The mean would be 4.5. This is because you add up all the numbers which equals 22.5. Then divide by 5 since there is 5 numbers in the set. So the answer comes out to be 4.5.
Answer:
5
Step-by-step explanation:
The geometric mean of 2 numbers a and b is
Hence
The geometric mean of 5 and 10 is
= 
= 
= 
× = 5
Answer: Use employee identification numbers to randomly select 200 employees
Step-by-step explanation:
Random sampling refers to a sampling technique whereby each sample has an equal chance of being selected. It is an unbiased representation of the entire population and this is vital in drawing conclusion.
From the options given, the best way to randomly choose these 200 employees will be to use employee identification numbers to randomly select 200 employees.
Answer:
Step-by-step explanation:
Sinθ = opp/hyp
Sinθ = 12/13
θ = ArcSin (12/13)
θ =67.38
Let x = adj
Tan (67.38) = 15/x
2.4= 15/x
x2.4= 15
x=6.25
Therefore the missing value is 6.25
This is a relatively easy half life calculation.
After one half-life period, half of the isotope remains.
After two half-life periods, one quarter of the isotope remains.
That being the case, we see this will take 2 half-life periods or 6 days.
