A text book publisher wants to estimate the number of sentences per paragraph in a history textbook. The publisher count the number of sentences in 150 randomly selected paragraphs. The results are shown in the table. Based on the data what is the mean number of sentences per paragraph in the textbook?
A. 4
B. 5
C. 10
D. 15

Answers

The limiting behavior of a function describes what happens to the function as x → ±∞. The degree of a polynomial and the sign of its leading coefficient dictates its limiting behavior.

Using the weighed mean, it is found that the mean number of sentences per paragraph in the textbook is given by:

B. 5

What is the weighed mean?

The weighed mean is given by the sum of all elements in a data-set multiplied by it's weight, divided by the sum of the weights.

In this problem:

The sum of the values multiplied by it's weights is: 1 x 0 + 2 x 3 + 3 x 20 + 4 x 43 + 5 x 36 + 6 x 25 + 7 x 10 + 8 x 8 + 9 x 2 + 10 x 3 = 750.

Considering that there are 150 books, we have the mean is:

M = 750/150 = 5.

Hence option B is correct.

find the value of x cubed minus 2x squared minus 7x + 5 of x=1/2-√3 ​

Answers

9514 1404 393

Answer:

  3

Step-by-step explanation:

For f(x) = x^3 -2x^2 -7x +5 and x=1/(2-√3), we have ...

  f(x) = ((x -2)x -7)x +5

and ...

  x = 1/(2-√3) = (2+√3)/(2^2 -3) = 2+√3

Then ...

  f(2+√3) = ((2 +√3 -2)(2 +√3) -7)(2 +√3) +5

  = (3+2√3 -7)(2+√3) +5

  = 2(√3 -2)(√3 +2) +5 = 2(3 -4) +5 = -2 +5

  f(1/(2 -√3)) = 3

_____

If you really mean x = (1/2) -√3, then f(x) = (42√3 -3)/8.
