Answer:3.2

Step-by-step explanation: add them all up and divide by the sample size.

Answer:

The average number of cavities is 3.2

Step-by-step explanation:

To find the answer we will put them in order from least to greatest.  

0, 1, 4, 5, 6.  Now add all the numbers up and we get 16.  Because we are trying to find the average number, we will count up how many numbers there are.  Since their are 5 numbers total, we divide 16 by 5 and we get 3.2.  Therefore, 3.2 is our answer.

Answer:

  A.  r = 4

Step-by-step explanation:

For common ratio r, the second term is ...

  a2 = 3r

The next terms are ...

  a3 = (a2)r = (3r)r = 3r²

  a4 = (a3)r = (3r²)r = 3r³ = 192

Then the value of r is ...

  r³ = 192/3 = 64

  r = ∛64 = 4

The common ratio is r = 4.

Answer:

No, they cannot be becuase the points are too different- no same numerical

values.

Step-by-step explanation:

The equation is f(x) = x² – 8x + 5. Then the y-intercept is at (0, 5) and the function crosses the x-axis twice. Then the correct options are A, D, and E.

Let the point (h, k) be the vertex of the parabola and a be the leading coefficient.

Then the equation of the parabola will be given as,

y = a(x - h)² + k

The quadratic equation is given below.

f(x) = x² – 8x + 5

Convert the equation into vertex form, then the equation will be

f(x) = x² – 8x + 5

f(x) = x² – 8x + 16 – 16 + 5

f(x) = (x – 4)² – 16 + 5

f(x) = (x – 4)² – 11

The graph of the function is given below.

From the graph, the y-intercept is at (0, 5) and the function crosses the x-axis twice.

Then the correct options are A, D, and E.

hello how have u been?

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Given the 2 equations

3x + 2y = 4 → (1)

- 2x + 2y = 24 → (2)

Multiplying (2) by - 1 and adding to (1) will eliminate the y- term

2x - 2y = - 24 → (3)

Add (1) and (3) term by term to eliminate y

5x + 0 = - 20

5x = - 20 ( divide both sides by 5 )

x = - 4

Substitute x = - 4 into either of the 2 equations and solve for y

Substituting into (1)

3(- 4) + 2y = 4

- 12 + 2y = 4 ( add 12 to both sides )

2y = 16 ( divide both sides by 2 )

y = 8

solution is (- 4, 8 ) → C

Answer:

12 years

Step-by-step explanation:

Represent the mother's age by m and the son's by 4.  Currently m = 36 years old.

In x years the mother will be three times as old as her son:

mother:  36 + x years old

son:  4 + x years old

The pertinent equation to solve is:

36 + x = 3(4 + x)

Performing the multiplication, we get:

36 + x = 12 + 3x, or

24 = 2x.  Then x = 12.

Check:  In 12 years, will the mother's age be 3 times the son's age?

Does 36 + 12 = 3(4 + 12)?

Does    48      = 48?  YES

The mother will be 3 times as old as her son in 12 years from now.

Answer:

(5,45)

Step-by-step explanation:

Hi,

y = 2x + 35

y = 9x

To solve, we can substitute 9x for y.

9x = 2x + 35

Subtract 2x...

7x = 35

Divide by 7...

x = 5

Now plug in 5 for x...

y = 9x

y = 9(5)

y = 45

Your answer is (5,45)

I hope this helps :)

Answer:

x=5, y=45. (5, 45).

Step-by-step explanation:

y=2x+35

y=9x

-------------

2x+35=9x

35=9x-2x

35=7x

x=35/7

x=5

y=9(5)=45

Step-by-step explanation:

2x+10=5x−2

Subtract 5x from both sides

2x+10−5x=−2

Combine 2x and −5x to get −3x.

−3x+10=−2

Subtract 10 from both sides.

−3x=−12

Divide both sides by −3.

Divide −12 by −3 to get 4.

[tex]28x+8y+2[/tex]

Step-by-step explanation:

The function equation represented by the graph is given by the following variable f ( x ) = 5 ( 2/5 )ˣ

Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.

Identify the even and odd multiplicities of the polynomial functions' zeros.

Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.

The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities

Given data ,

Let the equation of graph of the function be represented as A

Now , the value of A is

The function is an exponential equation with intercepts at

Let the first point on the graph be A ( 0 , 5 )

Let the second point on the graph be B ( 1 , 2 )

Now , the line is an exponential decay equation of the form

A = 5 ( 2/5 )ˣ

Therefore , the function is f ( x ) = 5 ( 2/5 )ˣ

Hence , the equation of graph is A = 5 ( 2/5 )ˣ and it is plotted
