Please Help!

The graph shows the vertical displacement y, in centimeters, that a weight bouncing from a spring would achieve if there were no friction, for a given number of seconds, x.

From its resting position, how long does it take the weight to bounce one direction, then the other, and then return to its resting position?

-3s
-6s
-16s or
-32s

Sure.

See above

I believe this is correct, hope it helps.

Answer:

It gets bigger

Step-by-step explanation:

You just multiply the circumference by 3

Answer:

The circumference is tripled

Step-by-step explanation:

The formula for the circumference is 2πr. If you triple the radius the formula would be 2π3r. the ratio between the two is 2π3r / 2π1r. 2π & r cancels out and you have 3/1 left. Therefore the answer is the circumference is tripled.

The fact that there is no exponential in the formula indicates that the proportional increase is lineal.

ED/AB = 5/5 = 1

The scale factor from ΔABC to Δ DEF is, 1

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

We have to given that;

The figure of ΔABC to Δ DEF is shown in image.

Now, We can formulate for the scale factor,

⇒ AB / DE

⇒ 5 / 5

⇒ 1

Thus, The scale factor from ΔABC to Δ DEF is, 1

Answer:

5 miles

Step-by-step explanation:

If Tara lives 3/4 miles from the park and Nikhil lives 6 2/3 as far, then you must multiply them together: 3/4*6 2/3 = 3/4*20/3

Solve: 3/4*20/3=5

Therefore, Nikhil lives 5 miles from the park.

The miles that Nikhil lives from the park given the miles that Tara lives from the park is 5 miles.

A fraction is a number that has a numerator and a denominator. The numerator is the number above and the denominator is the number below.

Multiply 3/4 by 6 2/3

3/4 x 6 2/3

3/4 x 20/3 = 5 miles

Using the binomial distribution, it is found that there is a 0.957 = 95.7% probability that he sells less than 3 cars.

The formula is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem:

The probability he sells less than 3 cars is:

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2).

In which:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{16,0}.(0.05)^{0}.(0.95)^{16} = 0.4401[/tex]

[tex]P(X = 1) = C_{16,1}.(0.05)^{1}.(0.95)^{15} = 0.3706[/tex]

[tex]P(X = 2) = C_{16,2}.(0.05)^{2}.(0.95)^{14} = 0.1463[/tex]

Then:

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.4401 + 0.3706 + 0.1463 = 0.957.

0.957 = 95.7% probability that he sells less than 3 cars.

Step-by-step explanation:

The distribution of the animals in the coral reef is an illustration of probability

The distribution of the animals is given as:

Blue fish = 3

Yellow fish = 7

Sea turtle = 1

Eels = 3

The animal with the highest frequency is the most likely animal.

Hence, the Yellow fish is the most likely animal.

From the question, we have:

Blue fish = 3

Eels = 3

Both animals have the same frequency.

This means that Riley has equal chance of seeing a blue fish and an eel.

The animal with fins are:

Blue fish = 3

Yellow fish = 7

So, the probability is:

[tex]p = \frac{3 + 7}{3 + 7 + 1 + 3}[/tex]

[tex]p = \frac{10}{14}[/tex]

Simplify

[tex]p = \frac 57[/tex]

Hence, the probability of seeing an animal with fins is 5/7

The animal with the least frequency is:

Sea turtle = 1

So, the likelihood is:

[tex]p = \frac 1{14}[/tex]

Hence, the sea turtle has the least likelihood of 1/14

The Blue fish and the Eels have the same frequency of 3

This means that animals have equal likelihood

We have:

Blue fish = 3

Yellow fish = 7

Sea turtle = 1

Eels = 3

Express as probability

Blue fish = 3/14

Yellow fish = 7/14

Sea turtle = 1/14

Eels = 3/14

Express the fractions as decimals

Blue fish = 0.214

Yellow fish = 0.500

Sea turtle = 0.071

Eels = 0.214

So, their likelihoods are:

Blue fish = Equally likely

Yellow fish = Certainly likely

Sea turtle = Unlikely

Eels = Equally likely

Answer:

Step-by-step explanation:

In Rhombus opposite angles are equal.

6x + 8 = 86

6x = 86 - 8   {Subtract 8 from both sides}

6x = 78

x = 78/6  {Divide both sides by 6}

x = 13

In rhombus adjacent angles are supplementary.

7y + 3  + 86 = 180

7y + 89 = 180

      7y = 180 - 89   {Subtract 89 form both sides}

      7y = 91

        y = 91/7  {Divide both sides by 7}

y = 13

5z + 4 + 86  = 180

     5z  + 90 = 180

            5z    = 180 - 90  {Subtract 90 from both sides}

             5z   = 90

                z = 90/5    {divide both sides by 5}

z = 18

Answer:

y = -7x -7

explanation:

y - y₁ = m ( x - x₁ )

y - -7 = -7 ( x - 0 )

y + 7 = -7x

y = -7x -7

Or using the formula:

y = mx + b

y = -7x - 7

using this formula, if only passes y-axis, we can find equation without doing any work.

Answer:

The system of equations:

Nancy:   Y=$425+$25x

Sam :   Y=$705-$15x

Given:

Amount in Nancy's bank = $425

Amount saved by Nancy each week = $25

Amount in Sam's bank = $705

Amount spent by Sam each week = $15

To find:

Y=$425+$25xx

Y=$425+$25x

The system of equations describing the given models.

Solution

1) Amount in Nancy's bank = $425

Amount saved by Nancy each week = $25

Let the number of weeks Nancy saving her money be 'x'.

Let the total amount of money in Nancy's bank after x weeks be 'y'.

The equation for Nancy: Y=$425+$25x

2) Amount in Sam's bank = $705

Amount spend by Sam each week = $15

Let the number of weeks Sam spending his money be 'x'

Let the total amount of money left in Sam's bank after x weeks ='y'

Answer:

8.25*10^24

Step-by-step explanation:

1000*.25= 250 (this converts the .25 into milliliters)

250(3.3 * 10^22)

= 8.25*10^24

The required molecules of water in the glass are given as 8.25 × 10²⁴.

Unit of measurement is defined as every entity having its measures in dimensions, weight, and time. Such as for length we have a meter, for liquid we have liters, and so on.

Here,
A glass of water contains 0.25 liter of water.
1 liter = 1000 mililiters
So,

0.25 liter = 250 mililiter

Now,
1 milliliter of water contains 3.3 x 10²² water molecules,
Number of molecules in 0.25 liters of water,
= 250 × 3.3 x 10²²
= 8.25 × 10²⁴

Thus, the required molecules of water in the glass are given as 8.25 × 10²⁴.
