The following clues for writing a five digit number is

1.→The number consist of 3 different digits

2.→All digits are even numbers greater than zero.

The four even digit are =2,4,6,8

So,Total Number of five digit numbers in which three digits are Identical is

= First three places can be filled by any of the four numbers and then fourth and fifth place can be filled by any of the remaining three numbers in 3 and 2 ways.

=4 ×3×2

=24 Numbers

The numbers are

22246,22264,22284,22248,22268,22286,44426,44462,44468,44486,44482,44428,66624,66642,66648,66684,66682,66628,88824,88842,88864,88846,88826,88862.

Use the mapping to determine which of the following are elements of the range.

Vadim26 [7]

Answer:

The elements of the range are the birthdays.

Step-by-step explanation:

A function is a distinct sort of relation in which each element of the domain is combined with precisely one element in the range. A mapping displays how the elements are combined.

A mapping figure comprises of two parallel columns. The 1st column signifies the domain of a function, and the other column for its range.

Lines or arrows are drawn from domain to range, to signify the relation between any two elements.

A function denoted by the mapping, in which each element of the range is combined with accurately one element of the domain is called one-to-one mapping.

From the diagram provided it is clear that the function denoted by the mapping is an one-to-one mapping.

The elements of the range are:

Birthday : {January 5 , January 7 , February 24 , March 1 , April 7 , May 30 , July 20 , August 1 , November 13 , November 26 }

Thus, the elements of the range are the birthdays.

One of the two numbers is 2 less than twice the other number. If the

Alex Ar [27]

hey

let s note a and b the two numbers

we can write

(1) a = 2b - 2

(2) ab = 40

from (2) we can say for b different from 0 that

a = 40/b

replace it in (1)

40/b=2b-2

2(b-1)b = 40

b(b-1) = 20

$b^2-b-20 = 0$

5 is a trivial solution and as the product of the two solutions is -20 then the second solution is -4 therefore

$b^2-b-20 = 0$

<=> (b-5)(b+4) = 0

<=> b = 5 or b = -4

so we have

a= 40/b = 8 and b = 5

a = 40/b = -10 and b = -4

(8,5) and (-10.-4) are solutions

do not hesitate if you have any question

thanks

The experimental probability of a coin landing on heads is 7/12. If the coin landed on tails 30 times, find the number of tosses

nordsb [41]

Answer: 72 tosses

Explanation: If the probability of landing heads is 7/12, the probability of landing tails is 5/12. So then you do cross multiplication, where you multiply the 12 and the 30, equalling 360. Then divide that by 5, equalling 72.
