Answer:
Control limits for x_bar are between 59.076 and 60.924
Control limits for R are between 0.669 and 5.331
Explanation:
Given data:
x_bar = 60 mph
n = 10
R = 3 mph
Step 1: Factors (see table attached)
At n = 10, factors for computing control charts limits are,
A2 = Mean factor = 0.308
D3 = Lower range = 0.223
D4 = Upper range = 1.777
Step 2: Control limits for x_bar
Lower Control limit:
LCL = x_bar - A2*R = 60 - (0.308)(3) = 60 - 0.924 = 59.076
Upper Control limit:
UCL = x-bar + A2*R = 60 + (0.308)(3) = 60 + 0.924 = 60.924
The control limits for x_bar are between 59.076 and 60.924
Step 3: Control limits for R
Lower Control limit:
LCL = D3*R = 0.223(3) = 0.669
Upper Control limit:
UCL = D4*R = 1.777(3) = 5.331
The control limits for R are between 0.669 and 5.331
Hope this helps!
Answer: A public cloud
Explanation: The public cloud is described as processing resources that are provided through the wider internet by third-party suppliers, allowing them access for anyone who chooses to have or buy them. These can be complimentary or on-demand priced, enabling consumers to pay for the CPU cycles, storage, or connectivity these use only per use.
The biggest difference between private and public servers is that you're not responsible for maintaining a public cloud computing solution. Your information is stored in the server farm of the supplier and the data center is owned and controlled by the provider.
Answer: 0.48
Explanation:
P(A/B) = P(AnB)/P(B) where:
P(A/B) = The probability of event A occurring given that B has occurred.
P(AnB) = The probability of both events A and B occurring.
P(B) = the probability that event B occurs.
So let
P(A) = Probability that the residents of a household own 2 cars.
P(B) = Probability that the annual household income is greater than $25,000.
The question tells us that
P(A/B) = 0.8
Note that: P(A) = 0.7, P(B) = 0.6.
Since we want to work out P(AnB), because it gives the probability that residents have an annual household income over $25,000 and own 2 cars.
We would Rearrange our initial equation to make P(AnB) the subject formula becoming;
P(A/B) = P(AnB)/P(B)
P(B)*P(A/B) = P(AnB)
So, inserting our probabilities into this equation gives:
0.6*0.8 = 0.48
Answer:
The actual unemployment rate was higher during the recession of 1990−1991, while cyclical unemployment was higher in 2001.
Explanation:
Given data in the question
In the year 1990-1991
The natural rate of unemployment = 5.9%
The rate of the actual unemployment = 7.0%
In the year 2001
The natural rate of unemployment = 4.8%
The actual unemployment rate = 6.0%
As we can see that
The actual unemployment is high in the year 1990-1991 i.e 7.0% as compare to the year 2001 i.e 6.0%
While the cyclical unemployment rate is high in 2001 i.e 1.2% (6.0 - 4.8%) as compare to the year 1990-1191 i.e 1.1% (7.0% - 5.9%)
Answer:
The scarcity is the key problem that the economics are trying to find an answer to and try to mitigate by making the resources more productive.
The scarcity arises because of 2 main factors,
- The human wants are Unlimited
- The resources available to satisfy these wants are Limited
In theory, if we need to "eliminate" scarcity complete we should either Limit our Needs or find an Unlimited source of resources we require.
However, these are not practical solutions.
So because of this, economics try to utilize technology and other factors to harness the full potential of resources and to use them optimally.
