10 because 8 squares plus 6 squared equals 100 and the root of 100 is ten
Simplify. Distribute 2 to all terms within the parenthesis
2(m -3) = 2m - 6
Simplify. Combine like terms
2m - 6 + 7 < 21
2m + 1 < 21
Isolate the m. Subtract 1 from both sides
2m + 1 (-1) < 21 (-1)
2m < 20
Isolate the m. Divide 2 from both sides
2m/2 < 20/2
m < 20/2
m < 10
m < 10 is your answer
hope this helps
Solution:
we are given that
Don walked 3 3/5 miles on Friday
It can be re-written as
miles
3 5/8 miles on sunday.
It can be re-written as
miles
an d He walk 3.7 miles on satarday.
The distances from least to greatest is 3.6, 3.625, 3.7
or
The distances from least to greatest is 
miles, 
miles, 3.7 miles.
Answer:
When sampling from a population, the sample mean will: be closer to the population mean as the sample size increases.
Step-by-step explanation:
The sample mean is not always equal to the population mean but if we increase the number of samples then the mean of the sample would become more and more closer to the population mean.
Usually the population size is very huge that is why we select a random sample from the population, care must be taken to ensure randomized sampling otherwise results would not be accurate. After that we have to make sure that the number of samples are enough for the given population size. The number of samples depends upon the shape of the population. If the population is normal than according to central limit theorem, a less number of samples would be enough to ensure normal distribution of sampling mean, otherwise a greater sample size will be required.
Answer is Rachel worked 3 2/3 hours
Step by step
Dominic worked 2 3/4 hours
Rachel worked (1 1/3) times (2 3/4)
1 1/3 x 2 3/4. Change into an improper fraction
4/3 x 11/4. multiply across
44/12
Simplify
= 3 2/3
