Answer:

11. The sampling method is biased. This is because the researcher only interviews people coming out of the restaurant instead of people in the restaurant or walking on the street. This would be called convenience sampling.

12. There is bias in the question. The writer prefers chocolate over vanilla by the words used to describe the two flavors.

(Sorry if this was too late for you by the way.)

The table represents a linear function. The rate of change between the points (–5, 10) and (–4, 5) is –5. What is the rate of ch

vladimir1956 [14]

<h2>Answer:</h2>

The rate of change between the points (–3, 0) and (–2, –5) is:

-5

<h2>Step-by-step explanation:</h2>

The rate of change between the points (-5, 10) and (-4, 5) is -5.

Now we are asked to find the average rate of change between (-3,0) and (-2,-5)

We know that the average rate of change between two points (a,b) and (c,d) is calculated by the formula:

$Rate\ of\ change=\dfrac{d-b}{c-a}$

Here we have:

(a,b)=(-3,0) and (c,d)=(-2,-5)

Hence, the average rate of change is:

$Rate\ of\ change=\dfrac{-5-0}{-2-(-3)}\\\\\\Rate\ of\ change=\dfrac{-5}{-2+3}\\\\\\Rate\ of\ change=-5$

Also, we know that for any linear function the average rate of change is same between any two points.

Hence, the answer is:

-5

How do you evaluate log2 1/64

OverLord2011 [107]

If it is written as log base 2 (1/64) then you make it equal a question mark (believe me)

then you rewrite to exponential form so you would write it as 2^? = 1/64
and 1-64 is the same as 2^-6, so negative 6 is your answer
