The equation that models the exponential decline is y = 46348587109809610(0.9861)ˣ if the population over the past 20 years is provided.
<h3>What is the line of best fit?</h3>A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
Let's suppose the equation that models the exponential decline is:
From the data given, we can calculate the value of a and b:
a = 46348587109809610
b = 0.9861
y = 46348587109809610(0.9861)ˣ
Thus, the equation that models the exponential decline is y = 46348587109809610(0.9861)ˣ if the population over the past 20 years is provided.

Answer:
The number of the cups of uncooked rice is 3 cups
The number of the cups of water is cups
Step-by-step explanation:
* Let us read the recipe of Nasi Gorang
- 2 cups of uncooked rice need cups of water to
make cups of cooked rice
- Joseph needs cups of cooked rice
- We need to know how many cups of uncooked rice Joshep needs
for this recipe and how much water should be added
* We can solve this problem by using the ratio method
⇒ uncooked cups : water cups : cooked cups
⇒ 2 : :
⇒ x : y :
- By using cross multiplication
∵ x ( ) = 2 (
)
∵ =
∵ =
∴ x ( ) = 2 (
)
∴ x = 13
- Divide both sides by
∴ x = 3
∴ The number of the cups of uncooked rice is 3 cups
- By using cross multiplication
∵ y ( ) = (
)(
)
∵ =
∵ =
∵ =
∴ y = (
)(
)
∴ y =
- Divide both sides by
∴ y =
∴ The number of the cups of water is cups
