Answer:
Paired t-test
Step-by-step explanation:
paired t–test is used when there is one measurement variable and two nominal variables. The most common design is that one nominal variable represents individual organisms, while the other is "before" and "after" some treatment.
Answer:
-4, 3
Step-by-step explanation:
you got's it :)
3x+y=17
=> 3x=17-y
Again, x+3y=-1
=> 3y= -1-x
now, 3x+3y= (17-y)+(-1-x)
= 17-y-1-x
= 16-x-y
Step-by-step explanation:
12 . The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis. Thinking about intercepts helps us graph linear equations..
Squrae has 4 sides of equal legnth
perimiter=legnth of all sides added together or distance around (peri=around, meter=measure)
so 4 sides
each side is equal
1 sides=5.6
perimiter=5.6 times 4=22.4 cm is answer
