Helena asked five drama club members in her homeroom how many tickets they had sold. The mean number of tickets sold was 16.

Then she took ten random samples from the entire drama club of 75 students. The mean number of tickets sold was 22.5.

Compare the means. Is one sample a better representation? Explain why or why not.

alright well the answers to your question is

2xy/9 hope this have a nice day : )

step-by-step explanation:

the answer is 2/54

step-by-step explanation:

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
