Angles 6 and 7 are vertical angles, not alternate interior.

The same applies to angles 4 and 1, and angles 5 and 8 as well.

Any time you have two lines cross to form an X shape, the angles that are opposite one another are considered vertical angles and are always congruent.

The values you have typed into the boxes are all correct. The other drop-down choices are correct as well. Nice work.

Your mistakes are that you are confusing vertical angles with alternate-interior angles. Angles 6 and 7 for example are vertical angles while angles 3 and 6 are alternate-interior angles.

Verify that the following function is a cumulative distribution function.

SOVA2 [1]

Answer:

Following are the answer to this question:

Step-by-step explanation:

In the given equation there is mistyping so, correct equation and its calculation can be defined as follows:

Given:

$f(x) =\left\begin{array}{cc} 0&x< 1\\0.5& 1 < x$

Calculated value:

$1) \ \ P(x < 3) =1\\\\2) \ \ P(x < 2) = 1-0.5 \\$

$= 0.5$

$3) P(1 < x < 2) = P( x< 2) -p(x< 1)\\\\$

$=0.5-0\\=0.5\\$

$4) \ \ P(x> 2)= 1-P(x$

$=1-0.5\\=0.5\\$

That's why the given equation is true.

∠2 = 60° because all angles of a triangle add up to 180° and 55 + 65 = 120 180 - 120 = 60 lets say the third angle of the triangle is ∠n ∠2 = ∠n so ∠2 = 60°
