(05.07 HC) A manager is assessing the correlation between the number of employees in a plant and the number of products produced yearly. The table shows the data: Number of employees(x) 0 50 100 150 200 250 300 350 400 Number of products(y) 100 1,100 2,100 3,100 4,100 5,100 6,100 7,100 8,100 Part A: Is there any correlation between the number of employees in the plant and the number of products produced yearly? Justify your answer. (4 points) Part B: Write a function that best fits the data. (3 points) Part C: What does the slope and y-intercept of the plot indicate? (3 points)

(08.07 MC) Which of the graphs below correctly solves for x in the equation −x2 − 6x + 5 = 2x + 5?

(05.07 MC) The scatter plot shows the number of flowers that have bloomed in the garden during the month of March: Part A: Using computer software, a correlation coefficient of r = 0.98 was calculated. Based on the scatter plot, is that an accurate value for this data? Why or why not? (5 points) Part B: Instead of comparing the number of flowers and the day in March, write a scenario that would be a causal relationship for flowers in a garden. (5 points)
