Answer:

7

Step-by-step explanation:

We\ know\ that\\ Mean=\frac{Total\ Sum\ of\ observations}{Total\ number\ of\ observations} \\Here,\\Total\ Sum\ of\ the\ given\ observations\ are :\\9+9+2+8+9+8+7+8+3\\=63\\Total\ number\ of\ the\ given\ observations\ are :\\=9

Hence,\\Mean=\frac{63}{9}\\=7

Find the slope of the line that passes through the coordinates (3,-6) and (-9,2)
JulsSmile [24]

9514 1404 393

Answer:

  -2/3

Step-by-step explanation:

The slope formula is useful for this.

  m = (y2 -y1)/(x2 -x1)

  m = (2 -(-6))/(-9 -3) = 8/-12

  m = -2/3

The slope of the line is -2/3.

__

The graph shows the two points and a line with a slope of -2/3.

Find the slope of the line in simplest form.
N76 [4]

Answer:

-\frac{3}{2}

Step-by-step explanation:

To find the slope of the given line, slope is the rise divided by the run of a line.

  Slope  = \frac{y_{2} - y_{1}  }{x_{2} - x_{1}  }

  Picking points (4, 18)  and (8, 12)

 Now;

  x₁  = 4

  y₁  = 18

  x₂ = 8

  y₂ = 12

  Slope  = \frac{12 - 18}{8-4}   = -\frac{6}{4}   = -\frac{3}{2}

Will fan and medal! Identify the transformations that describe the graph of an even function select all that apply.
lara [203]
2 is the only right answer.  If it has right/left symmetry, then f(-x) = f(x), meaning it's even.  
extra info: 3 and 4 are the same thing
5 works for odd functions (like sin(x))

How does the graph of g(x) = −(x + 3)^4 compare to the parent function of f(x) = x^4
kotykmax [81]

Answer: Option D

g(x) is shifted 3 units to the left and reflected over the x-axis.

Step-by-step explanation:

If we have a main function f (x) = x ^ 4

And we perform the transformation:

g (x) = f (x + h) = (x + h) ^ 4

Then it is fulfilled that:

If h> 0 the graph of f(x) moves horizontally h units to the left

If h the graph of f(x) moves horizontally h units to the right

If we have a main function f (x) = x ^ 4

And we perform the transformation:

g (x) = -f(x) = -x ^ 4

Then it is fulfilled that:

The graph of g(x) is equal to the graph of f(x) reflected on the x axis

In this case we have to:

g(x) = -(x + 3)^4 and f(x) = x^4

Therefore h=3>0 and g(x) = -f(x)

This mean that: g(x) is shifted 3 units to the left and reflected over the x-axis.
