It should be A. Normal Distribution.
Answer:
10) x=90
9) x=20
Step-by-step explanation:
x+2x=180
3x=180
divide 180 by 3x=90
straight lines add up to 180 degrees.
9) x+8x=180
9x=180, thus 20.
<h2>Answer </h2>
$96
<h2>Explanation</h2>
Let Margo's pay check
We know for our problem that she spends 0.25 of her pay check on a new dress, so she spent on the new dress. We also know that she spends 1/8 = 0.125 of her paycheck on shoes, so she pent on shows. Finally, we also now that she spends another $24 for total expenses of $60, so:
Now we can solve for to find how much was Margo's paycheck:
We can conclude that Margo's pay check was $96
Answer:
Axis of symmetry: x = –1; Vertex: (–1, 0); f(x) = –2x2 – 2x – 1
Step-by-step explanation:
What are the vertex and axis of symmetry of the equation?
The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a .
$2.6, multiply 13 by .2 and you get 2.6
