Below are 4 scatter plots reflecting relationships between two continuous variables. Select the statements that are true. Assume the X and Y axis are the same in each graph.

1. Graph the following function on the coordinate plane. y = -x² - 8x - 17 y

Given data of height, x and stories, y is of six notable buildings in a city. height numbers: 768, 628, 518, 511, 491, 478 and stories numbers: 52, 48, 46, 43, 37, 35.  What is the scope and y intercept of this? Round the scope to three decimal places as needed. Round the y-intercept to two decimal places as needed.

Let x be the average number of employees in a group health insurance plan, and let y be the average administrative cost as a percentage of claims. x 3 7 15 33 72 y 40 35 30 26 17 (a) Make a scatter diagram of the data and visualize the line you think best fits the data. A scatter diagram has a horizontal axis labeled "x (average number of employees)" with values from 3 to 72 and a vertical axis labeled "y (average cost as percentage)" with values from 17 to 40. The scatter diagram has 5 points. A pattern goes up and right from (13, 17) to (72, 40).     A scatter diagram has a horizontal axis labeled "x (average number of employees)" with values from 3 to 72 and a vertical axis labeled "y (average cost as percentage)" with values from 17 to 40. The scatter diagram has 5 points. A pattern goes down and right from (3, 40) to (72, 17).   A scatter diagram has a horizontal axis labeled "x (average number of employees)" with values from 3 to 72 and a vertical axis labeled…

Graph the line with slope 1 and y-intercept 4. Y=X+4

A survey was distributed to a group of people asking them how many times they had ordered takeout in the past week. They were also asked how much money they saved that week. The scatter plot displays the relationship between the data collected.  the trend line goes through the points (1,230) and (3,190). What is the equation of the trend line. The equation should be in slope form.  interpret the slope and y intercept in this context.  predict the amount of money a person save when they order takeout 9 times.

The number of calories in a food item depends on many factors, including the amount of fat in the item. The data below shows the amount of fat (in grams) and the number of calories in 7 beef sandwiches at McDonalds. The scatterplot displaying the relationship is shown to the right. Collection 1 Scatter Plot Sandwich Fat Calories 800- Big Mac Quarter Pounder w/ Cheese Dbl Quarter Pounder w/ Cheese Hamburger Cheeseburger Double Cheeseburger 29 550 600- 26 520 42 750 400- 9. 250 200- 12 300 23 440 McDouble 19 390 10 15 20 25 30 35 40 45 Fat 1. Describe the shape, the direction, and the strength of this relationship. 2. The regression equation for this data is Calories 1.52 Fat + 105. Explain the meaning of the slope and y-intercept in the context of this problem. 3. What is the correlation between Calories and Fat? 4. What number of calories does the regression model predict if a sandwich has 36 grams of fat? Remember to include units. B I U A Ix E E E x X, = E 12pt Paragraph Calories 囲

The following table shows retail sales in drug stores in billions of dollars in the U.S. for years since 1995. 220- 210 200 190 180 170 160 150 Year 0 130- 120- 110- 100- 90 801 6 12 15 Let S(t) be the retails sales in billions of dollars in t years since 1995. A linear model for the data is F(t) = 9.44t + 84.182. Retail Sales 85.851 108.426 141.781 169.256 202.297 222.266 3 6 9 12 15 Use the above scatter plot to decide whether the linear model fits the data well. The function is a good model for the data. The function is not a good model for the data Estimate the retails sales in the U. S. in 2015. billions of dollars.

The percent of defects is the x-coordinate, while the percent of new machines is the y-coordinate. So, the table of values corresponds to the points   (25,32), (20,40), (15,50), (10,65), (5,70), (0,85).     Question Using the linear relationship graphed above, estimate the percent of new machines if there is 12% defects in the shoes at various production facilities.  Provide your answer below:   _____
