Answer:
Therefore we come to a conclusion that,
Gregory's Rectangle is in Area.
Step-by-step explanation:
Given:
Fiona draws a 24 centimeter rectangle.
Gregory draws a 24 square inch rectangle.
To Find:
Whose rectangle is in area = ?
Solution:
Rectangle has a dimension as
Length and Width which are in meters, centimeters, inches, feet, units, etc.
For Area
here units are getting Multiplied so it becomes
unit × unit = unit² = square units
m × m = m² =square meter
inch × inch = inch² =square inches
Hence Area is calculated in square units.
Therefore we come to a conclusion that,
Gregory's Rectangle is in Area.
Answer:
And using the normal standard table or excel we find the probability:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the avergae number of weeks an individual is unemployed of a population, and for this case we know the distribution for X is given by:
Where and
Since the distribution for X is normal then, the distribution for the sample mean is given by:
We select a sample of n =50 people. And we want to find the following probability
And using the normal standard table or excel we find the probability:
