Question

what is the midline and what does it represent in this context?

temperature (in degrees fahrenheit)

time (in hours)

(16, 67)
(40, 67)
(4, 47)
(28, 47)

answer attempt 1 out of 2

the midline is ( y = square ) and it represents

Explanation:

Step1: Find max and min values

Max temperature: $67^\circ\text{F}$, Min temperature: $47^\circ\text{F}$

Step2: Calculate midline value

$\text{Midline} = \frac{\text{Max} + \text{Min}}{2} = \frac{67 + 47}{2}$

Step3: Simplify the expression

$\frac{114}{2} = 57$

Answer:

The midline is $y = 57$ and it represents the average (mean) temperature over the measured time period.
