Answer:
a
![z-score = 1.57](https://tex.z-dn.net/?f=z-score%20%3D%201.57)
b
![z-score_s = -3.36](https://tex.z-dn.net/?f=z-score_s%20%3D%20-3.36)
Step-by-step explanation:
From the question we are told that
The sample size is n = 103
The sample mean of sag is ![\= x_1 = 353](https://tex.z-dn.net/?f=%5C%3D%20x_1%20%3D%20%20353)
The sample mean of swells is ![\= x_2 = 184](https://tex.z-dn.net/?f=%5C%3D%20x_2%20%3D%20%20184)
The standard deviation of sag is ![s_1 = 30](https://tex.z-dn.net/?f=s_1%20%20%3D%20%2030)
The standard deviation of swells is ![s_2 = 25](https://tex.z-dn.net/?f=s_2%20%20%3D%20%2025)
The number of swell for a randomly selected transformer is k = 100
The number of sag for a randomly selected transformer is c = 400
Generally the z-score for the number of swells is mathematically represented as
![z-score_s = \frac{ k - \= x_2}{s_2}](https://tex.z-dn.net/?f=z-score_s%20%3D%20%5Cfrac%7B%20k%20-%20%5C%3D%20x_2%7D%7Bs_2%7D)
=> ![z-score_s = \frac{ 100- 184}{25}](https://tex.z-dn.net/?f=z-score_s%20%3D%20%5Cfrac%7B%20100-%20184%7D%7B25%7D)
=> ![z-score_s = -3.36](https://tex.z-dn.net/?f=z-score_s%20%3D%20-3.36)
Generally the z-score for the number of sags is mathematically represented as
![z-score = \frac{ c - \= x_1}{s_1}](https://tex.z-dn.net/?f=z-score%20%3D%20%5Cfrac%7B%20c%20-%20%5C%3D%20x_1%7D%7Bs_1%7D)
![z-score = \frac{ 400 - 353}{30}](https://tex.z-dn.net/?f=z-score%20%3D%20%5Cfrac%7B%20400%20-%20353%7D%7B30%7D)
![z-score = 1.57](https://tex.z-dn.net/?f=z-score%20%3D%201.57)
0.4 is exactly 0.01 less than 0.41 .
Answer:
45
Step-by-step explanation:
i hope this helps you :) i would do the middle one but you dont need that one
6^8 = 1679616 that is the answer sir
fractions include 1/3,8/24,12/36 and so on
