im pretty sure because multiplying it makes more sense and also stop cheating on map testing
The equation of the line for the given data set of scatter plots will be y =- x. Since their Mean(M) is equal.
What is the Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
Given a data set of the number of text messages sent (x) and text messages received (y) by 10 students in a half hour.
so
x y
0 2
5 1
6 4
8 12
11 11
12 13
15 11
17 20
21 22
24 23
Where M of x = 11.9
also the M of y = 11.9
Sum of X = 119
Sum of Y = 119
Mean X = 11.9
Mean Y = 11.9
The sum of squares (SSX) = 504.9
The sum of products (SP) = 504.9
Regression Equation = ŷ = bX + a
b = SP/SSX = 504.9/504.9 = 1
a = MY - bMX = 11.9 - (1*11.9) = 0
ŷ = 1X - 0
Thus the equation of line best fit will be y = x.

Answer:
[tex]\frac{5}{12}[/tex]
Step-by-step explanation:
The given problem is a subtraction problem between fractions. The first step in a problem like this is to convert both fractions to a common denominator. In other words, multiply both the numerator and denominator of a fraction by the same value such that the denominator of one of the fractions is the same as the other fraction. The numerator of a fraction is the value over the fraction bar, whereas the denominator is the value under it. Multiplying any fraction by a number over itself is the same as multiplying it by one, thus, the equation will remain true, and be equivalent to the original expression.
[tex]\frac{13}{12}-\frac{2}{3}[/tex]
Convert to a common denominator,
[tex]\frac{13}{12}-(\frac{2}{3}*\frac{4}{4})[/tex]
[tex]\frac{13}{12}-\frac{8}{12}[/tex]
Now perform the subtraction, subtract one numerator from the other, remember, do no perfrom any more operations with the denominators,

If Jim works at Fire Fighting Equipment, has $32,874 in sales in one week,
and as paid a weekly salary of $452 plus a commission of .9% on sales
between $15,000 and $25,000, with 1.1% paid on sales in excess of
$25,000, no commission is paid on the first $15,000, what is his gross
earning?
Answers
Step-by-step explanation:
Giving the following information:
Sales= $32,874
Fixed salary= $452
Commission= 1.1% paid on sales in excess of $25,000.
To calculate the gross income, we need to use the following formula:
Gross income= 452 + y*x
y= percentage comission
x= sales
For $32,874 sales:
Gross income= 452 + 0.011*32,874
Gross income= $813.61
