What is the prime factorization of 65

Prime factorization of 65 is

Solution:

Need to find the prime factorization of 65.

Prime factorization is finding all the prime factors of 65.

Method is to take prime number one by one . check whether the given number is divisible by the  prime number till you get all the prime factors  of given number.

In our case number is 65 . since given number 65 is not divisible by first two prime number that are 2 and 3 , divide 65 by third prime number = 5  

That means 65 =

Now if you see, both factors that are 5 and 13 are prime numbers.  

So prime factorization of 65 is

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

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.
