Answer:
Step-by-step explanation:
9x + 8 = 7.5x + 17
1.5x = 9
x = 6 hours
Answer:
The population variance and population standard deviation are used when calculating for a population while the sample variance and sample standard deviation are used when calculating for a sample
Step-by-step explanation:
A population is defined as all members of a specified group or simply Population is the whole group. A sample is a part of a population that is used to describe the characteristics, The size of a sample can be less than 1%, or 10%, or 60% of the population.
The population variance and population standard deviation are used when calculating for a population while the sample variance and sample standard deviation are used when calculating for a sample. sample variance(or standard deviation) will be slightly higher than that of the population variance(or population standard deviation) for the same problem if solved. The purpose of this little difference it to get an accurate estimate of the population‘s variance to compensate for the fact it is a sample rather than with the whole population.
E equals 5 because you would subtract 3e on both sides and then you will get 2e equals 10. Lastly you would divide both sides by 2 to get that e equals 5.
Hope I helped!!!
