Answer:

A and D

Step-by-step explanation:

If these lines are parallel, which I'm assuming they are, we know that any angles across from each other are equal, because they're <u>vertical angles.</u>

So

angle 1 = 41

angle 2 = 139

angle 3 = 139

angle 4 = 41

<u>This means that choices A and D are correct!</u>

What is the population standard deviation of this data set?*
Minchanka [31]

Answer:

C)  2

Step-by-step explanation:

step 1:  Find mean of data set

2+4+4+5+7+8 = 30

30/6 = 5

Mean = 5

step 2: subtract each data value from the mean and square it

5-2 = 3;   3² = 9

5-4 = 1;   1² = 1

5-4 = 1;   1² = 1

5-5 = 0;   0² = 0

5-7 = -2;   (-2²) = 4

5-8 = -3;   (-3²) = 9

Add the squared results:

9+1+1+0+4+9 = 24

Divide 24 by 6 to get the Variance of 4

Take the square root of the Variance to get the Standard Deviation

\sqrt{4} = 2
