The table shows the population of a school for the years 1992-2008. year: 1992, 1994 1996, 1998, 2000, 2002, 2004, 2006, 2008. population: 628, 656, 692,751, 793, 840 ,868, 902, 940. which of the following is the best prediction for the population in 2012? a. 1000 b. 1100 c. 1150 d. 2010

(A) 1000

Step-by-step explanation:

We will form a graph of the points give.

Let x denotes the year and y denotes the population in the corresponding year.

We get the best fir line as :

y =20.225x-39664

Now, to evaluate the population in 2012, we will put x=2012

y = 20.225(2012) - 39664

y = 1028.7

So the best prediction for the population in 2012  is 1000.

Hence, option (A) is correct.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
