Answer:

<h2>a) Número de personas que suben a un autobús en una parada.</h2><h2>c) Conocer el ganador de la Liga de Campeones.</h2>

Step-by-step explanation:

This problem is about random experiments.

Random experiments are defined as experiments where the outcome can't be predicted. To ensure that result, the subjects are selected randomly. So, in this case, the right answer must be a situation where subjects are randomly present.

People taking the bus is a random experiment, because there's no the exact subjects in a bus at any time, it happens randomly.

Also, the winner of a sport league is also a random experiment, because it happens after several games which cannot be predicted.

Therefore, the right answers are a and c.

Paha777 [63]

Answer:

$1,300

Step-by-step explanation:

commission on the first $10,000

= 4/100 * 10000

= $400

remaining amount

= $28,000 - $10,000

= $18,000

commission on remaining $18,000

= 5/100 * 18000

= $900

total commission

= $400 + $900

= $1,300

Which are solutions of the equation x^2- 16 = 0? Check all that apply
stealth61 [152]

Answer:

x= -4

x= 4

Step-by-step explanation:

This is a quadratic equation, and can be solved very quickly since it only has two terms, the square one and the free term.

Hence the solutions is obtained following the steps from below:

x2-16=0

Lets sum to both side 16

x2-16=0+16

x2=16

Now, lets apply square root to whole equation:

\sqrt{x^{2} }=\sqrt{16}

x=|4|

The bars means that x can be-4 o 4, since -4^2=16 and 4^2=16
