Tamara find the sum of two number cubes boat at the same time. The chart below shows all taxable Sams from the 36 possible combinations on rolling to number K cubes. How many times for tomorrow expect the sum of two cubes equal to nine if she rolls to number cubes 252 times

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
