A. Mr. Babe made a commission of $14.85
B. He makes $15.75 per hour after the raise.
Step-by-step explanation:
A. While he worked there, Mr. Babe earned 3% on how much he sells. If he sold $495 couch, how much commission did he make?
Worth of sold couch = $495
Commission = 3%
Amount of commission = 3% of total worth sold
Amount of commission =
Amount of commission =
Mr. Babe made a commission of $14.85
B. On top of his commission, Mr. Babe made $15 per hour. He eventually got a raise with an increase of 5% per hour. After the raise, how much did he make per hour?
Amount earned per hour = $15
Increase = 5%
As the increment is on per hour amount, therefore,
Amount of increase = 5% of per hour amount
Amount of increase =
New amount per hour = Per hour amount + amount of increase
New amount per hour = 15+0.75 = $15.75
He makes $15.75 per hour after the raise.

The z-score of the considered newborn having 4,000 g weight is
If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z score.
If we have
(X is following normal distribution with mean and standard deviation
)
then it can be converted to standard normal distribution as
(Know the fact that in continuous distribution, probability of a single point is 0, so we can write
Also, know that if we look for Z = z in z tables, the p value we get is
For the considered case, the statement in the problem is missing the mean weight of the newborn and standard deviation of the data set of weights of newborn.
Thus, for them, we can consider variables in place of their actual values.
Let we have:
- X = weights of newborns for some considered system (in grams)
= mean weight of newborns (in grams)
= standard deviation of the data set of weights of newborns
Then, the z-score for X = 4000 is
Thus, the z-score of the considered newborn having 4,000 g weight is
