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:
<em>Perimeter of ABC = AB + BC+AC. Replace letters with equations.</em>
<em>3x^2-7x+2</em><em> = </em><u><em>2x^2-10x+6 + x^2-x-4 + AC</em></u><em> = </em><em>3x^2-11x+2 + AC</em><em>.</em>
<em>AC = 4x;</em>
Cot(theta) = 1/tan(theta) = cos(theta)/sin(theta) =
cos(theta)/sqrt(1-cos^2(theta))
cot(theta) = cos(theta)/sqrt(1-cos^2(theta))
cot^2(theta)(1-cos^2(theta))=cos^2(theta)
(cot^2(theta)+1)cos^2(theta)=cot^2theta
cot(theta)/sqrt(cot^2(theta)+1)
