2sin(pi/3)*cos(pi/3)

here π means 180 degree

2 sin (180/3)*cos(180/3)
2 sin 60° * cos 60° sin 60° =2/3 ,cos60°=1/2

[2*2/3]*[1/2]
4/3*1/2

Find the equation of a line that passes the points (5, -9) and (0, -3)

kobusy [5.1K]

Answer:

y = -6/5x - 3

Step-by-step explanation:

Point Slope Form: (y - y1) = m(x - x1)

Step 1: Find Slope

m = $\frac{y2-y1}{x2-x1}$

m = $\frac{-3 - (-9)}{0 - 5}$

m = $\frac{-3 + 9}{-5}$

m = $\frac{6}{-5}$

m = $\frac{-6}{5}$

Step 2: Plug into Point Slope Form

(y - (-3)) = -6/5(x - 0)

y + 3 - 3 = -6/5x - 3

y = -6/5x - 3

Answer: y = -6/5x - 3

Answer:

It's different because the experiment is more accurate as it progresses.

Step-by-step explanation:

You'll notice that the higher the numbers get in the experiment the closer it gets to your solution. The theoretical probability of flipping a coin is about 50% heads and 50% tails, but it doesn't always seem like that in an experiment. The experimental probability from your experimentation so far would be 62% of heads and 38% of tails.
