A large construction company wants to review the ages of its sales representatives. A sampling of the ages of 25 sales reps are
given: 50 42 32 35 41 44 24 46 31 47 36 32 30 44 22 47 31 56 28 37 49 28 42 38 45 The following histogram is a representation of the data. Calculate the median ages
What you have to do to find the median of the data is first put that data into order numerically. You can go largest to smallest or smallest to largest, it doesn't matter. <span>
Once you put them into order, you count towards the middle. You have 25 data points, so the middle, which will be your median number, will be 13 points in.
Given that the gardener wants the number of trees in each raw to be equal to the number of rows, then let the number of in each row be x this means that the number of rows will be x. Thus the total number of trees will be: Total=(number of rows)*(number of trees in each row) hence: 122500=x×x 122500=x² hence x=√122500 x=350 thus the number of rows will be 350 and the number of trees in each row will be 350
This problem can me modelled with an exponencial formula:
P = Po * (1+r)^t
Where P is the final value, Po is the inicial value, r is the rate and t is the amount of time.
In this problem, we have that the inicial population/value is 27000, the rate is -8/9 (negative because the population decays), and the time t is in months, so as the rate is for every 4 months, we use the value (t/4) in the exponencial.
