Answer:
3/4
Step-by-step explanation:
you need to find the change in x and y so you subtract the two x factors and the two y factors if you can simplify it then simplify
Answer:
x = 26 , y = 33
Step-by-step explanation:
3x + 2y = 144 (1)
2x + 5y = 217 (2)
3x + 2y = 144
(divide the equation by 3)
x + (2/3)y = 48
x = 48 - (2/3)y
Plug into (2)
2[48 - (2/3)y] + 5y = 217
96 - (4/3)y + 5y = 217
11y/3 = 217 - 96
11y/3 = 121
y = 121×3/11
y = 33
x = 48 - (2/3)y
x = 48 - (2/3)(33)
x = 48 - 22
x = 26
Mean is the sum of the numbers divided by the number of number
41.42
The median is the middle number, in this case you add the two middle numbers and divide it by 2
61.615
the mode is the number that occurs the most
there is no mode
