It doesn't sa how many balloons are purple but ill still help u

This is an dependent variable and let x stand for the number of purple balloons

the chance that u hit a purple with teh first dart is x/15

The chance that u hit a purple with the second dart is x-1/14

the answer is x/15 times x-1/14

To play a game, you spin a spinner like the one shown. You win if the arrow lands in one of the areas marked "WIN". Lee played t
Mrac [35]
The data collected from the actual game experiment is:

Win: 8 times
Lose: 40 times
Total trials: 48 times

Therefore, the probability that you will win when you play this game is:

WIN = 8/48
        = 1/6 or 0.1667 = 16.67% chance of winning

LOSE = 40/48
           = 5/6 or 0.8333 = 83.33% chance of losing.

Prove: cot(x) sec^4(x) = cot(x) +2tan(x) + tan^3(x)
masha68 [24]
\bf cot(\theta)=\cfrac{cos(\theta)}{sin(\theta)}&#10;\qquad\qquad &#10;sec(\theta)=\cfrac{1}{cos(\theta)}\quad\qquad  1+tan^2(\theta)=sec^2(\theta)\\\\\\&#10;tan(\theta)=\cfrac{sin(\theta)}{cos(\theta)}&#10;\qquad \qquad cot(\theta)=\cfrac{cos(\theta)}{sin(\theta)}&#10;\\\\&#10;-------------------------------\\\\&#10;cot(x)sec^4(x)=cot(x)+2tan(x)+tan^3(x)\\\\&#10;-------------------------------\\\\

\bf \textit{so, let's do the left-hand-side}\\\\&#10;cot(x)sec^2(x)sec^2(x)\implies cot(x)[1+tan^2(x)][1+tan^2(x)]&#10;\\\\\\&#10;cot(x)[1^2+2tan^2(x)+tan^4(x)]&#10;\\\\\\&#10;cot(x)+2tan^2(x)cot(x)+tan^4(x)cot(x)&#10;\\\\\\&#10;cot(x)+2\cdot \cfrac{sin^2(x)}{cos^2(x)}\cdot \cfrac{cos(x)}{sin(x)}+\cfrac{sin^4(x)}{cos^4(x)}\cdot \cfrac{cos(x)}{sin(x)}&#10;\\\\\\&#10;cot(x)+2\cdot \cfrac{sin(x)}{cos(x)}+\cfrac{sin^3(x)}{cos^3(x)}\implies \boxed{cot(x)+2tan(x)+tan^3(x)}

What are the x-coordinates for the maximum points in the function f(x)=4cos(2x-pi) from x=0 to x=2pi?
wel
The maximum value attained by the function will be 4
4 = 4cos(2x - π)
cos(2x - π) = 1
2x - π = 0
x = (nπ)/2
From x = 0 to x = 2π, n = 1, 2, etc
The equation will yield +4 for odd values of n and -4 for even values of n
