She can add 35 and 9 which equals 44
Answer:
X₀ = 71.65
Step-by-step explanation:
given,
mean (μ ) = 64
standard deviation (σ) = 9
σ² = 81
selected candidate are top 20 % candidate
P( X > X₀) = 0.2


P( Z > Z₀) = 0.2

X₀ = 71.65
Hence, the cut off score is equal to X₀ = 71.65
The two equations are:
y=.17x+35.96
y=.12x+49.96
He would have to drive 280 miles for both of them to cost the same.
C. The only reason why you didn’t have a problem is that I don’t have a lot to say because if I don’t have to say that I don’t know why I don’t have to say that I have a bad attitude
<span>For the graph y = 1, the slope of a line that is perpendicular would be infinity because it lies vertically. The slope of the line parallel to it will have the same slope with y=1 which is zero because it lies flat or horizontally. Hope this answers the question. Have a nice day.</span>
