The expression consists of 4 terms, and each term contains 2 factors.
1) In this expression:
ab +cd + ef +gh
We can make the following definitions:
2) Factors are numbers or letters (in algebra) that we can use to multiply themselves and yields another number.
Terms can be defined as letters, numbers within an expression.
3) Hence, In this expression, we have then:
4 terms: ab, cd, ef, and gh
2 factors per term.
The expression consists of 4 terms, and each term contains 2 factors.

<h3>What is linear equation if two variables?</h3>
Linear equations with two variables are equations with one, zero, or infinitely numerous solutions where every of a two variables has the highest exponential order of 1.
Some key features regarding linear equation if two variables are-
- The two-variable linear equation has the conventional form ax + by + c = 0, where x and y are the variables.
- These solutions might also be expressed in pairs, such as (x, y).
- A graphical representation of a linear equation system in two variables involves two straight lines that can be intersecting, parallel, or coincident.
Now, according to the question;
The given equation is;
y = 55.8 + 2.79x
Calculate the value of y by substituting the value of x = 9.9.
y = 55.8 + 2.79×9.9
y = 83.42
Therefore, the best predicted value of y for x = 9.9 is 83.42.

The correct question is-
Eight pairs of data yield r = 0.708 and the regression equation y = 55.8 + 2.79x. Also, the mean y-value is 71.125. What is the best predicted value of y for x = 9.9?
Answer:
Second one: (1,2) (2,4) (3,6)
Step-by-step explanation:
