Lapatulllka [165]

Answer:

The representative sample contained more girls than boys.

Step-by-step explanation:

A "sample" of something is a small part of it. A "representative sample" is a small part of the students that represents them all. A random sample would not include all 160 students. It is more likely that there would be more girls than boys, than more boys than girls. In total, there are more girls than boys: 95 girls to 65 boys. It is more likely that a sample of the total students would be just like the total, but smaller.

I need help immediately with these two problems.
Iteru [2.4K]

Answer:

(1) 25.5 meters square

(2) 1.5 hours

Step-by-step explanation:

(1) Tucker painted 2/3 of his deck before lunch so he has 1/3 of the deck to paint after lunch.(1 - 2/3). So you do 1/3 of  of the deck (76 1/2 meters square) to paint. 1/3 x 76 1/2 is 25 1/2 meters square. 25 1/2 is 25.5.

(2) This is like the last problem just with different numbers.  She has 3/5 of 2 1/2 hours left. So you times 3/5 by 2 1/2. You get 1 1/12 which is 1.5.
