Could you attach a photo of what you need assistance with?

Step-by-step explanation:

The missing angle is 70 Degrees.  

Step-by-step explanation:

You have a 9 degree angle on the opposing side making the complete angle of the missing one plus the 20 degrees 9 degrees. Now simply subtract your 20 degrees from the 90.  =70

the answers are in the images, i received 100% on this assignment. hope this !

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
