Method 2 is the least biased.

1) vegetarians are a select group, so they might have a certain biased perspective
2) if students are chosen randomly from every grade, all grades are included and there will be a variety of responses
3)not all students dislike the program, so it is an unfair representation
4)only students who have a strong opinion will complete the survey

Help!!! I don’t understand how to do this

Answer:

$f^{(k)}(x)=\dfrac{17k!(-1)^k}{(x-9)^{k+1}}$

Step-by-step explanation:

The question presumes you have access to a computer algebra system. The one I have access to provided the output in the attachment. The list at the bottom is the list of the first four derivatives of f(x).

The derivatives alternate signs, so (-1)^k will be a factor.

The numerators start at 17 and increase by increasing factors: 2, 3, 4, indicating k! will be a factor.

The denominators have a degree that is k+1.

Putting these observations together, we can write an expression for the k-th derivative of f(x):

$\boxed{f^{(k)}(x)=\dfrac{17k!(-1)^k}{(x-9)^{k+1}}}$

ANYONE KNOW THIS PLS HELP

In left one)
the 3 angles are equal so the sides are equal then we can say
$(3 \div 2) \times x + 6 = (2 \div 5)x + 9$
then x is 30÷11

the right one) is exactly similar
