What is the area:
pychu [463]
Triangle formula: 1/2base(height)
So 1/2(6) * 9
3*9 = 27ft^2
Parallelogram formula: length(width) or base(height)
So 18(13)= 234m^2
Triangle formula above so 1/2(20)*9
So 10*9 = 90in^2

Jorge wants to draw a conclusion about the possible expected values of rolling a 2 on a standard die for different numbers of ro
spin [16.1K]
<span>may result in an expected value that is even, odd, or a decimal.</span> The expected value is equal to the product of the theoretical probability of rolling a 2 on 1 die roll, or <span>1/6</span>, and the number of die rolls. A total of 300 rolls gives an expected value of 50, which is even. A total of 200 rolls gives an expected value of 33.3, which is a repeating decimal. A total of 30 rolls gives an expected value of 5, which is odd.
