Answer:
Known:
• a book have front, back and 200 pages
• front= 0.7 mm
• back= 0.7 mm
• each page= 0,14 mm
ask:
calculate the minimum thickness...?
answer:
a. 200 p × 0,14 = 28 mm
b. front + back = 0.7+0.7= 1.4 mm
Thickness= 28+1,4 = 29,4 mm
I hope this helps
if u have question let me know in comments^_^

Answer:
Answer : A
Step-by-step explanation:
The given data is 25 th percentile is 64, 50th percentile is 74 and 75 th percentile is 80.
percentage : 25    50   75
   score        : 64    74    80
Median:- The median is obtained by first arranging the data in ascending or descending order and applying the following rule.
If the number of observations is odd, then the median is  observation
 term
 term
If the number of observations is even, then the median is  observation and  observations.

given n=3, middle term is '74'
  In this given data the median is (M) = 74
Interquartile range IQR = median of upper half-median of lower half
                                        = 80-64
                                        = 16
                             IQR = 16
 
        
             
        
        
        
The augmented matrix is,

We have given system of linear equation is,

<h3>What is the meaning of augmented matrix?</h3>
In an augmented matrix, each row represents one equation in the system and each column represents coefficients (with signs) of variables or the constant terms.
So, the first row is

the second row is

and the third row is

Therefore the augmented matrix for this linear system is,
