Answer:
7
Step-by-step explanation:
4/2 = 14/x, cross multiply and simplify, x=7
Plug in 2 for x. f(20=2-51 = -49
4 + 2h < -3
2h < -7
h < -3.5
x ∈ (-∞, -3.5)
Answer: To find the critical value, follow these steps.
Compute alpha (α): α = 1 - (confidence level / 100)
Find the critical probability (p*): p* = 1 - α/2.
To express the critical value as a z-score, find the z-score having a cumulative probability equal to the critical probability (p*).
