A. Find a power function that models the data below.
1 answer:
Using Visual inspection, the model which fits the data in the distribution better is the power function.
The power and linear functions can of the data can both be modeled using technology,
<u>Using Technology</u> :
The power function in the form which models the data is
The linear function in the form which models the data is
- Where A = intercept and B = slope
- From the model, correlation coefficient given by the power and linear models are 0.999 and 0.986 respectively.
- Hence, the power model is a better fit for the data than the linear model.
Therefore, Inspecting the models visually, the power function fits the data better as the points on the curve are closer to the regression line than on the linear model.

Answer:
The equation representing the problem is .
Mr. Patel used 5 bags of seeds.
Step-by-step explanation:
Given:
Number of times bird feeder refilled =24
Number of cups of seeds used each time = 6 cups
Number of seeds each bag holds = 32 cups.
We need to write the equation to represent the problem.
Solution.
Let the total number of bag of seed be 'x'.
First we will find the Total number of cups of seeds used.
Now we can say that;
Total number of cups of seeds used can be calculated by multiplying Number of times bird feeder refilled by Number of cups of seeds used each time.
framing in equation form we get;
Total number of cups of seeds used =
Now We know that;
1 bag holds = 32 cups
Total number of bags required =
So we can say that;
Total number of bags required is equal to Total number of cups of seeds used divided by number of seed hold by each bag.
framing in equation form we get;
Hence the equation representing the problem is .
On solving we get;
Since bags cannot be bought in half or in decimal value.
Hence we can say Mr. Patel used 5 bags of seeds.
