Abag holds 26 tiles, each marked with a different letter. what is the probability that one tile chosen at random is not a vowel?

21/26 percent chance and if you count Y as a vowel 20/26

21/26

Step-by-step explanation:

There are 5 vowels in the  26 letters of the alphabet.

So the total of non-vowels = 26-5 = 21.

Therefore the probability of getting  a non vowel = 21/26

what are the things "represented below"?

step-by-step explanation:

nobody can if you dont give the choices

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
