Answer:
54.56
Step-by-step explanation:
Given:
Mean, u = 48
Standard deviation, = 4
Test score = 5%
Required:
Find the raw score, X.
Having a test score of 5% means the Zscore has to correspond to 95%, ie, 1 - 0.05 = 0.95.
Thus,
To get X, use the formula:
= 48 + (4 * 1.64)
= 48 + 6.56
= 54.56
The anxiety test score that would put someone in the top 5% is 54.56

Answer:
C (see below)
Step-by-step explanation:
The function f(x) is written in vertex form:
f(x) = a(x -h)^2 +k . . . . . scale factor 'a', vertex (h, k)
The vertex of function f(x) is (1, -5).
The function g(x) = f(x +2) represents a shift left by 2 units. When the vertex of f(x) is shifted left 2 units, it becomes (1-2, -5) = (-1, -5).
The graph with the vertex in this location is the third problem attachment, shown below.
