Week 1 : 1 customer tells 3 friends

Week 2: 3 new customers tell 9 friends

Week 3: 9 new customers tell 27 friends

If w represents number of weeks, then (C) represents the model appropriately. Let's see how:

Putting w = 1 , 2 and 3 in each of the options

(A) 3w: 3 for week 1, 6 for week 2, 9 for week 3 ⇒ INCORRECT

(B) w^3: 1 for week 1, 8 for week 2, 27 for week 3 ⇒ INCORRECT

(C) 3^w: 3 for week 1, 9 for week 2, 27 for week 3 ⇒ CORRECT

(D) 3w^3: 3 for week 1, 24 for week 2, 81 for week 3 ⇒ INCORRECT

Hence, the answer is (C)

Answer:  Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Number of product in first week = 3

Number of product in second week = 9

Number of product in third week = 27

Let the number of week be 'w'.

So, algebraic expression of the number of product in w weeks would be

3^w

Hence, Option 'c' is correct.

Select a counter-example that makes the conclusion false.
Leya [2.2K]

The statement is False.

For this, it is enough to show a case in which the subtraction of two positive numbers is negative.

For this, we must choose two numbers.

Suppose we want to subtract the following numbers:

Number 1: 5

Number 2: 10

Subtracting both numbers we have:

5 - 10 = -5

We observe that the result is negative. Therefore, the given conclusion is false.

Answer:

Counterexample:

5-10 = -5
