Crazy boy [7]

Answer:

x = 40

Step-by-step explanation:

Since FG and HI are parallel and BC is a transversal, then

∠ GBE and ∠ GBE are same side interior angles and are supplementary, thus

3x + 20 + x = 180, that is

4x + 20 = 180 ( subtract 20 from both sides )

4x = 160 ( divide both sides by 4 )

x = 40

Find the standard deviation of the data set below. Round to the nearest tenth,<br> 6, 5, 2, 5,8
ASHA 777 [7]

Answer:

The standard deviation = 1.9

Step-by-step explanation:

standard deviation, ρ = sqrt ( \frac{sum(x_{i}  - u)^{2} }{N})

Where u is the mean of the data, x_{i} each given value, and N is the number of data given.

Mean, u = \frac{6+5+2+5+8}{5}

              = 5.2

So that;

(6-5.2)^{2}  = (0.8)^{2} = 0.64

(5-5.2)^{2} = (-0.2)^{2} = 0.04

(2-5.2)^{2}  = (-3.2)^{2} = 10.24

(5-5.2)^{2} = (-0.2)^{2} = 0.04

(8-5.2)^{2} = (2.8)^{2} = 7.84

Sum = 18.8

So that;

\sqrt{\frac{18.8}{5} }  = \sqrt{3.76}

          = 1.9391

          = 1.9

The standard deviation of the given data is 1.9
