Answer:


Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 500
Standard Deviation, σ = 100
We are given that the distribution of SAT score is a bell shaped distribution that is a normal distribution.
Formula:

We have to find the value of x such that the probability is 0.64
P(X<x) = 0.64
Calculation the value from standard normal z table, we have, 


Answer:
Domain: {x|-∞<x<∞}
Range: {y|-∞<y≤3}
Transformation: Reflection across x-axis, left 2, up 3, vertical stretch of 2
Answer:
20
Step-by-step explanation:
4 * (2a − 1)
Let a=3
4 * (2*3 − 1)
Simplify inside the parentheses first
4 * (6 − 1)
4 * (5)
