Distance = speed x time
2.257 x 9.111 = 20.563527 or 20
Answer:
equation y=-11/50-2
Step-by-step explanation:
Y intercept is where you start which is -2. Then you calculate the slope m=x1-y1/x2-y2
(a) Sample correlation ==> -0.7916
(b) Standard Deviation for Quantity ==> 801.6816
(c) Standard Deviation for Price ==> 39.1660
(d) Relation to coefficient on Price ==> <span>−16.2028</span>
