Explanation

Using the information that x = 12 when y = 4, we can find the value of k, because y = k/x

becomes 4 = k/12.

Solving this for k,

we get k = 3

When x = 18

y = k/x becomes

y = 3/ 18

This simplifies to y = 6

Explanation

A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. 

For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1

Prime numbers: 2,3,5,...99

Explanation

Percentage of the applicant to a program were rejected = 80%

Percentage of the applicant to a program who were accepted would be =100%-80%                                                                    =20%

So, The ratio of the number accepted to the number rejected is given by = 20: 80

= 1 : 4

Explanation

Step 1 of 2 :

Write down the arithmetic mean and total count of numbers

Here it is given that the arithmetic mean of six numbers is 4.5

Arithmetic mean = 4.5

Total count of numbers = 6

Step 2 of 2 :

Calculate the total sum of six numbers

The total sum of six numbers

= Arithmetic mean × Total count of numbers

= 4.5 × 6

= 27

Explanation

Explanation

the required number is :

15 a = > 15( 5 ) = 75.

Thus, the number satisfying the given equation is 75
