Alfred is practicing typing. the first time he tested himself, he could type 30 words per minute. after practicing for a week, he could type 33 words per minute. after two weeks he could type 36 words per minute. based on this pattern, predict how fast alfred will be able to type after four weeks of practice. 42 words per minute 46 words per minute 36 words per minute 39 words per minute

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
