The mean is: 81.6 The median is: 81 Its mode is: 81 and 83 because its bi-modal
(4/9)³ = (4/9) × (4/9) × (4/9)(4/9) × (4/9) = 16/81(16/81) × (4/9) = 64/729
(.81)(.81)(.81)(.81)(.81)(.81) = .2824 p = 1 - .2824 = .7176 answer = .7176
There are an infinite list of different sets of 5 that do that.If their mean is 80, then the only thing you know about them is that they add up to 400.Here's one set:78, 79, 80, 81, 82Here's another one:79, 81, -600, 400, 440.The mean doesn't tell us anything about what the individual numbers must be.
For the set (87 81 75 75 75 70 62 62 62 62 62 56 56): The mean is 68.076923 repeating The median is 62 The mode is 62
The geometric mean of 9 and 81 is 27.0
Just use the definition of geometric mean. Multiply the two numbers, then take the square root of the result. (To take the geometric mean of three numbers, multiply all of them, then take the cubic root, etc.)
Their geometric mean is:sqrt(42*(1/9)2)=sqrt(16*(1/81))=sqrt(16/81)=4/9-------------------The geometric mean of a set of n terms is equal to the nth root of the product of those n terms. The geometric mean of 4 and 1/9 is sqrt(4*(1/9)) = sqrt(4/9) = 2/3.
geo. mean=√(49x81)=7x9=63
mean = (4 + 81)/2 = 85/2 = 42.5
144:81 can be reduced to a 16:9 ratio.
No. 81 is not evenly divisible by 16.
This is not a geometric series since -18/54 is not the same as -36/12
√(16/81) = (√16)/(√81) = 4/9 → The two roots are 4/9 and -4/9
Greatest Common Divisor (GCF) for 81 16 is 1.
