A=1, E = 5, I = 9, O = 15 ans U = 21
1,5,9,15,21
median = 'middle' number = 9
mean = (1+5+9+15+21) / 5 = 10.2
Answer:
20 cups
Step-by-step explanation:
divide 9 by .45 and you get 20
Answer:
W = 12
L = 16
Step-by-step explanation:
Givens
L = L
W = 1/2 L + 4
Perimeter = 56
Formula
2L + 2W = Perimeter
Solution
Sustitute
2L + 2(1/2L + 4) = 56
2L + L + 8 = 56
3L + 8 = 56
3L + 8 - 8 = 56 - 8
3L = 48
3L/3 = 48/3
L = 16
W = 1/2 L + 4
W = 8 + 4
W = 12
Check
2L + 2W = 56
2*16 + 2*12 = 56
32 + 24 = 56
56 = 56 and it checks.
