Answer:
In 2050 fish population is 27000
Step-by-step explanation:
Exponential change can be modeled by,
Where is the initial value of 750,
is the rate of change. It is greater then 1 when there is growth and less then 1 when there is decay. and
is the number of time periods.
The rate of change in percentage is 8.3%
That means, after 1 year fish will become 108.3 for 100 fish.
Then
Difference of years is,
Then,
So, the fish population in 2050 is 27000
Answer:
0%
Step-by-step explanation:
We have the following information:
mean (m) = 208 days
standard deviation (s) = 15 days
We have that the z value would be:
z = (x - m) / sd
replacing we have:
z = (308 - 208) / 15
z = 6.66
However,
P (x> 308) = 1 - (x <308)
P (x> 308) = 1 - (z <6.66)
if we look for this value of z in the table we assume that it is 1, since the table reaches 3 and the value is 1. Therefore:
P (x> 308) = 1 - 1
P (x> 308) = 0
Which means that the probability is 0%, therefore it is a very unusual pregnancy.
The best-fitting regression model for the scatter plot is exponential curve , Option C is the right answer.
The missing graph is attached with the answer.
<h3>What is an exponential graph ?</h3>An exponential graph is given by y = aˣ , the graph for an exponential growth is also attached with the answer,
From the graph given in the question it can be concluded that it is not linear , not quadratic and it is not true that it doesn't have a pattern , It is an exponential growth graph, Therefore Option C is the right answer.
