Your heart rate before exercising would probably be the at rest rate of say about 50-60 beats per minute whereas immediately after exercise it could easily be say 115-130 and depending on age there is an optimum heart rate for each age range which decreases somewhat with age. Timing for a full minute your heart rate is best as it will give the actual count whereas if you just do it for 10 seconds and then multply by 6 it would assume it will be consistent whereas it could decrease during the minute so the actual measured count for a full minute is more accurate.
I think homologous structures is a great example and idea that supports the theory of evolution. Homologous structures shows us how our futures evolved by natural selection.
If we talk about mathematics and the science behind geography, east and west are directions that may represent infinitely. The reason why quantity exist is to measure and create scales on how far an object is from the origin or the point of locus.
These directions can be compared to a line in math which is an endless and limitless progress of points connected without a direction however, incorporating a specific direction could still represent a endless point of west; an endless point to east. Conclusively both are infinite and long unless determined and specified by a continouous measure.
First step
build the table (<span>see attached table)
</span> using a calculator we find the regression line
Number of values=9
Regression line equation
Y=a+bx
y-intersection a= - 0.1697
<span>slope b=0.0187</span>
y=-0.1697+0.0187X
