Answer:
0.0139
Explanation:
Given that:
The number of sample (n) = 21
The sample distribution has mean (μ) and a standard deviation of σ/√n
The z score is given as (x - mean)/ standard deviation
x = 94.8 wpm, let us assume that σ = 10 and μ = 90
Therefore: z = (x - μ) / (σ/√n) = (94.8 - 90) / (10/√21) = 2.2
To calculate the probability using Z table:
P(X>94.8) = P(Z>94.8) = 1 - P(Z<94.8) = 1 - 0.9861 = 0.0139
The probability is low that is less than 0.05, the program is more effective than the old one.
Answer:
The eccentricity, denoted by e, is defined as that fraction of an ellipse size which causes the focus to move away from the center. When an ellipse has an eccentricity of zero, this means that the focus and the center are in one same place. Thus the eccentricity of the secondary focus located at the sun is zero when located at the sun. Thus with an eccentricity of zero, the focus and center will be at same place therefore making the shape of the orbit to be a perfect circle.

Explanation:
GDP per capita, income per capita or income per capita is an economic indicator that measures the relationship between the level of income of a country and its population. For this, the Gross Domestic Product (GDP) of said territory is divided by the number of inhabitants.
The use of per capita income as an indicator of wealth or economic stability of a territory makes sense because through its calculation national income is interrelated (through GDP in a specific period) and the inhabitants of this place.
The objective of GDP per capita is to obtain data that somehow shows the level of wealth or well-being of that territory at a given time. It is often used as a measure of comparison between different countries, to show differences in economic conditions.
People often have different expectations. If people have rational expectations, the sacrifice ratio could be much smaller than suggested by the short-run Phillips curve is a false a statement.
- The sacrifice ratio is said to be smaller than suggested by former estimates. The short-run phillips curve will ten to shift downward and the economy would reach low inflation very fast.
Rational expectations is known to be an economic theory. It simply states that when making decisions, individual agents will capitalize their decisions on the information that is best and available and they also learn from past trends.

Answer:
e) $93,097
Explanation:
Interest for 1st year = $100,000*8%
Interest for 1st year =$8,000
Principal repayment for 1st year = $14,903 - $8,000
Principal repayment for 1st year = $6,903
Principal balance on January 1,Year 2 = $100,000 - $6,903
Principal balance on January 1,Year 2 = $93,097
