i am not sure about #1 though good luck
We are given a line of thought trying to prove different entities proven to be congruent by different argument or proof. Evenutally, the two are associated using a property called transitivity. This property is used to associate A and C when A is equal to B and B is equal to C
Answer: The 95% confidence interval for the mean of x is (94.08, 101.92) .
Step-by-step explanation:
We are given that ,
A random variable x has a Normal distribution with an unknown mean and a standard deviation of 12.
i.e. 
Also, it is given that , Sample mean
having sample size : n= 36
For 95% confidence ,
Significance level : 
By using the z-value table , the two-tailed critical value for 95% Confidence interval :

We know that the confidence interval for unknown population mean
is given by :-

, where
= Sample mean
= Population standard deviation
= Critical z-value.
Substitute all the given values, then the required confidence interval will be :




Therefore, the 95% confidence interval for the mean of x is (94.08, 101.92) .
Answer:
73 feet.
Step-by-step explanation:
Given:
A rope from the top of a pole is anchored to the ground which is 55 ft away from the base of the pole.
The pole is 48 ft tall.
Question asked:
What is the length of the rope?
Solution:
Here we found that a right angle triangle is formed in which base and height is given <u>as shown in the figure, </u>we have to find the longest side of the triangle,
Base = 55 feet
Height = 48 feet
Length of the rope = ?
By Pythagoras theorem:
Square of longest side = Square of base + Square of height



Taking root both side
![\sqrt[2]{(Longest\ side)^{2} } =\sqrt[2]{5329}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B%28Longest%5C%20side%29%5E%7B2%7D%20%7D%20%3D%5Csqrt%5B2%5D%7B5329%7D)

Thus, length of the rope is 73 feet.
