If θ is an angle in standard position that terminates in Quadrant IV such that cosθ = 3/5, then cosθ/2 = _____. -

Sveta_85 [38]

Answer:

$cos \frac{\theta}{2}= 0.894$ .

Step-by-step explanation:

Given:

$cos\ \theta= \frac35$

We need to find $cos \ \frac{\theta}{2}$

Solution:

$cos\ \theta= \frac35$

First we will find the value of $\theta$ .

Now taking $cos^{-1}$ on both side we get;

$\theta= cos^{-1} \ \frac{3}{5}\\\\\theta = 53.13$

Now we will find the $\frac{\theta}{2}$ .

$\frac{\theta}{2}$ = $\frac{53.13}{2} = 26.565$

Now we will find $cos \ \frac{\theta}{2}$ we get;

$cos \frac{\theta}{2}=cos\ 26.565 = 0.894$

Hence $cos \frac{\theta}{2}= 0.894$ .

How do i find mean absoulute deviation

rosijanka [135]

Step-by-step explanation:

Below are an example using the data values

{ 11 , 10 , 17 , 18 }

Step 1: What is MAD?

MAD is the average distance between each data value. <MAD> is used to see variation of the data. The larger the MAD, the further apart the numbers are.(and vice versa)

Step 2: Find the mean

11 + 10 + 17 + 18 = 56

56/4 = 14

Step 3: Formula to find the Absolute Deviations or distance of the data value to the mean

Find the absolute value of the difference between each data value and the mean: | data value – mean | or I mean - data value I

Step 4: Find the Absolute Deviations

14 - 11 = 3

14 - 10 = 4

17 - 14 = 3

18 - 14 = 4

Step 5: FInd the mean of the Absolute Deviations or MAD

3 + 4 + 3 + 4= 14

14/4 = 3.5
