Answer:
Country North has the comparative advantage in the production of tractor
Step-by-step explanation:
The principle of comparative advantage states that a country should specialize in the production of goods in which it have comparative cost advantage over other nations. i.e A country should focus on the production of the goods in which it has a lower opportunity cost in producing than someone else.
The question given shows that Country North has a lower opportunity cost (which is 21 watches) if it produces 3 tractors compared to country south which has an opportunity cost of 100 watches when it produces 5 tractors.
Hence, we can say that country North has a comparative advantage in the production of Tractors over country south because its opportunity cost when its produces tractors is lower than that of the country south
Answer:
C. 2 times as long
Step-by-step explanation
8 times 10^-7 written in standard form is 0.0000008
4 times 10^-7 written in standard form is 0.0000004
divide both of them:
=2
Answers : A and D
Step - by - step explanation :
tip : when finding constant of proportionality it's always Y divided by X
A = what is 22.5 divided by 3 ? 7.5 ( now multiply 7.5 by the next X [ 4 ] )
what is 7.5 x 4 ? 30 ( and since on the graph it also says 30 then you can assume this one has a proportional relationship )
B = what is 12 divided by 3 ? 4 ( now multiply 4 by the next X [ 5 ] )
what is 4 x 5 ? 20 ( and because the graph says 25 then you know it's NOT a proportional relationship )
C = what is 8.5 divided by 2 ? 4.25 ( now multiply 4.25 by the next X [ 5 ] )
what is 4.25 x 5 ? 21.25 ( and because the graph says 22.5 then you know it's NOT a proportional relationship )
D = what is 10 divided by 2 ? 5 ( now multiply 5 by the next X [ 3 ] )
what is 5 x 3 ? 15 ( and since on the graph it also says 15 then you can assume this one has a proportional relationship )
( sorry it took me so long to write this )
Answer:
Step-by-step explanation: start at -39 degrees. You need to find how many degrees is between -39 and 10 degrees.
+39+10= 49 degrees risen
To solve for the confidence interval for the population
mean mu, we can use the formula:
Confidence interval = x ± z * s / sqrt (n)
where x is the sample mean, s is the standard deviation,
and n is the sample size
At 95% confidence level, the value of z is equivalent to:
z = 1.96
Therefore substituting the given values into the
equation:
Confidence interval = 3 ± 1.96 * 5.8 / sqrt (51)
Confidence interval = 3 ± 1.59
Confidence interval = 1.41, 4.59
Therefore the population mean mu has an approximate range
or confidence interval from 1.41 kg to 4.59 kg.
