Answer:
# red marbles = 25
# blue marbles = 7
Step-by-step explanation:
r + b = 32
r = 4 + 3b
substitute '4 + 3b' for 'r' in the 1st equation
4 + 3b + b = 32
4 + 4b = 32
4b = 28
b = 7
red = 32 - 7
r = 25

Answer:
mean: 6
median: 6
Step-by-step explanation:
mean = sum of terms divided by number of terms
sum of terms = 11 + 2 + 10 + 3 + 9 + 1 + 6 = 42
number of terms = 7
42/7 = 6
mean = 6
median = the value separating the higher half from the lower half
first, you must organize the numbers from lowest to highest
1, 2, 3, 6, 9, 10, 11
from then, you find the number in the center
that number is 6
median = 6
hope this helps
