Answer:
A) Construct a two-sample z -interval for the difference between population proportions.
X equals 100, 0.05×120=6 and 0.06×100=6
Answer:
if a function has degree 9
it will have 9 roots
given 3 are real this means rest (9-3 =6) are not real which means complex
First, make sure that all the variables are in one side. The first equation is gonna be x-y=3
Second, we are going to eliminate the y because it is much easier, but you can also eliminate the x
We have to add both equation because the y in the first equation is negative and in the second equation it’s positive.
We are left with 3x=9
Therefore, x=3
Last, substitute x= 3 in one of the equations
Y=6
P.O.I is (3,6)
You can use and draw you lines
its just rounding to the nearest number
