Plug all the point into your calculator. Not sure if you need it y=mx+b but the R for that is r= -1
Step-by-step explanation:
Given that,
The mass of a patient = 70 kg
A 70kg patient has approximately 8 pints of blood.
The patient donates 470mL of blood.
We know that,
1 pint = 568 mL
8 pints = 4544 mL
Required fraction,
![\dfrac{470}{4544}=0.1\\\\=\dfrac{1}{10}](https://tex.z-dn.net/?f=%5Cdfrac%7B470%7D%7B4544%7D%3D0.1%5C%5C%5C%5C%3D%5Cdfrac%7B1%7D%7B10%7D)
So, the required fraction is approximately
