You flip three coins. what isthe probability that you get at least two heads, given that you get at least one head?

Pepsi [2]

1/2
If there is one head and one tail for each coin the probability would be 1/2. There are two terms with only one answer 1/2.

OR

If you are asking for the end result of heads and the coins you would get 2/3. There are three terms with only one answer. 2/3.

If 5/6 gallons of paint covers 1/4 of the house, then how much paint is needed for the entire house?

tia_tia [17]

Answer:

Step-by-step explanation:

1) If $\frac{5}{6}$ is needed to cover $\frac{1}{4}$ than we need 3 more: $\frac{5}{6}(3)=\frac{15}{6} =2\frac{3}{6} gallons2) But we still need to add the beginning [tex]\frac{5}{6}$ : $2\frac{3}{6}+\frac{5}{6}=2\frac{9}{6}=3\frac{3}6}=3.5$

1. A tennis tournament starts with 120 players. During each round of the game, half of the players are eliminated from the tourn

lorasvet [3.4K]

Answer:

Exponential function; $y=120(\frac{1}{2})^x$ .

Step-by-step explanation:

We have been given that a tennis tournament starts with 120 players. During each round of the game, half of the players are eliminated from the tournament.

We can see that the change in number of eliminated players is not constant. The number of players in tournament is decreasing exponentially. Therefore, an exponential function best models the relationship between the number of players in the tournament, y, and the game round, x.

We know that exponential decay function is in form $y=a(b)^x$ , where,

y = Final amount,

a = Initial amount,

b = Decay factor,

t = Time

Since during each round of the game, half of the players are eliminated from the tournament, so decay factor would be $\frac{1}{2}$ .

Initially there were 120 players, so $a=120$ .

Therefore, our required equation would be $y=120(\frac{1}{2})^x$ .
