Answer:
Step-by-step explanation:
Since your population are the students in math class, you can use the z-score formula 
in order to comparing the two math test scores. Where 
is the mean for the class, 
is the standars deviation and x is Mary score.
For the first test 
, so ,
.
For the second test 
, so ,
Mary do better in the second test, relative to the rest of the class (because 
, it means the second score is nearer to the mean score of the class than the first one )
Answer: a. 0.9876
Step-by-step explanation:
Given : The distribution of total body protein in healthy adult men is approximately Normal with mean 12.3 kg and standard deviation 0.1 kg.
and 
sample size : n= 25
Let x denotes the total body protein in healthy adult men in the sample.
Then, the probability that their average total body protein is between 12.25 and 12.35 kg will be :-
∴ The correct answer is a. 0.9876
Answer:
D.
Step-by-step explanation:
The function shown on the graph is y = 5x - 6 and it is being comapred to y = 6x - 1. The function shown on the graph has a smaller rate of change because 5x < 6x. The starting point of the function shown on the graph is also lower since - 6 < - 1.
Answer:
100 hours
Step-by-step explanation:
To find the amount of liters in one hour, you divide 10 by 1000, which gives 0.01 liters each hour. From here, the 1 is in the hundredths place, so if you multiply by 100 hours, if will be at 1 liter.
