22 dollars, because if we add 10 onto that grand total then divide we get what it would cost one 1 day which seems to be 22 dollars
Answer:
768,543, and 8,451
Step-by-step explanation:
The 8 is in the hundreds place, so when multiplied by 10 it would be in the thousands place.
SOLUTION
The mean is 4min
standard deviation is 1min
the z score is
where
then we have
The probability the call lasted less than 3 min will be
Therefore, the probability that (z < -1 ) is
[tex]\begin{gathered} Pr(z<-1)=Pr(0
Hence, the percentage of the calls that lasted less than 3 min is 16%
The answer will be: 1,000,000 if you round to the nearest hundred thousands. Hope it helps! :D
