Imagine that you are planning to estimate the price of the average book at your college bookstore. The bookstore carries 13,000

titles, but you plan to sample only 200 books. You will select a sample of 200 books, record the price of each book, and use the average of the 200 books to estimate the average price of the 13,000 books in the bookstore. Questions: What is the sample in this study, and what is the population

Answer: "13,000 books" represents the population.

"200" books represents the sample.

Step-by-step explanation:

  • A population is the term that denotes a whole large possible group of individuals, objects, events or measurements.
  • A subset of population is known as ample.
  • When population is too large to the researcher  , then it uses sample to represent the entire population.

Here,  "13,000 books" represents the population.

"200" books represents the sample which is a subset of 13,000 books.

1. A sphere is sliced so that the cross section does not intersect the center of the sphere.
stich3 [128]
1. The shape of cross-section is a circle.
2. The face parallel to ABCD is EFGH. Since this is a a rectangular shape,

A = L*H = 12*6 = 72 cm^2

3. The cross-section parallel to ABC is DEF with h = 12 ft, b= 5ft (where h is the height and b is the base of a right angled triangle).

Area, A = 1/2 *b*h = 1/2*5*12 =30 ft^2

4. Plane BDHF is a rectangle shape whose length is the diagonal of ABCD.

Diagonal BD = sqrt (AB^2+BD^2) = sqrt (8^2+7^2) = 10.63 cm.
Perimeter, P = 2(BD+DH) = 2(10.63+6) = 33.26 cm

What is the length of the hypotenuse of the triangle?
atroni [7]

Step-by-step explanation:

Hey there!

Here;

ABC is a Right angled triangle.

Taking reference angle as angleA.

Now;

Hypotenuse (h) = AB

Perpendicular (BC)= 24 ft.

Base(AC)= 10 ft.

Now, Using Pythagoras relation;

h =  \sqrt{ {p}^{2}  +  {b}^{2} }

Put all values.

h =  \sqrt{ {24}^{2}  +  {10}^{2} }

Simplify it.

h =  \sqrt{576 + 100}

h =  \sqrt{676}

Therefore, h= 26ft.
