If u={a,b,c,d}and p={b,d,e}find p(bar at the top)
san4es73 [151]

Answer:

{a , c}

Step-by-step explanation:

first find u intersection p

n(U n P ) = {a , b , c , d} n {b , d , e}

={d , b}

intersection means element or values which lies in both the sets

now to find p complement

note : p( bar at the top ) is read as p complement

p complement = n(U) - n(U n P)

={a , b , c , d} - {d , b}

={a , c}

n(U) -n(U n P) means the elements which is only in n(U ) but not in n(U n P)

How many two-digit numbers are there in which the tens digit is greater than<br> the ones digit?
Dovator [93]

there are 46 2-digit numbers in which the tens digit is greater than the ones digit.

<h3>How many 2-digit numbers are there in which the tens digit is larger than the ones digit?</h3>

A 2-digit number is written as:

a*10 + b

Where a and b are single-digit numbers.

Tens digit and ones digit refers to place values:

a is the tens digit, and b is the ones digit. The numbers with a larger tens digit than the ones digit are:

98, 97, 96, 95, 94, 93, 92, 91, 90, 87, 86, 85, 84, 83, 82, 81, 80, 76, 75, 75, 74, 73, 72, 71, 70, 65, 64, 63, 62, 61, 60, 54, 53, 52, 51, 50, 43, 42, 41, 40, 32, 31, 30, 21, 20, 10.

We can see that there are 46 numbers in that list, so we conclude that there are 46 2-digit numbers in which the tens digit is greater than the ones digit.
