Order the number:
42,42,45,45,48,50,50,55,60,65,80
Mean:50
Quartile 1:45
Quartile 3:60
60-45=15. As a result, the interquartile range is 15. Hope it help!
Step-by-step explanation:
Look for keywords
when you see "per" that means theres a rate (something happens every unit of time)
To write a rate you divide whatever happens by whatever unit of time youre useing
In this example our rate is 15$ <em>per</em> hour which can be written as:
15$/1 hour (but we usually dont write it if theres a 1)
You can think of this as a regular fraction
![\frac{15}{1 \: hour} \times 25 \: hour](https://tex.z-dn.net/?f=%20%5Cfrac%7B15%7D%7B1%20%5C%3A%20hour%7D%20%20%5Ctimes%2025%20%5C%3A%20hour)
Here the hour will cancel and youre left with $

Answer: a) 0.159, b) 0.366, c) 0.038.
Step-by-step explanation:
Since we have given that
Number of singles = 105
number of doubles = 2
Number of triples = 8
Number of home runs = 25
Number of strikeouts = 147
Number of walks = 95
Total number of times = 662
So, probability of him hitting a single when he comes to bat would be
![\dfrac{Single}{total}=\dfrac{105}{662}=0.159](https://tex.z-dn.net/?f=%5Cdfrac%7BSingle%7D%7Btotal%7D%3D%5Cdfrac%7B105%7D%7B662%7D%3D0.159)
Probability of getting he strikes out or walks when he comes to bat would be
![\dfrac{Strikes\ out+walk}{Total}=\dfrac{147+95}{662}=\dfrac{242}{662}=0.366](https://tex.z-dn.net/?f=%5Cdfrac%7BStrikes%5C%20out%2Bwalk%7D%7BTotal%7D%3D%5Cdfrac%7B147%2B95%7D%7B662%7D%3D%5Cdfrac%7B242%7D%7B662%7D%3D0.366)
Probability that it is a home run is given by
![\dfrac{Home\ run}{Total}=\dfrac{25}{662}=0.038](https://tex.z-dn.net/?f=%5Cdfrac%7BHome%5C%20run%7D%7BTotal%7D%3D%5Cdfrac%7B25%7D%7B662%7D%3D0.038)
Hence, a) 0.159, b) 0.366, c) 0.038.
