the models and strategies you have discussed today. Describe how one of them helped you better understand how to make predictions using experimental probability. 1

care to share were the trapezoid shown is ?

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true

the answer i believe is 27 units.
