Answer:
Step-by-step explanation: Dot plot for movies seen by a students in a month
To Find : measures of spread
Solution:
Movies frequency cumulative frequency
0 1 1
1 0 1
2 0 1
3 0 1
4 3 4
5 8 12
6 3 15
7 1 16
8 5 21
9 2 23
10 3 26
Range = 10 - 0 = 10
Q2 = (6 + 6)/2 = 6 (13th + 14t)/2
Q1 = 5 7th
Q3 = 8 20th
IQR = Q3 - Q1
= 8 - 5
= 3
M = 6w - 31
m + w < 11
6w - 31 + w < 11
7w - 31 < 11
7w < 11 + 31
7w < 42
w < 42/7
w < 6
oldest age warren can be is 5...but I do not see how that is possibly because if warren is 5, then marty is : 6(5) - 31= 30 - 31 = -1
unless u make warrens age 5 1/2....making warrens age 2...wait, that wont work because u need a whole number
Option C would be the correct answer :)
