Answer:
34; 34 inches is not long enough
Step-by-step explanation:
A doormat is the shape of a rectangle and its area uses A=l*w. If the area is 714 and its length is 21, then 714 = 21*w. Solve for w.
714=21w
714/21= 21w/21
34 = w

Step-by-step explanation:
<h2><u>Mean and Median</u></h2>
<h3>solve for the mean and median of the following data: 20, 10, 15, 18, 12, 17</h3>
<h3><u>Mean</u></h3>
To find the mean of a data set, use the formula:
<u>mean</u> = <u>sum of the data points</u>/<u>number of the data points</u>
We will determine the sum of the data points.
- 20 + 10 + 15 + 18 + 12 + 17 = 92
Since the number of data points is 6, we will divide the sum and the number of data points as shown in the formula above.
<u>Answer:</u>
- The mean of the data set is <u>15.3</u>.
<h3><u>Median</u></h3>
To find the median of the data set, arrange the data set into ascending order and the value in the middle is the median. The median should be an even number.
- 20, 10, 15, 18, 12, 17
- 10, 12, 15, 17, 18, 20
The middle value is 15 and 17. Find out their sum and divide it into 2.
<u>Answer:</u>
- The median of the data set is <u>16</u>.
