Answer:
T, F, F, F
Step-by-step explanation:
Sliding the figure to the left 5 times only changes vertex positions, not the shape (making the third false), the sides (making the second and fourth false), or the angle (making the first true)

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
 and standard deviation  , the zscore of a measure X is given by
, 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
 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.
