C)  2

Mean of the given distribution = 2

Step-by-step explanation:

Explanation:-

Given data from histogram

1 , 4, 5 ,4 ,2, 1, 1 , 1, 1,0

Mean of given data

                             = ∑x / n

Given  n = 10

[tex]Mean = \frac{1+4+5+4+2+1+1+1+1+0}{10} = \frac{20}{10} =2[/tex]

Mean of the given distribution = 2

Answer:

y = 4[tex](3)^{x}[/tex]

Step-by-step explanation:

For an exponential function in the form

y = a [tex]b^{x}[/tex]

Use the given points to find the values of a and b

Using (1, 12), then

12 = ab → (1)

Using (2, 36), then

36 = ab² → (2)

Divide (2) by (1)

[tex]\frac{36}{12}[/tex] = [tex]\frac{ab^2}{ab}[/tex] , then

3 = b

Substitute b = 3 into (1) for value of a

12 = 3a ( divide both sides by 3 )

4 = a

Thus

y = 4[tex](3)^{x}[/tex] ← is the exponential function

Answer:

x = 2

y = -1

Step-by-step explanation:

-(2) - y = -1

add 2

-y = 1

divide by -1

y = -1

Answer:

Step-by-step explanation:

You know the total will be $70.

She bought food, let's call that "F"

She spent $26 more on clothes than food. So her clothes purchase is "F+26".

So let's set-up the equation this way:

food + clothing = Total Spent

F + F + 26 = 70

2F + 26 = 70 (subtract 26 from both sides of the = sign)

2F = 44 (Divide both sides so you find out how much was spent on "F" or food.)

F = 22 (But the question doesn't stop there.)

Deborah spent $22 on food. (Remember, she spent $26 more on clothes, so we have to use our "clothes" equation? ) Deborah spent $48 on clothes. She spent a total of $70 on her purchases.

Answer:

To find the inverse you switch x and y

Step-by-step explanation:

3y-4x=6

So 3y = 4x+6

and Y = 4/3x + 2

Answer:

y=(6-3x)/-4

Step-by-step explanation:

to get the inverse we make y the subject of the equation

3x-4y=6

-4y=6-3x

y=(6-3x)/-4

Answer:

$20 + $15m ≥ $80

Step-by-step explanation:

He starts off with $20.

He adds $15 each month, so $15m.

He wants to save at least $80, which means greater than or equal to $80. So, you use this symbol: ≥

Put it all together.

$20 + $15m ≥ $80

Answer:

$48

Step-by-step explanation:

you would first need to find what the cost of 1 book is so

16 divided by 4 is 4

so 1 book is $4

then you would need multiply the cost of one book by 12

so 4 times 12 is 48

so the cost would be $48

Answer:

s = -1

Explanation:

s − (−20) = 19

[ Simplify both sides of the equation ]

s + 20 = 19

[ Subtract 20 from both sides ]

s + 20 − 20 = 19 − 20

s = −1

Answer:

x=0, y=0

Step-by-step explanation:

① Label the 2 given equations.

x -2y= 0 -----(1)

3x +y= 0 -----(2)

② Make x the subject of formula in equation (1).

From (1): x= 2y -----(3)

③ Substitute equation (3) into (2):

3(2y) +y= 0

Expand:

6y +y= 0

Simplify:

7y= 0

y= 0

④ Find x.

Subst. y=0 into (3):

x= 2(0)

x= 0

Answer:

  C.  graph Y

Step-by-step explanation:

Starting with f(r) = -3r +3, the inverse function can be found from ...

  r = f(y)

  r = -3y +3

  r -3 = -3y

  (r -3)/-3 = y

  y = -1/3r +1

The inverse function will have a slightly negative slope and a y-intercept of 1. This matches graph Y.

Answer:

19.25

Step-by-step explanation:

The number which is 4 x 10^3 times equal to the number 16 x 10^3 after is number 4.

Product is the resultant number which is obtained by multiplying a number with another. Let a number a is multiplied by number b. Then the Product of these two number will be,

[tex]P=a\times b[/tex]

Here, (a, b) are the real numbers.

The 4 x 10^3 times a number is equal to the number 16 x 10^3 Let suppose this number is n. Thus,

[tex]4\times10^{3}\times n=16\times10^{3}[/tex]

Divide both side of the equation with 4 x 10^3 as,

[tex]n=\dfrac{16\times10^{3}}{4\times10^{3}}\\n=\dfrac{16}{4}\\n=4[/tex]

Hence, the number which is 4 x 10^3 times equal to the number 16 x 10^3 after is number 4.
