Question

1. show work

. the table below shows the number of cars jing sold each month last year. what is the median of the data in the table?

1. a square with sides lengths measure 6 inches. what is the perimeter and area of the square? (show work)

Explanation:

24. Median Calculation

Step1: Sort the data

First, list the number of cars sold: \(13,15,16,19,19,22,25,25,26,27,28,29\)

Step2: Find the median

Since there are \(n = 12\) data points (even number), the median is the average of the \(\frac{n}{2}\)th and \((\frac{n}{2}+1)\)th values. \(\frac{n}{2}=6\), \(\frac{n}{2}+1 = 7\). The 6th value is \(22\) and the 7th value is \(25\). Median\(=\frac{22 + 25}{2}=\frac{47}{2}=20.5\)

25. Perimeter and Area of a Square

Step1: Perimeter formula

The perimeter formula of a square is \(P=4s\), where \(s = 6\) inches. \(P=4\times6=24\) inches

Step2: Area formula

The area formula of a square is \(A=s^{2}\), where \(s = 6\) inches. \(A=6^{2}=36\) square inches

Answer:

1. J. \(20.5\)
2. Perimeter: \(24\) inches, Area: \(36\) square inches
