plzzz
mark it as a brilliant answer
Answer:
a) y = 6x - 3
b) 1/3y = 2x -1
The first thing you need to do is isolate (y) in the second equation
3 x (1/3y) = 3 x (2x - 1)
y =6x - 3
After isolating (y) in equation b they end up being the same.
Graphing:
In order to graph this, you have to make the first point at (0, -3) since this is the Y-intercept of the equation.
In order to graph the other points, you must move 6 units up and 1 unit to the right. Or vise versa If you need a visual I'll gladly link one.
Answer:
I can only do mean and median
First, you have to write it in decreasing order
1, 4, 5, 6,7,8,9,9,9,11
Now, we seperate them
1, 4, 5, 6,7,8,9,9,9,11
the two middle numbers are 7 and 8 so the median is 7.5
upper quartile: 8,9,9,9,11
lower quartile: 1, 4, 5, 6, 7
To find the mean, we have to add all the numbers and divide it by the amount of numbers. There are 10 numbers and added togetehr they are 69 so divide 69 by 10 so 6.9 for the mean and 7.5 for median
