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 rectangular prism of volume 3200 mm has a rectangular base of 10 mm and width 8 mm. Find the height h of the prism
Orlov [11]

Answer:

40 mm

Step-by-step explanation:

The rectangular prism of a rectangular box. The volume is given by the formula:

<u>Volume of Rectangular Prism</u> = length * width * height

Given Volume = 3200

Length = 10

Width = 8

We need to find height. So we plug in the given information and find the height, in mm. Shown below:

Volume = Length * Width * Height

3200 = 10 * 8 * Height

3200 = 80 * Height

Height = 3200/80

Height = 40 mm

The height (h) = 40 mm

Which expression is equivalent to 4p^-4 10q -3? Assume ​
lozanna [386]

Step-by-step explanation:

Derive an expression for the equivalent width in a saturated line. Assume a Voigt profile, with the difference in optical depth between the center of the line and the wings being ~104. The wings of the line can be ignored. Define a frequency x1 = (v1 − v0)/ΔvD, where the optical depth τv = 1. Inside of x1 the line is fully saturated, and outside x1 the line is optically thin. Show that the equivalent width is



Note that the equivalent width is practically insensitive to the number density of absorbing material.

Please help! Will award brainliest. Simplify the expression -5+i/2i. Please show your work.
lorasvet [3.4K]

(-5+i)/2i

multiply by i/i

(-5+i) *i = -5i +i^2 = -5i -1

2i*i = 2i^2 = 2(-1) = -2

(-1-5i)/-2

1/2 +5/2 *i
