The scatterplot and regression line below show the relationship between how early students turned in an exam (measured by minutes remaining in the exam) and their exam scores. The fitted line has a yyy-intercept of 878787. What is the best interpretation of this yyy-intercept?

Write two point-slope equations for the line passing through the points (6, 5) and (3, 1)

Ahyperbola centered at the origin has a vertex at (-6,0) and a focus at (10,0)

At wind speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. the cyclic nature of wind and moving sand determines the shape and location of large dunes. at a test site, the prevailing direction of the wind did not change noticeably. however, the velocity did change. fifty-nine wind speed readings gave an average velocity of x = 1075 cm/sec. based on long-term experience, σ can be assumed to be 245 cm/sec. (a) find a 95% confidence interval for the population mean wind speed at this site. (round your answers to the nearest whole number.) lower limit cm/sec upper limit cm/sec
