.429 I think is the correct answer, I'm not 100% cure though.
The required probability for P(x<92) is 0.15866.
Given that,
Sample score = X = 92
Mean = μ = 98
Standard deviation = σ = 6
p(x ≤ 92 ) is to be determined
<h3>What is probability?</h3>
Probability can be defined as the ratio of favorable outcomes to the total number of events.
z = (X - μ) / σ
z = (92 - 98) / 6
z = - 1
Now
Probability,
p(x < 92) = P(z = -1)
p(x < 92) = 0.15866 (from z score table)
Thus, The required probability for P(x<92) is 0.15866.

Answer:
h(g(x)) = (1/5)x² +4/5
Step-by-step explanation:
Y = 1/2x + b
Plug in the point :)
-9 = 1/2(-4) + b
-9 = -2 + b
b = -7
Y = 1/2 -7
