Answer:
The coefficient of correlation does not change.
Step-by-step explanation:
We are given the following in the question:
The daily intake food is measured in ounces.
The body weight is measured in pounds.
Correlation between food intake and body weight = 0.80
Properties of correlation:
- Correlation is a technique that help us to find or define a relationship between two variables.
- It is a measure of linear relationship between two quantities.
- The correlation between two variables is not effected by the units of the variable.
- Even if the variable of the explanatory variable or the response variable changes, the correlation does not not change and remains same.
Conclusion:
A shift in units from ounces to grams and from pounds to kilogram does not change the value of coefficient of correlation.
It would be 200+9+0.1+0.006.
Answer:
- 2 and 3 are the the growth rates parameter for x and y respectively
- 16 and 20 are the carrying capacities for x and y respectively
- 2 and 7 measures the benefit to x and y of the interaction of the two species.
The species compete each other.
Step-by-step explanation:
When we have a population model for two species as we have here, the differential equations looks like this:


Here:
a and d are the the growth rates parameter for x and y respectively
N and M are the carrying capacities for x and y respectively
c and f measures the benefit to x and y of the interaction of the two species.
So in our case we have:


Therefore:
- 2 and 3 are the the growth rates parameter for x and y respectively
- 16 and 20 are the carrying capacities for x and y respectively
- 2 and 7 measures the benefit to x and y of the interaction of the two species.
The term xy determine the if the species are cooperating of competing, so in this case have negative xy term in the second equation, it means the presence of either species decreases the rate of change of the other, so the species compete each other.
I hope it helps you!
For this case we can propose a rule of three:
bottle ------------>
minutes
x --------------------------------------> 1 minute
Where the variable "x" represents the number of bottles that can be filled in 1 minute.

Thus, William can fill
of a water bottle in 1 minute.
Answer:
William can fill
of a water bottle in 1 minute.
For this case what we should do is find an average value of the total prices for a trip to europe
We look for the average of the prices by means of the following expression:
P = (20.70 + 25) / (2)
P = 22.8 $
Answer:
the average price is $ 22.8
