Answer:
121
Step-by-step explanation:
Given data as per the question
Standard deviation = = 840
Margin of error = E = 150
Confidence level = c = 95%
For 95% confidence, z = 1.96
based on the above information, the minimum number of clients surveyed by the travel agent is
= 120.47
= 121
hence, the 121 number of clients to be surveyed
Therefore we applied the above formula to determine the minimum number of clients

The slope-intercept form: y = mx + b
m-the slope
8x + y - z
You can tell because each term is separated by an operator such as +, -, *, or /
