Answer:
2
Step-by-step explanation:
It's just a multiplication problem, 8 x 1/4 is 8/4, which is equal to 2.
Explanation
In this sample, people elect to participate or self-select to do the survey. Often, these folks have a strong interest in the main topic of the survey.
In essence, they volunteer to inform the trucking company about the activities of their drivers. That makes this a voluntary sample.
Answer: Voluntary Sampling Method
Answer:
at x= 0 and x= 1 and not at x= 3.
Step-by-step explanation:
We have the functions,
and
.
It is given that,
At x=0, x=1, and x=3, 
i.e. 
i.e. 
i.e. 
i.e. x= 0 and (x-1)= 0
i.e. x= 0 and x= 1.
Also, after plotting the graphs of both the functions, we see their intersection point are (0,1) and (1,3).
Thus, we get that
at x= 0 and x= 1 and not at x= 3.

Answer:sin (140°)
Explanation:Angle addition formulas are used to express the trigonometric function in terms of the sum/difference between two angles α and β
These rules are shown in the attached image.
Now, the given expression is::
sin97°cos43°+cos97°sin43°We have:
α = 97°
β = 43°
Comparing the given formula with the general formulas in the image, we would find that the given formula represents the sum of the sin of two angles.
Therefore:
sin97°cos43°+cos97°sin43°
= sin (97°+43°)
= sin (140°)
Hope this helps :)
