Answer 1

Given: A dietician recorded the consumption of calories during the week by his patient as follows: Monday : 3105 cal. Tuesday : 1795 cal. Wednesday : 1500 cal. Thursday : 1407 cal. Friday : 2615 cal. Saturday : 1800 cal. Sunday : 1913 cal.

To Find: The average of consumption of calories by the patient.

Solution: We calculate average by the given formula,

Average= Sum of the observations/ Total Number of observations

Sum of the observations =3105 +1795+1500+1407+2615+1800+1913 calories.

Number of the days=7

Average calories consumed by the patient=

                 ( 3105 +1795+1500+1407+2615+1800+1913 )/ 7

              = 14,135/7

              = 2,019.28(approx)

Answer:- The average of consumption of calories by the patient is 2,019.28.
