Answer:
yes it is a polynomial function
The temperatures can be plotted and labelled on a number line as shown in the image attached below (see attachment).
Temperature can be represented on a vertical number line with 0 representing 0°F.
Temperatures above 0°F will be located above 0, while temperatures below 0°F will be located below 0.
Given the following temperatures: <em>-3.5℉
, 5℉, 1.5℉, -0.5℉, -2℉, 2.5℉ and -4℉</em>
Therefore, the temperatures can be plotted and labelled on a number line as shown in the image attached below (see attachment).

Be aware that arclength usually has a difficult function to integrate. Most integrable functions look like the above where a binomial is squared and adding the two terms will flip the sign of the binomial.

Answer:
The water dispenser's capacity in liters is 20liters
Explanation:
Given:
A water dispenser capacity = 20,000milliliters
To find
the capacity of the water dispenser in liters
To determine the capacity in liters, we will convert the capacity in ml to liters using the conversion:
1000ml = 1 liter
let the capacity of the water dispenser in Liters = y
The water dispenser's capacity in liters is 20liters
Answer:
The correct option is;
Low
Step-by-step explanation:
Given that the P-value of the linear correlation = 0.001, we have that the P-value is a demonstration that a linear correlation that has a value in the range of the given correlation is ,most arguably very low
From the z-table, a P-value of 0.001 corresponds to a z-value of -3.09, we have that in a normal distribution since 95% of the scores have a z-score of between -2 and 2, the z-score of -3.09 is very distant from the mean and having a low value, whereby the P-value shows that the likelihood of finding another linear correlation that is as far from the mean as the given correlation is very low.
