3. It collects data on members of a group  -  Survey.

4. It does not equally favor all members of a group - Biased sample.

5. It includes all members of a group   -  Population.

6. It analyzes data collected from a group - Mean.


I have matched all concepts in accordance with statistical use, hope it helps.

Adamo saved 13 pictures oh his digital camera for a total of 12021.1kb. He deleted 32 pictures for a total of 29590.4kb If there
rosijanka [135]

First solve the original number of pictures. The original number of picture is 108 + 32 – 13 which is equal to 127 pictures. Then solve the size of each picture,

12021.1 kb / 13 pic = 924.7 kb / pic

So the original storage is 127 pic ( 924.7 kb / pic) = 117,436.9 kb

Drag and drop an answer to each box to correctly complete the explanation for deriving the formula for the volume of a sphere.
Advocard [28]
The volume of a sphere is given by:

V= \frac{4}{3} \pi r^{3}

So, we need to deduct this equation. We will walk through Calculus on the concept of a solid of revolution that is a solid figure that is obtained by rotating a plane curve around some straight line (the axis of revolution<span>) that lies on the same plane. We know from calculus that:

</span>V=\pi \int_{a}^{b}[f(x)]^{2}dx
<span>
Then, according to the concept of solid of revolution we are going to rotate a circumference shown in the figure, then:

</span>x^{2}+y^{2}=r^{2}
<span>
Isolationg y:

</span>y= \sqrt{r^{2}-x^{2}}<span>

So,

</span>f(x)=y=\sqrt{r^{2}-x^{2}}<span>

</span>V=\pi \int_{a}^{b}[\sqrt{r^{2}-x^{2}}]^{2}dx
<span>
</span>V=\pi \int_{a}^{b}(r^{2}-x^{2})dx<span>

being -r and r the limits of this integral. 

</span>V=\pi \int_{-r}^{r}(r^{2}-x^{2})dx
<span>
Solving:

</span>V=\pi[r^{2}x-\frac{x^{3}}{3}]\right|_{-r}^{r}

Finally:
<span>
</span>V=\pi(r^{3}-\frac{r^{3}}{3})-\pi(-r^{3}+\frac{r^{3}}{3})= \frac{4}{3} \pi r^{3}<span>
</span><span>
</span>

Julia is offered a job selling advertising for two different companies. Company A offers a base salary of $30,000 per year plus
patriot [66]
A=30000+0.03S and B=25000+0.05S.
When A=B, 5000=0.02S, so S=$250000 when the earnings are the same.
The slope of A is smaller than that of B. In excess of this value of S B pays more than A and below it A pays more than B.
So answer option B. (When S=0, clearly A is better than B. Put S=$300000, A pays $39000 and B pays $40000).
