f(x) = -x + 2

f(-1) This means that they want you to find the value of f(x) or y when x = -1.

f(x) = -x + 2 Substitute/plug in -1 into "x" since x = -1

f(-1) = -(-1) + 2 (two negative signs cancel each other out and become positive)

f(-1) = 1 + 2

f(-1) = 3

Katen [24]

Answer: 687

Step-by-step explanation:

normally distributed

μ = 498

σ = 108

Top 4%

P(X > a) = 0.04

P(Z > a-498/108) = 0.04

Using the table attached, for the top 4%:

0.50 - 0.04 = 0.46

a-498/108 = 1.75

a-498 = 189

a = 687

The minimum score for the scholarship is 687.
