Answers b and c are 'way off (wrong). Answer d is not negative, and thus could not be the correct answer. That leaves Answer a: the range is influenced too much by extreme values.
Answer:(that was a joke)
1.) acute
2.) right
3.) obtuse
4.) acute
5.) obtuse
6.) right
Step-by-step explanation:
if hes doing advanced stuff like isosceles equilateral and that then im sorry for the answer.
Since derivatives lower the degree of polynomials, if you want the second derivative to be zero you have to choose first-degree polynomials.
So, you have
Two polynomials are linearly independent if they are not multiples of each other. So, for example, you might choose and to find two linearly independent solutions.
As for
we want a second-degree polynomial with leading coefficient 1/2 so that we will get 1 when deriving it twice:
If we impose the conditions
we have
So, our solution will be in this form:
To fix , we use the second condition:
So, we have fixed and the solutions is
The z-score will be given by:
z=(x-μ)/σ
given that:
x=94
μ=mean=84.5
σ=standard deviation=4.4
thus
z=(94-84.5)/4.4
z=2.1591
