Answer:

See Explanation

Step-by-step explanation:

\overrightarrow{KH} \: bisects \: \angle GKJ (Given)

\therefore \angle GKH \cong \angle HKJ (angle bisector theorem)

\therefore m\angle GKH = m\angle HKJ

\implies m \angle 11 =m \angle 12

m\angle 9 + m\angle 12 = 180\degree.... (1)(Linear pair angles)

&

m\angle 10 + m\angle 11 = 180\degree(Linear pair angles)

\implies m\angle 10 + m\angle 12 = 180\degree.... (2) (\because m \angle 11 = m\angle 12)

From equations (1) & (2)

m\angle 9 + \cancel {m\angle 12} =m\angle 10 +  \cancel {m\angle 12}

\therefore m\angle 9  =m\angle 10

\implies \huge \orange {\angle 9  \cong \angle 10}

Thus proved

which values of x and y are solutions to the open sentence? 4y ≥ 3x 2 a. x = 3, y = 0 b. x = 4, y = 3 c. x = 6, y = 5 d. x = 7,
boyakko [2]
4y ≥ 3x + 2

Plugging in the values in the options, then the required values are when x = 6 and y = 5, then
4(5) ≥ 3(6) + 2
20 ≥ 18 + 2
20 ≥ 20

Find the mean and standard deviation for the set of data.
dem82 [27]

The mean and standard deviation for the set of data will be 16 and 5.87. Then the correct option is A.

<h3>What is a standard deviation?</h3>

It is the measure of the dispersion of statistical data. Dispersion is the extent to which the value is in a variation.

The set of data is given below.

16, 22, 8, 5, 20, 18, 14, 17, 24

The mean of the data set will be

μ = (16 + 22 + 8 + 5 + 20 + 18 + 14 + 17 + 24) / 9

μ = 144 / 9

μ = 16

Then the standard deviation of the data set will be

\rm \sigma = \sqrt{\dfrac{\Sigma (x_i - \mu)^2}{n}} \\\sigma = \sqrt{\dfrac{(16 - 16)^2 +(22 - 16)^2 + (8-16)^2 + ......+(24-16)^2  }{9}} \\\sigma = \sqrt{\dfrac{310}{9}}\\

Simplify the expression further, then we have

σ = √34.44

σ = 5.87

The mean and standard deviation for the set of data will be 16 and 5.87.

Then the correct option is A.

More about the standard deviation link is given below.
