I'm pretty sure the answer is 2.9 because It's closer to 3 than 2
Using sampling concepts, it is found that the population of interest is given by:
All American teens who are between the ages of 13 and 17.
<h3>What is sampling?</h3>
It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.
<h3>For example:</h3>
I want to estimate the proportion of New York state residents who are Buffalo Bills fans. So i ask, lets say, 1000 randomly selected New York state residents wheter they are Buffalo Bills fans, and expand this to the entire population of New York State residents.
In this problem, a sample of American teenagers aged 13 to 17 was taken, hence all American teenagers aged 13 to 17 is the population of interest.

<span><span>2/7 times 2 by 5 and times 7 by 5 also then that would equal 10/35
then you times 3 by 7 and times 5 by 7 to get 21/35 then add 10 and 21 to get 31 then it will be 31/35 then try to reduce it but u cant so the answer is 31/35</span></span>
Step-by-step explanation:
Draw the triangle formed by the ray.
The hypotenuse of the triangle is:
c² = a² + b²
c² = (-5)² + (2√7)²
c² = 25 + 28
c = √53
Therefore:
cos β = -5 / √53
Or, as a proper fraction:
cos β = -5√53 / 53
