I don’t understand this

Mathematics

The answer is 1/20. This is probability. <u><em>probability is the chance of you picking a certain thing</em></u>. for example: You have 3 blue marbles, 6 red marbles, and 4 purple marbles. the probability of pick a blue marble is 3/13. A red would be 6/13, and a purple would be 4/13.

So what this is asking is what are the chances that something will happen over something will not happen. the said that "the probability that an event will not happen is P(E') = 19/20. if you are having a lot of trouble with this, try removing the events with something like marbles (Something you have done before) this tends to make it a little easier to read.

wo neighboring homeowners, , 2, simultaneously choose how many hours to spend maintaining a beautiful lawn. The average benefit
Fantom [35]

To calculate the average benefit of hours we must add all the values then divide by the number of values that we have.

<h3>What is the average?</h3>

Average is a term that refers to a value that represents the mean of a group of values. For example, if my friends and I have a race to run from point A to point B and our times are:

  • 69 seconds.
  • 58 seconds.
  • 45 seconds.
  • 120 seconds.
  • 76 seconds.

The average time of my group of friends would be:

69 + 58 + 45 + 120 + 76 = 368

358 ÷ 73.6 seconds

The average of my group of friends would be 73.6 seconds.

According to the above, to identify the average profit per hour of my neighbors who own their lawns, you must use the same formula to obtain the result.

Note: This question is incomplete because the are some information missing. However I can answer it based on my prior general knowledge.

Find an angle between 0 and 2pi coterminal with 35pi/6
Leona [35]
For the answer to this question, we have to solve it step by step.
We have to divide both sides by 35.<u>
35π</u> = <u>35(180)</u><u>
</u> 35        35
<u>
</u>= 1050°

1050° - 360° - 360° = 330°
If you would graph it, it would be -30 ° and it is coterminal

I hope my answer helped you somehow
