Answer:
0.36
Step-by-step explanation:
Given that:
Mean = 70
Standard deviation = 5.5
score (x) = 72
Formular for obtaining Standardized score (Zscore) :
Zscore = [score (x) - mean] / standard deviation
Hence,
Zscore = (72 - 70) / 5.5
Zscore = 2/ 5.5
= 0.3636363
Zscore = 0.36 ( 2 decimal place)
320 divided by 10 is equal to 32. So, the bakers can make 32 bagels per hour. Then, you do 32 times 18 which is equal to 576 bagels in 18 hours.
