Step-by-step explanation:
Answer:
x = 10 meter
y= 20 meter
shadw of a man = 10 meters
Answer:
You are asked for an angle. You need to use the inverse sine.
The answer is about 30 degrees. See below.
Step-by-step explanation:
Sin(y) = opposite / hypotenuse
opposite = 9cm
hypotenuse = 17 cm
Sin(y) = 9/17
y = sin-1(9/17)
y = sin-1(31.97) degrees.
To the nearest 1/10 of a degree, it would be
y = 32.0 degrees.
The earth travels 1,050 miles in an hour.
There are 24 hours in a day.
So multiply 1,050 by 24.
And you get 25,200.
The earth travels 25,200 miles in a day.
Using sampling concepts, one sample of 5 high schools in the city of Chicago is given by:
Brooks, Hyde Park, Young Womens, Marshall, Noble - UIC.
<h3>What is the missing information?</h3>
The problem is incomplete, but researching it on a search engine, it gives us a list of 15 high schools in Chicago, and asks us to take a sample of 5.
<h3>What is population and sample?</h3>
- Population: Collection or set of individuals or objects or events whose properties will be studied.
- Sample: The sample is a subset of the population, and a well chosen sample, that is, a representative sample will contain most of the information about the population parameter. A representative sample means that all groups of the population are inserted into the sample.
Hence, from the concepts of sample and populations, the sample of 5 means that we have to select 5 schools from the 15 listed, hence one possible option is given by:
Brooks, Hyde Park, Young Womens, Marshall, Noble - UIC.
