Using the z-distribution, it is found that the smallest sample size required to obtain the desired margin of error is of 4330.
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:
In which:
is the sample proportion.
The margin of error is given by:
In this problem:
- The estimate of the proportion is of
.
- The desired margin of error is of M = 0.01.
- 90% confidence level, hence
, z is the value of Z that has a p-value of 
, so 
.
Then, we solve for n to find the minimum sample size.
Rounding up, the smallest sample size required to obtain the desired margin of error is of 4330.

Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object.
The methods of sensing are based on electromagnetic energy released or reflected from Earth's surface at some range above the earth. Remote sensors can be either passive or active depending upon the source of electromagnetic energy.
Earth's surface and atmosphere may involve the use of any of the instruments depending on the type of research to be done.
There are mainly two types of instruments used, passive and active instruments, below are some of the instruments used;
Ozone and Aerosol LiDAR. Radar Wind Profiler, Radiometer, Imaging Radiometer, Spectrometer, Spectroradiometer, Radar (Radio Detection and Ranging), Scatterometer, Lidar (Light Detection and Ranging), Laser Altimeter, SAOZ Instrument.
Answer:
9
Explanation:
First we solve for x. Subtracting 8 from both sides gives us 3x = 15, therefore x would be 5. Then we plug that into the second question, which gives us 5+4, which is 9.
