Answer:
a. 5
Step-by-step explanation:
arrange
1 2 3 5 5 6 6 6 8 9 9 10 10 11 12 13
median=6+8/2=7
range=13-1=12
difference=12-7=5
please mark as brainliest
2+(-3) = -1
2- 3 = -1
-1=-1
The question is why though ?
It is because you keep the negative exponent which is with the biggest number. So this is how its look like +2 -3, so 3 is bigger then 2 so for that reason you keep the negative sign.
I hope that's help:)
Answer:
y(1) = 7
y(2) = 10
y(3) = 13
Step-by-step explanation:
y = 3(1) + 4
y = 3 + 4
y = 7
y = 3(2) + 4
y = 6 + 4
y = 10
y = 3(3) + 4
y = 9 + 4
y = 13
