What is the answer to 0.03x^2+0.07x+0.03=0

x=(-7+√13)/6

or

x= (-7 -√13)/6

Step-by-step explanation:

0.03x^2 = 0.07x + 0.03=0

first, multiply everything by 100 to make life easier

3x^2 +7x+3=0

then use quadratic formula

D=b^2 -4ac

D=49-3*3*3 = 13

x=(-7+√13)/6

or

x= (-7 -√13)/6

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
