Answer:
Where's the rest of the question?
Step-by-step explanation:
You have to find out how much is it per Apple, to do that you divide 4 by $4.80 which is 0.8333...
Then you have to multiply that number by 2 which is 1.6666..
You multiply by 2 because if one pound is .83 and you need two more pounds to equal 6.
4.80+1.67=$6.47
Answer:
The equation of the line is
.
Step-by-step explanation:
According to Analytical Geometry, we know that any equation of the line can be determined by knowing two distinct points on Cartesian plane. From statement we get that:
(1)
(2)
By applying the definition of the equation of the line, we form this system of two linear equations with two variables:
(3)
(4)
By algebraic mean we get the following solution:
and 
And the equation of the line is
.

Answer:
- absolute error: 0.4 kg
- relative error: 6.1%
Step-by-step explanation:
The absolute error is the difference between the estimate and the actual weight:
7.0 kg -6.6 kg = 0.4 kg . . . . absolute error
__
The relative error is the ratio of the absolute error to the actual weight:
(0.4 kg)/(6.6 kg) × 100% = 6.060606...% ≈ 6.1% . . . . relative error
