Answer:
The table C
Step-by-step explanation:
when you multiply the x number in the table c by 0.3 you get the same answer as the one in the y column. The constant of proportionality  is the value that stays constant in the ratio. Since when you multiply each number in the x column by 0.3 and you always get the number in the y column it shows that the table c is correct.
 
        
             
        
        
        
Answer:
(p ∧ q)’ ≡ p’ ∨ q’
Step-by-step explanation:
First, p and q have just four (4) possibilities, p∧q is true (t) when p and q are both t.
p	∧    q
t	t	t
t	f	f
f	f	t
f	f	f
next step is getting the opposite
(p∧q)'
     <em>f</em>
<em>     t</em>
<em>     t</em>
<em>     t</em>
Then we get p' V q', V is true (t) when the first or the second is true.
p'	V  q'
 f  <em>f</em>  f
 f  <em>t</em>  t
 t  <em>t</em>  f
 t  <em>t</em>  t
Let's compare them, ≡ is true if the first is equal to the second one.
(p∧q)'   ≡     (p' V q')
     <em>f              f </em>
<em>     t              t</em>
<em>     t              t</em>
<em>     t              t</em>
Both are true, so
(p ∧ q)’ ≡ p’ ∨ q’ 
 
        
             
        
        
        
Answer:
65 degrees
Step-by-step explanation:
Break the parallelogram up into two triangles. Angle E is 70 degrees and 45 degrees because of the property of equal opposite angles. So E 45 degrees Y 70 degrees and if you add the two up you get 115 degrees. There are 180 degrees in a triangle, so 180-115=65.
