Answers:
x = 6 and P = 128
=================================================================
Explanation:
The tangents CT and CU are equal to each other. The rule is that tangent segments that meet at a common point are the same length.
Let's solve for x
CT = CU
3x = 18
x = 18/3
x = 6
Because CT = 18, this makes BC = BT+TC = 12+18 = 30
---------------------------
For similar reasoning as mentioned earlier, we can say tangents BT and BV are the same length. This means BV = 12.
Segment CD = 52 and CU = 18, which makes UD = CD-CU = 52-18 = 34
From there, we can say segment DV = 34 also. This leads to BD = BV+VD = 12+34 = 46
Triangle BCD has the three sides
The perimeter is
P = sum of the three sides
P = (side1)+(side2)+(side3)
P = BC + CD + BD
P = 30+52+46
P = 82+46
P = 128
Answer:
Step-by-step explanation:
Given that a research institute poll asked respondents if they felt vulnerable to identity theft. In the poll, n=1096 and x=542 who said yes.
i.e. sample size = 
who said yes =
Sample proportion = 
Std error of proportion = 
Margin of error 95% 
Hence confidence interval for proportions
=
a) Point estimate 
B) Margin of error = 
C) Conf interval = 
D) We are 95% confident that for large random samples representing the population, the proportion of yes will lie between these two values.

Answer:
Step-by-step explanation:
Angles 3 and 6 are consecutive interior angles
<u>As per definition, consecutive internal angles add to 180°</u>
- m∠3 = 67° ⇒
- m∠6 = 180° - 67° = 113°
