Answer:
$24.7million
$97.86million
$9.89million
Explanation:
From the sample , the lowest number is 16.3 and the highest number is 41, the range is
41-16.3
=$24.7 million
Σ
In the sample given the mean is . : (41 +40 +38+ 32+ 23+ 22+ 20+ 18+ 17.8 +16.3 )/10
mean=26.81
Using that, we can find the variance:
[(41-26.81)^2+(40-26.81)^2+(38-26.81)^2+(32-26.81)^2+(23-26.81)^2+(22-26.81)^2+(20-26.81)^2+(18-26.81)^2+(17.8-26.81)^2+(16.3-26.81)^2]/10=97.86million
The standard deviation is just the square root of the variance:
standard deviation=√(var)
, the standard deviation is the square root of 97.86, which equals $ 9.89 million
Answer:
$1,901,385
Explanation:
First unit produced by lambda took 5,000 hours to produce and required $30,000 worth of materials and equipment usage.
The second unit took 4,500 hours and used $24,000 worth of materials and equipment usage.
learning rate = time needed to produce second unit / time needed to produce first unit = 4,500 hours / 5,000 hours = 90%
materials and equipment usage rate = $24,000 / $30,000 = 80%
using the attached table of cumulative values, we can determine the cumulative improvement factors needed to solve this question:
Olsan's accumulated cost for producing 20 more guidance controls
- work hours = 4,500 x 14.61 (90% and 20 units) x $25 per hour = $1,643,625
- materials and equipment = $24,000 x 10.74 (95% and 20 units) = $257,760
- total = $1,901,385
