2 + 3 = 5 Add whole numbers
10/12 + 3/12 = 13/12
13/12 = 1 and 1/12
5 + 1 = 6
6 + 1/12 = 6 and 1/12
Answer: 6 and 1/12
Least-squares regression is used to find the equation of best fit of a linear model
The equation of the least-squares regression line for predicting GPA from the number of absences is
The given parameters are:
The equation of the least-squares regression line is represented as:
Where:
So, we have:
Substitute values for a and b in
So, we have:
Approximate
Hence, the equation of the least-squares regression line for predicting GPA from the number of absences is

Answer: The answer would be "C"
Step-by-step explanation:
2000 x .0035 = 70
490/70 = 7
Answer:
y = (-1)*2^(x + 1)
Step-by-step explanation:
This one is not a line. It is something raised to a power. In addition, there is an ugly minus sign somewhere.
First of all, every answer is some sort of power of 2. All of them are 2^x but we don't exactly know how x words. It is not a simple y = 2^x because the first one is - 4 not - 2.
So there is an extra power somehow.
Try
y = 2^(x + 1) That looks promising
x = 1
y = 2^(1 + 1)
y = 2^2
y = 4
===============
Try another one
x = 2
y = 2^(2 + 1)
y = 2^3
y = 8
==============
I think you'll find that the other two are well behaved. and come to the answer (except for the minus) as they should.
What about that minus.
y = (-1)*2^(x + 1) should give a minus y value for any term.
Answer:
Step-by-step explanation:
She has a budget of $150, which means that she can spend no more than that amount. Therefore, use the less than or equal to symbol: ≤
Each folder is $2.15, so you are going to multiply: 2.15 × f
Each notebook is $4.60, so you will multiply: 4.6 × n
You want to know how many notebooks and folders you can buy for $150, so add the notebooks and folders.
Make the equation:
