Answer: Total Surface Area

Step-by-step explanation:

Hi, to calculate the amount of cardboard needed to create a cereal box we have to calculate the total surface area.

The volume is used to calculate the amount of cereal that the box can contain, and the lateral surface area will not include all the cardboard needed for the complete box.

Feel free to ask for more if needed or if you did not understand something.

The coefficient of determination of a set of data points is 0.93 and the slope of the regression line is -5.26. Determine the li

skad [1K]

Answer:

- 0.964

Step-by-step explanation:

Given that Coefficient of determination (R^2) = 0.93

Slope of regression line = - 5.26

The linear correlation Coefficient =?

The Coefficient of determination (R^2) is used to obtain the proportion of explained variance of the regression line. It is the square of the linear correlation Coefficient (R).

Hence. To obtain the linear correlation Coefficient (R) from the Coefficient of determination (R^2); we take the square root of R^2

Therefore,

R = √R^2

R = √0.93

R = 0.9643650

R = 0.964

However, since the value of the slope is negative, this depicts a negative relationship between the variables, hence R will also be negative ;

Therefore, R = - 0.964

What does the constant 0.9955 reveal about the rate of change of the quantity?

cricket20 [7]

The model given is:

$f(t)=290(0.9955)^{60t}$

The term in the parentheses represents the change of rate of the model. If the number is the parentheses is less than 1, we call it <em>exponential decay</em>.

If the number in parentheses is bigger than 1, we call it exponential growth.

In this case, the correct option is "decaying"

The number in parentheses let's call it R, is:
