Answer:
f(x)=208^0.3x
Step-by-step explanation:
Think of this as a graph. You start out with 208 caribou, which is your y intercept, as it is there when the growth is 0.
The generic formula fr an exponential equation is a^x.
A represents your initial value. In this case, its 208
x represents the growth. In this case, it's 0.3%.
Your equation should be f(x)=208^0.3x
Answer:
a) 0.6915; b) 2.83 years
Step-by-step explanation:
For part a,
The formula for a z score is
Our mean, μ, is 3.25 and our standard deviation, σ, is 0.5.
This gives us
z = (3-3.25)/0.5 = -0.25/0.5 = -0.5
Using a z table, we see that the area under the curve to the left of this is 0.3085. However we want the area to the right; this means we subtract from 1:
1-0.3085 = 0.6915
For part b,
We look in the cells of a z table to find the value closest to 20%, or 0.2000. This is 0.2005, which corresponds with a z score of -0.84:
-0.84 = (X-3.25)/0.5
Multiply both sides by 0.5:
0.5(-0.84) = ((X-3.25)/0.5)(0.5)
-0.42 = X-3.25
Add 3.25 to each side:
-0.42+3.25 = X-3.25+3.25
X = 2.83
The advertised life would be 2.83 years.

We could use the product rule of probabilities in solving this problem. For the first roll, the probability of getting an even number is 3 / 6 = 1/2. For the second roll, the probability of getting a 6 is 1/6. Multiplying both is 1/2 * 1/6 = 1/12.
