Answer:

When 0< x < 5,  |x - 5| = 5 - x  and  |x+5| = x + 5.  Summed, we get y = 10

When -5< x < 0, |x - 5| = x - 5 and   |x+5| = 5 - x. Summed, we get y = 10.

Combined, y = 10.

When O< x < 5, Ix - 5| = 5 - x and Ix+5| = x+
5. Summed, we get y = 10
When -5x. Summed, we get y = 10.
Combined, y = 10.

Which ratio best defines experimental probability?

Number of times an event occurs: Total number of times the activity is performed
Total number of times the activity is performed: Number of times an event occurs
Number of nonfavorable outcomes: Number of possible outcomes
Number of possible outcomes: Number of nonfavorable outcomes

Answers

Answer:

Number of times an event occurs : Total number of times the activity is performed

Step-by-step explanation:

Experimental probability is the probability of an event occurring based on actual experimental results, whereas theoretical probability is the expected probability of an event occurring.

For example, the theoretical probability of flipping a coin and it landing on a head is 1/2.  

If we carried out an actual experiment where we flipped the coin 20 times, recorded the results, and only 5 of the flipped coins landed on heads, then the experimental probability of the coin landing on a head would be 5/20 = 1/4.

The more trials we carry out, the closer the experimental probability gets to the theoretical probability.

Therefore, the best definition of experimental probability is:

Number of times an event occurs : Total number of times the activity is performed

Answer:

Answer:Number of times an event occurs : Total number of times the activity is performedStep-by-step explanation:Experimental probability is the probability of an event occurring based on actual experimental results, whereas theoretical probability is the expected probability of an event occurring.For example, the theoretical probability of flipping a coin and it landing on a head is 1/2.  If we carried out an actual experiment where we flipped the coin 20 times, recorded the results, and only 5 of the flipped coins landed on heads, then the experimental probability of the coin landing on a head would be 5/20 = 1/4.The more trials we carry out, the closer the experimental probability gets to the theoretical probability.Therefore, the best definition of experimental probability is:Number of times an event occurs : Total number of times the activity is performed

A cell phone provider offers a plan that costs ​$40 per month plus ​$0.10 per text message sent or received. A comparable plan costs ​$60 per month but offers unlimited text messaging. If you send or receive an average of 50 text messages each​ month, which plan would you​ choose? Why?

Answers

Okay so $40 a month, 10 cents per message.

10 cents times 50 messages is only 5 dollars.

So, it would be around $45 a month.

If I only sent around that many messages a month, I would just go with the $40 a month, cause you can save around $15.

Answer:

[tex]4 \frac{13}{30}[/tex] (4 13/30)

Steps :

1) Convert 1 1/6 and 3 4/5 to mixed numbers.

1 1/6 is 7/6 in mixed number and 3 4/5 is 19/5 in mixed number.

2) multiply 7/6 x 19/5, which is 7 x 19/6 x 5.

7 x 19 is 133 and 6 x 5, so it would be 133/30

3) Change 133/30 to a mixed number, which would be [tex]4\frac{13}{30}[/tex] ( 4 13/30)

To get the answer, you need to do 133/30, which is 4.43333, witch would be 4 13/30 ([tex]4\frac{13}{30}[/tex])

Sarah works at an electronic store. She earns 17% commission on everything she sells. If Sarah sold $38,000 worth of items this month, what is her commission for the month?

Answers

Answer:

$6,460

Step-by-step explanation:

I like to do it the long way, but I think it makes the most sense;

Divide 38k by 100 to get 1% of her amount (because 38k is 100%)

38000/100 = 380

Now multiply that number by 17 to get 17% because 380 is 1%, already determined above.

So thus 380*17 is  6460
