Answer:
B) 0.24
Step-by-step explanation:
As we plot the point on the best fit line for the concentration of 0.2 the absorbance level predicted should be 0.24.
The denominator is 4 and the numerioar to make factor 1/2 would be 4/8 then 1/2
One form of the relation of inverse variation is y = k/x.
first step: Find the value of k: Taking the values x=5 and y = 4, 4=k/5, or k=20. Then, y = 20/x.
Next: Let y = 7 and find the corresp. value of x: 7=20/x, or 7x=20, or
x = 20/7 (answer)
For the first one just do the multiplication as you do normally.
For the second one, you have to put a zero behind before calculating the numbers in front
