and if the result is a multiple of 4 then the answer would be 1 by 3
Answer:
Yes, it is representative because each type of book was represented in the approximate proportion that exists in the library.
Step-by-step explanation:
Given is a chart, showing the distribution of the number of books in a library.
Also given that Sahira chooses a random sample from the library and records the type of books in the chart below.
Sahira's sample can be said to be representative because given that books are taken at random. So just because literacy books were more we cannot say it is not representative II option is not right, because each book was not chosen uniquely, just random books were drawn
Lastly The Answer is C) Yes, it is representative because each type of book was represented in the approximate proportion that exists in the library is right, because each book selected represents the sample from population of full library books.
A) <span>3x + </span><span>2.5y= 27
B) 5x – 2.5y = 5
</span>Adding A and B we get
8x = 32
x = 4
A) 3*4 + <span>2.5y= 27
</span>A) 12 + <span>2.5y= 27
</span>A) <span>2.5y= 15
y = 6

What is the image of (3,7) after a reflection over the line y= -x? ... (-2,2) is just (3-5,7-5) Just subtract 5 from each coordinate.
Answer:
1 = 56°
Explanation:
Interior angles 1 and 83° must add up to the external angle 139° because of the reason ‘exterior angles of a triangle’.
Angle 1+83°=139° (ext angles of triangle)
Angle 1 = 139°-83°
Angle 1 = 56°
