Answer:
The net perfect number would be 28
Step-by-step explanation:
When you add up all the factors of 28 (other than 28) you get 28.
1 + 2 + 4 + 7 + 14 = 28
Answer: Probability P = 1/1716
Step-by-step explanation:
Definition
For permutation ( order is important)
nPr = n!/(n-r)!
Given;
Total number of members in the committee = 13
Total number of members to be selected = 3
Since order is important in this case.
The total number (Tt) of possible ways of selecting three executives from the committee members is given as
Tt = 13P3 (since order is important)
Tt = 13!/(13-3)!
Tt = 13!/10!
Tt = 1716
The probability P of randomly selecting the three members who currently hold the positions of chairman, ranking member, and treasurer and reassigning them to their current positions is equal to
P = number of favourable outcomes/ number of possible outcomes
Number of favourable outcomes = 1 (i.e 1×1×1 = 1) one option for each post.
Number of possible outcomes = Tt = 1716
P = 1/1716
Answer:
Mrs. Potts needs 72 feet of fencing.
Step-by-step explanation:
You find the perimeter of the rectangular garden, which is 24 yards. You then convert the yards to feet. There are 3 feet in a yard. You multiply 24 by 3 to get your final answer of 72 feet.
Let, the numbers = x, (x+2), (x+4)
x+x+2+x+4 = 63
3x+6=63
3x=57
x = 19
so, smallest number would be 19
