The answer is 25 children and 75 adults. Equation 1: A+C= 100 and equation 2: 2c+3a= 275
25(2)=50 75(3)=225.
225+50=275
Also 75+25=100
I think the domain is -1 and the range is 2. You may want to double check though.
Answer:
\mu = 14.5\\
\sigma = 5.071\\
k = 1.084
Step-by-step explanation:
given that a statistician uses Chebyshev's Theorem to estimate that at least 15 % of a population lies between the values 9 and 20.
i.e. his findings with respect to probability are
Recall Chebyshev's inequality that
Comparing with the Ii equation which is appropriate here we find that
Next what we find is
Thus from the given information we find that
In order to help explain how you came to your answer. It also helps when marking or reviewing because it's easier to find any mistakes
You have to make a tape diagram and divide it in to 9 parts because it is 5 out of 9 then you will make a bracket pointing to only 4 parts of the tape diagram then you do 36/9 and it will equal 4 so put 4 in to each part and so 4 x 4 is 16 so the answer is 16 people prefer historical books
