Answer:
The ratio of the number of bulbs tested to defective bulbs is always 14 to 1.
<u><em>What is the unitary method?</em></u>
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
We generally expect industrial processes to produce defects at about the same rate, the proportion of the defective product is generally considered to be a remain constant.
Here, the proportion of defective bulbs is:
1/14 = 2/28 = 6/84
So, it will be 24/336.
The ratio of the number of bulbs tested to defective bulbs is expected to remain constant at about 14.

You should calculate like this: 595/5= $119
To determine the number of cubes he needs to fill the box (this is assuming the cubes are 1 in cubes, he would need to calculate the volume of the box. To find the volume he would multiply the length by the width by the height. This would be 5 in x 6 in x 7 in. The volume is 210 cubic inches, so he could fill it with 210 one inch cubes.
we do 2x-1/y=w+2/2z
2x-1/y we multiple each side y
2x-1/y×y=2x-1
then w+2/2z
we said×2z×2z
then we got
w+2
later
2x-1=w+2=
then 1 become another side
which is 1+2=3
then
w=3-2x
I hope it's correct
