Answer: 0.2551
Step-by-step explanation:
Given : The temperature reading from a thermocouple placed in a constant-temperature medium is normally distributed with mean μ, the actual temperature of the medium, and standard deviation σ.
Significance level : 
The critical z-value for 95% confidence : 
(1)
Since , 
(where x be any random variable that represents the temperature reading from a thermocouple.)
Then, from (1)
(2)
Also, all readings are within 0.5° of μ,
i.e. 
i.e. 
[From (2)]
i.e. 
i.e. 
The required standard deviation : 
Answer:
edge 2020
Step-by-step explanation:
The data appears slightly skewed, so the median is probably the most appropriate measure.
My friend has a good chance of making between $16,000 and $23,000 because that is the range for the middle 50% of employees.
Answer:
Step-by-step explanation:
<u>Theorem 1:</u> The height of right triangle drawn from the right angle to the hypotenuse divides the hypotenuse into two segments. The length of the altitude is the geometric mean of these two segments. Hence,
<u>Theorem 2:</u> In a right triangle, the altitude drawn from the right angle to the hypotenuse divides the hypotenuse into two segments. The length of each leg of the right triangle is the geometric mean of the lengths of the hypotenuse and the segment of the hypotenuse that is adjacent to the leg.
Thus,
Just a matter of subbing answer choices into ur inequality to see which is true.
answer is : (3,-2)
There are 8 equal parts. Each part is 1/8 of the whole 8/8
