Answer:
The cost price of 12 boxes of pudding is $3.96
Step-by-step explanation:
Given as :
The quantity of pudding boxes = 3
The cost price for 3 boxes = $0.99
Again ,
The quantity of pudding boxes = 12
Let The cost price for 12 boxes = $x
Now, According to question
<u>Using Unitary method</u>
∵ The cost price of 3 boxes of pudding = $0.99
or,The cost price of 1 boxes of pudding = = $0.33
∴The cost price of 12 boxes of pudding =$0.33 × 12
I.e x =$3.96
So,The cost price of 12 boxes of pudding = x =$3.96
Hence,The cost price of 12 boxes of pudding is $3.96 Answer
The fraction by which the variance of the dependent variable is greater than the variance of the errors is known as R-squared. The correct option is C, 0.32.
<h3>What is R- Squared?</h3>The fraction by which the variance of the dependent variable is greater than the variance of the errors is known as R-squared.
It is called so because it is the square of the correlation between the dependent and independent variables, which is commonly denoted by “r” in a simple regression model.
fraction of the variability in data values = (coefficient of correlation)² = r²
For the given data, the correlation can be found as shown below. Therefore, the value of r is -0.56. Since we need the value of r², the value of r² is,
r² = (-0.56)²
r² = 0.3136 ≈ 0.32
Hence, the correct option is C, 0.32.
