Answer:
Step-by-step explanation:
<u>Given:</u>
- f(x) = 7x² - 3
- g(x) =
<u>To find f(g(x)), substitute x in f(x) with the value of g(x):</u>
- f(g(x)) =
= 7(2x³) - 3 = 14x³ - 3
This represents the amount of money she earns every hour, where x is the number of hours.
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
