What is the mean of the data set?

2 answers:

6 0

The answer is given by the second choice: letter B. 14.75 is the answer because to get the mean, you should add all the numbers and then divide it by how many numbers there are. For example, in this case, you add 12, 17, 16, 10, 20, 13, 14, 14, 12, 12, 19, 18 to each other. You will get the answer 172. After that, you should divide 172 by 12 because there are 12 numbers in the data set.

On the graph of f(x)=cos x and the interval [0,2π), for what value of x does f(x) achieve a minimum?

Mariulka [41]

Answer:

$cos(\pi)=-1$

Step-by-step explanation:

$f(x)=cos (x)$

State that the values where cos x is minimum:

$x=\pi +2\pi n, n\in \mathbb{Z}$

$cos(0)=1\\$

$cos\left(\frac{\pi}{4} \right)=\frac{\sqrt{2} }{2}$

$cos\left(\frac{\pi}{2} \right)=0$

$cos(\pi)=-1$

$cos\left(\frac{3\pi}{2} \right)=0$

In the isosceles trapezoid, m∠S=68∘ . What is m∠Q ?

zmey [24]

9514 1404 393

Answer:

112°

Step-by-step explanation:

Same-side angles of a trapezoid are supplementary.

m∠P = 180° - m∠S = 180° -68° = 112°

The angles of an isosceles trapezoid match their symmetrical counterparts.

m∠Q = m∠P

m∠Q = 112°

Tim has an encyclopedia in 5 volumesA–C, D–F, G–J, K–N, and O–Z. Other than alphabetically (ascending or descending), how many w

Ira Lisetskai [31]

The first book can be any one of the 5.
   For each of those . . .
The 2nd book can be any one of the remaining 4.
   For each of those ...
The 3rd book can be any one of the remaining 3.
      For each of those . . .
The 4th book can be either of the remaining 2.
   For each of those . . .
The 5th book is the last one remaining.

Total number of ways to arrange the 5 books is

   (5 · 4 · 3 · 2 · 1) = 120 .

Cross off alphabetically ascending (1 way), and alphabetically
descending (1 way), and you're left with (120 - 2) = 118 ways.
