Answer: 36 months
Explanation:
The earth complete its orbit in 12 months
While the superior planet complete its orbit in 18 months
Therefore since they are moving in the same direction, both planet will meet at the point where the superior planet and earth completes x and x+1 number of orbits.
Where x is a constant that represents number of orbits.
The period y when they both complete x and x+1 orbit respectively are;
y= 18x and y = 12(x+1)
Equating the two equations, we have,
18x=12(x+1) = 12x + 12
18x-12x= 12
x= 12/6= 2
Since x= 2
y= 18x=18×2= 36months
y= 36 months
Goodluck...
Answer:
d. It involves the use of expert judgment to develop forecasts.
Explanation:
Forecasting :
Forecasting is the prediction technique of future demand by using past data.
The type of forecasting:
1 .Qualitative
In this technique ,expert gives own opinion regarding the future demand of any service or product.
2. Quantitative
In this technique
1 . The information can be quantified
2.Assume that future demand will follow a past demand curve.
3.. It can be used when past information about the variable being
forecast is available.
In the quantitative forecasting pert judgment does not use to develop forecasts.
Option d is the correct answer.
d. It involves the use of expert judgment to develop forecasts.
The surface temperature of the sun is 5,778k
Ideally, the drilling of fossil fuels from inner earth could lead to an accident from a oil spill which could cause a serious harm to the ocean environment and life.
<h3>What is oil drilling done?</h3>
A oil rig machine is used to drill the inner earth to derive crude oil for pertroleum, gas, bitumen, diesel etc.
However, this could harm the ocean because any incidence of oil spill from the drillng could cause a serious harm to the ocean environment and life.
