The first one is 621 and the second one is C

(1.) Your answer is 621. The formula for the area of a rectangle is A = l*w, where l is the length and w is the width. Your length is 23 and your width is 27. So, now you have A = 23*27, which equals 621. 621 = 23*27.

(2.) First, find the area of the whole rectangle. Your length is 9 ft and your width is 8 ft. A = 9*8, which is 72. Next find the area for the play area. Your length is 4 ft and your width is 3 ft. A = 4*3, which is 12. Subtract 72-12 and you have your answer. Your answer is 60.

Ksivusya [100]
Hello!

I don't exactly understand your question. If you mean to be asking whether or not 1002 is geater than 100, it is.

If you mean to be asking to add it: 102 + 900 + 100 = 1102

Answer:

The correct option is C:

C) The representative sample contained more girls than boys.

Step-by-step explanation:

It is given that a random sample is chosen from a total students of 160 students. The sample can be of 10,15 or any small numbers of students as compared to 160. However, a sample cannot be of 160 students as it is defined as a population in this case.

A random sample is always unbiased. Which means that the sample chosen should have around the same proportion of girls to boys as it is in the population of 160.

We know that:

Total boys in 160 = 65

Total girls in 160 = 95

Proportion of girls to boys = 95/65 = 1.462

Which means that for every 1 boy, there are 1.462 of girls.

The same ratio is held in a random sample, hence the total number of girls will be greater than boys
