Answer:
A=$1.11
B=$19.61
Step-by-step explanation:
Convert 6% to decimal so move the decimal 2 places to the left so you get 0.06. You multiply 0.06 by 18.50 and you get 1.11.(Step A)
Then you add 18.50 to 1.11 to get $19.61.

Answer:
1,3,6,8,9
Step-by-step explanation:
Answer:
And using a calculator, excel or the normal standard table we have that:
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the scores of a population, and for this case we know the distribution for X is given by:
Where
and
Since the distribution for X is normal then we know that the distribution for the sample mean
is given by:
We can find the individual probability like this:
And using a calculator, excel or the normal standard table we have that:
