A group of farmers collected data on the number of foxes and the number of rabbits seen on their properties per week. Ths scatter plot below shows the data they collected. Th farmers used the equation y = -3x + 100 to model the data collected. Based on the equation, which statement is true? A. Each additional fox is associated with 3 more rabbits. B. Each additional fox is associated with 3 fewer rabbits. C. Each additional fox is associated with 100 more rabbits. D. Each additional fox is associated with 100 fewer rabbits.

Which line has the greatest slope?

The electric power consumed each month by a chemical plant is thought to be related to the average ambient temperature (x₁), the number of days in the month (x₂), the average product purity (x3), and the tons of product produced (x4). The past year's historical data are available and are presented in the following table: Y 240 236 270 274 301 316 270 296 267 276 288 261 25 31 45 60 65 72 80 84 75 60 50 38 X2 24 21 24 25 25 26 25 25 24 25 25 23 Fit a multiple linear regression to predict power (y) using x1, X2 X3, and X4. Calculate R2 for this model. Round your answer to 3 decimal places. 91 90 88 87 91 94 87 86 88 91 90 89 X4 100 95 110 88 94 99 97 96 110 105 100 98

An electronics store sells new and used Z-phones. The store manager made the scatter plot below to show the selling prices of used Z-phones and their ages, in monthsIf these data are modeled by the line y=-10x+410, which best describes a valid prediction the manager could make, based on the dataA.If the store sells a Z-phone that is 30 months old, it will probably sell for only $50B.If the store sells a brand-new Z-phone, it can expect a customer to pay about $410C.For every one-month increase in phone age, the price a customer will pay increases by about $10D.For every one-year increase in phone age, the price a customer will pay decreases by about $10

Interpret the unstandardized coefficient for highest years of schooling. E.g., Is the relationship positive or negative? How does a one-unit change in schooling (i.e. an increase in one-year of education) influence Y?  Interpret the constant (i.e. the intercept) in the equation? What does it indicate? Calculate the average number of hours watched for someone with 12 years of education.

A study was done to look at the relationship between number of vacation days employees take each year and the number of sick days they take each year. The results of the survey are shown below.   Vacation Days 2 7 0 3 2 9 15 3 8 0 11 Sick Days 10 3 6 5 4 5 0 4 2 11 0   Interpret the y-intercept in the context of the question: If an employee takes no vacation days, then that employee will take 8 sick days. The y-intercept has no practical meaning for this study. The best prediction for an employee who doesn't take any vacation days is that the employee will take 8 sick days. The average number of sick days is predicted to be 8

What is the intercept b? Round to the nearest integer.

If aN O for a moving object, then the object is moving in a straight line. %3D O True O False

The following data was collected to explore how the number of square feet in a house, the number of bedrooms, and the age of the house affect the selling price of the house. The dependent variable is the selling price of the house, the first independent variable (x1�1) is the square footage, the second independent variable (x2�2) is the number of bedrooms, and the third independent variable (x3�3) is the age of the house.
