a ships officer sees a lighthouse at a 37° angle to the oath of the ship. after the travels 2000 m the lighthouse is at a 90° angle to the shops path. what is the distance between the ship and the lighthouse at this second sighting?

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

i think its a.

hope this

answer is  

c.

56

hope you get this right
