C I would say the answer C because 400 people is a little too much people to interview and if the people are by the tennis courts those answers would be bias because they would say yes

Answer:

C. The manager visits a park and interviews people who were waiting to use the tennis courts.

Step-by-step explanation:

It's biased because the manager is clearly asking people only interested in tennis, not a clearly random sample.

The domain of both

Margarita [4]

Answer:

The domain of function $h(x)$ is set of all real numbers.

Domain: (-∞,∞)

Step-by-step explanation:

Given:

$f(x)=x-6$

$g(x)=x+6$

the domain of both the above functions is all real number.

To find domain of :

$h(x)=f(x)g(x)$

Substituting functions $f(x)$ and $g(x)$ to find $h(x)$

$h(x)=(x-6)(x+6)$

The product can be written as difference of squares. $[a^2-b^2=(a+b)(a-b)]$

∴ $h(x)=x^2-36$

The degree of the function $h(x)$ is 2 as the exponent of leading term $x^2$ is 2. Thus its a quadratic equation.

For any quadratic equation the domain is set of all real numbers.

So Domain of $h(x)$ is (-∞,∞)

A Freight train is traveling 30 miles per hour. An automobile starts out from the same place 1 hour later and overtakes the trai

Mazyrski [523]

40 I believe because the space of the auto mobile catching up to the train is 4 hours. 4 times 30 is 120 miles so u need to figure out a number that can reach 120 in three hours. 3 times 40 is 120
