Answer:
The value of X is 3.6 minutes.
Step-by-step explanation:
We assume that the time on hold follows a normal distribution with
To calculate how many minutes the 1.5% of the customers are put on hold, we have to determine the z-value for this probability (P=0.015).
Looking in a z-table, the z value is 2.17:
This can be translated to our distribution as:
The value of X is 3.6 minutes.
Answer:
76
Step-by-step explanation:
100% = 120
1/5 of 100% = 20%
20% = 120÷100×20
= 24
100-24= 76
Answer: x > 5
Step-by-step explanation:
simplify and solve. see photo of work for further explanation.
Divide 12.32 by 7 which is 1.76 so multiply that by 11 which is 19.36
