Answer:
Mean = 30.3
Median = 30
They scored 30 or more points on 11 games.
Step-by-step explanation:
Mean = all the numbers added together divided by 21
636/21 = 30.3
Median is the middle number (the 11th) = 30
Y = x + 1.75...so we sub in x + 1.75 for y in the other equation
4x - 2y = 4
4x - 2(x + 1.75) = 4....distribute thru the parenthesis
4x - 2x - 3.5 = 4....add 3.5 to both sides
4x - 2x = 4 + 3.5...simplify
2x = 7.5....divide both sides by 2
x = 7.5 / 2
x = 3.75
now we sub in 3.75 for x in either of the original equations to find y.
y = x + 1.75
y = 3.75 + 1.75
y = 5.5
so ur solution is : (3.75,5.5) <==
Answer:
Step-by-step explanation:
N+7 - 7 more songs added

Answer:
I am not 100 percent sure, it's been a long time since I've done this type of math but I think that these are the answers
Step-by-step explanation:
1. x= -3, y=-3
2. x= 5, y= -2
3. x= -3, y = -7
4. x=2, y= 1
5. x=0, y= -4
