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
Look at the picture.
We have the proportion:

Answer: Rayan is 5 ft tall.
Multiply 8 with pi since the equation for circumference is 2pi(r), or d(pi). The answer is 25.13
To solve this problem you must apply the proccedure shown below:
1. The formula for calculate the perimeter of a rectangle is:

Where
is the length and
is the width.
2. The length is
more than the width, therefore:

3. Substitute values into the formula for calculate the perimeter and solve for the width:

3. Then, the length is:

The answer is: The length is
and the width is
