Which statement about the picture below is true

For a polygon with 10 sides, which equation below represents the sum of the interior angles in the polygon?

sum = (360)(8) = 2880°
sum = (360)(10) = 3600°
sum = (180)(8) = 1440°
sum = (180)(10) = 1800°

Answers

Correct answer is:

1800°

the correct answer is 1440.

The equation to find the sum of interior angles in a polygon is s = 180(n-2), n being the amount of sides and s being the sum. To solve you would do s = 180(10-2), s = 180(8), and s = 1440. hopefully that makes sense haha. use the equation s=180(n-2) :))

Step-by-step explanation:

but yass queen but annyway

Answer:

--Educate the general public about activities that can lead to the spread of invasive species.

--Implement conservation methods to restore endangered populations of native animals to the area.

Explanation:

Invasive species is the species which comes from non-native land either due to human introduction or by their own. The invasive species compete with the members of the native species for resources.

The following are the steps will help prevent the introduction of invasive species into an area:

--Educate the general public about activities that can lead to the spread of invasive species.: The general public must be aware about the drawbacks and problems associated with the spread of invasive species.

--Implement conservation methods to restore endangered populations of native animals to the area.: The invasive species is likely to compete with the native species for resources. Hence, this can harm the population of the native species. This will kill the native species members to the extend that the species become endangered. The endangered members must be protected by using the conservation methods.

Answers

Answer:

I would say A

Step-by-step explanation:

The price of the pizza and the number of toppings added is most likely show a positive correlation when graphed on a scatter plot.

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The data that will most likely show a positive correlation when graphed on a scatter plot is the price of the pizza and the number of toppings added.

As the number of toppings added to a pizza increases, the price of the pizza is likely to increase as well.

we can expect to see a positive correlation between these two variables when graphed on a scatter plot.

Hence, the price of the pizza and the number of toppings added is most likely show a positive correlation when graphed on a scatter plot.

Answers

Answer: For the first one, 12.5% chance

Step-by-step explanation:

The probability of flipping a coin and getting tails is 50%. Then, if you were to flip two coins and get both tails, you would have to divide the 50% by 2, which is equals to 25% of flipping two coins and getting them both tails.

So now we know...

Flipping one coin gives you 50% tails and 25% of flipping two coins and getting two tails

So now, we do it again with the third coin. We would divide the 25% by 2, which will get us to a 12.5% of getting all tails, or in fractions, 1/8

I’m not exactly sure about the other ones but I hope you found this one helpful!

1. It’s easiest to visualize if you write down all of the options that are possible when flipping a coin 3 times.
TTT
TTH
THT
THH
HHH
HHT
HTH
HTT
(i believe thats all of the options, if not adjust as needed)
but TTT is 1 out of the 8 possibilities, making the probability of getting three tails 1/8 or .125

2. There are two possibilities for getting a sum equal to three with two dice being rolled. Rolling a 1 and rolling a 2 or rolling a 2 and rolling a one.
You have 36 different combinations total, making your fraction 2/36

2/36 still needs to be simplified by dividing by two

your answer is 1/18 or .55555 repeating

3. There is no black section on the spinner so there is no way to land on a black section. The probability is 0

4. I believe this question is asking about the theoretical probability of flipping a coin, which is 1/2 or .5

5. You’ve got a theoretical probability of 3/6 or 1/2 chance to roll less than a four. If you roll the cube 24 times, you should expect to get 12 (half of 24) rolls less than four.

6. The probability of choosing a red marble is 5/30 or 1/6. The marbles are always replaced so your probability doesn’t change.

Noah pulls 60 marbles out and replaces them. 1/6 of those marbles should be red.

1/6 of 60 is 10

10 marbles should be red

7. There are 11 balls total. 5 of those are green (5/11), 3 of them are red (3/11), 2 of them are white (2/11), and 1 of the balls is orange (1/11).

The probability of choosing an orange ball (the least occurring) is 1/11 or .090909 repeating

8. Adrian has a 1/4 chance of being put in any singular section. He volunteers 20 times. We’re trying to figure out how many times he was put in either the cat or the reptile section.

If we add the probabilities of the cat and reptile assignment, you get 1/2.
1/2 of 20 is 10

Keeping the probabilities separate and adding the occurrences together at the end will give you the same answer.
1/4 of 20 is 5
Add another 1/4, which is 5+5 and it’s 10

9. Let’s label the four sections on the spinner 1, 2, 3, and 4. The outcome of the coin flip will either be heads or tails.

The combinations could be:

1 H
2 H
3 H
4 H
1 T
2 T
3 T
4 T

That totals to 8 possible outcomes.

You can multiply the two outcome numbers together to achieve the the same answer:

2(4) = 8

a wildlife manager determines that the function y=200x1.07* represents the deer population at a state park x years after the population is first counted. what is the population after 12 years? what is the initial population? what is the percentage rate? complete the table below.

Answers

Answer:

Table:

0,200

4, 262

8,344

12, 450

Population after 12 years is 450 deer

Initial population is 200 deer.

Step-by-step explanation:

You take the x in the table and plug it in as an exponent so you will need a calculator or multiple the 1.07 by that many times so 1.07 12 times multipled by itself. and the initial is 0 years so anything to the exponent of 0 is 1 so that show i got 200 for the x=0

(2c) Solve the equation: 6 = 1/2z

Answers

Answer:

z=12

Step-by-step explanation:

multiply both sides of the equation by 2

12=z

swap the sides of the equation

z=12

Answer:

You move all terms to the left;

6-(1/2z)=0

Domain of the equation: 2z)!=0

z!=0/1

z!=0

You add all the numbers together, and all the variables;

-(+1/2z)+6=0

You get rid of parentheses;

-1/2z+6=0

You multiply all the terms by the denominator;

6*2z-1=0

You multiply elements;

12z-1=0

You move all terms containing z to the left, all other terms to the right;

12z=1

z=1/12

And your answer is: z=1/12
