Answer:
True if im not mistaken
Step-by-step explanation:
Y= 12 -3x so if you take x as 0 y=12 x=1 y=9 x=2 y=6
(0, 12) (1,9), (2,6) are on the graph
Answer:
y = -4/5x + 14/5
Step-by-step explanation:
Point (6,-2) and (-4,6)
Slope = (6- - 2) / (-4-6) = 8 / -10 = - 4/5
(The slope is negative because La línea is going downhill. Uphill is positive)
You can also find the slope in the graph: rise/run.
y-intersect (any point)
Point (6, -2) (any point)
y-Intercept: -2 - (-4/5)(6) = -2 + 24/5 = 14/5
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.
A line perpendicular to y = -2x + 5 will have an equation in the form of:
y = (1/2)x + b
Since the graph must intersect (-2,9), we plug in this point to solve for b.
9 = (1/2)*(-2) + b
9 = -1 + b
10 = b
So the equation is:
y = (1/2)x + 10
The answer is A.
