Julle needs to cut 4 pieces of yarn, each with the same length, and a piece of yarn 7.75 inches long. let x represent the length
of each of the equal pieces of yarn that julie decides to cut. what is the equation that can be used to determine the total length
of all of the yarn that she ends up cutting, y? is the graph of the equation continuous or discrete?
y=7.75r+4; discrete
y=7.75r+4; continuous
y=4r+7.75; discrete
y=4x+7.75; continuous

For a science project, a high school research team conducted a survey of local air temperatures. based on the results of the survey, the found that the average temperatures were around 10 degrees higher than expected. this result was wrong. the trouble with the survey was that most of the locations were exposed to direct sunlight and located over asphalt or sand, which resulted in higher temperatures than normal. this is a classic example of an error in which phase of inferential statistics?
