Answer:
v = 1.62 m/s
Step-by-step explanation:
Given that,
Distance covered by the mouse is 5.56 m is in 3.42 seconds.
We need to find the velocity of the mouse. It is equal to the total distance covered divided by time taken. So,
So, the velocity is 1.62 m/s.
Using the trend line, it is found that the year in which the record for the 100-meter dash was 11.8 seconds was:
A. 2005
<h3>What is the regression line?</h3>
It is given by:
In which:
- y is the record in seconds.
- x is the number of years since the year 2000.
The record will be of 11.8 seconds x years after 2000, considering that y = 11.8, hence:
Hence in 2005, and option A is correct.

If you would like to divide 2 by 1 6/7, you can do this using the following steps:
1 6/7 = 13/7
2 / 1 6/7 = 2 / 13/7 = 2/1 / 13/7 = 2/1 * 7/13 = 14/13 = 1 1/13
The correct result would be 1 1/13.
