Arrange the data set in ascending order:
State A: 4, 5, 6, 6, 7, 8, 9, 21, 25
State B: 10, 11, 12, 13, 14, 14, 15, 15, 16
5 number summary:
State A State B
minimum 4 10
Q1 5.5 11.5
median 7 14
Q3 15 15
maximum 25 16
IQR 9.5 3.5
The box plot are not symmetric. The distance of the median from each Q1 and Q3 should be equal for the box plot to be symmetric.

Answer:
B) 20%
Step-by-step explanation:
Exponential equation:
An exponential equation is given by:
In which A(0) is the initial amount and r is the growth rate, as a decimal.
In this question:
Growth rate:
We want to find r, so:
The growth rate is of 0.2 = 2%, and the correct answer is given by option B.
Answer:
The solution is x=1,y=2,z=3
Step-by-step explanation:
The given system of equations is ;\
2x−3y+4z=8...(1)
3x+4y−5z=−4...(2)
4x−5y+6z=12...(3)
Make x the subject in equation (1)
Put equation (4) into equation (2) and (3)
Multiply through by;
Expand;
Simplify;
Equation (4) in (3)
Put equation (6) into equation (5)
z=3
Put z=3 into equation (6)
y=2(3)-4=2
Put y=2 and z=3 into equation 4
The solution is x=1,y=2,z=3
Answer:
$13.50
Step-by-step explanation:
10% of 75 is 7.50 so now we're at 67.5. 2 tubs of popcorn at 6.75 each is equal to 13.5. 67.5 - 13.5 is 54. The rest of the money was spent on tickets. Because it is a family of four we need 4 tickets so divide 54 by 4 which gives you 13.50.
