The value of X in this equation would be -1.
Z = ( X - Mean ) / SD
z = ( 646 - 597 ) / 39
z = 49/39 = 1.25
With the z-score table:
for z = 1.25, p = 0.8944 ( probability that the cost will be lower than $646 )
1 - 0.8944 = 0.1056
Answer: <span>The probabilit</span>y is 0.1056
Test them
(x,y)
(2,4) and (3,3)
see if get true
(2,4)
-3(2)+5(4)=2(2)+3(4)
-6+20=4+12
14=16
false
(3,3)
-3(3)+5(3)=2(3)+3(3)
-9+15=6+9
6=15
false
neither
