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
Answer:
$7.08
Step-by-step explanation:
59 cents = 1 sq ft
? = 12 sq ft
To get from the 1 to the 12 we multiply by 12, so we must do the same to the 59 cents.
0.59 * 12 = 7.08
Therefore, the cost of 12 sq ft is $7.08.

Answer:
y = (-1/8)x^2
Step-by-step explanation:
Start with y = x^2. When the original parabola has been reflected across the x-axis, the pertinent equation becomes y = -x^2.
Now if this is scaled vertically by a factor of 1/8, we get:
y = (-1/8)x^2
