Shondra frequently goes running in the mornings. She recorded the outside temperature and the number of miles for each run. Shondra created the following graph. Which trend line would be most appropriate for her data?Group of answer choicesA positive quadratic trend line.An increasing exponential trend line.A negative quadratic trend line.An increasing linear trend line.A decreasing exponential trend line.

When do you need to add a trendline on a plot ?Group of answer choicesTo find the error level on dataTo see if data is closely matchedTo see how close data is to a special fitTo see if data is following a correct trend

Jacob is a marathon runner. He wants to know if a relationship exists between male runners’ ages and their marathon times. He used data from the New York City Marathon to create the scatterplot below.Select the trend line and reasoning that would best show the relationship between marathon runners' ages and race times.Group of answer choicesAn exponential trendline is best because older men tend to have much slower running times.An exponential trendline is best because men between 25 and 30 are the fastest. Race times increase for men who are both older and younger than 25–30.A quadratic trendline is best because older men tend to have much slower running times.A quadratic trendline is best because men between 25 and 30 are the fastest. Race times increase for men who are both older and younger than 25–30.A linear trendline is best because it is the simplest model of the relationship between running times and age.

Identify the right type of chart using the following hints.Hint 1: This chart is often used to visualize a trend in data over intervals of time.Hint 2: The line in this type of chart is often drawn chronologically

Copy and paste the following data into Excel. Create a scatterplot of the data and use the scatterplot to determine if the data would best be represented by a linear, quadratic, or exponential trendline.x y6.2 9.912.4 205.1 12.242.8 18.025.7 11.327.4 7.054.2 15.315.7 11.553.4 16.84Group of answer choicesThere is no discernable trend.ExponentialQuadraticLinear
