Given:
let h be the high quality bean
let c be the cheaper bean
h + c = 160
6h + 3.25c = 160*4.97
6h + 3.25c = 795.20
h = 160 - c
6(160 - c) + 3.25c = 795.20
960 - 6c + 3.25c = 795.20
-2.75c = 795.20 - 960
-2.75c = -164.80
c = -164.80 / -2.75
c = 59.92 or 60 lbs
h = 160 - c
h = 160 - 60
h = 100 lbs
Sarah should blend 60 lbs of cheap coffee bean and 100 lbs of high quality coffee bean.
Given that the scatter plot contains a trend line that passes through (2,5) and (3,7),
the slope of this line is given by:
slope,m=(7-5)/(3-2)=2/1=2
this shows a positive slope, but other than this we cannot draw any further details concerning the points such as the correlations, hence the answer is:
<span>D. There is not enough information.</span>
Which variable are you talking about? In this question x is 4 and y is 5.
Hope this helped!
Good Luck!
