The box plots represent the ages of pennies in two 50-cent rolls. By looking at the plots, Beth says that the two means are abou
t 5 years apart. Which is true about Beth’s statement? A/ She is correct because the medians are 10 years apart, which means the means are half of that, or 5 years apart. B/ She is correct because the maximum ages of the pennies in each set are 5 years apart. C/ She is not correct because the means are both equal to 12. D/ She may not be correct because means cannot be determined from the box plots.

Answer:
The correct option is D
D) She may not be correct because means cannot be determined from the box plots
Step-by-step explanation:
The question is incomplete because the box plots are not attached in the question. I've attached the box plots of this question at the bottom.
The box plot, also know as box and whisker plot, displays only five type of values, which are:
- Minimum value
- First Quartile
- Median
- Third Quartile
- Maximum value
Mean cannot be determined by just lookin at the box plots. To find the mean, we need to know the values of data and total number of values.
As mean cannot be determined from the box plot, correct option is D

18 + 9x = 49
with the use of an equation you can easily find out if 6 weeks of saving up is enough to get the rabbit.
18 + 9(6) 49
9 x 6 = 54
54 + 18 = 72
you could have enough money in 4 weeks
One Way:
We can change the mixed number to a decimal for comparing.
m = 
m = 1.25 m
1.4 m > 1.25 m
Darren > Luke
Darren's jump was higher by (1.4-1.25) 0.15 m
Or another way change the decimal to a fraction and the mixed to an improper fraction too.
= (Luke)
1.4 =
(Darren)
We need a common denominator to compare
(Luke)
(Darren)
(Luke)
(Darren)
Darren > Luke
By:
- = 
Which is also by 0.15 m
Darren jumps higher and by 0.15 m
We can change the mixed number to a decimal for comparing.
1.4 m > 1.25 m
Darren > Luke
Darren's jump was higher by (1.4-1.25) 0.15 m
