A local university is planning to invest $500,000 every 3 months in an investment which earns interest at the rate of 12% per year compounded quarterly. The first investment will be at the end of this current quarter. a) To what sum will be the investment grow at the end of 5 years. b) How much interest will be earned during this period?

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

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
