Answer:
a. yˆ=38,000+2500x
d. yˆ=38,000−1500x
Step-by-step explanation:
The least squares regression line for the population change of a small country has the following format:
In which a is the initial population and b is the number of habitants for which the population increases/decreases a year.
Let's see each case
a. yˆ=38,000+2500x
The population starts at 38000 and increases by 2500 a year. This is a feasible assumption.
b. yˆ=38,000−3500x
The population starts at 38000 and increases by 3500 a year. By the year 2015, the population will be negative. This is not a feasible assumption.
c. yˆ=−38,000+2500x
The population cannot start at a negative value. So this is not a feasible assumption.
d. yˆ=38,000−1500x
The population starts at 38000 and decreases by 1500 a year. This is a feasible assumption.
Answer:
22.2
Step-by-step explanation:
z/sinZ = y/siny
z/sin(51) = 18/sin(39)
z = sin(51) × 18/sin(39)
z = 22.22814882
