Transforming to Achieve Linearity Answers

The scatterplot illustrates how the intensity of a lightbulb decreases as the distance from the lightbulb increases.Which transformation would display linearized data?

Given the following computer output, select the correct least-squares regression line:

Given the following least-squares regression line, how many seconds does this model predict a 7-foot pendulum would take to complete one period?

Because the number of pepperoni slices is related to the surface area of the pizza, and surface area is related to the square of the diameter, the students performed a regression analysis of y = the number of pepperoni slices and x = diameter2. Which is the equation of the least-squares regression line that the students calculated?

In a class activity, students collected data on the average number of pepperoni slices on various sizes of pizzas.A "New York” style pizza has a diameter of 18 inches. Use the least-squares regression line to predict the average number of pepperoni slices that the students could expect to find on a "New York” style pizza.

The scatterplot shows the relationship between the time a water balloon is filled from a running faucet and the volume of the balloon.Which transformations would display linearized data? Check all that apply.

The scatterplot shows the balance of a retirement account that grows exponentially.Which transformation would linearize this exponential data?

The relationship shown in the scatterplot can be linearized and modeled by the equation:ln(Balance) = 3.2189 + 0.1(Time)Based on this information, approximately how much does the model predict the account balance to be after 25 years of savings?

The scatterplot shows the relationship between the length of a pendulum and the time it takes to complete one full swing.Which transformations would linearize these data using a power model? Check all that apply.
