Answer:
Option (C): The Rome data center is best described by the mean. The New York data center is best described by the median.
Step-by-step explanation:
1. Rome
Minimum=0
Maximum=16
Median ,
Mean = 8
Standard Deviation(σ)=5.4
As, difference between , Maximum -Mean =Mean - Minimum=8
So, Mean will Worthy description to find the center of Data set, given about Rome.
2. New York
Minimum=1
Maximum=20
Median , Q2 = 5.5
Mean = 7.25
Standard Deviation(σ)=6.1
As, for New york , Mean is not the mid value, that is difference between Mean and Minimum is not same as Maximum and Mean.
As, you can see , the three Quartiles , are very close to each other, it means , other data values are quite apart from each other. So, Mean will not appropriately describe the given data.So, in this case Median will suitable to find the center.
Answer:
Total cost would be $ 1,285,000
Step-by-step explanation:
Consider fixed cost is x and variable cost is y per unit, ( both are in dollars )
So, the total cost of 19000 units = fixed cost + variable cost × number of units produced
= x + 19000y
if y = $ 41 per unit,
Then total cost = x + 19000(41) = x + 779000
According to the question,
x + 779000 = 1,080,000
⇒ x = 1,080,000 - 779000 = 301000
Thus, fixed cost = $ 301000
Hence, the total cost for 24,000 units = 301000 + 24000(41)
= 301000 + 984000
= $ 1,285,000
Answer:
x = 65
Step-by-step explanation:
Since we know the bottom line is = 180 (since it shows the top line)
The angle to the left of x is 90, which leaves x + 25 = 90
x = 65
Y = kx + b
(0,9) x = 0; y = 9
y = kx + b
9 = k*0 + b
9 = b
(3,0) x = 3; y = 0
y = kx + 9
0 = k*3 + 9
-9 = 3k
k = -3
