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.

Answer:
They are b and c.
Step-by-step explanation:
Let's simplify each expression:
a. b+2 (b+2b)
= b + 2b + 4b = 7b.
b. 3b + b = 4b.
c. 2(2b) = 2 * 2b = 4b.
Statistics is related to maths because we study, use and even consider statistic problems with reference to mathematics.
• It is mostly used to find the census, which is maths.
• It is used to find interest rates and other banking terms using statistics, which is again related to math.
• It is also used to find the average people living in a village or panchayat, which is also math.
Therefore I strongly believe that Statistics is Maths.
