ain, would you have children?" Readers were invited to send a response to this question by mail. Of the approximately 10,000 responses Landers received, approximately 70% said "no." The sample:_____.A) Is probably not representative because more than 10,000 people responded.B) Has little bias because more than 10,000 people responded, yielding a very large sampleC) Is probably representative of all parentsD) Is probably not representative of all parents because people who feel very strongly about this issue are more likely to respond than people who do not.

Answer:

Option D is correct

Let f\left(x\right)=\frac{2}{x}f ( x ) = 2 x and g\left(x\right)=\frac{x}{x-1}g ( x ) = x x − 1. Find the domain of \left(\frac{
Black_prince [1.1K]

Answer:

The domain is  (-∞,0) ∪ (0,1) ∪ (1, +∞)

Step-by-step explanation:

In order to be able to compute f/g (x), we need that x is on the domain of f and in the domain of g.

f(x) = 2/x

In order to be able to compute f(x), we need that the denominator is different from 0, hence x≠0.

g(x) = x/x-1

In order to be able to compute g(x). we need x-1 to be different from 0, thus x≠1.

We also need the denominator of f/g (x) to be different from 0, hence g(x) ≠ 0. In order for g(x) = x/x-1 to be 0, the numerator x should be 0, as a result, we need x≠0 in order to have g(x) ≠ 0.

The domain of f/g (x) is every real nummber besides 0 and 1, in other words, it is (-∞,0) ∪ (0,1) ∪ (1, +∞).

Doctors are interested in seeing if lifting weights to alleviate back pain is effective. Twenty five volunteers are asked to ran
goldenfox [79]

Answer:

Comparing means from dependent samples.

Step-by-step explanation:

In the scenario described above, the 25 sampled individuals were used to test the effect of weightlifting on alleviating back pain. The samples used were not changed nor altered during the study as the same subjects who were tested to measure their level of pain before lifting weight were the same group subjected to the actual weight lifting test and again had their level of pain tested. Since only one group was involved in the study ( a single group was tested on neutral and actual treatment). Hence, the study used dependent samples to compare the average level of pain.

Whats the area of the circle above
Anna35 [415]

Answer:

<h2>The answer is option A</h2>

Step-by-step explanation:

Area of a circle = πr²

where

r is the radius of the circle

From the question

r = 15.2 cm

The area of the circle is

A = (15.2)²π

= 231.04π

= 725.833566685386...

We have the final answer as

<h3>725.8 cm²</h3>

Hope this helps you
