(H, H, T) represents X

Step-by-step explanation:

If a coin is tossed the outcome is either Heads or Tails.

If 3 coins are tossed, then the total no. Of outcomes are 8 .

The outcomes are,

(H, H, H), (H, H, T), (H, T, H), (H, T, T), (T, H, H), (T, H, T), (T, T, H), (T, T, T)

The outcome represented by X is heads on the first coin, heads on the second coin, and tails on the third coin.

46 is 92 percent of what number

Vladimir79 [104]

1. We assume, that the number 92 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for. 
3. If 100% equals 92, so we can write it down as 100%=92. 
4. We know, that x% equals 46 of the output value, so we can write it down as x%=46. 
5. Now we have two simple equations:
1) 100%=92
2) x%=46
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=92/46
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 46 is what percent of 92

100%/x%=92/46
(100/x)*x=(92/46)*x - we multiply both sides of the equation by x
100=2*x - we divide both sides of the equation by (2) to get x
100/2=x 
50=x 
x=50

now we have: 
46 is 50% of 92

Factor the following polynomial. 2x^3– 10x^2 – 12x Enter the GCF of the polynomial.

olga_2 [115]

The equation $2x^{3} -10x^{2} -12x$ has 2 and x in common. This means you can factor both the 2 and x out of the equation like so...

2x( $x^{2} -5x-6$ )

Hope this helped!

A person standing cloes to the edge on the top of a 200-foot building throws a baseball vertically upward. The quadratic functio

RoseWind [281]

Answer:

See below in bold.

Step-by-step explanation:

A). s(t)= -16t^2+64t+200

Converting to vertex form.

s(t) = -16 (t^2 - 4t) + 200

s(t) = -16 [(t - 2)^2 - 4] + 200

s(t) = -16(t - 2)^2 + 64 + 200

s(t) = -16(t - 2)^2 + 264

The maximum height is after 2 seconds and it is 264 feet.

B) The ball hits the ground when s(t) = 0 so we have:

-16t^2+64t+200 = 0

x [-64 +/- sqrt (64^2 - 4*-16*200) ] / -32

x = 6.06, -2.06

So the answer is 6.06 seconds.
