A company makes spherical tanks that store chemicals. Their standard model has a diameter of 6 meters, but a
customer needs a larger tank whose capacity is 2.5 times the volume of the standard model.
What is the approximate diameter of this larger tank?
Round to the nearest tenth.
m

60%

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
