Mathematics

Answer:

9/25 = 36/100 = 36% . . . . "out of" meaning "parts of"

25 - 9 = 16 . . . . "out of" meaning "from"

Step-by-step explanation:

The wording "out of" can be taken a couple of ways in this usage. Context is important, and no context is provided here.

Often, it means "parts of" as in 9 of 25 parts, or 9/25.

An equivalent fraction is 18/50 or 36/100 = 0.36 = 36%.

This would be the usual meaning in the context of probability.

This wording can also mean 9 parts taken from 25, so the remaining amount is 16. Equivalents might be 10 from 26, or 4 from 20.

Since the probability that 50% of the babies born are female, she could use any probability model that is 50/50.

For example, she could flip a coin. Or she could roll a die, using the even numbers for girls and odd numbers for boys.

Is 6/12 and 15/30 proportional?

sveticcg [70]

Answer:

yes

Step-by-step explanation:

6 is half of 12. 15 is half of 30. The ratios are equal, so the fractions are proportional.

Answer: yes

Also, you can reduce both fractions.

Divide the numerator and denominator of 6/12 by 6 to get 1/2.

Divide the numerator and denominator of 15/30 by 15 to get 1/2.

Since both fractions reduce to 1/2, 6/12 and 15/30 are equivalent fractions and are proportional.

5.3.4 Journal: Two-Variable Systems Elimination <br><br> I need urgent help

max2010maxim [7]

Answer:

1) X stands for individual acts and y, group acts. 2) Each scenario describes a different period in minutes, but each one respecting their different amounts (individual and group acts). 3) $S=\left \{ 5,10 \right \}$

Step-by-step explanation:

Completing with what was found:

<em> 1) Here is a summary of the scenario your classmate presented for the talent show:Main show The main show will last two hours and will include twelve individual acts and six group acts.Final show The final show will last 30 minutes and will include the top four individual acts and the top group act.The equations he came up with are: 12x+ 6y= 120, 4x+ y= 30</em>

1. What do x and y represent in this situation?

X stands for individual acts and y, group acts.

Besides that, In the system of equation, they represent the time for x, and the time for y.

2. Do you agree that your classmate set up the equations correctly? Explain why or why not.

Yes, that's right. Each scenario describes a different period in minutes, but each one respecting their different amounts (individual and group acts). Either for 120 minutes or 30 minutes length. And their sum totalizing the whole period.

3. Solving the system by Elimination

$\left\{\begin{matrix}12x+ 6y= 120\\ 4x+ y= 30\end{matrix}\right.\\\left\{\begin{matrix}12x+ 6y= 120\\ 4x+ y= 30\:*(-3)\end{matrix}\right.\\\left\{\begin{matrix}12x+ 6y= 120\\ -12x+ -3y= -90\end{matrix}\right.\\3y=30\Rightarrow y=10\\4x+(10)=30\Rightarrow 4x=20\Rightarrow x=5\\S=\left \{ 5,10 \right \}$
