he graph below shows the distances in miles traveled by a helicopter in a certain number of hours. Based on the graph, which of the following equations indicates the correct variables, and in how many hours does the helicopter travel 3000 miles if it travels at the same speed?

Graph titled Motion of a Helicopter shows Time in hours on x axis and Distance in miles on y axis. A straight line joins the ordered pairs 0, 0 and 2, 200 and 4, 400 and 6, 600.

x = 100y, the helicopter travels 3,000 miles in 32 hours
y = 100x, the helicopter travels 3,000 miles in 30 hours
y = 100x, the helicopter travels 3,000 miles in 32 hours
x = 100y, the helicopter travels 3,000 miles in 30 hours

Answer 9

every one hour is 100 miles

Answer 10

Consider the following dot plot. Of the following statements, which two characteristics of this dot plot make the median a better choice than the mean to summarize the center of the distribution?

A dot plot with an axis marked from 0 to 10 at increments of 1 is shown. Plot shows 8 dots at 0, 7 dots at 1, 5 dots at 2, 4 dots at 3, 2 dots at 4, and 1 dot at 10.

The mean is equal to the median and the data are symmetric.
The peak is equal to the median and the data are skewed.
The data are skewed and there is an outlier.
The data are symmetric and there is an outlier.
