Respuesta :
Number of red blood cells = [tex]4.5*10^{6}[/tex]
Number of white blood cells = 5000 or we can write this as [tex]5*10^{3}[/tex]
We have to find how many times more red blood cells are there than white in the sample. so we will divide the two to get the answer.
[tex]\frac{4.5*10^{6}}{5*10^{3}}[/tex]
= [tex]0.9*10^{3}[/tex]
= [tex]9*10^{2}[/tex] = 9*10*10 = 900
Hence, the red blood cells are 900 times more than white blood cells.
Answer:
Red blood cells are 900 times of white blood cells in the blood sample of Laura.
Step-by-step explanation:
Sample of Laura's blood sample contains number of red plus cells = 4.5[tex]10^{6}[/tex] and number of white blood cells = 5×[tex]10^{3}[/tex]
Now we calculate the ratio of red blood cells and white blood cells
= 4.5×[tex]10^{6}[/tex]÷5[tex]10^{3}[/tex]
= 4.5×[tex]10^{3}[/tex]÷5
= 4500÷5
=900
Now scientific representation of data will be
