Hello friends, we are going to write here.
00:03
This is our data.
00:04
So if i write here for this value of car over time purchased is given, we are going to write exponential regression equation, determine how long it be until car's value is $5 ,500.
00:16
So basically if i write here for this mean of x is 2, right.
00:23
So if i write here, how can we say, or we can calculate this, this is 0 plus 1 plus 2 plus 3 plus 2.
00:31
4 divided by 5 which is 10 divided by 5 that is 2 so basically if i write here for this this is mean of why is we need to write here for this this must be written as 20300 plus 17 353 so let's erase this to make it more clear plus 13 13 936 3 3 if i write here for this 12, 592, so this must be erased to make it more clear.
01:12
And 10, 5, 2, 3, and this total value must be divided by 5.
01:19
We are going to write here for this.
01:22
This will be.
01:24
So this must be, we need to write a 747505 divided by 5, which is 14 ,9.
01:34
Now if i write here for this value of a is 20 ,167, we need to write here for this and value of v is 0 .84 .84918.
01:53
We are going to write here for this.
01:56
This must be written as exponential regression.
02:02
Regression if i write here for this equation is y value is equivalent to we need to write here for this a multiplied by b to power x which is equivalent to y is equal to 20 ,167 multiplied by 0 .849 raise to power x so basically if i write here for this what would be our y value is equal to 5500 which is 5500 is equivalent to 20 ,0617.
02:39
0 .849 raise to power 6...
