Answer:
Step-by-step explanation:
Assuming the following data
X: 44, 44, 11, 11, 55
Y: 66, 55, -1, -3, 88
We want to find a linear model
For this case we need to calculate the slope with the following formula:
Where:
So we can find the sums like this:
With these we can find the sums:
And the slope would be:
Nowe we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
Answer:
y =
Step-by-step explanation:
In order to get <em>y</em> by itself, we need to pull <em>y</em> out of 1 and <em>m </em>on the right side.
b = y(1 - m) since y(1 - m) is the same as y - my.
Once we have pulled <em>y</em> out of 1 and m, we can divide both sides by 1 - m
=
We can cancel out the 1 - m on the right side since (1 - m) / (1 - m) = 1
Finally we get our answer:
= y
This is the same as y =
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Which is less, 2/5 or 4/5?
I'll use a cake for explanation.
Suppose we have a cake, and one of your companions, Mary, is hungry, so she takes 2/5 of one cake. Then, your other friend, Bella, takes 4/5 of the cake.
Then you compare the cakes. Who has less, Mary or Bella?
That's right, Mary.
So 2/5 is less than 4/5.
