Answer:
<h2>slope = -2</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>y = mx + b</em>
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
<em />
We have the equation:
<em>y = -2x + 6</em>
therefore
<em>m = -2</em>
<em>b = 6</em>
Answer:
A.
.
Step-by-step explanation:
We are given that,
x = Number of days where 1 = Sun of 1st week and 7 = Sat of first week.
The corresponding table for the data is given by,
Days Day Number Number of Customers
Sun 1 115
Mon 2 77
Tue 3 60
Wed 4 51
Thur 5 68
Fri 6 86
Sat 7 120
The general form of the regression model is
.
Using the sinusoidal regression calculator, we get that,
a = 33.690
b = 0.887
c = 1.337
d = 81.684
That is, the sine regression model is
.
Thus, option A is the sine regression model for the given data.
