A statistical questions is one that can be answered by collecting data and where there will be variability in that data.
the one that most fits that description is the first option "how many sticks of gum can you chew at once?"
System of linear equations
A set of two or more linear equations containing two or more variables.
2x + 3y = −1
x − 3y = 4
Answer:
slope = - 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3x + 2y = 12 ( subtract 3x from both sides )
2y = - 3x + 12 ( divide all terms by 2 )
y = - x + 6 ← in slope- intercept form
with slope m = -
Ed : (0,205)(4,197)
slope(m) = (197 - 205) / (4 - 0) = -8/4 = -2
y = mx + b
slope(m) = -2
(0,205)...x = 0 and y = 205
time to sub
205 = -2(0) + b
205 = b
equation is : y = -2x + 205...so Ed loses 2 lbs per week
Eric :
y = -1.5x + 200...so Eric loses 1.5 lbs per week
when they started, Ed weighed 205 lbs and Eric weighed 200 lbs
* of the two, Eric loses fewer lbs per week. When the two began their respective weight-loss programs, Ed was heavier by 5 lbs.
8.25 because the other half was cut in half so we do the same to both sides.
