The length of a rectangle is (2x+5) units and the breadth is (3x-1) units .Find the perimeter and the area of the rectangle.

Answers

Answer 1
Answer:

Answer:

Perimeter =  10x + 8 units.

Area = 6x^2 + 13x - 5 units^2.

Step-by-step explanation:

The perimeter  is 2*length + 2*breadth

= 2(2x + 5) + 2(3x - 1)

= 4x + 10 + 6x - 2

= 10x + 8 units.

The area = length * breadth

= (2x + 5)(3x - 1)

= 6x^2 - 2x + 15x - 5

= 6x^2 + 13x - 5 units^2.

Math Twelve hundred students participated in the school chemistry contest. A random sample (Sample 1) from grades 9 and 10 showed scores of: 84, 50, 99, 83, 50, 78, 88, 85, 77, and 96.

A random sample (Sample 2) of grades 11 and 12 showed scores of: 57, 62, 86, 82, 74, 78, 96, 90, 97, and 83.

What is Statistics?

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

A random sample (Sample 1) from grades 9 and 10 showed scores of:

84, 50, 99, 83, 50, 78, 88, 85, 77, and 96.

Ascending order:  50, 50, 77, 78, 83, 84, 85, 88, 96, 99

The sample has an even number of scores, so the median is the average of the two middle scores:

(83 + 84)/2

= 83.5

Therefore, the median of Sample 1 is 83.5.

For sample 2, the data set is 57, 62, 86, 82, 74, 78, 96, 90, 97, and 83.

Ascending order of scores: 57, 62, 74, 78, 82, 83, 86, 90, 96, 97

The sample has an even number of scores,

so the median is the average of the two middle scores: (82 + 83)/2

= 82.5

Hence, the median of Sample 1 is 83.5 and  median of Sample 2 is 82.5.
