Answer:
x=15
Converse: If line x and y are parallel then angles on the same line are supplementary angles.
Step-by-step explanation:
<em><u>Converse:</u></em>
Let's start with the converse, so if line x and y are parallel then angles on the same line are supplementary angles. I'm not sure if that's the converse your teacher wants but my teacher taught me this.
<em><u>Finding x:</u></em>
Now we know that the angles are supplementary angles, that means if w add them together we get 180°. So our equation will be 
. Now we just solve it. We start by combining like terms, then adding the 15 to both sides, and lastly we divide the 13 to both sides and get...
x=15
Answer:
K=2/5
Step-by-step explanation:
So, I’m assuming that by constant of proportionality you mean slope of the line. To do that, you just figure out how y changes with x. The easiest way to do this is rise over run (y over x). If you look at the graph, there is a point that pass through (0,0) and another that passes through (5,2) so if you count how many spaces we moved up then how many spaces we moved right, you will get the slope of the line. Spaces moved up are 2-0=2 and spaced moved right are 5-0=5. Use rise over run which is going to be 2/5. So, K=2/5.

Answer:
0.180144 < p < 0.339856
Step-by-step explanation:
According to the Question,
- Given That, Out of 200 people sampled, 52 had kids, Thus the proportion of the mean is 52/200 = 0.26
⇒
standard error of the sample is square root(0.26 * (1-0.26) / 200) = 0.031
⇒alpha(a) = 1 - 99/100 = 0.01
⇒critical probability(p*) = 1 - a/2 = 0.995
⇒assuming a normal distribution, look for the z-score associated with 0.995 cumulative probability
, z-score = 2.576
⇒margin of error(ME) = 2.576 * 0.031 = 0.079856
-
the confidence interval is 0.26 + or - 0.079856
0.180144 < p < 0.339856
