Change 807 mm to hm.

Answer to Problem 1T
Solution:
Explanation of Solution
Given: The units, 807mm.
Explanation:
There are 10 millimeters (mm) in 1 centimeter, 10 centimeters in 1 decimeter, 10 decimeters in one meter, 10 meters in one decameter, 10 decameters in one hectometer and 10 hectometers in one kilometer.
The conversion from millimeter to hectometer includes five steps where for each step, the given term is divided by 10. Hence, for five steps, 807 shall be divided by 100,000.
Hence, it is required to move the decimal place to five places left as shown below.
Hence, the amount of 807mm. into hm. comes out to be

- A movie studio wishes to determine the relationship between the revenue generated from the streaming of comedies and the revenue generated from the theatrical release of such movies. The studio has the following bivariate data from a sample of fifteen comedies released over the past five years. These data give the revenue x from theatrical release (in millions of dollars) and the revenue y from streaming (in millions of dollars) for each of the fifteen movies. The data are displayed in the Figure 1 scatter plot.
