P=12 because 2(-4)=-8 and 4(5)=20 so 20+(-8)=12
Lines<span> that are </span>vertical<span> have no </span>slope<span> (it </span>does not exist<span>). </span>Vertical lines<span> have "rise", but no "run".

Answer:
D. Randomly draw and replace a card 100 times. Then, observe how close to 20 times a club is drawn.
Step-by-step explanation:
We are given that,
Martha predicts that 'whenever she draws a card from the deck without looking, she will draw a club one-fifth of the time'.
Now, according to the options, we see that,
If she randomly draw and replace a card 100 times and then observe how close to 20 times a club is drawn.
Her prediction is most likely to be true.
As, 20 out of 100 times is
th of the total time.
Hence, option D is correct.
Answer:
15°
Step-by-step explanation:
AB is parallel to DC and AD is parallel to BC
Therefore, if you put Angle D and Angle C together it must form 180°
If Angle C = 120°, that means Angle D = 60°
Now you subtract 45 from 60 and that gives you 15.
4(square root of 0.0081)
= 4(square root of 81x10^-4
= 4(9x10^-2)
= 36x10^-2
= 0.36
