Answer: The answer is 6.8 square meters
Step-by-step explanation:
area=25.5 meters
width=3.75 meters
if u want to find the length u should as said divide the area by widthim on school chromebook so i cant see the picture of what i just typed it should say 25.5 over 3.75
one more time:25.5/3.75=6.8
Also i do this in all of my answers now i do something from black panther movie.My favorite line from the movie THIS HOW I BE WHEN I BE ANSWERING QUESTIONS:Okoye:"just dont freeze" Chadwick/Prince(soon to be king;small spoiler) T'challa:What are u talking about..I never freeze. If u watch the movie and say what he said in that accent it will make u think of him and its so fun to do

Answer:
The standard deviation of number of hours worked per week for these workers is 3.91.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean and standard deviation
, the zscore of a measure X is given by
After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X. Subtracting 1 by the pvalue, we This p-value is the probability that the value of the measure is greater than X.
In this problem we have that:
The average number of hours worked per week is 43.4, so .
Suppose 12% of these workers work more than 48 hours. Based on this percentage, what is the standard deviation of number of hours worked per week for these workers.
This means that the Z score of has a pvalue of 0.88. This is Z between 1.17 and 1.18. So we use
.
The standard deviation of number of hours worked per week for these workers is 3.91.
