Answer:
<em>Statistical inference</em>
Step-by-step explanation:
The confidence interval is used to give a range of values for a target population while applying the law of probability. Inferential statistics makes use of data obtained from a given population to predict and make a conclusion on a study.
Statistical inference is the process of applying the tools for inferential statistics to analyze data gotten from a given fraction of the population. This process is based on probability and random sampling.
<em>When a confidence interval is used to conclude a population study, it is certainly based on probability. Therefore the correct option is statistical inference. </em>
It has one solution. when discriminant=0, tangent to the curve( means touches at one point ) hence one solution.
function that could be used to represent the area of the triangular region formed by the girls' locations and the campsite at 2:30 p.m. is 
.
<u>Step-by-step explanation:</u>
First, Kara walks straight East twice as much as Lindsay walks North. Let "x" be the number of miles walked by Lindsay, Kara has walked twice that at the same time i.e.
⇒ 
Then we need to add one mile to what Kara walked i.e.
⇒ 
and half a mile (0.5 mi) to what Lindsey walked i.e.
⇒ 
. We represent the distances covered East and North from the campsite in the following sketch: Distances covered are straight & are in right triangle !
Area of triangle = 
⇒ 
⇒ 
⇒
Therefore , function that could be used to represent the area of the triangular region formed by the girls' locations and the campsite at 2:30 p.m. is .
