1+1+1+1+1+5+5+5+5 is one
5+5+5+1+1+1+1+1+1+1+1+1+1 is another
5+5+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1 is three
5+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1 is four.
There are 4 combinations.
The rhombus is shown in the diagram below
The length of one side of the rhombus is 5 units, hence all the other sides are also 5 units each.
Answer:
V = kr²h
Step-by-step explanation:
Given that V varies jointly with r² and h, then the equation relating them is
V = kr²h ← k is the constant of variation
Note that joint variation involves the product of the joint quantities
The sample size must be 543 so the sample proportion is will not differ by 5%
We are given the following in the question:
Margin of error = 5%
Confidence interval:
p ±z√(p'(1 - p')/n)
Margin of error =
p = ±z√(p'(1 - p')/n)
Since no particular proportion is given, we take
p' = 0.5
Z critical at α 0.02 is ± 2.33
Putting values, we get,
p = ±z√(p'(1 - p')/n)
2.33 x √(0.5(1 - 0.5)/n)
√n = 2.33x 0.5/0.05
n = 542.89 = 543
Thus, the sample size must be 543 so the sample proportion is will not differ by 5%
