Answer:

Step-by-step explanation:

The area of a triangle is

$A=\frac{1}{2}bh$ and we have the base (12m) and we need to find the height. Using Pythagorean's Theorem:

$6^2=4^2+h^2\\36=16+h^2\\20=h^2\\h=2\sqrt{5}$

That's the height that we will sub into the area formula:

$A=\frac{1}{2}(12)(2\sqrt{5})\\A=12\sqrt{5}\\A=26.8$

Lucy offers to play the following game with Charlie: "Let us show dimes to each other, each choosing either heads or tails. If w

Darya [45]

Answer:

(a)Charlie is right

(b)$0

Step-by-step explanation:

(a)A game is said to be a fair game when the probability of winning is equal to the probability of losing. Mathematically, a game is said to be fair when the expected value is zero.

In the game, the possible outcomes are: HH, HT, TH and TT.

Charlie wins when the outcome is HH, TT

P(Charlie Wins)=2/4
P(Charlie Losses)=2/4

Lucy wins when the outcome is HT or TH

P(Lucy Wins)=2/4
P(Lucy Losses)=2/4

Therefore, the game is fair. Charlie is right.

(b)

If the outcome is HH, Lucy pays $3.

If the outcome is HT or TH, Lucy gets $2.

If the outcome is TT, Lucy pays $1.

The probability distribution of Lucy's profit is given below:

$\left|\begin{array}{c|c|c|c}$Profit(x)&-\$3&-\$1&\$2\\P(x)&1/4&1/4&2/4\end{array}\right|$

Expected Profit

$=(-3 \times \frac14)+(-1\times \frac14)+(2 \times \frac24)\\=$0$

Lucy's expected profit from the game is $0.

Let t[1..n] be a sorted array of distinct integers, some of which may be negative. give an algorithm that can find an index i su

lisabon 2012 [21]

Assuming we need to find i such that
1 ≤ i ≤ n and t[i]=i.

If we need to find only the first occurrence, we can do:

for i:1 to n {
if t[i]=i then return(i)
}

If exhaustive search is required, then put the results (values of i) in an array or a linked list, return the number of values found, and the array (or linked list).
