If you would like to know what is the amount of money Yul should leave for the tip, you can calculate this using the following steps:
20% of $14.50 = 20% * 14.50 = 20/100 * 14.50 = $2.9
Result: Yul should leave $2.9 for the tip.
20 less than (-20) a number (n) is more than (>) twice the same number (2n)
-20+n>2n
minus n both sides
-20>n
n<-20
Answer:
he is 8
Step-by-step explanation:
Answer:
20.27
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean
and standard deviation
, the sample means with size n of at least 30 can be approximated to a normal distribution with mean
and standard deviation 
Using the Central Limit Theorem for Means, what is the standard deviation for the sample mean distribution?
This is s when
. So

So the correct answer is:
20.27
