6/11=x/33 is not a proportion because they aren't equal to each other.
The decimal 0.5<span> represents the </span>fraction<span> 5/10. The decimal 0.25 represents the </span>fraction<span> 25/100. Decimal </span>fractions<span> always have a denominator based on a power of 10. We know that 5/10 is equivalent to 1/2 since 1/2 times 5/5 is 5/10.</span>

Step-by-step explanation:
Answer:
Mean=16.5
Median=9.5
Step-by-step explanation:
I believe the problem ask for s which is the standard
deviation. We must recall that the formula for z statistic is stated as:
z = (x – x over bar) / s
Where,
z = z statistic = 2.5
x = sample value or sample score = 102
x over bar = the sample mean or sample average = 100
s = standard deviation = unknown
Rewriting the equation in terms of s:
s = (x – x over bar) / z
Substituting the given values into the equation:
s = (102 – 100) / 2.5
s = 0.8
Therefore the standard deviation s is 0.8
