Which of the sets of ordered pairs represents a function?

A = {(−5, 5), (−2, 2), (2, −2), (5, −5)}

B = {(4, 2), (3, −2), (9, 4), (11, −3)}

Only A
Only B
Both A and B
Neither A nor B

Answers

Answer 1

Answer:

Both A and B

Step-by-step explanation:

A set of ordered pairs is not a function if there is a repeating output (Y value.)

Y values of A= 5, 2, -2, -5.

Y values of B= 2, -2, 4, -3.

There are no repeating outputs.

A coin lands on heads 300 times. The relative frequency of heads is 0.6. How many times was the coin flipped?

Answers

Answer: Number of times the coin is flipped =500

Step-by-step explanation:

Relative frequency of head = [tex]\dfrac{\text{Number of times heads occur}}{\text{Total number of times coin is flipped}}[/tex]

Let x= Number of times the coin is flipped, then

[tex]0.6=\dfrac{300}{x}\\\\\Rightarrow\ x=\dfrac{300}{0.6}\\\\\Rightarrow\ x=\dfrac{3000}{6}\\\\\Rightarrow\ x=500[/tex]

Hence, Number of times the coin is flipped =500

Answers

Answer:

Number line graph with closed circle on 24 and shading to the right.

Step-by-step explanation:

First, the graph has to have a closed circle on only 24.

Since she has $61 and needs at least $85 to buy a skateboard, she needs to have at least $24 saved to buy one.

This means the last 2 answer choices are wrong, because there cannot be shading in between.

The first answer choice is also wrong because it puts a open circle, instead of a closed one, on 24.

So, the correct answer is Number line graph with closed circle on 24 and shading to the right.

Answers

Answer:

  $14

Step-by-step explanation:

Computing 40% can be done a couple of ways.

  40% = 40/100 = 4/10 = 2/5

  40% of 35 = (2/5)(35) = 2(35/5) = 2(7) = 14

__

  40% = 4/10 = 2(2(1/10))

  40% of 36 = 2(2(1/10)(35)) = 2(2(3.5)) = 2(7) = 14

The amount discounted is $14.

m3 = 103 degrees

Step-by-step explanation:

comment if you want me to explain please :)

The interior angles of ∆AUL (or any triangle for that matter) sum to 180°, so

∠3 + 20° + 57° = 180°

===>   ∠3 = 103°

Angles ∠3 and ∠4 occur on the same ray LP, so they are supplementary to one another. In other words,

∠3 + ∠4 = 180°

so that

∠4 = 180° - 103° = 77°

You deposit $500 in an account that earns 6.5% annual interest compounded yearly. Write a function that represents the balance y (in dollars) after x years.

Answers

Answer:

f(x)=.65+y

Step-by-step explanation:

               .

The function for compound interest is A = 500 ( 1.065 )ˣ

What is Compound Interest?

Compound interest is interest based on the initial principle plus all prior periods' accumulated interest. The power of compound interest is the ability to generate "interest on interest." Interest can be added at any time, from continuously to daily to annually.

The formula for calculating Compound Interest is

A = P ( 1 + r/n )ⁿᵇ

where A = Final Amount

P = Principal

r = rate of interest

n = number of times interest is applied

b = number of time periods elapsed

Given data ,

Let the compound interest amount be represented as A

Now , the interest rate r = 6.5 %

The number of times the interest is applied = yearly

The principal amount P = $ 500

n = 1 ( compounded yearly )

t = x ( number of years )

So, the function that represents the balance y (in dollars) after x years is:

y ( x ) = 500 ( 1 + 0.065/1 )ˣ

On simplifying , we get

y ( x ) = 500 ( 1.065 )ˣ

Hence , the function is A = 500 ( 1.065 )ˣ

A human heart beats an average of 80 beats per minute. How many beats is this in an hour?

Answers

Answer:

4800 beats an hour

Step-by-step explanation:

there are 60 minutes in and hour

the heart beats 80 times per minute( that is actually a very high heart rate)

80*60=4800 per hour

I believe the answer is an average of 4800 beats per hour.
We know that the heart beats an average of 80 beats per minute and there are 60 minutes in an hour. We can use this information and multiply 80x60 to find the average amount of heartbeats in an an hour.

3 times the length of a field increased by 4 times the width gives 24 units. Two times the length decreased by 3 times the width is -1 unit. Find the dimensions

Answers

Answer:

width = 3

length = 4

Step-by-step explanation:

Ok so you can form a system of equations where w is the width and l is the length:

3l + 4w = 24

2l - 3w = -1

you want to eliminate one of the variables and then solve, so you can first take the top equation and multiply both sides by 2:

6l + 8w = 48

next, multiply the second equation by 3:

6l - 9w = -3

now that both include 6l, you can subtract the two equations

6l + 8w = 48

- (6l - 9w = -3)

17w = 51

divide both sides by 17

w = 3

Plug w = 3 into the equation 3l + 4w = 24:

3l + 4 * 3 = 24

3l + 12 = 24

subtract 12 from both sides

3l = 12

divide both sides by 3

l = 4

NEED HELP 70 PONITS... For the Birds!The Endangered Species Act was passed by Congress in 1973 to protect animals and plants that were at risk of becoming extinct. The following editorial appeared in a local newspaper in North Carolina in 1937a birdDear Citizens of Triston,As a concerned citizen of Triston and member of the North Carolina Conservation of Nature Council, I am asking for the community's help with a serious issue. First, I want to congratulate our town's mayor and city council for planning to build a new community theater. However, do they realize that building the theater on Asbury Woodlands will destroy the prime breeding ground for an endangered species?The Bachman's warbler is a small bird about four inches in length. This green-backed bird has a bright yellow belly and face and is sometimes confused with the similarly colored hooded warbler.Since 1897, the population of the Bachman's warbler has decreased from over 500,000 to fewer than 100 in North Carolina. The main reason is the destruction of the areas (like Asbury Woodlands) that it uses for its natural breeding grounds. Bachman's warblers prefer thickly wooded swamps and wet thickets in heavy, full-grown forests where they can build their nests and feed on insects.This does not mean that we cannot build a community theater. A similar situation recently arose in Cape Pristo, North Carolina. Nobel Hotels canceled its plans to build a high-rise structure when it became known that the roseate tern, another endangered bird, was living in the suggested location. Nobel Hotels put up a new building several miles down the beach from the original location, and the roseate tern kept its habitat.Our community has forever prided itself on caring for our natural surroundings. The city council has promised that the proposed theater will be "highly tasteful" and that the structure will "complement the spirit of our town."The city council's honorable concern for the endangered Bachman's warbler would smooth the feathers of many voters. With their help and the support of our townspeople, future generations will appreciate the beauty of this little bird.Sincerely,Redmond HarrisThe last sighting of the Bachman's warbler in the United States was in 1988, and the last warbler nest was found in 1937 in Alabama.3Select the correct answer.Which audience does the passage most likely address?A. people of North Carolina B. animal activist groupsC.
