So we want to know the order from the least to greatest for 1/2, 5/6, 2/7 and 4 / 2. Lets turn them into decimal numbers: 1 / 2 = 0.5, 5 / 6 = 0.83334, 2 / 7 = 0.2857 and 4 / 2 = 2. So the order frome the least to greatest is: 2/7 < 1/2 < 5/6 < 4/2. And that is the answer B

Inessa05 [86]

Answer:

14.625

Step-by-step explanation:

As per the situation the solution of mean and standard deviation change, based on all 12 samples is represented below:-

Mean of all 12 samples is shown below:-

$= \dfrac{Sum \ of \ all \ the \ observations}{Total \ number \ of \ observation}$

$= \dfrac{36+14+21+39+11+2+33+45+34+17+1+29}{12}$

So, the Mean = 23.5

and now,

The Standard deviation of all 12 samples is shown below:-

$= \sqrt{\frac{1}{12}} (36-23.5)^2+(14-23.5)^2+(21-23.5)^2+(39-23.5)^2+(11-23.5)^2+(2-23.5)^2+(33-23.5)^2+(45-23.5)^2+(34-23.5)^2+(17-23.5)^2+(1-23.5)^2+(29-23.5)^2}]$

$\sigma$ = 14.625

Therefore, we used the above equation to reach the answer.

Find the exact length of the third side. 5 3

grandymaker [24]

I'm going to assume you want to find the third side of a triangle. We can use the pythagorean theorem to solve; a^2 + b^2 = c^2

a = 5

b = 3

c = ?

Solve.

5^2 + 3^2 = c^2

25 + 9 = c^2

34 = c^2

√34 = √c^2

5.8 ≈ c

Best of Luck!
