Compare the ratios 2 to 7 and 5:7 using the circles to model
DO
Using circles to model the ratios, divide both circles into
2v equal parts.
For the ratio 2 to 7, v parts should be shaded.
For the ratio 5:7 parts should be shaded.
The ratio 2 to 7 is
the ratio 5:7.

answer: 177/8

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

the answer is: -22 also a
