Um terreno retangular possui o comprimento cinco vezes maior que a largura. Sabendo que o perímetro desse terreno é igual a 180
icang [17]

Responder:

15 m e 75 m

Explicação passo a passo:

Deixar :

Largura = x

Comprimento = 5x

Perímetro = 180

Já o terreno tem uma forma retangular; usamos a relação;

Perímetro = 2 (comprimento + largura)

180 = 2 (5x + x)

180 = 2 (6x)

180 = 12x

180/12 = x

15 = x

Largura = x = 15 metros

Comprimento = 5x = 15 * 5 = 75 metros

Medida de largura e comprimento, respectivamente:

15 m e 75 m

In each turn of a game you toss two coins. if 2 heads come up, you win 2 points and if 1 head comes up you win 1 point. if no he
Blizzard [7]

The expected value of the number of points for each turn is 0.25

<h3>What is expected value?</h3>

Expected value describes the long term average level of a random variable based on its probabilty distribution.

Now, Probability that 2 heads come up is

P(2 is H) = 1/4

Probability that 1 heads come up is

P(1 is H) = 2/4

⇒P(1 is H) = 1/2

Probability that no head will come up

P(no H's) = 1/4

Hence, the expected value for winning of 2points, 1point and  lose of3 points is given as-

Expected value = 2 * P(2 is H) + 1 * P(1 is H)  - 3 * P(no H's)

⇒Expected value = 2 * 1/4 + 1 * 1/2 - 3 * 1/4

= 0.5 + 0.5 - 0.75

⇒Expected value = 0.25
