Answer:
8000 cm^2 or 8 m^2
Step-by-step explanation:
We can convert 2 meters to centimeters, simply by multiplying the ,meters value by 100. So, the converted dimensions of the rectangle are 200 cm by 40 cm. Multiplying to get the area, we have 8000 cm^2. This could also be expressed in terms of m^2 as 8 m^2.
For each, it's easier to find what one item costs.
$6 for 3 = 6 divide by 3 = $2 per item
$9 for 6 = 9 divide by 6 = $1.50 per item
$10 for 8 = 10 divide by 8 = $1.25 per item
$1.40 per item
The best deal for lowest price per item is the $10 for 8
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.
