Assume that n 70. Find the average of this set of numbers' .
{n, 2n, 3n, 4n, 5n, 6n, 7n, 8n, 9n)

answer: 1 and 3

step-by-step explanation:

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=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
