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
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
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.

Calculate the unknown variable value .
Do not answer with a one answer, blank or a ridiculous answer please this is serious.
Answer:
x=75°and y=x= 75°
Step-by-step explanation:
Reason: opposite angles are equal and how I got 75 is by drawing an extension line and finding the other angle (i.e. angle on a straight line=180) so 180-105=75.
Solve by elimination:
3x + 4y = 0
5x-3y = -58
A (6, -8)
B (-6, -8)
C (-8, 6)
D ( 8, 6)
Answer:
x=−8
y=6=
Step-by-step explanation:
3x+4y=0
5x−3y=−58
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
3x+4y=0,5x−3y=−58
To make 3x and 5x equal, multiply all terms on each side of the first equation by 5 and all terms on each side of the second by 3.
5×3x+5×4y=0,3×5x+3(−3)y=3(−58)
Simplify.
15x+20y=0,15x−9y=−174
Subtract 15x−9y=−174 from 15x+20y=0 by subtracting like terms on each side of the equal sign.
15x−15x+20y+9y=174
Add 15x to −15x. Terms 15x and −15x cancel out, leaving an equation with only one variable that can be solved.
20y+9y=174
Add 20y to 9y.
29y=174
Divide both sides by 29.
y=6
Substitute 6 for y in 5x−3y=−58. Because the resulting equation contains only one variable, you can solve for x directly.
5x−3×6=−58
Multiply −3 times 6.
5x−18=−58
Add 18 to both sides of the equation.
5x=−40
Divide both sides by 5.
x=−8
The system is now solved.
x=−8,y=6
Coordinates are: (-8,6)

Find the length of diagonal AV in a three dimensional figure.
Although I'm going to answer this question, I have to point out that this problem is NOT stated clearly. The problem being we don't know if angle AMV is a right angle.
But I'm assuming it is and thus we need to use the Pythagorean theorem.
AV=[tex]\sqrt{5^2+12^2}[/tex]
AV=13
