Answer:
$15,360
Step-by-step explanation:
To find the retail price, multiply 12,800 by 1.2
12,800(1.2)
= 15,360
So, the retail price is $15,360
Answer:
Equation of line best fits the scatter plot is y =
Step-by-step explanation:
Let the equation of line be y = mx + c
where m = slope of line and c is the intercept on y -axis
from the graph intercept on y-axis is 108
and the slope of line is given by m =
where (
) and (
) is the points on line
let, points be (4,96) and (18,36)
on calculating this m =
= 
Therefore equation of line best fits the scatter plot is y =
Answer:
Option D is correct
Step-by-step explanation:
From the question, we have:



Required
The tree diagram
The selection process is as follows:

-- i.e. we write sack 2 as a subset of 1
-- i.e. we write sack 3 as a subset of 2
<em>The only tree diagram that illustrates this is: option D</em>
q= 6
r= 7
work--
Multiply 1st column by -2:
-30q+8r=-124
5q+8r=86
Subtract 2nd column from the first column:
-35q= -210
Solve for q:
q=6
Subtract q=6 by any of the two equations, so:
-30q+8r=-124
-30*6+8r=-124
Solve for r:
r=7
