Answer:

Step-by-step explanation:

You know that angle Y is a right angle because XY is the radius and YZ is a tangent to the circle. So, you can use the pythagorean theorem to find the third side:

XY^2+4^2=5^2

XY^2+16=25

XY^2=9

XY=3

Answer:

3.14

Step-by-step explanation:

First find the circumference of the circle:

$2\pi r$ = Circumference.

$2 * \pi * 6$ = $12\pi$

Find the ratio of the angle in relation to the entire circle:

$30^o$ is what we have. So:

$\frac{30^o}{360^o} = \frac{1}{12}$

Use the ratio and multiply the circumference to find the length:

$12\pi * \frac{1}{12}$ = $\pi$

Round answer to the hundredth:

$\pi = 3.14$

Find the MAD for this set of data.

Nostrana [21]

Answer:

Hence MAD=0.8

Step-by-step explanation:

MAD is also known as Mean Absolute Deviation.

We find MAD by the following steps:

Firstly we find the mean of the data
Then we subtract each entry from the mean to obtain the deviation
Then find the absolute value of the deviation which is also known as absolute deviation.
Finally we find the mean of the absolute deviation.

Now we are given a table of the absolute deviation we just need to calculate the mean of the absolute deviation.

The absolute deviation is given as:

1 3 1 0 0 1 0 0 1 1

The mean of this is calculated as:

$\dfrac{1+3+1+0+0+1+0+0+1+1}{10}=\dfrac{8}{10}=0.8$

Hence, MAD=0.8
