Answer:
x = (y + 26)/5
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out equation
y + 6 = 5(x - 4)
Step 2: Distribute
y + 6 = 5x - 20
Step 3: Isolate <em>x</em>
y + 26 = 5x
Step 4: Isolate variable <em>x</em>
(y + 26)/5 = x
Step 5: Rewrite
x = (y + 26)/5
Z = (x - mean) / SD
The z-score for x = 63 is: z = (63 - 65.5) / 2.5 = -1
The z-score for x = 70.5 is: z = (70.5 - 65.5) / 2.5 = 2
Therefore we need the probability that -1 < z < 2. This is equivalent to the probability that z < -1, subtracted from the probability that z < 2. From z-tables, we find that this is equal to 0.9772 - 0.1587 = 0.8185. This means that 81.85% of women's heights fall within this range.
