Consider the following statement. If n is divisible by 6, then n is divisible by 2 and n is divisible by 3. Negation

a. n is divisible by 6 and either n is not divisible by 2 or n is not divisible by 3.
b. If n is not divisible by 2 or n is not divisible by 3, then n is not divisible by 6.
c. If n is divisible by 2 and n is divisible by 3, then n is divisible by 6.
d. If n is not divisible by 6, then n is not divisible by 2 or n is not divisible by 3.
e. If n is not divisible by 6, then n is divisible by 2 and n is divisible by 3.

b. If n is not divisible by 2 or n is not divisible by 3, then n is not divisible by 6.

Step-by-step explanation:

Division by Six

A number is divisible by six if it is divisible by both 2 and 3.

Negation:

If the number is not divisible by either 2 or 3, it is not by 6. So the answer is given by option b.

b.

Step-by-step explanation:

Division by Six

A number is divisible by six if it is divisible by both 2 and 3.

Negation:

If the number is not divisible by either 2 or 3, it is not by 6. So the answer is given by option b.

b is the final answer! : )

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
