The value of Adam's model railway is $550. This value increases exponentially at a rate of r %
per year.
At the end of 5 years the value will be $736.
Calculate the value of r.

(c)

Step-by-step explanation:

Given

The initial value of Adam's model is

the value increases exponentially with the rate of

Time period

Final amount

Exponential growth is given by

Putting values

Option (c) is correct

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
