+) An ice sculpture is melting at a constant rate. Its weight changes -1, pounds every hour. 5
.) What is the total change in weight of the
1
sculpture after 3 1/2hours?
(answer) pound

.

step-by-step explanation:

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

1st part is 64,000,000

2nd part 500,000
