Write an equation in slope-intercept form of the trend line. (1 point)
To write an equation in slope-intercept form of the trend line, we need the slope and y-intercept. Unfortunately, without the specific data points or additional information, I am unable to calculate the slope and y-intercept accurately.
y25
x10
Based on the information given (y = 25, x = 10), we can write the equation of the trend line in slope-intercept form:
y = mx + b
Substituting the given values:
25 = m(10) + b
Without specific information about the slope or another data point, we cannot determine the exact equation of the trend line.
The graph shows average annual temperatures in the United States in degrees Fahrenheit. What statistical investigative question can be inferred from the graphical display, and how should it be answered? (1 point) Responses What percentage of years shown in the graph had a temperature below 60 degrees Fahrenheit? Ninety percent of the years shown had a temperature below 60 degrees Fahrenheit. What percentage of years shown in the graph had a temperature below 60 degrees Fahrenheit? Ninety percent of the years shown had a temperature below 60 degrees Fahrenheit. What percentage of years shown in the graph had a temperature higher than the U.S. temperature in 2011? Thirty percent of the years shown in the graph had temperatures higher than the temperature in 2011. What percentage of years shown in the graph had a temperature higher than the U.S. temperature in 2011? Thirty percent of the years shown in the graph had temperatures higher than the temperature in 2011. What percentage of years shown in the graph had a temperature above 60 degrees Fahrenheit? Fifty percent of the years shown had a temperature above 60 degrees Fahrenheit. What percentage of years shown in the graph had a temperature above 60 degrees Fahrenheit? Fifty percent of the years shown had a temperature above 60 degrees Fahrenheit. What percentage of years shown in the graph had winters in which the temperature was below 55 degrees Fahrenheit? Twenty percent of the years shown on the graph had winters in which
The statistical investigative question that can be inferred from the graphical display is: "What percentage of years shown in the graph had a temperature below 60 degrees Fahrenheit?"
To answer this question, we would need to analyze the data points on the graph and determine the number of years where the temperature was below 60 degrees Fahrenheit. We can then calculate the percentage of those years out of the total number of years shown in the graph.
