1a. 3:4 , 3 to 4 , 3/4

1b. 4:7, 4 to 7, 4/7

1c. Ratio of faces to the total

2. 11:28

the answer is 62.8 cubic units

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
