Answer:
2nd and 3rd
Step-by-step explanation:
Answer:
Mean: 


Step-by-step explanation:
Given
See attachment for data
Solving (a): The mean
Mean is calculated as:

From the attached:

So, the mean is:



Solving (b): The median
; this is an even number. So, the median is:




This implies that the median is the average of the 7th and 8th item.
Next, is to order the data (in ascending order): <em>36.45, 38.03, 38.19, 39.17, 39.44, 40.1, 40.2, 40.2, 40.3, 43.1, 43.2, 43.4, 43.4, 43.4.</em>
The 7th and 8th items are: 40.2 and 40.2
The median is:



Solving (c): The mode
43.4 has the highest number of occurrence.
So:

Answer:- a
Step-by-step explanation:
Constant of Variation has this formula for Direct Variation.
y = kx
Where y = cost in dollars; x = length in meters; k = constant
We will use the formula for direct variation because the problem states that the cost varies directly to the length.
In the problem we need to get the constant of variation.
k = y/x
k = $4500 / 200 meter
k = $22.50 cost per meter.
A.) The equation relating C and s is:
k = C/s
* i just substituted C for y and s for x.
B.) The constant of variation represents the additional cost that the company will pay for every meter in length they add. which is $22.50 per meter.
C.) y = kx ; substitute C and s to y and x respectively;
C = ks
C = $22.50 * 700 m
C = $15,750
