A soccer goalie can block 3/5 of the opposing team's shots. Suppose there are 20 attempted blocks in a soccer game. Which can be

used to simulate the results of the goalie's attempted blocks?
A. You can flip a coin. Heads means the goalie successfully blocked the shot and tails means the goalie missed the block.

B. You can draw a card with replacement from a standard deck. A red heart card means the goalie successfully blocked the shot and a card other than a red heart means the goalie missed the block.

C. You can roll a 6-sided dice. Rolling a number less than 5 means the goalie successfully blocked the shot and rolling 5 or 6 means the goalie missed the block.

D. You can draw marbles with replacement from a bag with 6 red marbles and 4 black marbles. A red marble means successfully blocked the shot and a black marble means the goalie missed the block.

se vendieron 144 boletos. 2 pesos por adulto y un peso por niño, si se gastaron 207 pesos cuantos boletos de adulto se vendieron
natulia [17]

Answer:

Se vendieron 81 boletos de niños y 63 boletos de adultos.

Step-by-step explanation:

La cantidad de boletos vendidos es igual a:

144 = a + n   (1)

En donde <em>a </em>es por adultos y <em>n</em> por niños

A su vez, el dinero gastado equivale:

207 = 2*a + 1*n   (2)

Resolviendo la ecuación (1) para <em>a:</em>

a = 144 - n   (3)

Introduciendo (3) en la ecuación (2) tenemos:

207 = 2*(144 - n) + n

n = 81

Ahora podemos calcular el numero de boletos de adultos vendidos introduciendo <em>n</em> en la ecuación (3):

a = 144 - n = 144 - 81 = 63

Entonces, se vendieron 81 boletos de niños y 63 boletos de adultos.

In a class there are 40 students 30 are boys and what is the percentage of girls ....​
Artyom0805 [142]

Answer:

25%

Step-by-step explanation:

Total= 40 students

boys +girls= 40

30 +girls= 40

number of girls

= 40 -30

= 10

Percentage of girls

=  \frac{10}{40}  \times 100\% \\ =  25\%

Alternatively,

percentage of girls

= 100% -(percentage of boys)

= 100\% - ( \frac{30}{40}  \times 100\%) \\  = 100\% - 75\% \\  = 25\%
