Answer:
22.5miles
Step-by-step explanation:
For Map 1;
1 inches = 30miles
For Map 2:
2 inches = 15miles
1 inches = x
2x = 1 *15
x = 15/2
x = 7.5miles
This means that 1 inch represents 7.5miles on Map 2'
The distance between the two cities in miles = 30miles - 7.5miles
The distance between the two cities (in miles) = 22.5miles
To make a box and whisker plot you must first order the data:
11, 13, 16, 18, 21, 23, 24, 29
Then find the median:
19.5
Then split the data into two sections by the median:
11, 13, 16, 18 and 21, 23, 24, 29
Now find the medians of those sets
14.5 and 23.5
With this information we can conclude Option C is the correct plot
Hope this helps!

Step-by-step explanation:
Let the youngest sister be n years
Lana will be 2n years, as her youngest sister is half her age
The age of the twins separately will be 2n-2 as they are 2 years younger than Lana
So, the equation looks like this:
n + 2n + 2(2n-2) = 45
Now solve for n:
3n + 4n - 4 = 45
7n - 4 = 45
7n = 49
n = 7
So the youngest sister is 7, Lana is 14 and the twins are 12. 14 + 12 + 12 + 7 =45
