Answer:

Step-by-step explanation:
Since the country wants to reduce the emission by the percentage each year, the function will be decaying function. The formula of decaying function will look like this

Where
E(t) = the number of emission after t years
E0= the number of initial emission= 40 million tons
r=rate of growth/decay = 35%= 0.35
t= time in years
If we put the number, the equation will be:

There is a one fifth chance of both so there is a 1/25 chance or .04 or 4% chance that this will happen
Answer:
B exactly one
Step-by-step explanation:
y=3x-12 = 3
y= x - (12-2x)
You would get $3 every year.
That is because since you got $18 in 6 years you would need to divide 6 into 18 and you would get $3 every year
1/2 because there are 36 red cards and 36 black cards in a standard deck, meaning half are red
