Answer:
I believe the answer is: These scores are more likely to have an effect because of the large sample size
In asking about satisfaction, the data could only come from the life experiences or personal principle of the individuals in the samples. Because of this, the scores would have relatively same effect regardless of the amount of sample size that the researchers use.
Mean number of points scored=(3+14+10+0)/4
=6.75
Answer:
1 Adult ticket=$21.50 ; 1 Children ticket=$15.50
Step-by-step explanation:
3A+4C=126.50
2A+5C=120.50
We find the price of adult tickets 1st.
15A+20C=632.5
8A+20C=482
7A=632.5-482=150.5
1A=21.50
Now we find Children ticket
6A+8C=253
6A+15C=361.50
7C=108.50
1C=15.50
Part A:
Let the length of one of the sides of the rectangle be L, then the length of the other side is obtained as follow.
Let the length of the other side be x, then

Thus, if the length of one of the side is x, the length of the other side is 8 - L.
Hence, the area of the rectangle in terms of L is given by

Part B:
To find the domain of A
Recall that the domain of a function is the set of values which can be assumed by the independent variable. In this case, the domain is the set of values that L can take.
Notice that the length of a side of a rectangle cannot be negative or 0, thus L cannot be 8 as 8 - 8 = 0 or any number greater than 8.
Hence the domain of the area are the set of values between 0 and 8 not inclusive.
Therefore,
Answer:no
Step-by-step explanation:
5(3(10)+8)
5(30+8)
5(38)=190
8(10)+8
80+8
88
88≠190 so no
