Answer:
Ty lol
Step-by-step explanation:
Solution: The standard deviation is used in conjunction with the mean to numerically describe distributions that are bell shaped. The mean measures the center of the distribution, while the standard deviation measures the spread of the distribution.
In normal distribution (bell shaped distribution) , the mean and standard deviation are used to describe its distribution. The mean measures the center of the distribution, while the standard deviation takes care of the spread of the distribution.
The mean of the normal distribution is and the standard deviation is
Answer:
7.5 quarts
Step-by-step explanation:
You first need to find out how much it emits in 1 second. So, 3 quarts divided by 4 seconds is .75, which means the hose emits .75 quarts in one second. Finally, you need to find how much it emitted in 10 seconds. So take how much it emits in one second (.75) and multiply by 10. So therefore, the answer is 7.5 quarts of water in 10 seconds.
They give you a graph so this will be easy. What I do is imagine shading going back to the y-axis from the graph. This is how to get a visual of the range.
Since the shading would go from 4 all the way to negative infinity, the answer is all real numbers less than or equal to 4.
Best of luck!
