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.

Answer:1.84
Step-by-step explanation: We can add this in a very easy way.
Step 1- We can put the 1 in the ones place as if there is no number before a decimal (which is the case for the first number) we can assume it is 0.
Step 2- We can then place the decimal point after the 1 and then put 0.8 since there are no more numbers that are at the tenths
Step 3- At the end we add the .04 (also known as 0.04) as there are no more places in both the numbers that are in the hundredths (and in 1.8, it can also be known as 1.80 as there are none!)
Hope this helps!
