The average farm in the United States in 2004 contained 443 acres the standard deviation is 42 acres use chebyshevs theorem to find the minimum percentage of data values that will fall in the range of 338- 548 acres

.95

step-by-step explanation:

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

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
