20,000 - 12,000 = 8,000

8,000 divided by 12,000 = 0.6666666666667or something

0.66666666666667 x 100 = 66.66666666667

so it should be the second option.

What is the minimum number of clients the travel agent should survey? Note that z=1.96 for a 95% confidence interval.
slega [8]

Answer:

121

Step-by-step explanation:

Given data as per the question

Standard deviation = \sigma = 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

n = (\frac{z\times \sigma}{E})^2

=  (\frac{1.96\times 840}{150})^2

= 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

A mother wants to invest $5,000.00 for her son's future education. She invests a portion of the money in a bank certificate of d
Lostsunrise [7]
Let us say, the CD amount she invested is "c"
and  the amount she invested in the savings bond is "s"

she invested a total of 5,000
so, whatever "c" is and "s" is, c + s = 5,000

now, the CD account earned 4% in interest
4% in decimal form is 4/100 or 0.04

she also earns 7% from the saving bonds,
7/100 is 0.07

the interest earned after one year are 300
that is, the 4% per year and the 7% per year add up to 300 bucks
so, one can say that

0.04c + 0.07s = 300

\begin{cases}
c+s=5,000\to s=\boxed{5,000-c}
\\ \quad \\
0.04c+0.07s=300\to 0.04c+0.07(\boxed{5,000-c})=300
\end{cases}
\\ \quad \\
\textit{solve for "c", or CD amount}
