Find the unit rate. Jack shells 315 peanuts in 15 minutes

21 shells per minute

Step-by-step explanation:

So in order to find out how many Jack shells per minute we have to divide the number of peanuts by the minutes it take to shell the peanuts

315/15=21

so for every minute that passes 21 peanuts are shelled

i think 5 miles per hour

step-by-step explanation:

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
