Sara receives her cell phone bill on the first day of each month. This month, she exceeded her allowed number of minutes for the
month. Sara highlighted the 13 longest phone calls on her bill and wants to find the average number of minutes per call. Help Sara find the average of these 13 calls by applying the appropriate measure of central tendency. In the form of a paragraph, explain in complete sentences the measure of central tendency that you used to find the average. Explain the steps necessary to find the average, include the final answer and what the final answer means in terms of the data presented in the table. Complete your work in the space provided or upload a file that can display math symbols if your work requires it.
In a short answer, to find average you need to add it all up and divide by the number of things you added. Ex. say I want to find the average for my english class, my grades are 90, 98, 100, 87, and 70. I would start by adding them up to get 445. then since i have 5 grades, i would divide the sum 445 by 5 and get an 89 as my average.
(Everything in this answer is example only, not my real grades.)
The quotient of two positive integers or two negative integers is positive. The quotient of a positive integer and a negative is negative. Hope you understand how to divide integers now.
