Answer:
1.5
Step-by-step explanation:
To find the mean, we must add all of our terms, and then divide by the number of terms.

Solve:

Since we have seven terms, we must divide our total (
), by seven.
÷ 
Solve:
÷ 
Therefore, the mean is 
Answer:
x = 60
Step-by-step explanation:
Total degrees of all interior angles (the three angles inside the triangle) is always 180°
So u use 180/3 = 60 which is x
A. T(15) is the temperature of water after 15 seconds
C. T(60) is the temperature of the water after 1 minute
Answer: 0.4302
Step-by-step explanation:
Given : Mean : 
Standard deviation : 
Sample size : 
Also, these distances are normally distributed.
Then , the formula to calculate the z-score is given by :-

For x=32.5

For x=40.5

The p-value = 

Hence, the required probability :-0.4302
The Z-37 lies between the 2 and 3 standard deviations of the mean. Then the correct option is C.
<h3>What is normal a distribution?</h3>
It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.
The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.
A supervisor finds the mean number of miles that the employees in a department live from work.
μ = 29 and σ = 3.6
Z-37
Then we have

Then Z-37 lies between the 2 and 3 standard deviations of the mean. Then the correct option is C.
