Mean = 60.5
Median = 57.5
Mode = no mode
Range = 55
The answer would be 240 because 12 times 8 equals 96 and 18 times 8 equals 144 but you have to add it so the answer is 240
Let X be chickens
Let Y be pigs,
then x+y=13
the animals have 2x+4y legs,
so 2x+4y=40
The system of the equations
[X+y=13
[2x+4y=40
Divide the second equation by 2
[x+y=13
[x+2y=20
subtract the first equation from the second one
y=20-13
y-7 pigs
substitute y=7 into the first equation
x+7=13
x=13-7
x=6 chickens
Answer:
12.5
Step-by-step explanation:
4.5 - 3 = 1.5, so 11 + 1.5 = 12.5
