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
9≤c + 1
In this question we will first solve for the variable. ( i.e. c )
so,
subtracting both sides by 1 we get
8 ≤ c
or
c ≥ 8
And we know that if we have ≤ or ≥ we have a HARD dot on the point.
So, our graph will start from point 8 goes to the right.
hope this helped.. :)
