Answer:
Step-by-step explanation:
Males proportion 
Females proportion 
(one tailed test for comparison of proportions)
Test statistic = 
=-1.3641
Here p= combined proportion = 
p value = 0.0869
Since p >0.05, accept null hypothesis.
The evidence does not suggest a higher proportion of females are annoyed by this behavior
Answer:
m∠1=39°, m∠3=51°
Step-by-step explanation:
Angle 3 = 180-(39+90)
180-129=51
Angle 1 = 39 b/c of the corresponding angles.
Answer:
(-4,-2)
x=-4
y=-2
Step-by-step explanation:
-3x-4y=20
3(x-10y=16)=3x-30y=48
The reason I multiplied 3 to the second equation is for when we add the equations together the x will cancel out.
-3x-4y=20
+ <u>3x-30y=48</u>
-34y=68
Divide -34 from both sides.
y=-2
To find x you need to plug in -2 for y into one of the equations.
x-10y=16
x-10(-2)=16
Remember a negative times a negative equals a positive.
x+20=16
Subtract 20 from both sides.
x=-4
Hope this helps!
If not, I am sorry.
