- Total Body Water Accurate prediction of total body water is critical in determining adequate dialysis doses for patients with renal disease. For white males, total body water can be estimated by the function T(A,W,B)=23.040.03A+0.50W0.62B where T is the total body water in liters, A is age in yr, W is weight in kg, and B is the body mass index. Source: Kidney International. Find T(55,75,30).arrow_forwardSales Barnes & Noble had annual sales of $6.8 billion in 2013 and $6.1 billion in 2015. Use the Midpoint Formula to estimate the sales in 2014. Assume that the annual sales followed a linear pattern.arrow_forward
