Answer:
Kindly check explanation
Step-by-step explanation:
Given the data:
Num shopping centers (X) :
630
370
616
700
430
558
1200
2976
Sales (Y) :
15.5
7.5
13.9
18.7
8.2
13.2
23.0
87.3
The regression equation obtained using the online regression calculator is :
y = 0.03025X - 4.87014
2.) The slope value, for every unit change in number of shopping centers, the number of sales increases by 0.03025
3.)
The Coefficient of determination (R²) as obtained by the R² value calculator is : 0.9823
4.)
About 98% of variation in number of sales is explained by the regression line
5.)
Correlation Coefficient = 0.9911
H0 : p ≥ 0.99
H1 : p < 0.99

Answer:
H y +268 = 12(x +20)
Step-by-step explanation:
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
The first point in the table is (x, y) = (-20, -268), so the equation with these filled in is ...
y -(-268) = m(x -(-20))
y +268 = m(x +20) . . . . . . matches F or H
We can see that the values of y change by a lot more than the values of x. That means the slope is a lot more than 1. This observation eliminates choice F, so we are left with ...
H. y +268 = 12(x +20)
0 is the answer to the question.
12.38 in expanded form is write like:-
10 + 2 + .3 + .08 = 12.38
To
write a number in expanded form just means to write the number in a
layout and when you add it up it will become the number you needed to
write in expanded form.
So, 12.38 written in expanded form is:- 10 + 2 + .3 + 0.8
Hope i helped
I would answer but i can not see what it says.... Sorry
