What is the gcf of 21 30 anwhat is the gcf of 21 , 30 ,and 44?

Ymorist [56]

Find the prime factorization of each value.

21 is 7*3

30 is 3*10 which can be further broken down into 3*2*5

44 is 4*11 which can be further broken down into 2*2*11

What do they share in common?
21 and 30 each have a 3 in common.
Therefore the GCF(21, 30) = 3.

21 and 44 share a 2 in common.
But if we're looking at all three of them together, they share nothing in common.

The length of a text messaging conversation is normally distributed with a mean of 2 minutes and a standard deviation of 0.5 min

zhenek [66]

Answer:

Let x be a random variable representing the length of a text messaging conversation, then

P(x > 3) = 1 - P(x < 3) = 1 - P(z < (3 - 2)/0.5) = 1 - P(z < 2) = 1 - 0.97725 = 0.02275
