In a symmetric distribution, better known as the Gaussian or normal distribution, two thirds of the observations or 66.67% of the observation belongs to the area between the -3∅ to +3∅ where ∅ is the standard deviation of the group. it is assumed here that the mean is 1 and the area under the curve is also 1.
Answer:
4:7
16:28
020:35
020 is meant to look hard, but it just equals 20
Answer:
5√5
Step-by-step explanation:
To find the distance you can use the distance formula.
√(13 - 8)^2 + (4 + 6)^2
√25 + 100
√125
5√5
66 and 2/3 in a fraction would be 200/3 n lowest terms
You have to multiply 200 by 3 and add 2 to get 200
66 and 2/3 in a decimal would be 66.67
Divide 2/3 to get .67 and add 66.
