Since there are 3 "2's" and 8 total options, the probability is 3/8 or C.
A trig identity is <span>asinucosu=<span>a/2</span>sin(2u)</span>So you can write your equation as<span>y=sin(x)cos(x)=<span>1/2</span>sin(2x)</span>Use the crain rule here<span><span>y′</span>=<span>d/<span>dx</span></span><span>1/2</span>sin(2x)=<span>1/2</span>cos(2x)<span>d/<span>dx</span></span>2x=cos(2x)</span>The curve will have horizontal tangents when y' = 0.<span><span>y′</span>=0=cos(2x)</span>On the interval [-pi, pi], solution to that is<span><span>x=±<span>π4</span>,±<span><span>3π</span>4</span></span></span>
wind is predicted for 9 of the days.
rain is predicted for 18 of the days.
cloudiness if predicted for 27 of the days.
sunshine of predicted for 36 of the days.
9 because 9x3=27 or 27/3=9
The answer would be 2 2/3.
