P-value approach is used to take a decision to reject or accept the null hypothesis as indicated below:
<span>REJECT the hypothesis, if p-value </span><span>FAIL TO REJECT the hypothesis, if p-value > the alpha value.
</span><span>Alpha value represents the level of significance </span>
<span>If alpha value is NOT indicated: alpha = 0.05 can be assumed </span>
<span>REJECT the hypothesis, because p-value (0.036) < the alpha value assumed which is 0.05</span>
The question reminds you of all the tools you need:
It says ...
"Opposite angles are equal."
So the upper right angle is x+40 just like the bottom left,
and the bottom right angle is 3x+20 just like the upper left.
And it says ...
"The sum of all angles is 360°."
You know what each of the four angles is, so you can addum all up,
set the sum equal to 360, find out what number ' x ' is, and then
use that to find the size of every angle.
Answer:
Step-by-step explanation:
(vertical angles)
(Interior angles on the same side of transversal)
X, y - the numbers
The numbers add to 9 and multiply to -70.
The numbers are
-5 and 14.
Step-by-step explanation:
6m+5-3m=7(m-1)
3m+5=7m-1
5+1=7m-3m
6=4m
6/4=m
3/2=m
I think it is correct .
