Answer:
c+4<d+5
Step-by-step explanation:
Yes because if you rearrange the equation to y=mx+b it would be this
y=5x-2
Becky - x marbles;
Chris - y marbles;
Dan - z marbles
y = 2 x
z = y + 7
x + y + z = 57
--------------------
z = 2 x + 7
x + 2 x + 2 x + 7 = 57
5 x + 7 = 57
5 x = 57 - 7
5 x = 50
x = 50 : 5
x = 10, y = 20, z = 27
Answer: Dan is not correct.
The median is the number in the middle setting the data up from least to greatest.
2, 3, 4, 4, 9, 10, 11, 11, 12, 15.
Median = 9.5
The mean is all the numbers added up and divided by how many there are.
2+ 3 + 4 + 4 + 9 + 10 + 11 + 11 + 12 + 15/10
Mean = 8.1
