What does "well defined" mean to you, in this situation?
What makes up this set is very clear: "1st graders," "Maple Elem. School," "male." No ambiguity here. How does this relate to the concept of "well defined set?"
Answer:
5. x = 5, y = 3
6. x = 0, y = 4
7. x = -1, y = 1
Step-by-step explanation:
5. substitute 3(value of y) into the equation y = x - 2:
=> 3 = x - 2
=> x = 5
6. substitute 0(value of x) into the equation y = x + 4:
=> y = 0 + 4
=> y = 4
7. substitute 1(value of y) into the equation y = 2x + 3:
=> 1 = 2x + 3
=> 2x = -2
=> x = -1
Answer: 0.8490
Step-by-step explanation:
Given : The population of lengths of aluminum-coated steel sheets is normally distributed with a mean of 30.0 inches and a standard deviation of 0.9 inches.
i.e. 
and 
Let x denotes the lengths of aluminum-coated steel sheets.
Required Formula : 
For n= 36 , the probability that the average length of a sheet is between 29.82 and 30.27 inches long will be :-
∴ Required probability = 0.8490
For sewing 3 1/2 shirts, he used = 4 2/3 yards of fabric
Then, for 1 shirt, it would be: 4 2/3 / 3 1/2
Fabric for 1 shirt = 14/3 / 7/2
We can re-write it as: 14/3 * 2/7 = 4/3 yards
In short, Final answer would be 4/3 or 1 1/3 yards
Hope this helps!
