Answer:
15.7 years
Step-by-step explanation:
we know that
The deforestation is a exponential function of the form
where
y ----> the number of trees still remaining in the forest
x ----> the number of years
a is the initial value (a=500,000 threes)
b is the base
b=100%-4.7%=95.3%=95.3/100=0.953
substitute
The linear equation of planting threes in the region is equal to
using a graphing tool
Solve the system of equations
The intersection point is (15.7,235,110)
see the attached figure
therefore
For x=15.7 years
The number of trees they have planted will be equal to the number of trees still remaining in the forest
When you first pick a ticket, there are 2 winning tickets and 40 total tickets. This means that there is a 2/40 chance of your ticket being a winning one. This fraction can be reduced to 1/20.
After this, there will be 1 winning ticket left and 39 total tickets. There is a 1/39 chance of the next ticket being a winning one. We multiply these two fractions together to get our answer. 1/20 * 1/39 = 1/780, so there is a 1/780 chance of having 2 winning tickets.
Answer:
Step-by-step explanation:
A function that represents the number of minutes it takes to deliver x newspapers is y = 12 + 2x/3.
<h3>What is the function?</h3>
The function that represents the number of minutes it takes to deliver x newspapers is: total minutes = time it takes to orgainse the newspapers + time it takes to deliver x newspapers
Time it takes to orgainse the newspapers = 12 minutes
Time it takes to deliver x newspapers = 2x / 3
y = 12 + 2x/3
