Ximena bikes 20 miles from her home to her favorite lunch spot and then bikes back. She bikes
with the wind to lunch and against the wind on the way home. Her total travel time on the bike is 3.5 hours. When biking with no wind her average speed is 14 miles per hour.

1. Write and solve an equation to calculate the average speed of the wind. Show your work.

If square root x = -7, then x= -49 true or false

Find the ratios of the corresponding sides

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?
