A gum all machine has 300 red gumballs. If the red gumballs are 50% of the total number of gumballs

300 other colored gumballs

Step-by-step explanation:

If red is 50% of the gumballs, there are 300 more gumballs of other colors, ex blue, green, yellow

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
