Answer:

28 or 28.11111 because I don't know if it asked you to round or not.

Step-by-step explanation:

Mean is the average of a group of number added together and divided by the number of number there are.

20+22+25+28+29+30+32+33+34 = 253

Now we will divide by the number of numbers we have there are 9 numbers.

Soooo.

253/9= 28.1111111

(Round)

28

Answer:

28 1/9 or 28.1111... (0.1 repeating)

Step-by-step explanation:

20 + 22 = 42

42 + 25 =  67

67 + 28 = 95

95 + 29 = 124

124 + 30 = 154

154 + 32 = 186

186 + 33 = 219

219 + 34 = 253

253 / 9 = 28 1/9 or 28.11111...

Hope this helped!

Mark wants to fence 4 rectangular gardens. So we calculate the perimeter of the each garden by this formula

P = 2(L) + 2(W)

Total Length of the garden =

=

Length = 18.5 feet

Total width of the garden =

=

Width = 9.0 feet

Perimeter of the garden = 18.5 + 9 = 27.5 feet

Mark wants to fence 4 garden

Therefore, 27.5 × 4 = 110 feet.

Mark needs 110 ft. fencing to surround all 4 gardens.

Answer:

The answer is 4/1763 in fraction

In decimal, the answer is 0.001 rounded to thousandths.

Step-by-step explanation:

If you want to divide this, you will have to make this expression to a fraction

to 8/3526. Divide the highest numerator if the fraction can simplify. It looks like 3526 can only be simplified by being divided by 2. Divide 2 to each side of the fraction. You should get 2/1763 as a fraction.

Answer:

x=5

Step-by-step explanation:

4x + 8 = 28,

it's rather straight forward,

you would subtract 8 from the left side,

doing the same on the right.

now you have

4x = 20

x= 20/4

x=5

hope this helps.

Answer:

slope = -1/2

Step-by-step explanation:

From the graph, pick two points:

[tex](x_{1} , y_{1} ) (x_{2} , y_{2} )[/tex]-> (0, -2) and (-4, 0)

Slope = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]

so (-2 - 0)/(0-(-4)) = -2/4 -> -1/2

Answer:

the rule is y=x^3

Step-by-step explanation:

2 times 4=8

3 times 8 is not 27

1 times 1=1

2 times 4=8

3 times 9=27

1 times 1^2=1

2 times 2^2=8

3 times 3^2=27

Step-by-step explanation:

The average rate of the function is 4.

The average rate of change of a function f(x) over an interval [a, b] is defined as the ratio of "change in the function values" to the "change in the endpoints of the interval". i.e., the average rate of change can be calculated using [f(b) - f(a)] / (b - a). In other words, the average rate of change (which is denoted by A(x)) is the "ratio of change in outputs to change in inputs". i.e.,

A(x) = (change in outputs) / (change in inputs)

= Δy / Δx

= [f(b) - f(a)] / (b - a)

given function:

f(x) = -x² + 6x + 12

Now,

let a= -3, b = 5

and, f(b)= -(5*5) + 6*5 + 12

 =-25+ 30 +12

 = 17

f(a) = -(- 3 * (-3))+6(-3) +12

  = -9-18+12

  = -15

Now,

f(b)- f(a) / (b-a)

=17 -(-15))/5-(-3)

=32/ 8

=4

Answer:

x=12 the other answer is 144.

Step-by-step explanation:

You set the expressions equal to each-other which gives you what x equals. then you substitute that in the A expression which gives you 144

Multiplying a matrix by a constant scales every entry in the matrix by that constant:

The difference quotient for f(x) = 3x2 – 12 is 6x + 3h

The function is given as:

f(x) = 3x^2 – 12.

Calculate f(x + h)

f(x + h) = 3(x + h)^2 – 12

The difference quotient is then calculated using:

[tex]f'(x) = \frac{f(x + h) - f(x)}{h}[/tex]

This gives

[tex]f'(x) = \frac{3(x + h)^2 - 12 - 3x^2 + 12}{h}[/tex]

Evaluate the difference

[tex]f'(x) = \frac{3(x + h)^2- 3x^2}{h}[/tex]

Expand

[tex]f'(x) = \frac{3x^2 + 6xh + 3h^2- 3x^2}{h}[/tex]

Evaluate the difference

[tex]f'(x) = \frac{6xh + 3h^2}{h}[/tex]

Evaluate the quotient

f'(x) = 6x + 3h

Hence, the difference quotient for f(x) = 3x2 – 12 is 6x + 3h
