I am guessing they are asking for the perimeter.
Answer: 36cm
The answer is D for this problem. Btw u can use a site called deez
Part A: Chose some value for x, that means any amount of books to print for example 100 books, so x=100
Replace x=100 in C(x) and solve:
C(100)=3.5*100+1200=1550
Part B: Replace C(x) by 1900 and solve for x from the given equation:
1900=3.5x+1200
3.5x=1900-1200
x=700/3.5= 200
Part C: the statement C(20)=1270 means that 1270 is the cost for printing 20 books.
Part E: C(40.5)=1341.75 I think this statement is incorrect given the context because x means number of books to print so this value must be an integer number.
<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>.
