Answer: 0.3061.
Step-by-step explanation:
Given : The temperature reading from a thermocouple placed in a constant-temperature medium is normally distributed with mean 
, the actual temperature of the medium, and standard deviation 
.
Let X be the random variable that represents the reading of the thermometer.
Confidence level : 
We know that the z-value for 95% confidence interval is 1.96.
Then, we have
But all readings are within 0.6° of .
So, 
Hence, the required standard deviation will be
Hello,
(2x^6-9x^5+4x^2-5)|x^3-5
-(2x^6-10x^3 ) | 2x^3 -9x^2 +10
-------------------
-9x^5 +10x^3 +4x^2-5
-(-9x^5+45x^2)
---------------------------
10x^3-41x^2-5
-(10x^3-50)

Hello!
Answer: 80 kilograms
Explanation: The sumo wrestler wanted to gain weight so an amount is being added to his current weight. As the question tells us, t is the months. Therefore 5.4 is the amount gained per month, resulting in 80 being the wrestler's starting weight. Whenever you are working on a problem like this just go through and figure out based on what you are told, what certain parts are, then go from there.
I hope that helps you!
Good luck!
