Answer:
The reasoning is correct. The ratio of number of bulbs tested to defective bulbs is always 14 to 1.
Step-by-step explanation:
We generally expect industrial processes to produce defects at about the same rate, meaning the proportion of defective product is generally considered to be a constant. Here, the proportion of defective bulbs is ...
... 1/14 = 2/28 = 6/84
so we expect it will be also 24/336. That is, the ratio of the number of bulbs tested to defective bulbs is expected to remain constant at about 14.

Answer:
148cm^2
Step-by-step explanation:
The formula for surface area of a rectangular prism is 2(hl)+2(hw)+2(wl).
we just plug in the values.
2(6 x 5) + 2(6 x 4) + 2(4 x 5)
= 2(30) + 2(24) + 2(20) then simplify
= 60 + 48 + 40
= 148
1,400 is 1,427 rounded to the nearest hundred because everything in front of what you have to round to stays the same and the number next to 4 is a 2 so you let it rest and stay a 4 and everything after that becomes a 0
