The sequence 3, 5, 7 is a list of three prime numbers such that each pair of adjacent numbers in the list differ by two. Are the

andreev551 [17]

Answer:

Step-by-step explanation:

Suppose the numbers of interest are x, x+2, x+4. If we divide x by 3, its remainder will be one of 0, 1, or 2.

If x mod 3 = 0, then x will be a multiple of 3, so won't be prime (unless x=3).

If x mod 3 = 1, then x+2 will be a multiple of 3, so won't be prime.

if x mod 3 = 2, then x+4 will be a multiple of 3, so won't be prime.

Hence the only three sequential odd numbers that are prime are 3, 5, and 7. There are no more such "triplet primes."

_____

Consequently, the name "prime triplet" is given to sequences of primes that have the largest and smallest differ by 6. The middle one differs from one of the other two by 2. It is conjectured there are an infinite number of that sort of prime triplet.

There are 10 kids that want ice cream. Each one can choose between chocolate, vanilla or strawberry. You'll collect their choice

kolbaska11 [484]

Answer: There are 30 possible orders that can be made.

Step-by-step explanation:

Given : Number of kids that want ice cream= 10

Choices for flavors : chocolate, vanilla or strawberry.

i.e. Number of choices for flavors = 3

Then by Fundamental principle of counting , the number of possible orders can be =(Number of kids ) x (Choices for flavors)

$=10\times3=30$

Therefore , the total number of possible orders that can be made = 30.
