Question

before taking a prescription medication, mias systolic blood pressure was 142. after three weeks of taking the medication, mias systolic blood pressure was 118. calculate the relative change. (round to the nearest thousandth if needed.) provide your answer below:

Explanation:

Step1: Find the absolute change

Absolute change = New value - Original value.
Here, new value = 118, original value = 142.
Absolute change \(=118 - 142=- 24\)

Step2: Calculate the relative change

Relative change formula is \(\text{Relative change}=\frac{\text{Absolute change}}{\text{Original value}}\)
Substitute the values: \(\text{Relative change}=\frac{-24}{142}\)
\(\text{Relative change}\approx - 0.169\)

Answer:

\(-0.169\)
