Answer:
60
Step-by-step explanation:
Use r-combinations.
Treat it as though u are filling in 6 slots
_ _ _ _ _ _
1. First fill in the 7s, there are three of them and 6 ways to do so
so (6 Choose 3)
2. then fill in the 2s, now with the 3 slots taken up by the 7, 3 slots left.
So its (3 Choose 2).
3. and only 1 way to fill in the 8. (1 choose 1)
By multiplicative rule,
(6C3) * (3C2) * (1C1) = 60
As with simple linear regression, we desire the residuals to:
- Have constant variance.
- Have a mean close to 0.
<h3>What is a simple linear regression?</h3>
It should be noted that a simple linear regression simply means a model that describes the relationship between a dependent variable and an independent variable.
In this case, as with simple linear regression, we desire the residuals to have constant variance and have a mean close to 0.

11 and 12 are called bases of the exponents and only when bases are the same can the exponents be added.
x²• x³=x^(2+3)=x^5
When bases are not the same but the exponents are, you multiply bases and keep same exponent.
12³•11³=(12•11)³=132³
