In class, we saw a complex equation that could be used to calculate the error in a value obtained from a calibration curve. Based on this equation, why is it helpful to
have a highly sensitive detector? That is, why does a highly sensitive detector
decrease the error in concentration values?

The data shown in the table below represents the weight, in pounds, of a little girl, recorded each year on her birthday. age (in years) weight (in pounds) 2 32 6 47 7 51 4 40 5 43 3 38 8 60 1 23 part a: create a scatter plot to represent the data shown above. sketch the line of best fit. label at least three specific points on the graph that the line passes through. also include the correct labels on the x-axis and y-axis. part b: algebraically write the equation of the best fit line in slope-intercept form. include all of your calculations in your final answer. part c: use the equation for the line of best fit to approximate the weight of the little girl at an age of 14 years old.

Prove that the value of the expression 7^8–7^7+7^6 is divisible by 43.
