Answer:
3.33 and 1/3
Step-by-step explanation:
"Dense" here means that there are infinite irrational numbers between two rational numbers. Also, there are infinite rational numbers between two rational numbers. That's the meaning of dense. Actually, that can be apply to all real numbers, there always is gonna be a number between other two.
But, to demonstrate that irrationals are dense, we have to based on an interval with rational limits, because the theorem about dense sets is about rationals, and the dense irrational set is a deduction from it. That's why the best option is 2, because that's an interval with rational limits.
Since you have two numbers that have a (x) at the ends of them, you add those first then add seven which will end up being 9x+7
Step-by-step explanation:
cos θ - sin θ = √2 sin θ
cos θ + sin θ = √2 sin θ + 2sin θ
cos θ + sin θ = √2(sin θ + √2sin θ)
cos θ + sin θ = √2 cos θ. (Proven)
Answer:
183.927844 kg²
Step-by-step explanation:
Calculation for the weight variance:
Given that s =13.5620 kg
The Variance will be the square of the Standard Deviation
S²=13.5620 kg²
S²=183.927844
The units of the variance will be the units of the Standard Deviation Squared which is Kg²
Therefore the variance of their weight will be:
183.927844 kg²
