1) 1/2 * 1/2 = 1/4

2) 43/100 of mine were heads, and (.43)^2 = .1849

3) 1/2 * 1/2 = 1/4

4)57/100 of mine were tails, and (.57)^2 = .3249

5) 1/2 * 1/2 * 2 (multiply by 2 because order doesn't matter) = 1/2

6) .43 *.57 = .2451

7) There is probably a difference becasue there wasn't enough data. The more times you flip the coin, the closer you'd get to 1/2 head 1/2 tails (theoretically), but you can't flip a coin an infinite amount of times, so it (usually) will not give you an exact 1:1 ratio between heads and tails

Sedbober [7]

Answer:

A=\frac{1}{2}a*b*sin(C)

Step-by-step explanation:

First consider the diagram:

Now, we know that

Sin(C)=\frac{AD}{AC} \\ Sin(C) =\frac{h}{b} \\h=bsin(C)

Now, the area of the triangle ABC is given by,

A=\frac{1}{2}*BC*AD\\\\A=\frac{1}{2}*a*h\\\\A=\frac{1}{2}*a*c*sin(C)\\\\A=\frac{1}{2}a*b*sin(C)

15) a) -3 and -4

-3(-4) = 12 (two negative numbers multiplied or divided together = positive answer)

      b) -5 and 6
6(-5) = -30 (one negative number and one positive number multiplied together = negative answer)
-5 + 6 = 1


16) 2.4 kg, 0.7 kg
c) a loss of 15kg should be your answer, because the loss has a larger number proportion than the gained
