One estimate for the ideal body weight of a woman is shown b
Solution
Linear model for the estimate of the ideal weight of a woman using w as ideal body weight(in kgs) and h as height over 5 feet(in inches).
 1 feet=12 inches => 5 feet=12x5 inches= 60 inches
 Therefore the linear model is given by
w=58+2.7(h-60)
B)
 w=58+2.7(h-60)
 w=58+2.7h-162
 w=2.7h-104
 it is in the form y=mx+c where m is the slope of the equation.Hence in this equation m=2.7.
 Since we are calculating the weight based on height the correct answer is option (c)The rate of change of weight is 2.7 kilograms per inch.
 (C)
 If a women is 5\'4\" tall i.e. 5x12+4=64 inches tall
 => h=64, we need to find w frm the model
 w=58+2.7(h-60)
 w=58+2.7(64-60)
 w=58+2.7(4)
 w=58+10.8
 w=68.8 kilograms
 Therefore if a woman is 5\'4\" tall then the model predicts her weight to be 68.8 Kg
(D)
 w=73 Kilograms
 we have to find the height of the woman
 w=58+2.7(h-60)
 73=58+2.7(h-60)
 2.7(h-60)=73-58
 h-60=15/2.7
 h-60=5.5
 h=60+5.5
 h=65.5 inches
 we know that 60 inches is 5 feet. Therefore the height of the woman is
 h~5 feet and 5.5 inches.
